Four-season camellia 1 soil cultivation methods and matters needing attention
Camellia has high requirements for soil in four seasons and likes to grow in acidic soil rich in humus. For our potted plants, five parts of soil, four parts of edible fungus residue and one part of cake fertilizer powder can be mixed and prepared.
2. Lighting equipment
Camellia likes to grow in a sunny environment all the year round, so pay attention to avoid strong light. Spring and autumn can be placed in a well-lit position. In summer, because the light is too strong, you can move to a ventilated room for shade. Keep the outdoor sunshine in winter to make it grow healthily.
3. Temperature
Camellia in the four seasons requires high temperature, so it is forbidden to be hot and cold. The optimum growth temperature is 18-25℃. Note that if the temperature is lower than 0℃, plants will be frostbitten and flower buds will fall off easily. If the temperature is too high, the leaves will turn yellow and fall off, which is not conducive to plant growth.
water
Camellia is a water-loving plant in four seasons. In the spring and autumn of the growing season, water often, about once every 2-3 days. Water once in the morning and once in the evening in summer, and spray wet water on or around the leaves to keep the soil moist. Enter the dormant period in winter, water less and pay attention to avoid water accumulation.
5, fertilization
Camellia is a fat-loving plant in all seasons, so be careful not to be too fat or too fat. Generally, it can be fertilized three times in the second half of flowering period, and the compound organic fertilizer is generally a mixture of phosphorus and potassium fertilizer. In winter, you only need to apply fertilizer once, so you can apply more phosphorus and potassium fertilizer to promote the delicious and beautiful flowers.
prune
When the four seasons camellias grow to a certain stage, it is necessary to do a good job of restoration. First, some diseased branches, dead branches and weak branches can be pruned to make them absorb nutrients more fully. After flowering, the dense buds can be cleaned up to keep the plants growing vigorously.
Step 7 change the pot
Generally speaking, the cultivation of camellia in four seasons should be changed every two years. It's best to do it in spring. When changing pots, you don't need to change all the new soil, just add a proper amount of old soil and new soil, add a small amount of base fertilizer, and finally water it.
8, pests and diseases
Anthracnose, soot disease and leaf blight are easy to occur in four seasons camellia, which can be sprayed with 600 times aqueous solution of 65% zineb wettable powder or 500 times aqueous solution of 50% Tobuzin wettable powder. Insects include scale insects and rust ticks, which can be sprayed with omethoate 1000 times solution or chlorothalonil.
