1、 Too many buds
Reason: too many flower buds lead to insufficient nutrients, which leads to short flowering period and easy to fall after flowering p>
Solution: pick the buds properly after the buds appear. Less buds can be picked for larger plants, and more buds should be picked for small plants with poor growth. Generally, one bud is reserved for each branch, and all the others are removed. In addition, if the branches are thin, the flower buds on them should also be removed, so as to avoid the waste of nutrients p>
2、 Soil alkalization
Reason: camellia is suitable to grow in acidic soil. Alkaline soil will lead to poor development and then fall off after flowering p>
Solution: improve the acidity and alkalinity of soil, and water with ferrous sulfate. Generally, 0.5% ferrous sulfate can be added during watering. Do not water too much at a time, but water frequently to keep the soil moist p>
3、 Insufficient watering
Reason: insufficient watering during flowering, the plant does not have enough water, and the flowers are naturally easy to fall p>
Solution: if the flower shape is thin and the soil is dry, it is mostly insufficient watering. In this case, the plants should be watered to ensure that the basin soil is wet up and down. In addition, check the soil on time every day. If it is dry, water it in time p>
4、 Excessive nitrogen fertilizer
Reason: nitrogen fertilizer will lead to plant overgrowth and inhibit flowering, while more nitrogen fertilizer at flowering stage will lead to flower abscission p>
Solution: take out the plants from the basin in time, wash the basin soil, and it is best to replace the basin soil p>
