How to propagate Japanese maples
American Nurseryman 151(9): 14, 117-120
Japanese maple, Acer palmatum, has produced a number of mutations that have become firmly established in the horticultural world in their own right. Dark purple-colored forms, such as A. p. 'Bloodgood', types with serrated foliage, such as A. p. 'Dissectum', and pendulous forms have been selected, grown and appreciated for a long time. The standard method of propagating has been to graft these selected forms onto seedlings of the original A. palmatum. This method is quite satisfactory; excellent plants have been produced in this way. If seed has been taken from a vigorous growing form of A. palmatum, the resulting understocks tend to transmit their vigorous outgrowth to the grafted variety. With the greatly increased interest in plants of limited size for the small modern garden, A. palmatum and some of the grafted varieties can prove to be a little too vigorous.
