bob – Welcome to Bob's Garden

photo update 07 2020

Usually I pick a theme and possibly support it with pictures, This post is going to just show pictures with brief descriptions, and maybe a theme will develop

exceptionally warm weather early, the bananas were suckered into coming up early, and then were hit by several hard frosts, still, they managed to thrive. I transplanted about three backhoe buckets of roots this spring down to the middle swale and those bananas are also thriving. I like banana leaves for mulch applications to control weeds.

Now, if you look close there is a wire cage (lower left), protecting a slew of hot peppers just put in where bananas used to be.

Backhoe, front loader bucket needed welding, seems like with machines there’s always something. This is not the only repair this year, but the backhoe got some good use when I was digging swales , pulling stumps, planting trees. I don’t mind a little TLC for all the work it does.

This is the middle pond after a heavy rain, note the limestone gravel at the back of the dam, any water running down the gully gets filtered through that limestone, and this year the water has been much clearer.The muddy water was temporary, due to 5 inches of rain in a 24 hour period.

This is a snake I’ve been watching for several years down in the gully ponds, and he started foraging up to mylittle ponds near the house. Whe I found out what he was doing I was trying to figure out what to do, little goldfish were disappearing rapidly, how soon would he start to look at the koi? The problem solved itself, he got caught in a stray piece of chicken wire and died For the time being the koi are safe, but how soon will other critters come by to threaten them?

This was the little Koi pond back in April,

Here’s the pond in June, Elephant ear tarot, tumeric,lemon grass, sage,lemon sage, banana, lemon verbena, ….. There’s even a place for marshy plants that like their feet wet, bulrushes, snake plants and most recently some horsetail starts.

cruciferous aren’t fond of the heat, but i’m still harvesting kale, broccoli, and I think there’s some cabbage in those overstacked plants.

This is the biggest pond, and the highest. Not as much rainfall this year, so after building it about 6 feet higher and a good deal wider as well, the dam is cracking a little–from the dry conditions, The arch of black pipe there is meant to be an irrigation pipe, and when the dam fills, it will send water anywhere it needs to go. When the pond finally does fill the green vegetation lower left corner will be underwater, and at its peak even the vegetation upper left, and several feet of the vegetation on the right side will also be underwater.

This pond also has some new mulberry trees planted on both sides, and to the left of the water level is a long area partially shaded where a new garden is taking shape. several tomatoes and peppers are planted to start conditioning the soil, but also a blueberry, grape vine, and kiwi have been started to be part of the perennial crops there. Even the top of the dam, which is clay, got a few mounds of topsoil and watermelons are planted there in full sun.

It is a Wardrobe!

Bill Mollison described a class he was teaching and a stranger who lingered on after the meeting, who looked very much like Karl Marx. The stranger said you know what you’ve done, you’ve arranged all the elements of life in good order in a wardrobe or closet.

Bill seemed to like that description about how Permaculture made good order out of all the different elements of life on earth. Others might say it is a toolbox . One may use hundreds of different tools and tricks along the way, and in the end the result hoped for is improvement of our lives and the health of the earth as a whole.

I have heard people criticize the idea of saving the planet, the earth has been here for millions / billions of years, and short of a black hole it will continue on in the blackness of space, with or without us. We are simply fleas riding on its back. The issue here is not saving the rock that is the earth, it is saving the earth’s systems for the people.

To that end, Permaculture continues to collect those methods and tools that will help the earth continue to sustain us as a species.

Big Developments

It has been some time since any substantial developments and I’d like to talk a little about the psychological side of this work/ fun. Many of these techniques are as yet unfamiliar here in the states, so implementing them is more a question of trust or belief, or possibly just being able to grasp the theory and take it to the level of practice.

No matter how reasonable any theory may sound I still have that element of “show me”. I need to have my hands or attention in it to really understand any new principle, and when it comes to water management there is a great deal of faith involved when investing thousands of dollars in a system, not to mention time and energy, in order to get things started and working.

Even after systems are up and running it can often take years before any visible results are observed. With this in mind I went ahead and hired a forest mulcher to facilitate the next part of my water management system.

For those unfamiliar with clear cuts, around here there is a massive pulp wood industry, that relies on fast growing pines and miscellaneous deciduous trees. For me , unfamiliar with this industry, I thought I would have to start planting trees on a property with nothing but briars everywhere., but here in this climate trees regrow almost immediately, some from seeds or low sprouts, but often from the stumps left behind.

