After the Ching Ming period, weeds are stalked bark, marigold, zinnia, amaranth, cockscomb, impatiens, bell pepper, a bunch of red, violet jasmine, beautiful cherry, petunia and so on. Grass flower method, there are two types of garden broadcast and pot seeding. When the grass is planted in the garden, it is necessary to loosen the land first, and the depth is preferably 20 to 30 centimeters. Pick the bricks and stones, level the soil surface, open the ditch or dig a hole. Then fill the water until all the water has penetrated into the soil. Such as small flowers, like cockscomb, beautiful cherry seeds can be mixed with fine soil surface into the ditch, large seed can choose 2 to 3 seeds into the hole, and then cover the soil. When the seeds germinate, 2 to 3 true leaves must be seedlings to avoid overcrowding and poor growth. Small seedlings can also be transplanted into flower pots. It is best to use plain sand in pots, soak the seeds evenly on the soil. The thickness of the cover soil is suitable to just not see the seeds. The surface of the bowl must be covered with glass or plastic film to keep it moist. When the basin soil is dry, the basin should be placed in a large basin filled with water to soak the water, and water can not be sprayed directly in the basin to prevent the seeds from being washed and moved to affect the germination. Place the pot in the shade and the seeds germinate before moving to the sunny place. When two to three leaves are to be grown, it is possible to plant seedlings. At this time, the plain sand in the basin should be replaced with sandy loam. General grass flowers can be gradually blossomed after entering June, and some grass flower varieties can be opened until autumn season, adding beauty to the courtyard and balcony.
