1. How does hibiscus get through winter?
Generally, hibiscus planted in the ground in the south can overwinter naturally, but hibiscus in the north can only be grown in pots and moved indoors for care. The room temperature is best kept at 8-18°C, and watering should be stopped at the same time so it can get through winter safely.
2. How is hibiscus cared for?
1. Soil
Choose weakly acidic soil that is fertile, loose and well-drained. In addition, the time to repot hibiscus is in late spring and early summer when it is moved out.
2. Light
At the beginning of May, it is best to move the potted hibiscus outdoors to grow it; the daily light for hibiscus is best controlled at 8 hours.
3. Temperature
The best growing temperature for hibiscus is between 15-25°C; during this period it grows especially fast and also blooms easily.. In summer, lower its temperature, and in winter remember to keep it warm, otherwise it is still very easy to freeze and be damaged.
4. Watering
Hibiscus does not need too much watering; generally in spring and autumn once a week is enough, in summer watering once every 3 days is fine, and in winter water as little as possible, once every 10 days is no problem, and when there is extremely cold weather, stop watering.
5. Fertilizing
Hibiscus does not have high fertilizer requirements; generally applying some compound fertilizer is enough, and in spring and autumn some phosphorus fertilizer can be applied to promote flowering.
6. Pruning
Hibiscus also needs proper pruning of its branches; when spring has just arrived, hibiscus should be pruned once. Apart from keeping 3 buds on the base, all the parts above should be cut off; pruning helps hibiscus grow new branches.
If you want hibiscus to get through winter safely, keeping it warm and controlling water are very important; friends who grow hibiscus should remember this well.
