Flowering and Fruit Bearing Tree Species

Описание: Azaleas (Rhododendron indicum) for example grow base dominant – in contrast to most other species. This means that the lower branches grow stronger than the apex, which should not be pruned too heavily. The flower buds form in summer for the following year, so you should trim your azalea immediately after flowering and then don't prune much more if you want flowers in the next year.
The Japanese flowering apricot (Prunus mume) flowers in late winter or early spring before the leaves emerge. You can shorten the branches after flowering, but you must identify the leave buds and make sure, there is at least one left at the end of the twig. If you cut a branch so short that there is no leaf bud left, the branch will most likely die. Also very significant is the Cherry blossom bonsai.
There are species which flower at the end of the new shoots, like the pomegranate, the bougainvillea, snow rose, potentilla, Chinese quince and the lagerstroemia for example. If you want the flowers to develop then don't trim the shoots until the tree has flowered.
Many tree species flower on short shoots of the previous years, like the crab apple, hawthorn, blackthorn, firethorn and flowering quince. You can shorten the long shoots but take care to leave the short shoots intact.
If your tree should flower too abundantly or bear a great number of fruit you should thin out the flowers and fruit in order to prevent the tree from getting weak. The flowers and fruit should be evenly distributed on the tree and of the same size. So take off flowers and fruit where too many are in one place and pluck the largest and smallest.
On flowering trees that don't bear fruit, take off all the flowers when most of them have wilted. Azaleas form seeds at the base of the flowers which should be removed along with the wilted flowers.
Most species are monoclinous but a few are dioecious, which means there are male and female trees and only the female ones will bear fruit. The Japanese winterberry (Ilex serrata) for example is a dioecious tree and the female trees will only bear their lovely red berries if the female flowers are pollinated. This means you need a male Japanese winterberry flowering at the same time and standing as close as possible to the female to ensure pollination. You can also use a thin brush to take the pollen from the male flowers to the female flowers.
Birds love to eat the Ilex berries as well as those of many other species, so keep in mind to protect the trees from birds if you want to enjoy the sight of the magnificent fruit on your Bonsai tree.
