Most, if not all fruit trees (bare root or potted), comes grafted on root stock of a different variety/cultivar. My question is not why, as the positives are well known. However, I do wonder a couple of things about its role after planting.
I no longer have this issue since I learned to plant much higher, but in the past when planting bare root trees, I planted them somewhat close to the graft point. Over the course of the year, the plant hole settled causing the "hole" to cave in and as a result, soil in some cases now fully cover the graft point. The tree grows just fine, but has developed roots at the graft point and/or above it. So in other words, roots come from both the roots stock and the graft. What is the result of this? The root stock no longer provides the benefits? Will it grow/produce differently?
When taking cuttings from these trees, the resulting tree will be on its own without the benefit of the root stock. Is this a bad idea or not? I mean, a bare root cherry tree costs around $50. I have no desire to fill out my orchard with purchased trees every year and want to instead use the existing trees to do it for me by using cuttings. Sure it takes a bit longer, but it's free and I get the type of tree I want (minus the root stock). Or can I get the trees the root stock is based on for much cheaper and then do the graft myself?
