I have nine stock troughs that I am using for raised vegetable beds and so far it has been going fairly well. Last year I filled the bottom half of the troughs with tree prunings and called it hugelkultur.
Hugelkultur is the practice of planting in soil heaped onto rotting wood to take advantage of the whole composting system that results. I mostly did it to save money. Filling stock troughs with container soil would have been horrifically expensive without some free filler. The tree prunings provided that.
I topped the troughs with soil, making sure to fill all the nooks and crannies. Or so I thought. I found out I didn’t pack it down enough after I lost a few sprouted peas to a sinkhole. One day they were cheerfully checking out their new digs and the next there was just a hole where they had been.
I peered down the hole for the poor little fellows, hoping to somehow to fish them out, but there was no sign of them. I think they made their way to the bottom of the trough. Maybe later in the year they will resurface with a crazy long root system and produce mega peas. Maybe I will have stumbled on a new growing method that provides unbelievable produce and harvests. Maybe. But I doubt it.
The top bit of the troughs dry out fairly fast, so I have been watering pretty much daily. Especially after seeding the carrots. Those tiny seeds and wispy seedlings can dry out so fast, but so far so good.
I planted peas along the back of several troughs and then planted root vegetables in front of them, thinking it would be a clever use of both trough and vertical space. It seems to be working great in the pea and beet trough as well as in the pea and carrot trough shown above.
The two pea and potato troughs are another story.
The peas started off gangbusters but the potatoes soon caught up and are now surpassing them. The peas are flailing about behind the potatoes trying to make their way up the trellis and not looking happy about it. I may try trimming some potato leaves and see if that gives them the jump they need to rise above the spuds.
I started some spaghetti squash from seed and transplanted some in a trough and some on a mound up bed on the ground and while all of them are craving more heat and looking stressed, the squash in the trough are doing better than the ones in the ground.
My eggplants, tomatoes, beans and peppers all seem to like life in the the trough as well. It makes sense for these heat lovers, since metal heats up and things are warmer higher off the ground. And if the hugelkultur is working, there should be some heat coming up off the decomposing tree branches below.
So far the cooler crops like cabbage, chard, lettuce, carrots, onions and peas (the peas not being smothered by potatoes or falling into sinkholes) all seem to be doing well, but no better than the ones in the ground. The real test will come as summer heats up.
I realize the look of the troughs aren’t for everyone, but they are long lasting, their height makes them easy to work in and they don’t require any carpentry skills to build, giving you pretty much an instant garden. So far they are working well. Touch wood. Or in this case, metal.
If any of you have been trough gardening for awhile and have some tips to share I’d love to hear them.
