It’s getting hard to avoid Monsanto (and other franken-foods) in the grocery store. But apparently even if you grow your own vegetables in your own yard, you’re still not out of the woods. Monsanto owns 40% of the packaged seed producers, too.

Fortunately, people with a lot more research time than me have figured out which seeds to buy… which companies haven’t been overtaken by Monsanto.

Today I planted two serrano pepper plants, two viva italia plants, and one roma tomato plant. I might have purchased more at The Natural Gardener today if it hadn’t been too close to the boy’s nap time and he hadn’t been melting down. At least he posed for a few cute candids before the melting began:

I’ve been harvesting three types of kale, swiss chard, and broccoli recently. I had a delicious meal of these with my friend Susan on Friday night. We sautéed the greens with garlic and olive oil, and then added garbanzo beans and a few other seasonings. I think we were both high on all the vitamins.

Also did some work on some structural stuff… added some brick to the walkways and removed more grass. I also created a small bed edging with beer bottles. I experimented with this a while back, but hadn’t used it anywhere until now.

Overall a pretty productive day, though it always seems there’s more to do.

This was an off weekend for CAMN classes, so I led a small group out on JJ&T for some fence monitoring. We logged 6.25 hours and repaired one intentionally-cut hole in the fence. Along the way, we heard a male golden cheeked warbler, saw a red and yellow striped snake hanging out underwater, watched two dung beetles rolling their prize, and saw numerous interesting plants. I’m really enjoying getting to know my fellow master naturalists, and enjoyed hiking with inquisitive, intelligent people.

And it was nice to see this after so many months of punishing drought:

Unnamed Creek

We’re supposed to get a new deluge of rain tonight, but I’m a little reticent to revel in that. I could jinx our chances.

That said, I got all the leaves mulched into fine particles suitable for direct mulching or the compost bins. I made perhaps 6 wheelbarrows of fine leaf litter, some of which went around the raspberry and blackberry canes. Much of the rest went into the compost bins, where I turned it in to be amongst the happy microorganisms that are already burning overtime to create some rich soil.

I finished my rain barrels last week in time for anything that might happen tonight. I’m really happy with the setup. Two barrels, a small length of garden hose between them, and some swank brass spigots. They are happily leak-proof after the application of both silicon and construction adhesive. The best part is that the pair of them cost about $70. And that includes the concrete block-and-brick bases.

I have radishes, lettuce, onions and carrots in progress right now, as well as some baby kale, cauliflower and broccoli. I probably could have planted these earlier, but they seem happy for now, and the radishes, for one, appear nearly ready for harvest.

My old makeshift rain barrel platform (constructed of pieces of old pressure-treated lumber) was sinking into the ground, and my rain barrel was listing. So I got a few concrete blocks, some spare brick, and a couple 24″ pavers and constructed a new one:

It is very sturdy, level and ultimately reusable. Nothing is mortared together – just heavy enough to stay in place, even if the barrel is empty of the 440 pounds of water it could hold.

I arranged the blocks in such a way that toads and other small critters have an opening to the interior and can access the inside and hide out in little “rooms” formed by the different blocks.

I want to go back to the homebrew store and buy another barrel. I’m eager to double my capacity.

I have mentioned more than once I want to incorporate chickens into my garden work. I’ve collected materials for the coop construction – cedar posts, scrap tin roof material, etc. – in an effort to use as little new material as possible. After all, one aim in doing this is to be as resourceful as possible in reusing materials. And to keep costs down.

Since Austin is hurtling toward heavier restrictions on outdoor watering (Sept. 6 if our rainfall doesn’t improve), I’m considering a rather drastic experiment – no supplemental watering of anything in my yard.

This more or less means no Fall vegetable garden. But it will be an opportunity to see how tough my various natives are. And if I lose some St. Augustine grass in the deal, so much the better.

I was rather spooked by an article in the New York Times yesterday on the possibility that Texas could see another decade-long drought – it has seen droughts lasting as long as 50 years in the past – and that what we’ve endured so far this Summer could appear mild by comparison.

I’m trying to convince my family to accelerate our plans to move to Portland. So far no success.

I’m nothing if not a do-it-yourselfer. I love the challenge of taking stuff I already have and finding the best way to make something useful out of it. Part of this comes genetically – my grandfather was, and my father is, crafty this way. And like them, I keep a lot of salvaged stuff around so that I have options when it comes time to make something.

