Seed propagation Pelargonium very profitable in spite of the high cost of seeds, they have a high germination rate and give a large number of seedlings; from seed grow compact, beautiful bushes with an abundance of large caps flowers.
Pelargonium seeds from large, covered with dense leathery shell. From seeding before flowering takes 5-6 months. Sow seeds of Pelargonium can throughout the year in the presence of supplementary lighting in autumn and winter. Usually growers amateur vesevayut pelargonium from November to April. I prefer to plant pelargonium in February-March (at the time of emergence and top growth of seedlings increases the duration of daylight).
The soil for planting geraniums should be loose, moisture and breathable. To compile the substrate can be used peat moss, perlite, leaf and humus soil, sand. For sowing seeds Pelargonium experts recommend the following composition of the substrate: turf ground, sand and peat in a ratio of 2: 1: 1. Before sowing, it is desirable to disinfect the substrate (can shed its pink solution of potassium permanganate, sodium biofungicide "fitosporin-M"), as pelargonium seedlings susceptible "blackleg".
To speed up the germination of seeds collected Pelargonium experienced growers spend their scarification (triturated with fine sandpaper to remove the coating of scales and light violations coating shell). Prepared for planting the seeds germinate in 7-10 days, and without pre-processing of their germination is not unanimous and may take up to 3 months. Commercially available seeds, already peeled the cover scales, they germinate in 2-3 weeks.
Pelargonium hybrids F1, grown from seed, in the future can be propagated only vegetatively, as obtained from the seeds will produce splitting in subsequent generations (grown from these plants will not like the parent). Seeds formed on varietal Pelargonium under favorable growth conditions as a result of artificial pollination, insect pollination or self-pollination can be used for sowing. They are collected from plants in the summer or early fall, after browning bolls.
Pelargonium seeds sown in boxes and bowls filled with moist substrate, sprinkle a thin layer of sand or substrate thickness of 2-5 mm, sprayed on top after planting and cover glass bowl. Requires daily airing shoots rising glass and wiping it from condensation.
For seed germination is required to maintain the temperature of Pelargonium 18-22S В° and regularly moisten the substrate to dry out. Bowl with the emerging seedlings put on a bright place; when there is sufficient light seedling grows strong and stocky, is developing rapidly. After emergence, it is important to maintain a moderate soil moisture and prevent it from drying, protect the seedlings from direct sunlight, gently loosen the soil and aerate seedlings.
1-1.5 months, when the plants produced 2-3 real leaf, held swordplay seedlings pelargoniums in pots, it is important to plant at the same depth at which they grew before. Optimum temperature for growth 16-20S В°. For better tillering seedlings Pelargonium pinch of 5-6 leaves. Plenty of light and fresh air promotes good growth and continued flowering pelargonium.
