As one or two-year-old cultivated plants in China, melon leaf chrysanthemum is very popular among flower friends because of its rich color and simple cultivation. In daily maintenance, what should be paid attention to? Let's go and have a look!
The main points of the conservation of chrysanthemum are as follows: 1. Water: keep the pot soil slightly moist, and water thoroughly. But avoid poor drainage.
2. Fertilizer: apply thin fertilizer during the growth period, and pay attention not to make the fertilizer splash on the leaf surface. After fertilization, wash it in time and spray new fat film to keep the fertilizer and moisture. Fertilization should be stopped during flowering.
3. Soil: general soil.
4. Temperature: avoid hot, the suitable temperature for growth is 10-20 ℃, the temperature can be further reduced during the flowering period, so as to prolong the flowering period, and the seedlings can withstand the low temperature of 1 ℃.
5. Light: during the growing period, it should be put in the greenhouse with better light, and after flowering, it should be moved indoors for appreciation. It should be put in front of the bright south, West and East windows for at least 4 hours of light every day, so as to keep the flowers colorful and the plants robust. Spraying huahuazhuangdiling at the flower bud stage can make the flower bud strong, the petal big, the flower color bright, the flower fragrance strong and the flower period prolonged. In the cultivation, we should pay attention to changing the direction of the pot to make the corolla shape regular.
6. Propagation: seed propagation. The suitable temperature for germination should be 20-25 ℃, and the seedlings should emerge in 10-20 days. Depending on the growth of the seedlings, the pots of corresponding sizes should be used gradually.

7. Pay attention to humidity control in winter: the humidity requirement of chrysanthemum is relatively high, in order to grow well. How to make the humidity moderate in winter is the key to the success of cultivation. Too dry, easy to make the leaves of Chrysanthemum in wilting state, not conducive to leaf growth, easy to make the leaves yellow, also easy to produce red spider and aphid. Too much watering and too high indoor humidity can easily rot the roots, main stems and leaves, and produce aphids; if the room temperature is too high and the ventilation is not good, powdery mildew can easily occur.
8. Control aphids and red spiders: the first is to maintain appropriate temperature and humidity, maintain good ventilation. Secondly, in the early stage of the disease, it is necessary to find out in time, separate the damaged plants as soon as possible, and spray a small amount of pesticides on the damaged plants. For aphids and spider mites, 2000 times dimethoate dilution can be used. Because red spider usually occurs on the back of leaves, and aphids usually occur on the top of young leaves, spraying should focus on the back of leaves and the top of plants, and spraying should be appropriate on the front of leaves.