But one project eluded me – a rainbarrel. It’s been hard for me to locate a source of barrels suitable for tinkering. Most sellers know a finished rainbarrel sells for between $100 and $200, so they tend to price empty food-grade barrels accordingly.

Back when I wanted to make fresh mozzarella, I stopped by Austin Homebrew Supply since they are apparently the only place in town supplying the ingredients for cheese-making. However, they sell empty 55-gallon barrels very cheaply, as well. They have a supply of them because they sell beer-brewing malt syrup in bulk. These barrels are a very sturdy blue plastic with a metal ring and rubber gaskets to seal the top. I bought one on the spot the last time I was there.

It didn’t take too much tinkering to create a functional rainbarrel.

First, I had to clean the leftover malt out of the barrel. Because malt is basically a sugary syrup, this was a pretty pleasant-smelling – if sticky – task. I didn’t use any soap, and all of the leftover water, I poured directly on parts of my garden.

I drilled a half-inch hole near the base of the barrel to accommodate a spigot. I had a cool, weathered brass spigot leftover from who-knows-where.

I also had an appropriate gasket and half-inch nut for the inside to secure the spigot.

Next I cut a hole in the lid of the barrel. The lid already had two threaded 3-inch holes in it, but I needed something bigger to be able to use a proper downspout diverter ($8 at Home Depot). I used my Skil saw to cut a hole in the lid that matched the diameter of the downspout diverter. I had marked this with a Sharpie.

Inside the lid, I fashioned some metal window screen as a catch-basket for debris and mosquito larvae pouring in from my downspouting. Currently, zip ties hold it in place, but I may use a stainless-steel hose clamp in the future. Cleaning the trap is done by removing (and inverting) the barrel lid steel hoop and the diverter assembly.

I built a stand for the barrel using some pieces of 2×6 lumber and cedar fence slats. It’s not gorgeous, but it does the trick of elevating the barrel 18 inches to give me head pressure for watering parts of the yard. The wooden part of the stand rests on some concrete pavers to help reduce the chance the wood rots.

So far I’ve spent a total of $28 to make it. It’s not perfect, though. What this barrel is lacking is any form of overflow arrangement, or way to connect it to a second barrel. Adding a second barrel would be nice since 55 gallons doesn’t go far. I want to figure out a better way to connect the spigot (it leaks a tiny bit). Also, I didn’t remove the St. Augustine grass from below the stand. A gravel base beneath it might be tidier. In April I made a concrete block stand for a friend, and I might try that model in the future. Concrete blocks are cheap.

Still, we’ve had a couple brief downpours since I built this barrel, and even a few minutes of rain fill it completely to the point of overflowing. Now if we’d only have a few more.

This week I got the chance to attend a private tour of the properties that comprise the 2011 Travis County Master Gardener’s Association Inside Austin Gardens tour. Given that I’m unemployed, the weekday-date of this preview tour wasn’t as daunting to me. All in the name of professional development, networking and inspiration, right?

Jenna and I went on this tour in 2009, and I still borrow ideas from the gardens from that year (Cheryl Goveia’s garden of art and whimsy being the stand-out property for me). So, I wasn’t going to attend this year’s tour on the actual date (Saturday, May 14), but the private tour afforded me a chance to experience the tour without toting the tot (who, recently, has made this type of hopscotch travel difficult.)

The theme of the tour is water-wise gardening: increasing rainwater infiltration, rainwater catchment, xeric plantings, etc. I can say some wonderful things about all of the properties with relation to that and other aspects of gardening. Each had significant strengths, and a wealth of stealable-ideas. I loved Rebecca’s tenacity at transforming her yard one small bed at a time to the point she no longer has grass. I appreciated the sheer lushness of Sue’s garden, and the tip about “cemetery rock”. And Sheryl’s garden was an oasis of low-water ideas, even with its lush vegetable production areas. Oh, and did I mention her enviable water collection systems? Yeah.

But I definitely wanted to focus this entry on Link Davidson‘s creations. (Oh, and if you missed this energetic self-described ox of a designer, catch him on CTG from this past week. (And if you watch his interview, stay a little longer in the program for a few photos of mine CTG used.)

Technically, the property on the tour is Wendy’s, and was created with her interests and aesthetics in mind. It sits next door to Link’s property, and he has fused the two landscapes into one by continuing certain elements between the two. A dry creek bed reminiscent of Wendy’s love of the Barton Creek Greenbelt, for example. This feature rolls gently downhill from Link’s property before heading south through Wendy’s. Naturally it ties the two together visually, but serves as a channel for run-off and rainwater infiltration for the surrounding plantings.

