What should I do if the hibiscus buds fall off before they bloom?

1. Increase the temperature

Reason: Hibiscus prefers warm climate and cannot tolerate low temperatures. If the ambient temperature is lower than 5℃, it will affect its growth and cause the flower buds to fall.

Solution: Place the hibiscus in a warmer location. Since its flowering period is in autumn, the temperature may drop due to rainy weather. If the room temperature is not high at this time, you can put a plastic bag on the top of the plant to keep it warm.

2. Water more

Reason: Hibiscus is very afraid of drought. Once it lacks water, it will grow poorly and cause the flower buds to fall off.

Solution: Rehydrate the hibiscus flowers in time. Be sure to water enough, and don't water halfway, which will result in the roots not being able to absorb water. It is relatively moisture-resistant, so the potting soil can be kept moist for a long time. Once the surface soil is dry, you can water it. If you are worried that you will forget to water the plant, you can cover the soil in the pot with straw to keep it moist.

3. Enhance lighting

Reason: Hibiscus cannot grow without sufficient light. Keeping it in the shade for a long time will slow down its growth, affect the differentiation of flower buds, and cause buds to fall off during the bud formation period.

Solution: Make sure the hibiscus has plenty of light in the fall. If it is cloudy for a long time, you can use plant light to increase the lighting. You can also place it outdoors and let it receive sunlight for as long as possible.

4. Fertilization and bud thinning

Reason: Plants need to consume a lot of nutrients to bloom. If the nutrient supply is insufficient, the flower buds will fall off.

Solution: Timely addition of phosphorus fertilizer to hibiscus can promote its flowering. If there are too many flower buds, the nutrients in the soil cannot support so many flowers, and proper bud thinning is needed. Keep two flower buds on thick branches, one on thin branches, and remove all weak branches. In order to make the flowers bloom beautifully, the buds should be distributed evenly.
