What to do if hibiscus buds fall off

The buds fall because the soil is not suitable

Hibiscus likes loose, breathable, slightly acidic soil. If the soil is hardened and alkaline, it will make the hibiscus very uncomfortable and naturally unable to grow normally. At this time, even if there are flower buds, they will soon fall off. At this time, you can look at your flower soil to see if it is loose and breathable, and measure the pH. If it is alkaline, you can consider using ferrous sulfate or high-quality rice vinegar to adjust the pH.

Improper watering

Hibiscus likes slightly moist soil, so you should pay attention to watering it regularly, especially now when the temperature is high and the evaporation is large. But be careful not to water it too much or accumulate water, otherwise the flower buds will fall and the leaves will turn yellow.

Improper fertilization

Hibiscus flowers need to be fertilized properly, not too much or too concentrated, so as not to cause fertilizer damage, fertilizer damage to the roots, the flower buds will naturally fall, so the fertilization should be nutritionally balanced, not too much nitrogen fertilizer, otherwise it will make the hibiscus grow too long, not bloom, or not keep blooming. It is recommended to use some thin organic fertilizers and farmyard manure at ordinary times, and some phosphorus and potassium fertilizers during the flowering period, so as to apply thin fertilizers frequently.

Is it suitable to plant potted hibiscus individually or in multiples?

Hibiscus is a shrubby woody plant that can grow very large, so it is generally not recommended to plant several in one pot. In an ordinary flowerpot, one tree can grow into a very large pot. If you plant several trees, they will directly compete with each other. Not only will the branches intersect with each other to compete for sunlight, but the roots will also intertwine with each other to compete for water and fertilizer. Therefore, it is generally recommended to only plant one tree in a flowerpot.
