Key Points and Precautions for Osmanthus Maintenance in Autumn
Here we introduce the knowledge of osmanthus autumn maintenance, followed by detailed content sharing.
As one of China's top ten famous flowers, osmanthus is deeply loved by flower enthusiasts. Gardeners like to plant an osmanthus tree in their yards, and when the flowers bloom, the entire garden is filled with fragrance. Even those without gardens enjoy growing potted osmanthus plants at home.
Key Points and Precautions for Osmanthus Maintenance in Autumn
Whether planted in the ground or in a pot, if you want the osmanthus to be full of flowers in autumn, you must pay attention to the following points after the beginning of autumn, otherwise it's easy to drop flowers and leaves.
1. Avoid Overwatering
For ground-planted osmanthus, there's no need to water deliberately unless it's a dry season; they can grow well with natural rainwater. However, during the rainy season in autumn, it's important to ensure drainage for ground-planted osmanthus to avoid waterlogging which can cause flower buds to fall off.
Potted osmanthus, due to limited growing space, requires frequent watering. In summer, with hot weather and rapid evaporation, watering frequency is high. But as autumn sets in and temperatures gradually drop, evaporation isn't as quick. It's important to pay attention to the moisture changes in the potting soil, watering thoroughly when dry.
Continuing with the summer watering frequency can easily lead to waterlogging in the potting soil, causing the osmanthus to suffocate its roots and resulting in dropped flower buds and leaves. At the transition from summer to autumn, special attention should be given to the moisture changes in the potting soil, watering only when dry and then thoroughly.
2. Ensure Sufficient Light
Osmanthus loves sunlight and can be maintained in full sun even in summer. Many enthusiasts provide shade for potted osmanthus in summer, but as autumn arrives, it should be gradually transitioned to full sun.
Only with sufficient light can osmanthus photosynthesize effectively to produce nutrients, allowing flower buds to grow normally. Insufficient light for an extended period can lead to fewer flowers, delayed blooming, or even dropped flower buds that fail to open properly.
3. Apply Phosphorus and Potassium Fertilizer Promptly
After the start of autumn, it's a crucial period for the growth of osmanthus flower buds. Osmanthus requires ample phosphorus and potassium fertilizer to support the growth of a large number of flower buds. If fertilizer isn't applied for a long time, the osmanthus may drop flower buds due to insufficient nutrients.
To encourage abundant flowering in osmanthus, it's important to apply fertilizer promptly in autumn. It is recommended to use phosphorus and potassium fertilizers primarily. For ground-planted osmanthus, you can apply a solution of monopotassium phosphate every 10-15 days to promote flower bud growth.
For potted osmanthus, it is recommended to apply a solution of monopotassium phosphate every 5-7 days after the start of autumn, and foliar application can also be performed, spraying every 3 days. Since potted osmanthus has limited growing space, fertilizing should be frequent but light, avoiding heavy or raw fertilizers. While applying water-soluble fertilizers, it's also important to apply fermented organic fertilizer or slow-release fertilizer around the pot edges every 2-3 months, providing a continuous supply of nutrients for the osmanthus growth.
The introduction to the key points and precautions for osmanthus maintenance in autumn, and how to grow osmanthus well in autumn focuses on these three points, and this is the complete introduction shared in this article for everyone to learn and understand!
