How to treat the withered shoot disease of camellia

Camellia is also known as camellia. Camellias have varying degrees of red, purple, white, yellow flowers, and even color striped camellias, and flower branches can reach up to 4 meters. Today, I would like to introduce to you how to treat the withered shoot disease of camellia.

1. How to treat the withered shoot disease of camellia

After the onset of camellia shoot blight, 50% methyl topiramate 800 times solution or 50% thiram 800 times solution should be sprayed in time, and an appropriate amount of phosphorus and potassium fertilizer should be applied, and less nitrogen fertilizer should be applied. Spray new high-fat film to preserve fertilizer and soil moisture.

Second, the propagation mode of camellia.

1. Cuttage

The most suitable cutting time is in September, and it can also be in spring. Select the well-growing, semi-lignified branches, remove the basal leaves, retain the upper 3 leaves, cut them into an oblique mouth with a sharp knife, immediately soak the cut in 200-500ppm indolebutyric acid for 5-15 minutes, dry and insert it into a sand basin or vermiculite basin.

two。 Leaf cuttings

Leaf insertion is best carried out in the rainy season, take one-year-old leaves as leaf insertion material, too old is not easy to root, too young and easy to rot. Insert about 2 cm into the soil, press the soil after insertion, pour enough water, and then put it in a cool and ventilated place. Generally, it can take root in 3 months, and it can sprout and branch in the next spring.

3. High insertion

The thin branches that need to be trimmed are girdled in an appropriate position. The girdling length can be between 5-8 mm. The plastic film of appropriate size is bound, and the sterilized peat soil or rotten leaf soil is added into the film. After 7-10 days, the lower part of the plastic film is peeled again for 5-8 mm, which is called double-ring peeling and high insertion method.
