Spring, summer and autumn shading: calendula can not be exposed to strong light, spring, summer and autumn need to be shaded in time, if the temperature during the day exceeds 25 ℃, do not directly put in the sun, otherwise the leaves will obviously become smaller, the distance between the branches will be reduced, the leaves at the bottom will gradually turn yellow and fall off, and the growth of the plant will gradually slow down and even infiltrate semi-dormant state. In winter, because the temperature is not high, it can give direct light and promote photosynthesis, which is conducive to the formation of flower buds, flowering and fruiting of calendula. After the plant blossoms, the plant can be maintained indoors for 10 to 15 days, and then moved to the outdoor shade environment for one month, so alternate maintenance is conducive to the accumulation of plant nutrients and prolong the flowering period.

two。 To warm, avoid extreme heat: calendula likes warm climate, afraid of extreme heat, summer temperature higher than 34 ℃ will be poor growth; not resistant to frost, winter temperature below 4 ℃ will enter dormancy or even death. The most suitable growth temperature of marigold is 15-25 ℃.

3. Pruning: cut off the branches with old and yellow leaves every two months, as long as the temperature is right, it can blossom all the year round. Coring is usually carried out twice before flowering to promote the germination of more flowering branches: one to two weeks after potting, or when the seedling is 6-10 cm tall and has more than six leaves, remove the tip and retain the lower 3-4 leaves to promote branching. After 3-5 weeks of the first coring, or when the lateral branch grows to 6-8 cm long, the second coring is performed, that is, the top tip of the lateral branch is removed and the 4 leaves under the lateral branch are retained. After two coring, the plant type will be more ideal and the number of flowering will be more.

4. Control humidity, spray water in time: calendula likes humid environment, control humidity at 75-85%, spray water in time to increase humidity during maintenance, 1-3 times a day, high temperature in sunny days, appropriately increase the number of water spraying, lower temperature in cloudy and rainy days and reduce water spraying times appropriately. But excessive spray, heading is easy to be infected by bacteria and rot, so spray should also pay attention to the water quality.
