Cause: too many flower buds lead to insufficient nutrients, which leads to short flowering period and easy to fall.
Solution: after the emergence of flower bud, it is necessary to pick the bud properly. For larger plants, less buds can be picked, and for small plants with poor growth, more buds can be picked. Generally, one bud is reserved for each branch, and all the others are removed. In addition, if the branches are thin and weak, the flower buds on them should also be removed, so as to avoid the waste of nutrients.
Reason: camellia is suitable to grow in acid soil, soil alkalescence will lead to poor development, and then lead to fall off after flowering.
Solution: to improve the pH of soil, ferrous sulfate can be mixed with water for irrigation. Generally, 0.5% ferrous sulfate can be added into the water when watering. Do not over water one time, but always water to keep the soil moist.
Cause: lack of water in flowering period, lack of enough water in plants, the flowers are easy to fall
Solution: if the flowers are thin and the soil is dry, most of them are under watered. In this case, the plants should be watered to ensure that the basin soil is wet. In addition, check the soil on time every day. If it is dry, water it in time.
Reason: nitrogen fertilizer will cause the plant to grow in vain, but also inhibit flowering, and more nitrogen fertilizer will lead to flower abscission.
Solution: take out the plant from the basin in time, clean the basin soil, and replace the basin soil.
