The straw bale garden I planted in 2013: before and after.
I suspect we’re not alone in having tried just about every way to grow a vegetables garden. In the lifelong quest for decent home grown vegetables we’ve tried the methods of every gardening guru with a book: biointensive, biodynamic, raised beds, pots, self-watering containers, straw bales and just plain old by-the-book science-based, extension service advice. Results have ranged from moderately successful to moderately tragic–mostly moderately tragic.
Over the years, our vegetable garden has shrunk from ambitious proportions to a tiny 3-foot by 8-foot raised bed filled with tired and expensive potting soil. This past winter (our best season for veggies here in Southern California) I didn’t even bother to plant anything as I was busy working on the inside of the house. Last summer we tried, unsuccessfully, to grow tomatoes (due to disease problems built up in the soil over the years).
So when it came time to ponder planting something for the summer I reviewed past efforts to figure out what gardening method was most successful. Surprisingly, the two best gardens I’ve planted in the past were either biodynamic or straw bale gardens. I think Rudolf Steiner’s quirky biodynamic technique works not because of any material benefit from his witchy potions, but simply because his philosophy demands that you to focus intent on the garden, thus making the act of gardening a kind of sacred duty. But, this winter, I’ve still got a lot of tasks to complete and don’t have time to develop either a biodynamic compost pile or, gasp, thoughtstyle my way to some new, alternative method of sacramental gardening.
So I decided to try straw bale gardening again. My last attempt, that I blogged about and even did a video of, worked great. If you’ve never tried it, the process is simple. You get straw bales, water them, add nitrogen in the form of either blood meal (organic) or urea (conventional) for a few days and then let them sit for a month while keeping them moist. For the details, download Washington Statue University’s instructions. Growing in straw bales is also a great solution for folks, like us, with lead contaminated soil.
The drawbacks of straw bale gardening are mainly environmental. You have to buy bales and nitrogen and import them in a CO2 spewing vehicle, unless you have a generously sized cargo bicycle. And in my last straw bale garden some of the tomato plants showed signs (a lot of leaves and not a lot of fruit) of too much nitrogen. On the other side of that equation I grew some truly monstrous winter squash, enough to feed all the inhabitants of a generously sized cult compound.
This time around I’m trying an inorganic approach, substituting the blood meal I used last time for urea. I’m curious to see if I notice any difference other than price (urea is a lot cheaper). Should I try it again, I’m thinking of building some simple wooden boxes to hold the bales and keep them moist in our hot and dry summer season.
My previous success with straw bale gardening is perhaps a lesson in the simple fact that there is no one-size-fits-all formula for growing vegetables. Given that we have limited space, contaminated soil and other priorities right now, straw bales make for an easy way to grow a few summer vegetables with a high chance of success.
When figuring out where and how to plant a vegetable garden we’ve got to include both biological and social considerations, i.e. we’ve have to consider both plants and people. If you’ve got more space, time to compost and healthy soil roll with that. If you’re in an apartment grow some herbs in a pot on your windowsill. If you’re a dilettante appropriate technology blogger with limited time for gardening and a long list of chores, a straw bale and a bag of urea might be the best way to keep the kitchen knee deep in pesto.
