From each square meter of raspberry orchard, about 6 kg of berries can be harvested annually. First of all, you need to plant a variety on your site that is capable of blooming and bearing fruit repeatedly during the season. But in order to get such a rich harvest, you still need to know and follow 8 rules for caring for remontant raspberries.

Top dressing, watering, soil loosening and mulching
In order for a plant to flower and bear fruit, it needs nutrients for this. Repaired raspberry varieties are sensitive to a lack of nitrogen fertilizers. For this reason, fertilizing the garden must begin in the spring. As a top dressing, you can use aqueous solutions:
- mullein (1 part fertilizer per 10 parts water);
- chicken droppings (1:20).
For 1 sq.m. a raspberry garden requires 3-5 liters of organic fertilizer.
You can also fertilize with dry dressings. In early spring, about 2 kg of humus can be added under each bush. When the raspberries bloom, they should be fed with a mixture of potassium sulfate (20-40 g) and superphosphate (50-80 g).
Watering of remontant varieties of raspberries is carried out depending on weather conditions and the number of berries on the bushes. The roots of the plant are close to the surface, so the culture is difficult to tolerate drought. If the summer is dry, you should water your garden frequently and abundantly. The soil near the bush should be 35-40 cm wet. Moisture will allow the berries to grow large. During the rainy season, watering should be stopped.
To retain moisture in the soil, protect bushes from overgrowing with weeds, warm the root system in winter and protect against overheating in summer, soil mulching will help. As mulch, you can use:
- non-woven fiber (at least 50 g / m2);
- peat;
- sawdust;
- compost;
- straw;
- humus, etc.
It is necessary to mulch raspberry bushes immediately after planting the seedlings. It is also necessary to renew the mulch annually. After compaction, its layer should be more than 5 cm.
The root system requires oxygen for good development. Therefore, in order to harvest a rich harvest during the season, the soil must be loosened. In order not to damage the roots, you should not go deeper into the ground more than 10 cm. In row spacings, a loosening depth of up to 15 cm is allowed. During the season, it is necessary to carry out about 6 loosening.
Pruning, thinning, watering, protection from pests and diseases
If the gardener plans to harvest the remontant variety once, pruning is carried out in autumn or spring. All branches are removed without leaving stumps. When it is planned to collect raspberries 2 times per season, then in late autumn or spring, before the buds bloom, the old shoots (which already had fruits) are cut out, and the young are shortened. Cut 15-20 cm from the top.
If raspberries were planted this year, then young bushes are not completely cut in the fall. It is necessary to leave shoots about 20 cm long.
Thinning involves cutting off the branches that lead to thickening of the bush, which negatively affects the normal development of garden culture. To make the bushes strong and less vulnerable to disease, it is recommended to leave 8-9 fruiting shoots on each plant. It is also necessary to monitor the health of the garden throughout the season. Those branches that have been affected by the disease are also removed.
Under the weight of the harvest, raspberry branches can break off, so it is recommended to tie them up. As a support, you can use stakes stuck in the ground near a bush, or trellises (trellises). If berries are collected from a remontant bush 2 times per season, then it is necessary to tie up old and young shoots separately.
Repaired varieties are resistant to pathogenic microflora, but, like other types of raspberries, they need preventive treatment against pests and diseases. To prevent fungal infections and destroy the larvae of some pests, it is recommended to treat the raspberry garden in spring with Bordeaux liquid (1%). Re-spraying is carried out in the fall, before wintering.
