Planting Time

As you may have seen from our previous post, we’ve gone all out for planting a raised-bed winter garden. In the prior blog entry, we go through the process of building the planters out of wood harvested from our own back yard and bolstered with our daughter-in-law’s no-longer-needed bed slats, and filling them with nutrient-building amended potting soil. We have great hopes that the planters will make it easier and better on us oldsters, to be able to maintain a home-grown garden. The planters are about waist-high, so we’re saying “no” to back-breaking shoveling, hoeing, and bending over to weed.

Today I picked out some winter veggies from our local Garden Center that are supposed to work for our growing season, although technically, I’m told the optimal time for planting the winter crop was last month. We will see if we can keep our little project going.

We have a couple of strawberry plants, various herbs, lettuce, arugula, broccoli, and a couple of different types of cabbage. We like greens, which would be an acceptable winter crop, but for me, lots of collards, turnip greens and kale are a dietary no-no (kidney stones).

Some sustainability experts say that it’s best that your garden is situated somewhere you’ll naturally see it and come in contact with it every day, like say, a spot you walk by on your way to go to work. These guys are out on the back patio, sort of hidden. If we open the blinds in the hall bathroom, we may be likely catch a glimpse of the planters if we happen to wander into that bathroom. Otherwise, it’s “out of sight, out of mind” for the garden. Maybe if we set the alarms on our cell phones each day to “go check out the garden” then our recent efforts won’t slide by the wayside. Sheesh! The ancestors had some valid motivations to tend to their gardens, such as “you want to eat some real food, don’t you?”

The weather report says we’re not supposed to have a freeze any time soon. About a week from today, it says, the temperature is supposed to go down to 35 F at night. The hay that we’re using for mulch will keep the moisture in the soil, and if it rains very hard, will prevent the dirt from splashing up onto the plants. Hopefully our shade cloth that is on order will get there by then so we can be ready to protect these little babies!

Building Raised-bed, Easy-water, Easy-weed Garden Planters with Family and Friends

My wife and I have started gardens in the past with a moderate level of success.  We have picked out a patch in our back yard, tilled the earth, worked in some potting soil and then after germinating some seeds, transplanted the seedlings and then watered and watched the bed to see what happened.  We found that the bugs liked our tomatoes, but didn’t like our squash enough to pollinate the squash flowers. Our food production was minimal.  And we hated having to bend over in the hot sun to tend the garden!  So when I saw Jon Peters’ YouTube video on constructing a raised bed garden, I was inspired to build a couple of these beds for our future garden efforts.

Urban Lumbering and Photovoltaics

We were fairly true to Jon’s design with just a few variations.  I’ll cover these variations in the following paragraphs but first, a few words on urban lumbering.  About four years ago, I entered into a contract with my local utility company with what is called a feed-in-tariff  agreement. Basically if I purchased a photovoltaic system for my house, the utility company would meter my power production and pay me $0.32/kWh for the next 20years. I received a 30% tax credit and was able to write off the cost of the system over four years. [I won’t go into the political ramifications of this program. I’ll save that for another rant on another blog.] So what has this got to do with urban lumbering?  In order to maximize our solar exposure to the photovoltaic system, we had to cut down some red oak trees and some pine trees.   Since I am a woodworker and a wood hoarder, I couldn’t bring myself to the decision of cutting down these trees and having them hauled off to the local wood-burning power plant.  So I called Lumber by Lance and Phil the Tree Guy and had them come to my house and turn these trees into beautiful stickered piles of lumber.  I watched as 4/4, 6/4 and 8/4 slabs of beautiful heart pine and quarter-sawn oak fell off the portable saw mill.

This project was perfectly timed, since one of my wood piles had air-dried for four years. We decided to not plane or joint any of the wood since, for this project, it was going to be used to hold a bunch of dirt!  

 Help from Family Sustainability Experts

Our two sons from Puerto Rico came home for Thanksgiving and wanted to help build the raised beds.  Our older son is the director of an educational  non-profit organization based in Puerto Rico, focusing on promoting sustainability and ecological agriculture, Plenitud PR (www.Plenitudpr.org or Plenitud PR on Facebook).  Our younger son is an instructor and project manager at the Plenitud farm and teaching center. This was just the type of project they live for!

We used the same dimensions that Jon Peters used, 36 inches by 57 inches. The boys found lengths of lumber from my stash that were approximately 8 and 6 inches wide. These were cut to length, and using battens cut from old bed slats, they were fastened together to form 14 inch high sides for the boxes that would make up the raised beds.  Hardware cloth (purchased at a local hardware store) came in 3 foot widths in a roll 10 feet long, just enough to make two beds. This hardware cloth was stapled to the bottom of the boxes with crown staples. Then 1×2 slats of wood were used to frame the hardware cloth for additional support. Before adding the 1×2 slats, pressure-treated 2×4’s were used as cross pieces to add additional support to the hardware cloth. Jon Peters had suggested that additional support might be needed. In a kit-build, Jon Peters demonstrated that another way to construct the bottom of the boxes was to use slats spaced with gaps for drainage.

We took a different approach for the construction of the legs. Jon used 32-inch lengths of pressure-treated 4×4’s.  He removed half the thickness of the 4×4’s for a distance of about 14 inches from one end of the board. This formed a step for the box to sit on. My experience with the current method of pressure-treating 4×4’s is that the penetration of the chemicals into the core of the wood is not always as thorough as it could be. We decided to go with two 2×4’s, one 32 inches long and one 18 inches long, glued and screwed together. These legs were then fastened to the boxes with 2 ½ and 3 inch Robinson deck screws.

The boxes were moved to the back yard deck. This kept the boxes out of the way of lawn mowers and weed eaters. Once located on the deck, architectural (weed prevention ) cloth was stapled to the inside of the boxes. This was to provide for a layer to retain the soil while letting water drain through.

Our Puerto Rico Sustainability Experts then stepped up and set about helping us put together a perfect growing media for the new raised beds.  The basic recipe for the soil mix was 40-50% organic matter, 25-30% perlite and 25-30% peat moss (not a sustainable component) or coconut fiber (a sustainable component). Our specific mix was comprised of Black Cow © (cow manure fertilizer as a source of nutrients), CocoLoco © (worm castings, coconut fiber, perlite and soil), peat moss, potting mix, and additional perlite.  This was mixed up on a tarp (see the YouTube video) and placed in the raised beds.

After filling each raised bed with the soil mixture, we added a layer of hay to the top of the soil mixture. This layer of mulch slows down evaporation of water from the bed and protects new seedlings.

Additional Support System for the Raised Beds

The next day we acquired some 10-ft lengths of ½ inch PVC pipe and clamps and constructed a support system for each bed.  The support will provide for shade (50% black cloth) during the summer months and for cover during the winter to protect the plants from frost.

Now on to the local nursery to pick out some fall/winter seeds and seedlings!
