Raspberries are not only totally delicious and refresh us in summer with their sweet and sour taste. They are also very healthy. No wonder that more and more hobby gardeners are bringing this power fruit into their garden. So that the plants can produce a lavish harvest every year, they have to be cut twice a year.
When and how you have to cut your raspberries depends on whether they belong to the summer or autumn varieties. The summer varieties include all raspberries, the fruits of which are ready for harvest in summer. As a result, all raspberries, the fruits of which you can harvest in autumn, belong to the autumn varieties.In the summer varieties, only the shoots from the previous year bear fruit. The autumn raspberries, on the other hand, bear fruit on the shoots from the current calendar year.
Tip: Twotimer raspberries bear fruit twice a year. As a young shoot, each shoot bears fruit for the first time in autumn and a second time in summer of the following year. They are cut just like the summer varieties.
Pruning after harvest
For both varieties, the shoots should be cut off just above the ground immediately after harvesting. This is how you can prevent the so-called raspberry rod disease.
When cutting back the autumn raspberries, you don't need to pay much attention. After the autumn harvest, simply cut off all shoots close to the ground. With a flat layer of leaves you protect the flat roots from frost and dehydration.
Tip: Leave some healthy shoots lying around. These serve beneficial organisms such as the predatory beetle, a winter quarters, so that they can be active again next year.
Pruning summer raspberries is a bit more difficult. Here you have to differentiate between old and new shoots. The shoots from the previous year, which have borne fruit in the current calendar year, must be cut off close to the ground.
Tip: When you harvest the last raspberry, it is best to remove the corresponding shoot immediately. So you can not confuse the old shoots with the new shoots.
The young shoots will bear fruit in the coming summer. So that they can grow more abundantly, they should leave a maximum of ten plants per running meter.

Raspberries sometimes form a lot of side shoots, so the fruits might not get enough light. This could result in the fruits turning out smaller and less sweet. It also promotes fungal diseases. For these reasons the shoots may need to be thinned out. Here it is important to differentiate between the summer and autumn varieties.
Tip: You can get a better yield right from the planting. Read our article "Raspberries - More Yield Through Correct Planting".
Educational cut for summer raspberries
After the last frost - around the end of February - you should take a close look at the shoots that you left in the previous year and see if you need to remove side shoots. Note that fewer side shoots mean fewer fruits, but more powerful and tasty raspberries.
Tip: First, cut off the side shoots that are difficult to reach. These are usually the lowest branches. You can also shorten the rods in height so that you can harvest the fruit there with little effort.
If you have thinned out the shoots, you should loosely attach them to a trellis at a height of 30, 100 and 180 centimeters. This will prevent the plant from tipping over under the weight of the fruit.
Educational cut for autumn raspberries
When summer begins, you should also make an educational cut on autumn raspberries. Since you are only dealing with young shoots here, you can leave between 15 and 20 rods in the running meters and cut off the remaining rods close to the ground. Make sure that the remaining shoots do not constrict each other and shorten the side shoots here if necessary.
Tip: A support structure at a height of about 80 to 100 centimeters ensures that the plants do not tip over later under the weight of the fruit.
Care cut possible at any time
Check your raspberry plants regularly. So you can intervene immediately if you discover sick or pest-infected shoots. If you do not remove them immediately, they can also infect other shoots.
In addition, you should also make sure that the raspberries do not sprout too much. Both too dense and too high growth is not exactly advantageous. So also take suitable cutting measures between the development cut and the cut back. However, make sure that you do not shorten the shoots during flowering.
