The cold resistance is poor, and the suitable temperature for growth is 20-25 degrees Celsius. Stop growing below 15 degrees Celsius, and the leaves are withered and yellow and fall off below 10 degrees Celsius.

The planting effect of a string of red

In the summer high temperature and dry season, pay attention to shade cooling, often spray water, keep moist, about 15 days can be transplanted, is a relatively fast and relatively simple string of red breeding method.

2. Sowing and reproduction: in the south, it is usually the best time to sow seeds in a string of red open fields from late March to early April. The sandy soil with good drainage conditions and leeward is selected as the seedbed, the border surface is loosened, broken and leveled, and it is exposed to the sun for a few days. Then disinfect the seedling soil with potassium permanganate solution. Sow a bunch of red seeds on the seedbed, and then sprinkle the appropriate amount of carbofuran on the seedbed. Usually keep the seedbed moist, seedlings can emerge in 6-7 days under the condition of 16-21 ℃, and potted seedlings can be transplanted when 3-4 true leaves.
