Gavnø’s castle gardeners recommend placing roses in a sunny, open location in a humectant, nutritious soil.
Roses should be fertilized twice a year (March and May), if they are single-flowering and four times a year (March, April, May and June), if they are remounting.
Prune roses in the late winter / early spring (March). Cover the roses with fallen foliage and greens when the winter is at its peak.
