Can you make an apple, plum, or lemon tree into a bonsai?

Answer 1

Yes. Any tree, plant, or vine can be made into a bonsai style. Preferrably you'll want small leaves and small fruit. The leaves, fruit, and flowers will be the same size when it is trained as a bonsai and it would be if the tree were planted in the ground. You may want to check the Bonsai Care page of my website:

Answer 2

Yes, to all of the above. If you go with apples, I'd go with crab apples; the fruit is smaller an has a better look for bonsai. Plum is a very traditional tree for bonsai purposes; that would be my choice, but why not try one of each? :-)

Answer 3

There is no reason why you couldn't make any tree into a bonsai providing you start early enough.

Answer 4

Yes.

Lemon may be the easiest of the three to work with.
