When we moved to Vermont, our ZIP Code sat in a solid zone four. Now it is comfortably into zone five, and we set out seedlings a week earlier on Memorial Day weekend. Our day and nighttime temps can still be a bit bipolar, so when it looks like the nighttime lows will be below 40, I cover the tender annuals. Yesterday morning, however, I learned that, with straw bale gardening, less protection can be more.
The straw bale method involves conditioning the bales with plant food and water almost two weeks ahead of planting. This causes the straw to break down, and you are, essentially, planting your veggies in a compost heap. Like most compost heaps, the decomposing bales Start to “cook”. This means if you cover your tender annuals, like I did with the cukes pictured below, you need to make sure that they are uncovered as soon as the sun hits your garden. As you can see, I slept in a bit yesterday, and at least one of my little cukes got fried.
It’s still early enough in the season and hot enough outside that I can direct seed it to replenish, but I hate to sacrifice a soldier that was trying to serve me well.
By contrast, I did not cover the summer and winter squash or the tomatoes. Those plants were slightly bigger, and I had only so much material for protection. It was down in the low 40s on Saturday night and Sunday night, and I knew I was gambling.
When I walked out to the garden in the morning, however, this was the sunshine that greeted me:
I took a little trip to the back of the garden to check on the tomatoes, and every single one of them was getting ready to salute the sun:
The tomatoes do have weed block around them, but the real heat is coming from the bales.
Later in the day I went back to visit the garden –– I visit to talk to the plants and the bees in the nearby apple trees a few times a day – and while I highly recommend talking to plants and bees regularly for your mental well-being, my straw bales blessed me at the end of the day with a little botanical happy pill in the form of newly sprouted bush beans that I had direct seeded less than 48 hours earlier.
If I were to do the straw bale garden over again, I might set some of the seedlings out earlier and cover them for the first couple of weeks. The one caveat I have for other would-be straw bale gardeners is that, while the claim that you can’t overwater them appears to be true, the reverse is also seems to hold. You do need to check the moisture around your plants as you do with any gardening method.
So far, however, my plants seem to be loving the heat and the decomposing bales, and, as mentioned previous post, you can still sit to do your gardening.
