Culture methods and matters needing attention of Chrysanthemum morifolium

I. Culture methods

1. Soil

It is afraid of dry, afraid of stagnant water, and needs neutral or slightly sour soil. Can give it fertile, breathable, well-drained sand, preferably rich in humus.

2. Watering

Its leaves are big and thin and need enough water, but they can't be too wet, as long as the leaves keep growing normally. Usually, you have to wait until the soil is dry and then irrigate, about once every two or three days, and you can also sprinkle the leaves with water. The time of high temperature can increase the frequency of watering.

3. Light and temperature

It needs sunshine when it grows, and it should not be shaded by the sun, preferably 15 to 20 degrees. If it is higher than 20 degrees, it may only grow. If it is lower than 5 degrees, it will stop growing. Below zero degrees, it is likely to have frost injury. Although it likes warmth, but it can not accept high temperature, from time to time to turn the basin to prevent uneven light, so that the plant type will be correct. A certain amount of light is needed after the flowers have withered before the seeds can develop.

4. Fertilization

Should be given every 7-10 days to add cake fertilizer, the dose should be dilute, chemical fertilizer can also be used. When the bud grows, you can add potassium dihydrogen phosphate until the flower grows.

5. Insect pests

Its most common pests are aphids and red spiders, which can be sprayed with dimethoate if they cause serious disasters.

II. Points for attention

1. If it is a red spider, it is usually behind the leaves, and the aphids are usually at the top, so when spraying pesticides, spray more on the back of the leaves and the top of the flowers, and the leaves can be sprinkled appropriately.

2. don't sprinkle it directly on the leaves when you fatten it. If you get it, wash it. Don't fatten it during the blooming period. When you grow up, put it in a well-lit area, and you can watch it in the house after growing, but it takes at least four hours of light every day to make the flowers more colorful.
