Centranthus ruber - Red valerian

continental : These plants prefer a sunny location, where they can enjoy direct solar rays even throughout the whole day,
These plants are grown in the garden year round because they are rustic.

alpine : Let's grow the The Centranthus ruber in a sunny place, with direct solar light.
These plants are rustic, they can stand the heat and cold, therefore they can be planted outside.

mediterranean : Plant which needs a few hours a day of solar light.
These plants can stand the cold weather, they can be grown as garden plants during the whole year.

continental : During this time of year very frequent watering is advised, even daily if the climate is very hot and dry; let’s try to keep the soil cool and damp. Irrigate every 0-1 weeks, during the evening or morning hours.

alpine : The Centranthus ruber should be watered regularly, to maintain the substratum slightly damp using 14 litres of water; if the climate is very hot and there are scarce precipitations it might be necessary to water every 1-2 weeks, or more often than that.

mediterranean : We suggest watering often, trying to keep the soil slightly damp with 16 litres of water, but avoiding excesses; the forming of water stagnations also harm those plants which love wetness, usually the frequency of watering is every 0-0 weeks.

Feed Centranthus ruber : Summer fertilizations should be regular, using a fertilizer for flowering plants, to mix to the irrigating water, every 10-15 days; it’s also possible to use a granular slow release fertilizer, with an action which lasts 3-4 months.

Adversity Centranthus ruber : Summer treatments should be applied only in cases of displayed infesting; a dry climate favours the development of ticks and rust. During this period of the year, since there are many useful insects in the garden, it is advisable to avoid using wide-range products, favouring the use of specific products against each type of parasite. Let’s apply the treatments during early morning or evening hours.
