What is the minimum / maximum distance apple trees should be apart for pollination? Got 2apple trees to plant. A 3yr Laxton superb that is gonna grow freely - just pruned annually for height restriction, and a 4yr Sunset to be trained as a cordon. I hope to restrict roots spreading vigorously.
Also - Is it true that patio paths at the sides will force the roots to go deeper as opposed to spreading out as much. Don't want roots to take all soil goodness from other veg if i can help it.
