Remontance is the ability of a crop to bear fruit throughout the entire growing season. Raspberries of remontant varieties are characterized by the fact that berries can appear not only on last year’s shoots, but also on annual shoots. Of course, this significantly increases productivity and allows you to enjoy the taste of raspberries twice a season: in mid-summer and early autumn.
But in the Siberian regions, such raspberries must be grown in compliance with certain rules - in a harsh climate, remontant varieties behave differently than usual.
In order to achieve high yields of sweet berries even in Siberia, it is necessary to find the most suitable one for specific conditions. raspberry variety.
What are the characteristics of raspberry varieties for Siberia?
In conditions of a short summer, when spring frosts can drag on until the first ten days of June, and autumn colds begin in September, the most important thing for a gardener is to have time to harvest raspberries. Indeed, in such a climate, most varieties of remontant berries simply will not ripen.
That is why gardeners in Siberia are recommended to grow remontant raspberries only on young shoots. This significantly shortens the growing season and allows you to save up to 40-50% of the crop, which risks dying from autumn frosts.
With this method of growing, raspberry shoots must be pruned every autumn so that in the spring the bush will form anew and the berries will ripen only on young branches.
Remontant raspberries have a whole several advantages before the usual varieties for the Siberian regions:
- Gives consistently high yields.
- It is less likely to be attacked by pests and has strong immunity against diseases and infections.
- Does not require shelter for the winter, as the shoots are simply cut off.
- Additional shoots do not appear from the roots of remontant varieties, the bushes do not thicken - it is more convenient to care for such raspberries.
- The harvest is formed already in the first season after planting raspberries. Every year the number of berries ripened on the branches will grow steadily.
- Almost all varieties of remontant raspberries are of low or medium height, so you don’t have to build strong supports for them.
How to grow remontant raspberry varieties
The rules for planting and caring for remontant raspberry varieties in Siberia are practically no different from other regions. Briefly, they can be formed in several points:
- Raspberries are planted in the spring (from April 20 to May 20, when the snow melts) or in the fall (throughout September). In Siberia, it is still better to plant bushes in the spring, so that the raspberries have time to acclimatize and not freeze in the first winter.
- In order to prolong the growing season of raspberries, it is recommended to plant bushes on the southern slopes of the site, in an area that is well lit by the sun and reliably protected from cold northern winds, near walls or fences that will reflect light and accumulate heat, thereby warming the bushes.
- The soil for remontant raspberries should be crumbly and very fertile, because many berries ripen on the bushes - the plants need to be watered abundantly and well fertilized.
- It is necessary to plant remontant raspberries according to the following scheme: the distance between bushes is 80 cm, row spacing is 150-200 cm. The depth of the hole for a new bush should be at least 40 cm. Humus and mineral fertilizers are poured into the bottom of the hole, mixed with soil and placed there raspberry bush. The bush is buried so that the upper basal bud is approximately 3 cm underground. The earth is lightly tamped and the bush is watered abundantly.
- To maximize the preservation of the nutritional properties of the soil, it is recommended to mulch the distance between remontant raspberry bushes. For these purposes, you can use peat, high-quality humus or rotted sawdust.
- Raspberries should be fertilized at least three times per season. To do this, it is good to use cow manure diluted in water or purchased mineral components.
- Remontant varieties need to be watered abundantly - large berries need a sufficient amount of water to fill. As a rule, bushes are watered several times during the summer - it all depends on weather conditions and the amount of natural precipitation.
- Raspberries should be in the sun, so bushes that are too thick need to be thinned out, removing unnecessary shoots. If the berry ripens in the shade, it will not be sweet and runs the risk of becoming infected with gray rot.
- The berries of remontant varieties are very large and juicy, there are a lot of them and they greatly weigh down the branches. Therefore, strong supports about 1-1.5 meters in height should be installed near the raspberry bushes.
- Harvesting is carried out after 2-3 days - the berries should not overripe. This will have a bad effect on their taste, shelf life and overall yield of the bush.
- You should not plant remontant raspberries in the place where blackberries, nightshade crops or raspberries of any variety grew in the past three seasons.
- On cloudy and cold days, raspberries are very susceptible to fungal infections and gray rot. Therefore, the bushes must be inspected and preventively treated with fungicides that are safe for humans.
