When should you fertilize your roses?

Annual plan for a purely organic fertilization

At best fertilize your roses with purely organic means, because beef dung and Horn shavings(€ 32.93 at Amazon *) provide the plants with all the important nutrients. In addition, with organic fertilization the Risk of over-fertilization - react very sensitively to the roses as well as to an insufficient supply - extremely low. Organic substances decompose only gradually and very slowly, so that the nutrients gradually reach the rose (just as they are needed at the moment) and not all at once. Furthermore, the organic fertilization stimulates the soil life by manure and compost promoting the "good" bacteria. Fertilize You preferably with Cattle manure,(€ 18.79 at Amazon *) because compost should primarily be used for the purpose of soil improvement.

Start with organic fertilization very early in the year

With the application of

Cattle manure, Horn shavings(€ 32.93 at Amazon *) and / or compost can be started as early as February, but no later than the end of March, if the weather is suitable - the soil should no longer be frozen. Work the fertilizer well under and loosen the upper layers of soil after the long winter to activate the soil. In the months of May to June, ripe compost is worked in again before flowering. The last fertilization (ideally with cattle manure and / or compost) takes place again in late autumn between October and November. This point in time differs from the other fertilization plans, because with mineral fertilizers etc. should not be fertilized in autumn.

Provide roses with mineral fertilizers

Short-term mineral fertilizers should only be administered very carefully in order to avoid unnecessary environmental pollution (e. B. groundwater). In any case, many gardens tend to be oversupplied rather than undersupplied, especially with nitrogen. With short-term fertilizers, depending on the weather, you start the season between mid-March and the end of April, then fertilize between At the beginning of June and mid-July again and end this fertilization cycle with the administration of potash fertilizer between the middle and the end August. Potash fertilizers are generally said to increase frost resistance, so giving them in late summer cannot do any harm. More important for the timely ripening of the new shoots before winter, however, is that from mid-July onwards nitrogen will no longer be given. However, you can make fertilizing easier by adding minerals Slow release fertilizerswhich only have to be given at the beginning of the season in March.
