Whether in the garden or in a pot: you have to fertilize roses. The plants have a high need for nutrients and only develop their full bloom if they are adequately supplied with fertilizer. This is especially true for remounting roses that bloom even twice a year with proper care. Even so, regular nutrients are essential for a long flowering period. In our guide, we clarify the most important questions on the subject and reveal when, how often and with what you need to fertilize your roses in order to enjoy the unique flowers.

How should you fertilize your roses?

Rose growers and professional gardeners rely on cattle manure or special rose fertilizers from specialist dealers when fertilizing roses - both perfectly meet the needs of plants.

To keep roses healthy and blooming, they primarily need organic fertilizer that contains nitrogen, but also phosphate and potash. If the last two nutrients are sufficiently present in the soil - this can be determined with a soil analysis - horn meal is recommended for fertilizing. This releases nitrogen much faster than horn shavings because it is so fine that it decomposes quickly. In summer, small doses can also be used to apply mineral fertilizers such as blue grain, which also works very quickly. Make sure that you do not apply more than 30 grams per square meter - otherwise the new shoots will not mature sufficiently and will not wood in time for the winter. The result: frost damage.

When are roses fertilized?

Fertilize your roses for the first time in spring, just before budding. The flowering shrubs start the new season with full force. The second fertilization takes place in summer, beginning until mid-July at the latest. You can use mineral fertilizer that stimulates the plants to flower again. Do not fertilize later, as most roses are not completely frost-resistant and their winter hardiness is further reduced by fertilizing too late.

Fertilize roses in the garden

Beef manure is the first choice if you want to fertilize your roses in the garden. In addition to its valuable ingredients, it also enriches the soil in the flower bed with humus. However, it should be well seasoned and at least six months old before being spread out. Here's how:

  • Remove any weeds in the root area.
  • Spread out about half a pitchfork / shovel full of cattle manure.
  • Carefully work the fertilizer flat into the ground using a cultivator such as a hand cultivator.

Garden tip: It is easier to get cattle manure in the countryside than in the city, for example by asking farmers from the region. Rose lovers will also find what they are looking for in well-stocked garden centers in the city: They offer dried beef manure in the form of pellets.

Fertilize potted roses

The numerous varieties of roses decorate not only the garden, but also the terrace or balcony. In the pot, they are usually supplied with rose fertilizer from the trade and not with cattle manure, the smell of which you do not necessarily want to have right in front of your nose. If you use depot fertilizer, the effect lasts an average of four to five months. Normal liquid rose fertilizer is given every two weeks from spring to July. Just pour it into the watering can when watering. Follow the prescribed dosage instructions exactly to avoid over-fertilization.

Roses in pots are particularly dependent on regular nutrient administration - they are fertilized from spring to mid-July.

Controversial: patent potash for roses

The question of whether you should fertilize your roses with patent potash is a hot topic among rose lovers, professionals and hobby gardeners alike. Basically, potassium has a reputation for increasing the frost hardness of plants so that they can get through winter better. In the case of roses, however, opinions differ: While some achieve excellent results, others hardly see a difference. One should know, however, that patent potash lowers the pH value of the soil in the long run and it becomes acidic. The roses can absorb nutrients more and more poorly if used improperly. You can counteract this with occasional lime additions.
