Question: hibiscus

This summer I planted a blue hibiscus in a sunny part of the garden, despite the smallness of the plant in August the first two or three flowers have already sprung up. Although I fertilize the plant every two weeks with ox blood, I noticed that from the first days of November the seedling drops small yellow and dry leaves. What does this mean? Do I have to cover the plant already? How is the hibiscus protected during autumn and especially in winter? Many thanks for the reply.


Answer: hibiscus

Dear Simona,

with the shortening of the days and the decrease in the night minimums, the plants naturally prepare for the winter vegetative rest. In general, it is advisable to suspend fertilization already in September, to avoid enriching the soil with mineral salts that the plant does not need at this time of year, and which will be washed away by the rains before the arrival of spring.

In general, the deciduous hibiscus spends the winter in complete vegetative rest, and can easily withstand even very rigid temperatures, many degrees below zero. So it does not require winter cover in most of Italy.
