Fertilize when planting the raspberries
You can already ensure a good supply of nutrients when planting the raspberries in your garden.

Never place new raspberries on a place where other berry bushes such as blackberries have previously stood. These soils are very depleted and take some time to recover.
Prepare the soil well. Loosen the soil deeply and mix it with ripe compost, rotted stable soil or peat.
Fertilize while growing
During the growing season, fertilize your raspberries twice.
The first fertilization takes place in spring. This ensures that the shrubs receive enough nutrients to produce lots of fruit. After the harvest, there is a second application of fertilizer. It serves to strengthen the plants for the coming year.
Avoid fertilizing your summer raspberries just before the July harvest or your fall raspberries in August. Some fertilizers affect the aroma of the fruit, making them watery.
Natural fertilizer for raspberries
The following are suitable as natural fertilizers for raspberries:
- Horn shavings
- Nettle manure
Raspberries do not tolerate fertilizers containing lime or chloride. It is therefore better to rely on natural nutrients. You can produce many of these organic fertilizers yourself.
Mulching instead of fertilizing
Mulching the raspberries has several benefits. The soil remains weed-free. This is to protect the summer raspberries from rod disease.
The mulch cover is a natural protection that prevents the soil from drying out. Raspberries love an evenly moist environment without waterlogging. With a mulch layer you create an ideal growth climate.
The mulch material rots over time and releases many nutrients in the process. They penetrate the soil and thus act as a natural fertilizer.
Suitable materials for mulching
- Bark mulch
- Lawn clippings
If you use lawn clippings, make sure that the grasses are well chopped up. The grasses must not have formed any inflorescences. Otherwise there is a risk that a layer of grass will form under your raspberries.
Only lay out healthy leaves as a mulch cover. Leaves with pests or fungal diseases should be disposed of entirely and not used in the garden.
Fertilize the raspberries in the pot
You need to fertilize raspberries in the pot more often, as the soil in them quickly leaches out. You should change the entire soil every two years so that the plants receive enough nutrients.
Tips & Tricks
Since raspberries are very frugal plants, a special raspberry fertilizer is not necessary. A raspberry fertilizer can only be given when the soil is already very depleted. However, it is often better to choose a new location for the raspberries.
