Actuallyà it is a kind of sand that slowly releases nutrients to plants. The guano più used for roses has the NPK 11-5-11 formulation, where 11 indicates the nitrogen and potassium content and 5 that of phosphorus. On the market there are also chemical fertilizers added with guano and ciò explains the NPK formulation of some commercial fertilizers.
Fertilization with guano is done twice l’ year: in March and August, or in May and September, it depends on the type of plant. In some zones with a temperate climate, autumn fertilization can be severe; carry out also in October, in others in August. The autumn fertilization, in fact, must be done before the plants go to rest. If not, the rose could be forced to vegetate again.
