First, to choose the species. Suitable for spring sowing grass flowers are: Crosstalk, Amaranth, old and young, impatiens, string of red, aster, Scutellaria barbata, petunia, marigold, beautiful cherry and dill, morning glory and so on. Seeding before planting should pay attention to selection. Fresh, full of growth and development, grain full of seeds with high germination rate and germination potential; the same time, some of the seed coat thick, difficult to germinate varieties, such as morning glory, Impatiens, Amarantha, Soak in cold water or warm water for half a day (the water temperature does not exceed 40 ℃) so that the seeds fully absorb water swelling and dried after re-broadcast. Second, to get the law. Family sowing grass flowers, flowers can be used or shallow wooden box, filled with sand, soil (or sandy loam), compaction, scraping, watering can be carried out. Seeding should pay attention to spreading evenly, should not be too close. Larger seeds can be on demand, fine seeds can be mixed with the amount of fine sand broadcast. After sowing another layer of fine soil, not too deep, just to cover the seeds is appropriate. Third, to keep warm. After shaking should be properly insulated, sowing pot should be placed at a warmer place, and with glass or
