So last year I started several Apple trees from seed and they are currently doing well in 1.5 gallon garden pots. I would like to keep them in some kind of planters for the next 3-5 years as we will be moving around that point and I want to take them with me. They would be planted in the ground at that point. As they are growing on standard rootstock, how can I accomplish this?
I have access to 55gal. plastic barrels. If I was to cut them in half, drill a lot of holes in the bottom, place landscape cloth over the holes and fill with usual potting mix; how long could they grow in that? I could even bury those 1/2 barrels to ground soil height to simulate the natural growing environment. Thought?
