when is the best time to repot dwarf apple trees

Question

I have two dwarf apple trees in 12-inch wide by 11-inch tall pots. They are about 4 ft tall and in flower. Can I repot them now and what size pot should I use?

Answer 1

Assuming that you want to pot up, in other words put into a larger pot to promote growth, use a pot one size larger than the current one. From a 12″ pot go to a 14″ diameter.

The “when” to repot is a subject of debate. Some people say late winter – early spring, while the plant is still dormant; others say late spring – early summer, when the plant is heading into its period of greatest growth. The dormant period is recommended to avoid damaging roots, but I prefer the summer time, because bonsai growers have proven that cutting roots is not damaging to the plant, so that’s not really a factor.
