Winter maintenance methods of potted osmanthus fragrans;

1, indoor movement

Osmanthus fragrans is a cold-tolerant plant, and it is good to breed in the south, but it must be moved to a warm greenhouse or put in a heated room in the cold north. Whether in the south or the north, the temperature shall not be lower than 0℃ during curing. Once it is too cold, put it in a warm place.

2. All-day sunshine

Plenty of light is very warm, and it will also play a certain anti-freezing role. Especially when the temperature is below 5℃, we must ensure sufficient sunshine, otherwise the slow growth of plants in the coming year will also affect flowering.

Step 3 reduce watering

Many flower friends don't know how to raise potted osmanthus in winter, so it is most important to reduce the amount of watering in winter. The frequency of watering can be maintained at 10 day. In order to avoid frostbite of plants due to watering, watering should be carried out at the warmest noon of the day, and watering should be avoided as much as possible in rainy and snowy weather, and drainage should be carried out in time to prevent root rot.

Step 4 stop fertilizing

Potted osmanthus does not need fertilization in winter. The winter climate is cold, and the plants themselves are already very fragile. Fertilization will only cause fertilizer damage and damage plants. It is best to apply a little diluted fertilizer to potted osmanthus when the weather is still warm in autumn, and nitrogen fertilizer is the best, so that there will be no fertilizer damage and the plants can safely overwinter.
