The Petrocosmea kerrii is grown at home or in a warmed green house; during the Spring it can be moved outside, but only if the mimimum temperatures are clearly mild. Usually during the coldest periods of the year the aerial part of these plants dries; it will begin to develop again the spring after.Locate the the Petrocosmea kerrii in a partially shaded place, so that it is protected by direct solar rays.

Feed Petrocosmea kerrii
In the spring let’s remember to fertilize our perennial plants, using a slow release granular fertilizer, to add in one solution every 3-4 months. If desired we can also use a liquid fertilizer for flowering plants, to mix with the irrigation water every 20-25 days.
Irrigation Petrocosmea kerrii
Let’s water these plants only when the substratum is clearly dry using 2-3 glasses of water ; during this period of the year we should intervene every 1-2 weeks , or even less if the weather is rainy. Generally during the period of vegetatational rest it isn't necessary to water our perennial plants, which in many cases lose their aerial part.
Adversity Petrocosmea kerrii
The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favour the development of fungus diseases, which should be treated pre-emptively with a systemic fungicide, to use before the gems grow excessively; at the end of the winter we also suggest a wide range insecticide to prevent the attack of aphids and cochineals. We should always remember to do these treatments when there aren't flowerings in the garden.
Substrate Petrocosmea kerrii
Grow these perennial plants in a very well drained substratum.
