There are flowers that, once grown from seed, bloom in the garden from year to year. These plants are called perennials, and it's not difficult to grow them at home from seeds.
Growing from seed is a long-term, but often the only way for the gardener. Sowing seeds is the most cost-effective way to get the right amount of plants, especially if you need a lot of them. And in some cases, seeds and seedlings are the only way out, since the plant may not tolerate division, cuttings and even simple transplantation. Perennials can be planted all year round, but most are planted between March and May.
From March to April, delphiniums, loosestrife, decorative onions, catchment, cloves, gravilat, ash, evening primrose, doronicum, kentranthus, armeria are planted on seedlings. Bellflower seeds are sown superficially and kept in the light, armeria seeds require preliminary soaking in warm water for about 8 hours. Plates with crops are placed in opaque black bags and placed at a temperature closer to room temperature. A good substrate for crops can be a mixture of equal parts of leaf humus, sand and sod land. This mixture is not filled to the top with containers for seedlings. For disinfection, containers are spilled with a solution of potassium permanganate of bright pink color, and then a layer of calcined disinfected sand is poured on top. If the sand remains dry, watering can be repeated. After an hour or two, you can start sowing.
Furrows are pressed into the substrate with a ruler, 3-5 mm deep and at a distance of 3 cm from each other. Seeds are laid in the grooves, keeping a distance of 1 cm between them. Seeds are covered with sand flush with the soil level. For perennials, light most often inhibits germination, so the seedlings are placed in dense bags, unless otherwise specified. Germination will be slow and poor at a temperature of 20 ° C and above, so it is better to place the seedlings in conditions with a temperature of 13-16 ° C. Seedlings are usually shown in 10-15 days. The first days they need to be protected from direct sun.
From May to the second half of July, perennials are sown in open ground. As a rule, these are the ones to sprout their home, having previously carried out stratification. Particularly difficult to germinate plants, such as aconite, milkweed and hosts, may make sense to sow before winter. This can be done in late autumn until the first frost, and even if the seeds are in the hands in the midst of winter: you can plant them at home in separate containers, which are then buried in the snow as deep as possible.
