Roses are much less demanding than many gardeners think when it comes to giving fertilizers. We will inform you about when and with what they should be fertilized.Roses are not demanding
Proper care of roses also includes fertilizing. Even if the noble roses are quite undemanding, it is important year after year that you administer the individual fertilizer doses correctly so that the flowers can bloom in full splendor. If you fertilize roses incorrectly, it can happen that they do not grow properly and their flowering is not very profuse.
When should you fertilize roses?
1. Fertilization in spring:
You should regularly supply roses with well-rotted compost, and this in early spring, so that they can be carefully awakened from their hibernation.
You should always give compost when planting, as this will make it easier to grow.
2. Fertilization from mid / late May:
As soon as the rose forms the first buds that open easily (usually from mid / late May), you can administer the first full fertilizer. But never earlier, as this would significantly weaken her bloom! Ideally, you should use a liquid fertilizer for this full fertilizer application. Then apply it immediately after a downpour, because then the soil is optimally absorbent for the fertilizers administered.
3. Fertilization in late July / early August:
You can then give another mineral fertilizer at the end of July / beginning of August, before you end the season in late autumn by heaping and covering the individual rose bushes (hibernation).
You don't need to fertilize roses that you put in very nutrient-rich soils that are well supplied with compost. Alternatively, you can also incorporate a little coffee grounds around the rose bush.
The situation is different if the roses have been exposed to a lot of downpours in one season, because these give fertilizers quickly seep into the soil. Then you even have to fertilize three times.
What should you use to fertilize roses?
Three types of fertilizer are absolutely vital for roses - compost, complete fertilizer and mineral fertilizer, whereby for the latter special rose fertilizers are now even available in specialist shops.
If you don't have your own well-rotted compost, you can alternatively add horn shavings, animal manure or a little peat to the soil. You should always work all fertilizers well into the soil.
➤ Full fertilizer:
The rose also needs a complete fertilizer, which you best administer in the form of a liquid fertilizer. It is best to use a special rose fertilizer. You really can't go wrong with that because the bottles always describe exactly how to use this fertilizer.
➤ Mineral fertilizer:
And to top it off, roses also need a mineral fertilizer, which you should choose depending on the prevailing soil conditions on site.
Important: do not over-fertilize roses
Under no circumstances should you over-fertilize your roses, as this damages their vitality. If you have planted the individual roses in an extremely nutrient-rich soil, for example, then once a year it is enough to incorporate compost once.
