What to Do If Camellia Flowers Don't Bloom
Do you know about this? Here are some small experiences in plant cultivation for when camellia flowers don't bloom, let's follow the editor to see the specific content!
What to Do If Camellia Flowers Don't Bloom
Causes for camellia flowers not blooming include low temperature and overly acidic soil. It is necessary to improve ventilation, trim diseased and dead branches promptly, remove sick and dead leaves, and place the plant in a sunny southern balcony or windowsill for care. Additionally, when scale insects attack the leaves, they can be gently brushed off with a soft brush, and other insects can be controlled with drugs like omethoate or acarbose. When diseases occur, Bordeaux mixture or carbendazim solution can be used.
Reasons for Camellia Not Blooming
There are two manifestations of camellia not blooming: one is not seeing any flower buds, and the other is having flower buds but not blooming. The reasons for camellia not blooming are:
1. Low temperature: Sudden drops to below 0°C cause frost damage to the tender branches of camellia, and flower buds that freeze will fall off and not bloom.
2. Soil too acidic: Excessively acidic or alkaline soil pH levels can cause camellia not to bloom. The normal soil pH should be between 6-5.
3. Insufficient water: Camellia requires a lot of water throughout its growth process. If water is insufficient or ventilation is poor, it can easily cause flowers and buds to fall, leading to the whole plant wilting.
4. Over-fertilization: Frequent fertilization causes camellia to have three rapid growth spurts in a year, which prevents the plant from forming flower buds and blooming, resulting in only leaf growth without blooming.
5. Pests and diseases: The main pests of camellia are stem borers and scale insects, and the main diseases are (T-J) disease and sooty mold, which can all cause camellia not to bloom.
Methods to Handle Non-Blooming Camellia
1. Appropriate watering: To avoid overwatering, it's best to water camellia when the soil is dry and slightly moist.
2. Avoiding light colors: Camellia prefers warmth and should be placed in a sunny southern balcony or windowsill to receive adequate sunlight.
3. Maintaining ventilation: In a poorly ventilated environment, camellia not only easily breeds pests but can also cause leaf spot disease. It is necessary to improve ventilation for camellia, and also trim diseased and dead branches and remove sick and dead leaves promptly.
4. Frequent application of dilute fertilizer: Camellia likes fertilizer, and fertilization must follow the principle of applying thin fertilizer frequently. Do not apply concentrated fertilizer, and camellia should be top-dressed three times a year.
5. Paying attention to pest control: Camellia leaves are particularly susceptible to scale insect attacks. When scale insects attack the leaves, they can be gently brushed off with a soft brush, and other insects can be controlled by spraying with drugs like omethoate or acarbose.
6. Diseases: Common diseases of camellia include (T-J) and brown spot diseases, which can be controlled by spraying Bordeaux mixture or carbendazim solution according to the instructions on the camellia, pot, and potting soil.
Preventing Non-Blooming Camellia
1. Shading: When sunlight is too strong at noon, it is necessary to use a shading net to block some of the sunlight for camellia.
2. Water control: Watering should only be done when the soil is dry or the leaves are wilted, as this can promote flowering. Also, this method can be used when flower buds are present to prevent them from falling off.
3. Fertilizer control: Fertilize camellia regularly, preferably with organic fertilizer, and stop applying fertilizer by July or August.
4. Pests and diseases: Appropriate prevention and treatment are needed based on the specific pests and diseases affecting camellia.
