RUBY COLUMNAR PLUM TREE - 9FS44-

Pollination
Some varieties of plum tree are self-sterile and therefore do not bear fruit or bear fruit poorly, unless cross-pollinated with a specific variety. Other varieties, however, are self-fertile and fruiting occurs regularly even if there is only one plum tree in the orchard. The ideal conditions for proper pollination are:

- take into account the prevailing wind in the case of anemophilous pollination (pollination by wind)

- in the case of entomophilous pollination (by pollinating insects), we recommend distances no greater than 20 meters

In turn, the pollinator needs the plant it has pollinated to bear fruit (except in cases where it is self-fertile).

Planting Potted Plants
Potted fruit trees should be planted at the right depth, so that the grafting point is not buried and the upper part of the root system is located at ground level. Once the plants have been planted, it is advisable to compact the soil around them by mixing it with an organic fertilizer, creating a sort of basin. Wet the latter with about 20 liters of water so that the soil adheres to the root ball without leaving air bubbles. The recommended planting distances for fruit trees, i.e., apricots, cherries, chestnuts, quinces, figs, apples, walnuts, pears, peaches, and plums, are: 4.50/5.00 m between plants along the rows, 5.50/6.00 m between rows. These distances can be significantly reduced in the case of apple and pear trees and other fruit trees that are dwarfed or grafted onto rootstocks of reduced vigor.
