Feed Clethra barbinervis
Shrubs develop new shoots and prepare their flowers during the spring period, therefore we must remember, by the end of the winter, to give it a good dose of humus or mature manure, or granular slow release fertilizer, to be added to the soil at the foot of the plant. During the spring we can choose a fertilizer rich in nitrogen and potassium, to mix with the irrigating water, every 20-25 days.

These plants aren't evergreens, which means they lose their leaves some months during the year. These plants have a sapling deportment, with a short stem with a small roundish crown.
