Potted morning glory can be evenly mixed with half of the culture soil and plain sand into the No.1 tube basin in early April, and 4-5 seeds can be planted in each basin after sufficient water is poured. Then cover with glass to keep warm and moisturize, and germinate at room temperature of 25℃ for about 7 days. When the cotyledons are flattened, the seedlings can be transplanted and scooped out as a whole, and the seedlings are separated by soil. Then the lower end of the taproot was removed by 65,438+0 cm, transplanted into the first trumpet pot, and cultivated with culture soil. When the seedlings grow 6-7 leaves and start to spread, they can be dug out and planted in a larger flowerpot. Pot soil should be fertilized with cultivated soil, and the bottom of the pot should be padded with 2 cm sieve residue as drainage layer, and then a layer of soil should be filled on it, and 50 g horseshoe slices should be put as base fertilizer. After planting, water it. After the basin soil is settled, a thin bamboo pole with a length of 1 m is directly inserted into the center of the basin soil, and then a lead wire with a length of about 3 meters is wound around the bamboo pole at one end from the surface of the basin soil, and then the basin is wound upwards to form a tower-shaped hovering frame with a big bottom and a small top. Morning glory is a levorotatory plant, and the winding direction of the lead must conform to its growth habit. When the main vine climbs to the top of the pole along the lead wire, it will pick up the core. When the lateral vine grows 6-7 leaves, it will make the flowers bigger and bloom more.

If potted plants don't let it climb vines, when the seedlings grow to 5-6 leaves, transplant them into a tube basin, then pick the heart, promote the growth of 2-3 strong lateral buds, and wipe off the rest. When the lateral buds stretch the vines, leave 2 ~ 3 leaves to remove the tips, so that they can bloom for about 10 days at a time. After the flowers wither, pick them in time to promote their lateral branches to germinate again, leave a few, wipe off the excess, and still pick the heart according to the previous method. In this way, the plant shape can be kept full, clustered and blooming continuously.