Another feature, a cut concrete path, conjures up Wendy’s desire that as much material be reclaimed and reused as possible. To that end, Link cut the formerly-straight sidewalk into rectangles and squares using a concrete saw, and then moved the pieces into a curvy stepping-stone arrangement with generous space between for granite gravel. Additional pieces he tipped on their sides and used for varying vertical interest.

Steel compressor tanks and rusted, bent metal edging have been used to add other sculptural elements to the space. Many of these things were scavenged on Austin’s bulky trash day, and turned into pure art. As Link said, if he can’t get it out of the trash, it had better be on clearance at Target or Home Depot.

And while it’s probably not kosher of me to say too much about HIS yard, which we also toured, I’ll post a few photos of his space on my Flickr account to give you an idea of the depth of this man’s creativity. Needless to say, I was blown away at the artistry and resourcefulness at creating highly-inspiring spaces on a budget. I’m sure in some weak-kneed moment I heard myself tell him we were kindred spirits.

For some time I’ve lamented that I never manage that seemingly perfect mix of compost heap ingredients that yields a little backyard furnace of thermophilic microorganisms, the one that keeps me from spreading weed seeds all over the yard (I’m damn tired of Arizona ash, sunflower and frostweed sprouts everywhere). I vowed to do better with composting this year, but wasn’t really doing anything systematically better to get there.

A week ago, however, I went to bury some kitchen scraps in the pile and flipped over a layer of organic detritus and discovered… heat!

The temperature needs to be a little higher… 135-160 degrees is the optimal temperature to destroy seeds and pathogens (not that I suspect THOSE are a problem… yet). Could be I need to get more air or moisture – or less – into the mixture.

But I think I stumbled into the right mixture of “green” to “brown” materials for the compost heap quite on accident. And a way to reproduce it in a somewhat reliable way. Last week when I mowed the grass for the first time this season, I had a bag of scavenged mixed oak leaves and grass from another yard I was mowing near. The bottom of the bag had rotted out, and when I went to move it, the leaf mixture spewed forth. Did I bother to rake it up? No. I had my gas-powered vacuum cleaner already running, so I kicked the leaves around and mowed them up. Since it’s a mulching mower and I bag the clippings, I had inadvertently created a really good mixture for the compost heap, probably achieving close to the 30:1 ratio of carboniferous to nitrogenous materials.

But it has been exceptionally dry here, too.

So, to help with that, I’ve been allowing tap water to sit in white plastic jugs. This allows the city-provided chlorine to outgas and prevents it from damaging the microbial community in the compost heap. Every week I dump a 5-gallon jug into the heap to help keep it moist. I generally turn it (or at least give it a good prodding) on the same rough schedule so it maintains some oxygen.

Last night I checked the temperature again, and it had fallen to around 110?. I suspect a lot of the nitrogen-bearing grass has been used up. It’s getting close to time to mow again, so I’m definitely going to toss in more leaves as I do.

And if that doesn’t work, I might resort to peeing in my compost pile.

I get to this time of year and I want to build things: structures, landscape forms, garden beds, walkways. It never fails. But so much of the work is seat-of-my-pants with materials I have on-hand. Which, usually, is fine by me. I like improvising and coming up with something innovative with what’s on hand.

But there is one project I just don’t think I’ll be able to be that… haphazard with: a chicken coop. I’m certain I will have to draw out some plans and be very intentional about materials and form.

To that end I actually sat down and sketched, to the best of my ability, a plan for a simple trellis structure to help give our yard some privacy on the south side. That side has our Miami Beach wannabe neighbor, and I just don’t want his pimp-daddy self to have visual access to our yard. Especially since he’s a little hostile and pretty much anathema to everything about organic, sustainable gardening.

So, the drawing is to scale, and does a pretty good job of letting me know what my bill of materials and costs would be. It would be rough-hewn cedar, hardware cloth, and coral honeysuckle. It would replace my ghetto bamboo trellis. And I drew all of it with a dull pencil, a ruler and scrap paper (‘cept the part I fixed in Photoshop after I scanned it).

I have rarely engaged my mechanical drawing skills since high school, but a lot of it came back naturally. Maybe I have a fighting chance with a chicken coop.
