How to propagate petunia?
Valuable varieties of plants difficult to propagate by seed: germination of them is only 60-65%, and with the purchase of a bag of seeds rarely get enough seedlings. Terry varieties and hybrids varietal groups practically do not form seeds, and gardeners each year have to spend money to buy the planting material in nurseries.
To avoid this, you can use the technique of vegetative propagation, which is used in greenhouses in the production of seedlings for sale. Cuttings of petunia performed easily even at home, t. To. The parts of the bush quickly produce roots and without the use of growth promoters.
Uterine bushes, from which the cuttings will be taken, could serve as a varietal plant that liked Last season, seedlings grown from seed on their own, or bought in the store with a copy flowers. Adult plant you want to save:
- in the second half of August, dig with a lump of soil and transplanted desired bushes in pots 15-17 cm in width;
- cut sprouts 1/2, leaving part of the leaves;
- transfer container into a room with a temperature of +10... + 12 ° C and kept at constant temperature.

Seedlings were grown and purchased items to form shoots length of 6-7 cm and then subjected to the formation of bush. Trimmed branches and serve as cuttings.

The substrate for rooting should be loose, but it is good to retain moisture. For this purpose, peat litter, mixing it with garden soil. The potting soil, you can add small beads perlite to absorb moisture they expended gradually. Primer dispersed on the pot to 100-150 ml capacity and good moisturize it. Containers are placed in a box with high sides and begin to prepare the cuttings:
- cut regrown lateral shoots (5-7 cm) from the mother liquor, or already prischipnut 1 times seedlings;
- remove the growing point and buds at the apex;
- break lower leaves half the length of the cutting, the lower section Kornevinom pollinate or other growth stimulant.
Prepared sapling stick to the substrate to a level undeleted leaves and continue with the following shoots. At the end of water the soil again to seal and cover the total box film or glass. Mini-greenhouse is not necessary to put on a bright sun, enough ambient light in the window and an average temperature of + 25 ° C.
Not to provoke fungal diseases, briefly lift the cover 1-2 times a day, airing landing. In the film the roof can make 2-3 small holes.
Rooting lasts for 15-20 days. By this time, the cuttings will be signs of growth: start growing side shoots from the buds at the base of the leaves left. When this happens, the film can be removed. Petunias in pots transplant is possible, when the roots fill the entire small capacity.