This means several sprouts from each stump and other seeds all competing for light, shooting up fast and tall and thin.So these trees are efficiently harvesting light, sequestering carbon, but producing little in the way of useful lumber or fruit.. Also, removing 20-40 years growth when the trees were cut does not improve the soil quality as much as if the tree had simply fallen and rotted into the ground. So soils around here would not be that good for regular orchards or quality tree systems.

A friend suggested 20 years ago that I should walk around with a sharp machete cutting off extra sprouts to make the remaining trees stronger, At the time I didn’t know about Permaculture, had no extra money to install special dams or swales, and spent all my energy off the land just trying to pay the mortgage.

It is into this tall thin jungle of trees I went on different occasions trying to build ponds and swales with a backhoe. Yes, it can be done, but it is tedious and time consuming. So after surveyors marked my property line, yesterday I had a forest mulcher come through and clear a path about 8 feet wide that outlined the boundary and then followed various contours around the land scape.

Recent windfalls financed this project, and this is the big development.It is quite unusual to see a landscape change so dramatically over the space of a few hours. The boundary line painted by the surveyors now has a sight line hundreds of feet long, and actually seeing the contour paths cleared gives many new insights into the actual “lay of the land”.

Of course keeping my backhoe running through this next phase will actually allow the project to become functional, but overall just having the paths cleared to give the backhoe freer access should make the project move much faster with better results.

One unexpected outcome was the nature of the soil left behind. I expected wood chips, but the mulcher did more than that, it also mixed up the top soil and left behind a rich resource of garden soil that will soon be installed in my gardens and likely create many new ones as well.

It’s like turning a corner, or moving to the next level of productivity, what an exciting time!

Managing Hot Water

Talking with a weekend friend the other day who is starting to contemplate country life full time, she mentioned it had occurred to her in the shower the other day just how nice a hot water shower can be. In fact, she continued, she believed it to be an essential element for survival.

I added to her declaration that the shower needed to be at least under 45 lbs of pressure or I could never be satisfied. But I said this after a summer of almost entirely cold showers with no hot water at all. This was mostly by choice, but the best hot water heater I had during the summer would have also heated the house, which would have just added to the cooling issues of summertime.

When I first came here 18 years ago I had a gas hot water heater in my RV, and that was ok sometimes, but in winter, with freezing pipes; often that hot shower–or any running water at all, was unavailable. Still, even back then I understood how valuable hot water could be, and have spent a fair amount of time over the years making sure I could cover that need.

For several years now I have been heating water with wood. It started with a small Appalachian style coal(wood) burner water heater attached with a thermosiphon to an old water tank. Fire it up and maybe add wood a couple times and then close the pressure relief, turn on the 12 volt pump and shower as long as I wanted.

I also used to play with 2-300 feet of black poly pipe in the sun to avoid lighting fires in summer. Now that I am in this house (I use the term loosely), the ease of that little stove or even the poly pipe in the glass covered box are unavailable. And my aspirations have moved further on.

I still am heating water with wood, but now it is a sophisticated rocket stove, and every year there’s a new type to play with. It started with copper coils on a 55 gallon barrel, and now it is a 20 gallon tank inside a brick and clay “bell”, extracting heat from the DSR.

I’m actually quite proud of all the different ways I have played with producing hot water, and the latest toy should be arriving soon, an evacuated tube solar water heater. True to form I will not be following recommended procedures, and perhaps I will waste a little time reinventing the wheel, or perhaps I will find a way to make do with much less than the recommended equipment.

I have already found I can get by with smaller pumps and less energy and still enjoy similar results with many of the much more elaborate and expensive solutions.The new solar project will be a similar process, finding out the extent of it’s capabilities and then making use of them

When I built the house I did anticipate the possible use for radiant water pipes in the floor, although with my limited budget I had no idea how I might generate that much hot water, or even how I might get it through the pipes. Today my budget is less restricted, but continuing in the use of renewable resources puts a whole different spin on things than just buying a new propane hot water heater complete with expensive automatic controllers and pumps.

For the time being the solar collectors I’m playing with are more an experiment than a completed plan, but they do seem to have enough promise to invest in, and then fully explore their potential here.

One of the keys to Permaculture Design is to have several backups for every important system, and since hot water is one of those systems I continue to investigate and establish multiple ways to generate hot water.

DSR 2019 build

Well, a new heating season is begun and with it a new iteration of the previous Rocket stove, called a Double Shoebox Rocket.

The group over at the Donkey forum did some experimentation back in 2018 coming up with this concept, which was later abandoned by Peter van den Berg, the chief experimenter on the project, as being too unreliable.

