Most Iochroma not tolerate frost and must be brought into their winter home early. This should be bright and about 5-15 degrees. Depending on the light intensity in winter quarters, the plant loses some of its leaves. The fertilizer will be set and maintained the substrate dry. But it should never dry out completely. the Cestrum can also overwinter dark. He then looses its leaves in the spring but new forms. If the bushes again move to the outside (mid-May) they should some day something shady thus are not burned.
