SUSINO RECINELLA Autofertile - 9FS11-

Some plum varieties are self-sterile and therefore bear no fruit or only very little fruit 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.

Planting Potted Plants
Potted fruit trees should be planted at the appropriate depth, so that the grafting point is not buried and the upper part of the root system is at ground level. Once the plants have been planted, it's a good idea to compact the soil around them, mixing it with an organic fertilizer to create a sort of basin. Wet the basin 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—that is, apricots, cherries, chestnuts, quinces, figs, apples, walnuts, pears, peaches, and plums—are: 4.50–5.00 m between plants along the rows, and 5.50–6.00 m between rows. These distances can be significantly reduced for apple, pear, and other dwarf fruit trees or those grafted onto less vigorous rootstocks.
Planting Periods
It is best to plant fruit trees in late autumn, that is, in the months of November and December (before the frost), although planting later in the winter is also possible if the ground is not frozen. Another good time for planting is February-March, or at the latest until mid-April. Only if the plants were previously grown in pots can planting be carried out in the following months, with due caution and keeping the root ball intact. Fruit trees grow well in well-fertile, deep, and permeable soil. If, however, the soil is very clayey and rather compact, it is advisable to provide deep drainage.
NB . The ripening times of all fruit plants can be early or late even by a week or more, depending on the exposure and the climate.