By the time he had moved on to a different design I had already started building, it was getting colder, and looking at the elements that seemed to make the DSR run away with the burn, they did not seem as relevant to my design, so I just continued to build according to his best guess dimensions.

My 2018 build used a number of walls that were simply formed of clay, or a clay perlite mix, and a couple of the sides around the water tank were taken from an old washing machine, with some fiberglass insulation hastily fastened to the inside of the walls, with clay slopped around the top and edges to give a seal.

The door to the burn chamber, as in many projects done on the cheap was a problem until I finally bought a couple pieces of neoceram stove glass, which cost more than all the previous stoves from the last several years.

While this new glass has proved very durable, having a door that really is robust requires more than just a glass pane, so that is still in the development phase, although I’m pretty sure I have a workable solution which will likely happen sometime during this season. For now I continue to get a potholder if the glass is hot, and as gently as possible remove it and then wedge it back into place.

The other main change is the use of bricks to give a substantial continuous exterior that is well sealed and even looks a little better.

One other important note, my exhaust was set up for a low temperature ground level “stack” and to use the push of the j tube rather than the pull of a draft. Since the first batch box conversion about three years I found it necessary to install a fan at the end of the exhaust pipe to aid with the draft. This totally eliminates smoke at start up and keeps the draft more even.

while it may appear the smoke is being pumped into the ground, the downward tube is actually wide open at the seam, this arrangement helps prevent sudden gusts from totally disrupting the draft

The brick exterior is continuous back to the poured concrete wall as I continue to remove clay from the previous construction. the removed clay goes right back into the new build

note the wet perlite clay mixture formed in place around the DSR core. The stack/exhaust is on the floor at the right side of the shovel

the clay perlite insulation layer continues across the concrete wall in back

The second chamber is now well defined and the brick courses are starting to grow

Note the rectangular passage on the right where the exhaust comes in to the first bell from the secondary burn chamber. The rim of the duct to the water tank “bell” can be seen just opposite this entrance and further down in the chamber

The right side of the water tank shows the location of the duct from the first bell just visible above the top of the front bricks

overall layout of stove. note exhaust moves from right to left through the chambers and at the bottom of the water tank chamber it turns back and flows under the construction to the exhaust “stack”

salvaged glass stove tops are sealed with wet clay to the top. Note the left side galvanized pipes exit and the blue pipe insulation for the hot water outlet

proof of concept, the first fire verifies the exhaust, now the drying process begins

looks just like the pictures I saw when I first started last year, note that the bricks are joined with a clay “mortar”, if I want to rebuild, everything is easily recycled with water as the solvent

I usually have a small piece of ceramic fiber board over the glowing section of the stove top. Temperatures are way hot, and after passing 1000 degrees F it just registers as “HI”

cooking can be done here, very carefully, but I like the idea of more insulation to increase efficiency of the burn. The second chamber still has plenty of heat for a more reasonable cooking surface, and even the water tank chamber can keep things warm

DSR (Double Shoebox Rocket) revisited

So it’s getting pretty cold outside, and when I built the last version of my stove I promised a breakdown analysis after I had used it for a season and had a chance to sort out my experience. Now that I have rebuilt the beast it seems the time is here to write about it.

First I would say that overall it performed pretty well, the weakest part of the thing being the door. The visions cookware lid I started with did work, but I would not plan on using such a thing except in a pinch. Eventually the first one cracked, primarily from physical shocks because it really does get too hot to handle at times leading to bumps and drops, and once hot it will use any excuse to crack.

Over the three to four month life of the stove there were numerous tweaks and while the final product worked, it would never have lasted another four months without many more overhauls.

My building style was primitive, using lots of clay and perlite, which was always sufficient in the original rocket stoves I built, but with the more compact and intricate design of the DSR bricks are really the way to go for all vertical surfaces, not just inside the firebox/batch box. Also bricks give an element of speed to the construction, and the finished product is structurally more stable. With clay walls on much of the old stove, cracks were commonplace, and I often worried about them just falling completely apart. If you do want to use clay, make sure it is a continuous mold type process. Forming one wall one day and then adding to it or building an adjoining wall the next does not give a reliable bond.

The water tank was the next area of interest, primarily because it was an issue I had to revisit many times, especially after one spectacular failure. My theory that pex could withstand temperatures in excess of water boiling was good only to a point . Hot, therefore soft, pex under extra pressure will blow out. Use all metal fittings inside the heat chamber and for a distance outside the chamber, and of course, when heating water, always have the system open so steam can escape safely. Pressure relief valves are a real good extra insurance in case one forgets to depressurize the system.

