1、 Improper watering

Reason: camellia is resistant to drought and humidity. If too much watering causes soil ponding, Camellia will drop its bud, serious ponding and even rotten roots. However, the soil should not be too dry, otherwise the flower buds of Camellia will fall

Solution: insert a bamboo stick into the soil along the edge of the basin, pull it out and have a look at it at ordinary times. If you find that the bamboo stick turns white and the hair is dry, pour it into the water in time

2、 Nutrient deficiency

Reason: the pregnant bud period of camellia is very long. If the soil nutrient is insufficient, the camellia will lose its bud if it lacks nutrition. In addition, if there are too many flower buds on a branch, the camellia will also lose its bud if it feels that the nutrient supply is insufficient

Solution: when changing pots for camellia, apply sufficient slow-release fertilizer. During flower bud differentiation, topdressing once every half a month until flower buds form. When the flower buds grow to the size of soybean, the buds will be sparse, and 1-2 flower buds will be reserved for each branch

3、 Excessive fertilization

Reason: Camellia likes to apply thin fertilizer frequently. If excessive fertilization is applied, the plant will drop flower buds, and the plants with serious fertilizer damage will fall madly

Solution: when Camellia produces fertilizer damage, flush the basin soil with large water, flush out the excessive fertilizer water, dilute it and put it in a cool and ventilated place to slow down the basin

4、 Environmental change

Reason: after the camellia bud, if the plant is often moved to make the camellia adapt to the new environment, it is easy to drop the bud. Don't let the temperature of tea buds fall below 35 ℃, or the temperature of flowers will fall below 0 ℃

Solution: after the camellia sprouts, don't always move the plant. Keep the maintenance temperature above 0 ℃ and a relatively cool place to ensure sufficient water without ponding. Just bask in the sun in autumn and winter and wait for its flowering
