How to Care for Potted Osmanthus
The editor will answer your questions about how to care for potted osmanthus. Let's dive into the details together.
How to Care for Potted Osmanthus
Potted osmanthus thrives in loose, breathable, well-draining, and fertile slightly acidic soil. During the maintenance period, it should be placed in direct sunlight to promote bud differentiation. Osmanthus requires a lot of water, so it should be watered frequently. In spring and autumn, apply a dilute fertilizer every half month and combine it with superphosphate to promote rapid blooming.
Methods for Growing Potted Osmanthus
1. Slightly Acidic Soil
Before planting potted osmanthus, choose the right soil. Since osmanthus prefers to grow in loose, breathable, well-draining, and fertile slightly acidic soil, a mixture of sandy loam and peat soil can be used, or garden soil and river sand can be mixed.
2. Adequate Sunlight
Potted osmanthus is a sun-loving plant, so it should be placed in direct sunlight to promote bud differentiation. For young plants, some scattered light is sufficient. In summer, when sunlight is intense, avoid direct exposure and place it in a well-ventilated semi-shaded area.
3. Proper Watering
Osmanthus requires a lot of water, so it should be watered frequently. During the growing season in spring and autumn, water every 2-4 days. In summer, when temperatures are high and water evaporates quickly, water twice a day, early morning and late evening. If the air is dry, spray water around it and on the leaves. In winter, water once a week.
4. Reasonable Fertilization
Osmanthus does not require much fertilizer, but to ensure better growth and fragrance, apply organic fertilizer regularly. In spring and autumn, apply a dilute cake fertilizer every 15 days, combined with superphosphate to promote rapid blooming. Be careful not to apply too much fertilizer each time, and avoid getting it on the leaves.
Osmanthus Maintenance Precautions
1. The water management of potted osmanthus is challenging. Overwatering can cause leggy growth or root rot, so do not water excessively during daily maintenance. Even during the flowering period, avoid waterlogging.
2. Potted osmanthus grows rapidly and should be repotted every 1-2 years. Long-term failure to repot can lead to insufficient nutrients, making it difficult for the roots to spread and affecting flowering. When repotting, add a small amount of hoof slices as a base fertilizer and apply phosphorus and potassium fertilizers during the growing season.
3. If potted osmanthus is moved indoors during winter, it needs a low-temperature environment to enter a natural dormant period. If the ambient temperature is too high, osmanthus will not get enough rest, leading to the growth of new leaves, which consumes more nutrients. After moving it outdoors in spring, it may wither and die in dry winds.
4. Potted osmanthus is not resistant to smoke and dust. Growing in poor air quality can lead to poor growth, smaller and yellowing leaves, reduced or no flowering. Therefore, avoid pollution from smoke and dust during cultivation.
5. Common diseases of osmanthus include leaf spot, sooty mold, algal spot, root rot, and iron deficiency, while common pests include leaf miners, whiteflies, mites, longwhite scale insects, and yellow刺蛾. Treat these promptly with pesticides. Diseases can be controlled with Bordeaux mixture or carbendazim, and pests can be sprayed with dimethoate or fenvalerate.