Soot was present everywhere the exhaust touched , except the parts that got the hottest in the burn chambers. The thought occurred to me that I had basically turned the entire downstream part of the stove where heat was extracted into a creosote trap, and future builds will have to accommodate an easy access for periodic cleaning.

Future builds will also need to be more efficient, and since start up and cool down phases of the burn are the most problematic, shortening those periods compared to overall burn time will be a major concern. Quality dry fuel will become a major goal for operation of the next iteration of the stove.

Recently I read more about the continued development of the DSR II and it has taken some interesting turns. I’m not sure I will be using all the developments, but at some point I will likely be adding a short riser at the back of the firebox. That will likely wait for me to get some ceramic fiber board, so for now I’m just using the old DSR design.

original visions lid, the crack is visible on the left side running under the handle, and I continued to use it till it cracked into several smaller pieces later on

this hodge podge is the water tank enclosure As the winter closed in, my hurry to get the stove functional meant many makeshift connections and very iffy seals. The forced draft kept a negative pressure inside the stove so leaks weren’t really a problem, but it would always be best to have everything tight as a drum

I broke down and bought a 10×10″ piece of neoceram glass–expensive (50$) but a good investment

this is before the old stove was finished being built

taking the stove apart, note the soot in the oven chamber but not the firebox area

getting a start on the base of the next DSR, note the exhaust has been extended and turned toward the left in preparation for the changed position of the water tank and the exhaust exit from the stove

I was a bit remiss taking pictures as I dismantled the old DSR, and obligations elsewhere meant much of the new construction was not overly documented, but look at the next post to see how the new DSR changed.

Fall?

This has been a drastic change from last year when it was too wet to do much. This year it has been very dry, and instead of water, dust, dry powdery clay is the issue.

It’s kind of interesting to watch the tendency of the mind to be so centered on the moment and when right in the middle of a situation things can seem so permanent that it’s difficult to remember there can be another condition. When it’s dry for a long time it’s hard to remember the water, and when it’s wet, it’s hard to believe things will ever dry out.

Puts me in the mind of the Arkansas Traveler, and the man with the leaky roof who doesn’t feel need to mend it when it’s dry, and when it’s wet it’s impossible to mend it. The end result is the roof continues to leak.

But here that isn’t the case, I’ve had the backhoe in several places that would be impossible in wetter conditions. I went down to the oldest goldfish pond where I couldn’t begin to go last year at this time. With a firm footing underneath the backhoe can go more places and dig out ponds deeper and wider, with less mess.

Creating deeps in a pond is important for many reasons. It gives fish a place to hide to escape predators, provides protection from cold and heat, and also reduces surface area evaporation in extreme drought, giving the fish that last refuge when everything else has dried up.

Regardless of the purpose of the action, there seems to be a strange relationship between the opposite conditions, and often the solution for one extreme is found when the pendulum swings in the other direction.

When it is too wet it’s easy to see where water has found weaknesses in the design, when it is too dry it is possible to rearrange and correct the design for the next time when water is in abundance.

Close to 100 degrees yesterday, 80 today, and barely 70 tomorrow. This feels more like August than October. Just writing it has me even more amazed at the extremes.

It’s tough to keep the few plants left alive watered and with dwindling reserves and little rain in sight everything must be rationed. The middle dam gave some water to the goldfish pond, the small garden pond donated water to the pepper plants, and the catfish in the upper pond have to do without as I watch their pond recede.

Since dry clay does not compact well, backhoe work is limited to establishing the filtration system for the middle pond, and spreading gravel on the driveways.

Dry weather is a good time to work on the driveways, so scraping the drive on the front side of the creek yielded several loads of pine needles and wood chips for the gardens from the other side of the creek, and then adding gravel helps them become more even and dependable for wet weather that will eventually come.

The one area near the middle dam was a creative event to gather more clay for the middle dam, and the sharp cliff that was left will hopefully establish a micro climate for many of the fig trees that have been living in the green house. It’s time to put together mulch and soil there so they can be replanted for their first unprotected winter, and sand and wood chips with salvaged top soil from the pond sites will be primary soil builders for them. A little compost will help as well to contribute lots of soil organisms.

They will also get a very heavy mulch of leaves once planted and with some luck become a regular fig forest.

This post has now officially become a running commentary on the last several months. With other imperatives in my life aside from these projects in Permaculture my house and gardens have suffered serious neglect, but with luck that will change in the coming week.

