The subtleties of growing raspberries in a greenhouse all year round

Raspberries in a greenhouse - checked way to get a high yield until late autumn.

Indoor ground allows you to provide the required level of moisture, plants are not afraid of frost, hail, strong wind and other vagaries of the weather.

To begin with, it is worth starting a small greenhouse, over time it will be possible to significantly expand the raspberry tree.


Growing in a greenhouse has a lot of advantages:

  1. The ripening period of the berries is extended until late autumn. During this time, all the berries that have set have time to ripen, the yield from each bush increases noticeably.
  2. Indoors different varieties can be grown, differing in color, shape and taste of berries, ripening times.
  3. The greenhouse protects plants from the vagaries of the weather, which is especially important in spring and autumn.
  4. Raspberries grown in a greenhouse are less likely to be affected by pests; they do not need to be treated with harmful chemicals.
  5. Indoor ground provides the right level of humidity, which guarantees excellent fruiting and high taste of berries.

Why all year round?

Gardeners who rely on greenhouses usually use them from early spring to late autumn. During this time, you can get two crops of remontant raspberries.

But the process can be made continuous. For year-round cultivation need a spacious a greenhouse with a heating system and a separate place for the mother liquor.

Conveyor planting will help ensure a continuous period of fruiting. The first plants are planted in a heated greenhouse in January. After 1.5-2 months, fruiting begins.

In March, the second stage of raspberry seedlings is planted. Plants that have finished fruiting are pruned and dormant. A continuous crop requires constant feeding and frequent replacement of bushes. The conveyor growing method is quite economical. It is necessary to heat the greenhouse from the end of September to the beginning of October, around the clock no backlight required.

Despite the obvious advantages, the remontant raspberry there are also disadvantages:

  • compared to summer classic varieties, the berries are less aromatic;
  • remontant varieties very demanding on the soil, it should be loose, nutritious, not too sour;

Among the most popular remontant varieties:

Ruby necklace - very productive, berries are large, bright red, fragrant.

Apricot - a fruitful variety with beautiful yellow-orange berries with a pleasant fruity flavor.

Hercules - a very large-fruited variety with excellent productivity, up to 8 kg of berries can be harvested from a bush.

Morning dew - compact bushes with good yields. The berries are rich yellow, very pleasant to the taste.

Orange miracle - large-fruited raspberry with orange-yellow aromatic berries.

Bryansk miracle - a highly productive variety, the berries are large, rich red, with a delicate pleasant taste.

Raspberry greenhouse

From spring to autumn, raspberries are grown in a greenhouse without heating. In it you can harvest until November, after that the plants are cut off and left for the winter. Some gardeners leave the summer greenhouse open, freezing destroys the larvae insects. Most varieties of remontant raspberries tolerate winter calmly.

The summer greenhouse is most often made arched and high enough. It is being erected without a foundation, on a metal frame. The greenhouse is covered with polyethylene or bent honeycomb polycarbonate. Designs with removable end panels are very convenient, allowing you to open the plants on hot summer days.

Winter greenhouse needs a solid foundation and double doors to keep cold air out. Design maybe arched or pitched, you do not need to make the greenhouse too high.

Repaired raspberries are compact, the bushes are low, a small amount of shelter will reduce heating costs.

The most durable structures are built on a frame made of galvanized metal profiles; paid plastic film, tempered industrial glass or polycarbonate are used as a coating. For winter shelters ordinary glass cannot be used and wooden frames that do not provide good thermal insulation.

Repaired raspberries love bright light, so you need to equip the greenhouse with lighting around the entire perimeter. For heating you can use an electric boiler or infrared cable, but modern compact wood-burning stoves are much more economical. A pair of ovens is enough to heat a greenhouse with a size of 50 sq. m.


The seedlings are purchased from proven nurseries that guarantee the purity of the variety. In the future, the bushes for updating the plantation can be grown independently, taking part of the greenhouse under the mother plant.

In the greenhouse a trench is being dug 40 cm deep and up to 50 cm wide. Young plants are planted in it at a distance of 60 cm from each other, row spacing is 2 m.

When planting, the root collar should be at the level of the ground surface. After planting, the soil around the plants is well compacted and watered abundantly.

Raspberries very demanding on the nutrient content of the soil... It requires a light substrate of garden soil, peat and sand or vermicult.

Heavy, clayey soils impede the normal development of seedlings and severely reduce yields. For greater nutritional value, humus is introduced into the soil mixture, as well as a mixture of mineral fertilizers.

Top dressing are held at least once every 2 weeks... It is recommended to alternate organic matter and mineral fertilizers, adding them together with watering. Raspberries respond well to urea, superphosphate and ammonium nitrate; during active growth, nitrogen-based fertilizers are needed.

The culture is very hygrophilous. In the greenhouse, raspberries are watered 2 times a week. Bushes do not like stagnation of moisture in the soil, therefore, at least once a week, the soil must be loosened. Simplify caring for raspberries mulching will helpthat retains moisture in the soil.

The space around the bushes is abundantly covered with sawdust, straw, humus or nutshells. Watering is carried out at the root, in the left holes. Instead of organic mulch agrofiber can be usedcovering the entire soil surface. Holes are cut for plants through which watering is performed.

In the warm season, you need to open the greenhouse doors as often as possible, and it is better to completely remove the end frames. Fresh warm air ensures better development of seedlings, insects necessary for pollination gain access to the greenhouse.

Raspberries calmly react to daily temperature drops. Ideal for greenhouses - 20ºC-22ºC during the day and 13ºC-15ºC at night. Air humidity should not exceed 75% and fall below 65%.

The flowering of the bushes begins 6-8 weeks after planting in the greenhouse. With the beginning of flowering, the dose of nitrogen fertilizers is reduced by 2 times, while complex mineral and organic fertilizing continues.

Harvesting is best in the morning. The day before harvesting, the bushes are not watered so that the berries become sweeter and more aromatic. Plucked it is advisable to place the berries in the coldso they don't give juice. You cannot shift them, tender raspberries quickly lose their presentation.
