Why I don’t like a 4 foot grow boxes in a Mittleider garden
I’ll be honest here, I don’t like 4 foot wide grow boxes. They’re popular and you will see all kinds of articles and videos where they are recommended. They require too much bending over of the gardener for my liking. For a Mittleider garden I think they’re generally a mistake.
It is difficult to tend to stuff in it and you can’t reach from one side to the other. This becomes particularly evident when things are grown vertically. Reaching towards the middle of the box to prune or harvest from a mature plant is near impossible. Sure, you can push through and get it done but you risk damaging plants. you could even knock off nearly ripe vegetables.
The top of these tomatoes in the picture below are a little more than 3 feet apart. I can only prune and harvest easily by going down each side of my grow box. Growing these tomatoes in a 4 foot wide grow box would prevent the easy access necessary to properly care for our plants.
Are there good uses for 4 foot grow boxes?
There are indeed. First, if you’re on a very tight budget yet determined to have a grow box the wide grow boxes will work. For the cost of two 18 inch wide boxes you can build one 4 foot box. But if you’re on a budget I’d highly recommend growing in your own soil.
The only time I might recommend a 4 foot wide grow box in a Mittleider garden is for growing potatoes. We have heavy clay soil here in Missouri. Our grow box dedicated to growing potatoes allows them to sprawl and makes harvest a breeze. It is isolated from the rest of the garden and is used only for potatoes. In this picture below we grew sweet potatoes last year.
What size grow box do I prefer?
That’s easy. An 18 inch wide grow box is ideal, particularity for vertical crops in my Mittleider garden. We built these grow boxes in our in the garden green house.
