I’m often asked this question but there isn’t a straight forward answer. Small trees are often slow growing and it can take many years for them to reach their full potential.
I recommend that a stronger growing tree is planted, one which responds well to pruning. The tree will then reach its flowering or fruiting potential within a reasonable time; annual pruning will ensure it doesn’t grow too large. Ornamental hawthorns, flowering crabs and small growing rowans are ideal.
