Avoid excessively sunny places; we suggest to put the the in a partially shady spot. When the minimum temperatures are very low we can protec the more sensible brushes by covering their roots with dry leaves or straw.These plants are rustic in the areas with a Mediterranean climate, therefore they can be grown outside.
Cultivation Clethra delavayi
The Clethra delavayi grows erect, developing a short stem with a small crown, usually roundish. This plant in the summer assumes a white colouring; it is large in size and can reach 5 m high. It doesn't keep its leaves in the winter. These plants are shrubs.
Fertilize Clethra delavayi
To obtain a florid development it is important to remember to fertilize our shrubs periodically; in the spring let’s use a fertilizer rich in nitrogen and potassium, which will favour the development of new vegetation and of flowerings. We can intervene at the end of the winter, mixing a good dose of slow release organic fertilizer to the soil surrounding our plant. During the spring it is also possible to act periodically, with liquid or powder fertilizers, to add to the water when irrigating, every 20-25 days.
Water Clethra delavayi
Water regularly, every 2-3 weeks , wetting the soil deeply with about 1-2 buckets of water ,but waiting for the substratum to dry completely between one watering and another; avoid leaving stagnant water. If we decide to grow a specimen of the Clethra delavayi in a container, we should remember that it will have slightly different needs compared to a specimen grown in the ground: we should pay more attention to its water and nutritional needs and check more often for possible development of parassites.
Pests Clethra delavayi
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there aren’t flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.
Mold Clethra delavayi
The Clethra delavayi prefers quite drained soils, with a low PH.
