How to care for osmanthus in summer? Follow strictly, no yellow leaves, fragrant flowers in autumn.
Osmanthus, as one of the top ten traditional famous flowers in China, is deeply loved by many flower enthusiasts. If you enjoy the fragrance of osmanthus, it is recommended to plant August osmanthus, which has the strongest scent. Although the fragrance of osmanthus is pleasant, it is prone to yellow leaves, especially in summer. Poor management can lead to yellow leaves and fewer or no flowers in autumn.
Key points of osmanthus management in summer
For summer management of osmanthus, we can focus on the following four points.
1. Provide proper shading for potted osmanthus
Osmanthus loves plenty of sunlight, but during high-temperature periods in summer, potted osmanthus should be shaded appropriately to avoid direct exposure.
In a sun-exposed environment, the fibrous roots of potted osmanthus can easily get scorched, leading to weakened growth and susceptibility to diseases and pests.
Moreover, high temperatures combined with direct sunlight can cause rapid evaporation of water, leading to dry soil and drought stress for the osmanthus.
2. Watering for ground-planted osmanthus
Compared to potted osmanthus, ground-planted osmanthus is more resistant to sunlight. Although it does not need to be shaded in summer, it is important to water it regularly to avoid drought.
Ground-planted osmanthus should be watered immediately when the soil surface is dry, keeping the soil slightly moist, which is beneficial for the growth of osmanthus.
However, for potted osmanthus, watering should be more careful. The principle of watering is to water thoroughly only when the soil is completely dry, and never overwater, as this can cause waterlogging. Especially in hot and humid regions in summer, special attention should be paid to watering. It is best not to let it rain, and if it does rain for a long time, ensure that the pot does not accumulate water. After the rain stops, promptly apply hymexazol to the roots to prevent root rot.
3. Moderate fertilization
How to care for osmanthus in summer?
In high summer temperatures, it is recommended to stop using fast-acting liquid fertilizer for potted osmanthus, as it can easily cause fertilizer damage. Instead, use some fermented organic fertilizer or controlled-release fertilizer, which provides a slower and more sustained nutrient supply, making it safer.
After the beginning of autumn, you can apply some bone meal to osmanthus to supplement phosphorus and potassium fertilizers, promoting bud growth.
4. Preventing diseases and pests
Osmanthus is easily affected by leaf blight, causing yellowing and withering of the leaf tips, symptoms similar to fertilizer damage, which many flower enthusiasts often mistake for fertilizer damage.
Leaf blight should be prevented first. Starting in May every year, you can spray carbendazim every半个月 to prevent it. When leaf blight occurs, promptly spray mancozeb to easily treat it.
Besides leaf blight, red spider mites often infest osmanthus, especially potted osmanthus. It is recommended to place them in a well-ventilated area rather than in a corner. When watering, also rinse the leaves. Outdoor ground-planted roses are relatively robust and less likely to be infected by red spider mites. Regular prevention of leaf blight is sufficient.
