Can be sown directly into soil or containers. The seedlings (seedlings) obtained in boxes or pots are planted in a permanent place after quilting.Seeds need water, air and heat to germinate.The substrate must be moist, not too compacted, and the ambient temperature should be between 20-30 ° C.
To germinate, some species need light (dragonfly, begonia), while others need darkness (garlic, delphinium, black seed).It is worth collecting seeds of garlic, garden delphinium, sunflower, black cumin, poppy, nasturtium, violets, marigolds, primroses, cosmos, large-headed cornflower.
Plant division and layers
Dividing the mother plant is one of the easiest vegetative reproductive techniques. This method produces several smaller plants and rejuvenates the parent specimen.It consists in taking the plant out of the ground and dividing it into smaller fragments with their own roots.It is perfect for species forming clumps, suckers, rhizomes and stolons, e.g. sage, thyme, lily of the valley.
Layout is another natural reproductive method that you can use in your own garden.Stems that are part of the mother plant are covered with soil.The rooted fragment is cut off and cultivated separately. To aid root formation, a stem that is in contact with the ground can be incised, pinched with wire, twisted or a narrow ring of bark removed.
Nutrient restriction and hormone accumulation stimulate root production.There are different types of deposits.One time the shoot bends to the ground (simple, natural, apical, multiple), another time the soil is scooped up on the shoot (French, mounding, horizontal), and another time the substrate is placed on the plant (air dumps).You can reproduce magnolias, rhododendrons, blackberries, boxwood, witch hazel, clematis, spring ficus, lilacs, ivy, hydrangeas using the deposition method.
Planting and budding for a starter
Planting is the most common method of vegetative reproduction.Seedlings are made of fragments of shoots, leaves of some species and viable roots. With the support of hormones, adventitious roots are formed from the wound tissue.
Their development can be stimulated with the help of the so-called rooting plants that contain concentrated synthetic plant hormonesIn spring, herbaceous cuttings are harvested from young shoots or new, fully developed shoots of the parent plant. It is a good method of reproduction of hard-to-root species, but the cuttings require careful care so they do not wither.
At the end of summer, semi-woody cuttings are harvested. They do not lose water as quickly, but the root formation process takes longer. Woody cuttings are harvested from autumn to spring. They take longer to rooting than previous types, but they are the easiest to care for.These can be leafless seedlings of shedding deciduous species or leafless seedlings of evergreen plants.
There are several methods of joining plants: budding with a starter or T-shaped, grafting flat, by application, by use with a tongue, in a slot or in a saddle, and with a starter.The date of the treatment depends on the chosen technique.It can be performed in the spring, at the beginning of vegetation or in September, when the juices stop circulating.
High summer is not suitable as the grafting site dries up easily and the plants do not fuse together.Cutting knives must be sharp and clean. Thanks to this, the cuts will be even and easier to fit together. The vaccination site is tied with a flexible plastic band.
Once the scion is established, you can cut the rootstock above the vaccination site.It happens that the rootstock produces new shoots from the buds below the grafting site or through the root suckers.They must be removed because they are stronger than the inoculated scion and can lead to its death. Grafting is mainly used for the propagation of fruit and ornamental trees and shrubs.
