GeneralitŠ°

Sowing is the most common method of plant multiplication. This reproduction technique takes the name of gamic multiplication, that is by means of seeds, and differs from agamic multiplication, consisting of other types of multiplication (including, for example, cutting, grafting, offshoot, etc.). The most important difference between these forms consists in the fact that while the plants obtained with gamic multiplication are usually very similar to the plant that generated the seeds, but they can also differ significantly from it, vice versa the subjects obtained by agamic way have identical characteristics. to that of the mother plant.


Sowing: Types of sowing

In order for sowing to obtain good results, it is necessary to have seeds of high germinability and endowed with great germination energy. By germinability we mean the property of germinating, which the seeds keep for more or less long. With the term germinative energy, however, we refer to the vigor with which the seed gives life to the new plant. It can happen, therefore, that a seed, although able to germinate, has little vigor, and this usually depends on the lack of freshness of the seed. Where possible, therefore, it will be preferable to plant seeds of the last season.

Sowing can be carried out outdoors or in boxes or bowls, depending on whether the species to be sown are rustic or delicate. Outdoor sowing is carried out in previously prepared flower beds. To this end, it will be good to dig up the soil, remove the weeds and add sand and garden soil.

Sowing in seedbeds, on the other hand, is carried out using suitable compost suitable for sowing. To obtain a balanced mixture, the following proportions are generally followed: 1 part of garden soil, 1 part of sand and 1 part of peat. On the bottom of the bowl or seedbed, draining material (e.g. shards, pebbles, gravel, etc.) must be placed.

Sowing depth. The seeding depth must be very limited. Smaller seeds should be scattered on the surface available. These seeds should not be covered, because the humidity could cause them to rot.

The larger seeds, on the other hand, must be covered with a layer of potting soil equal to their diameter. Moreover, some seeds can be planted even deeper (for example beans or peas can be planted at a depth equal to 3 times their diameter).

Tips. Sometimes, after sowing, it is advisable to roll the soil to make the seeds stick to the ground.

In order to allow a better homogeneity in the broadcast, the smaller seeds are usually mixed with sand.

The first spring sowings must be protected from the cold by covering the seedbeds with glass plates or with sheets of non-woven fabric. Protection can be eliminated when the seeds have germinated.

To water the compost, very fine sprinklers are used. If sowing takes place in boxes or bowls, the containers can be immersed until the soil has moistened.
