Camellia won't bloom normally? Analysis of the latest causes
Camellia is an evergreen shrub and small tree. Its flowers are delicate and beautiful, and it is the beloved favorite of many gardeners. However, if cared for improperly, it will fail to bloom, and you will not be able to appreciate its beauty. So why can't camellia bloom normally? Let's find out together.
1. Unsuitable temperature
Camellia prefers a warm and humid climate, and it grows poorly in both cold and hot regions. If the temperature suddenly drops below zero degrees, the young branches will be frostbitten, and the flower buds will also be affected and drop off. For potted camellias, their cold resistance is weaker than that of those planted in the ground, and they may freeze to death directly. If the temperature reaches above 35 degrees, it will cause flower buds to drop or fail. The most suitable growing temperature is 20-25 degrees.
2. Unsuitable soil
Camellia also has certain requirements for soil. For potting, it is suitable to choose slightly acidic, loose and fertile mountain soil or sandy loam. If the soil is too acidic or too alkaline, it will cause flower buds to drop, resulting in failure to bloom normally. Therefore, pay attention when preparing the growing medium. The normal pH value is between 5.5-6.
3. Insufficient water
Throughout its growth and development period, camellia has a relatively high demand for water. Insufficient water will cause flowers and buds to drop, and may even lead to the death of the entire plant. In addition, when watering, pay attention to water quality. Do not irrigate with water containing salt or alkali. It is best to catch rainwater in a container on rainy days and use it for watering when water is insufficient. You can also add 0.1% ferrous sulfate solution to tap water to change the water quality, promoting strong plant growth and deep green leaf color.
4. Overly frequent fertilizing
Camellia is not tolerant of fertilizer. When fertilizing, pay attention to the concentration. If the concentration is too high, it will also cause its root system to rot. Overly frequent fertilizing will lead to excessive growth of branches and leaves, leaving no opportunity for buds to form and bloom, so be sure to pay attention when fertilizing.
5. Pests and diseases
Pests and diseases can also cause camellia to fail to bloom normally. The main pests of camellia include bud stem borers and scale insects; the main diseases include anthracnose and sooty mold, and attention should be paid to prevention and control.