The dry spell has definitely broken, and I have been told my ponds are filling up. Looks like I may be waiting another year if I want to do any more digging on the upper pond. In fact, back hoe adventures may be severely limited to smaller projects and times when driving it from one location to the next don’t dig deep ruts in the ground.

Retreating inside or to hand tasks in the garden does have its advantages. Rest and planning are at the top of the list. It would be easy to get bored and start chaffing at the bit, leading to misadventures and more harm than good, so having a variety of projects, both inside and out can be a very good thing.

As the weather gets cooler, I’m reminded that the newest version of the rocket mass heater needs to be built. There’s always inside cleanup, and the roof skeleton definitely needs some more work. Not to mention finally fleshing out this post with the pictures it so desperately needs to continue a complete coverage of ongoing developments.

With that I will close, but pictures will be added soon and maybe this post will actually get published. 🙂

Hot and Dry

These are the times a good water system is vital, both for crops and natural systems. With my dams still just babies, and deliberately draining the top dam early on, the water level up there is going down fast–but not as fast as last year. likewise the middle dam is going down, but even now it is still higher than at it’s peak last year.

As the dams grow in height and excavation inside the pond winds down, I will be able to fill that upper dam and keep more water for a much longer time. the swales (once they are built) will keep the water in the soil saturating much more of the landscape.

In a few years any carbon I lost cutting young trees will be compensated by faster, better tree growth during times like this. Also of course, the garden will have ready access to gravity fed water once the pipes are buried and the siphon systems are in place.

Way back before I ever suspected a dam or high water storage, I installed an extra 3/4 inch pipe from garden to cistern. I never knew what it might do, and for a long time I thought it was wasted energy, but now that pipe will be one chain in the link of the coming irrigation system.

Also, looking at the top pond, it is very green- thanks to the catfish-algae that will make excellent fertilizer for everything. Soiled water may not be ideal for house uses, but the plants love it.

Anyway, this is the weather I’ve been waiting for, time to get the backhoe moving dirt from the back of the pond to the dam. I’ll also have to dig the sediment pond in back and establish some sort of small fish nursery/ fish food cultivation system.

I don’t anticipate much swimming in that upper pond, but a sediment system could also act as a filtration system just by adding a pump if swimming does become popular.

Entertainment

It has been an interesting week, going back to salvaging an older, but still quite nice entertainment center. Bringing more stuff back to my junk yard might seem counterproductive, but in finding a place and setting it up I had to clear an entire wall near the work area.

That particular wall seemed to have stuff that was difficult to move and get to, so it was difficult to even consider cleaning it up. The results however were great. That entertainment center is a nice addition, some places for storage, but more important, it is close to the wall and unlikely to creep further into the room.

Of course the real fun part (cosmic humor) was that my tv does not fit, So the original idea to create a functional station for many sorts of entertainment has a fatal flaw–at least partially, but then I started to consider an entertainment center I had salvaged years ago, but never assembled. And yesterday I played detective and csi investigator, matching holes and misc connectors until I had the whole thing put together in it’s original configuration.

That in itself was a great feat, and the tv fit, but the new old center was in much worse shape than the first one, and would need most of another wall to install, one already occupied with very intense storage. I took the radical step to disassemble and commit it to recycling, even to the extent of removing the quick connector studs and other recyclable parts.

And then I looked again at the storage wall. Numerous mismatched drawers and a couple sets of plastic shelves now partially displaced by the first entertainment center, and, with a rainy day ahead, it seemed the thing to do was to remove it all and build the work bench storage area I had always intended for that space.

So here I am, after taking a break from a quick tour of the ponds after about 3-4 inches of rain -everything working fine- and planting a few more pepper plants and weeding a bit, writing a blog and putting off the next steps which will involve doing an accurate jop on that wall, putting in better quality studs and securing the top plates in a more permanent way. Then it will be time to bring order back from the temporary chaos, the goal being an open work area, with easily accessible storage, and lots of stuff losing it’s place cluttering my house.

Wish me luck

Summertime

and the living is easy. Catfish jumping and the Kale is high.

I had purposely drained this pond almost down to this level, back when every next rain was washing over the top of the dam, now with the heat I wonder if the drain was a good idea, the water looks pretty bad as a stagnant pond, and I might rather have the high water, TWT

The grapes aren’t quite at the point of shielding the glass enough or cooling the air enough, so I put up the sheet again this year to keep the sun out of the greenhouse, maybe next year with a better trellis and more growth of the vines.
