semi dwarf apple trees
I am planing on prepping a 120' row for apple trees in my home garden for spring planting if the ground ever dries out here.
I am looking at both semi dwarf disease resistant trees, and dwarf. I dont plan on spraying them for bugs. Can I keep semi dwarf trees pruned so they stay shorter for their lifetime so I can reach the tree from the ground? I know they will get about 15' tall, but I think I would prefer to keep them topped off to about 8-10' tall if possible.
I like dwarf because of the ease of pruning, therefore they will have a higher chance of being pruned over the years. I dont like the higher price of planting or the extra step of supporting them since roots dont have good anchorage. So, I dreamed up this idea to possibly put semi dwarfs in and keeping them pruned to a smaller more manageable size...Any thoughts on this idea? Will dwarf/semi dwarf/ standard trees cross pollinate with eachother?
