In order for the graceful roses to thrive and develop their decorative flowers every year, they should be given enough fertilizer. However, they do not need a lot of fertilizer and should therefore not be over-fertilized. It is therefore important for the rose bushes to have a long, healthy life, to only fertilize them at certain times. The following article therefore also deals with the ideal seasons for fertilizing.

season
In order for the graceful roses to thrive, develop beautiful flowers and be strengthened against diseases, they need different nutrients. These should also be given at different times of the year. The plants need fertilizer, but only little and well distributed throughout the year. Therefore, three doses of fertilizer a year should be enough if you use the right means. The different times are as follows:
- in the spring
- May / June
- August
Every time for fertilization has its justification and should strengthen the roses in a different way. Therefore, one general fertilizer cannot be used and none of the three fertilizations in the year should be omitted. With every fertilization, attention must also be paid to the individual nutrients and minerals that the plants need at the specific time of year.
spring fertilization
In spring, when the first warm temperatures are expected, the roses should receive their first fertilization. For the time, the respective climate zone in which the roses were cultivated must also be taken into account. In some areas it is already the end of February, in others only in March. Since fertilizing in spring is intended to help the roses with the addition of special nutrients when they sprout again, the ideal time is to choose immediately after the rose bushes have been cut. The following should be noted here:
- ideally use compost
- or cow dung
- contains all the nutrients you need
- work directly into the root area
- needs a lot of phosphate for the formation of flowers
- as well as nitrogen for good growth
- for this addition of horn meal
- also potassium
- Soil analysis can help
- then suitable fertilizer can be selected
Fertilize in May/June
As a rule, most varieties of roses remount. After the first flowering, further buds are formed on further new shoots, which open in summer. As a rule, these more frequently blooming roses are cut after the first bloom in May or June. In this way, a new shoot can be promoted. To support this, the roses should be fertilized again immediately after pruning, because the new shoots cost the plants a lot of energy. This should be done as follows:
- rapid effect of the fertilizer desired
- resort to mineral products
- Blue grain is ideal
- dose only a little
- no more than 20 to 30 g/sqm
- liquid fertilizer for roses can also be chosen
August fertilization
Fertilizing in August should strengthen the roses for the cold season. It is therefore important that you choose the appropriate nutrients and special fertilizers here as well. The fertilizers that were given in spring and summer to promote new growth and flowering are now not wanted. For the winter, on the other hand, the roses need a fertilizer that helps the rose shoots to harden sufficiently and thus become frost-resistant. The following should be considered when choosing the fertilizer:
- high in potassium
- little to no nitrogen content
- Nitrogen leads to the formation of new shoots
- no longer desired from August
- Potassium stimulates plant metabolism
- Cell fluid in roses does not freeze as quickly
- use special fertilizers from the trade
- alternatively spread compost or mulch around the plants
- Nutrients can thus constantly reach the roots
- also offers protection from the cold
