About strawberry frigo goes a lot of rumors. This is an opportunity to get a harvest all year round, and the ripening of berries six weeks after planting, and resistance to all diseases ... What is the truth of this and is it worth rushing for seedlings?
The very phrase "strawberry frigo" is more like the name of the variety and this leads to confusion in the minds of beginner gardeners. It is necessary to figure out what kind of berry and what are its features.
What is strawberry frigo
So, frigo is not a variety, but a technology for preparing strawberry (horticultural strawberry) planting material. It consists in the following.
Uterine strawberry bushes of the most high-yielding varieties in the spring are planted in light ground (sandy or sandy), fertilized and do not allow them to bloom, so that the plant can direct all its forces to reproduction. Hatching young bushes also regularly feed and await their maturation. It occurs in November, when the foliage of the strawberry acquires a brown shade, and the rhizome becomes uniformly brown, only at the tips remaining white.
Mature plants are dug, transferred to a cool room, shaken off the ground, but not washed and not cut. Then all large leaves are removed, and only young leaves remain on the bush. After the plant is treated with fungicides (Fundazol, Topaz, Hom, etc.), sorted according to size, tied into bundles of 50-100 pieces and sent to storage.
Strawberry frigo seedlings are stored in special conditions - folded into thin plastic bags and left in refrigerators. The chamber must maintain a stable temperature from 0 to -2 ° C and a humidity of no more than 90%.
Subject to all norms, bushes can be stored in a frozen state from 2 weeks to a year without loss of yield and up to 3 years - with its decrease.
Varieties and classes of strawberry frigo
The technology of freezing when growing strawberries implies a strict classification of the bushes depending on the diameter of the root collar. In total, Europeans allocate 4 classes, and the price of strawberry seedlings of frigo will depend, first of all, on him, and not on the variety.
- In class - diameter of the root collar is 8-12 mm, 1-2 peduncles, fruits in the second year after planting.
- A- class - diameter of the root collar is 12-15 mm, 2 peduncles, fruit bearing in the year of planting, up to 20 berries from the bush subject to the agrotechnology.
- A + class - root neck diameter 15-18 mm, 3 or more flower stalks, 25-40 berries from a bush.
- WB class - root collar diameter is over 22 mm, more than 5 peduncles, more than 450 g of berries from a bush in the year of planting.
According to the technology of frigo, the most high-yielding and resistant varieties of garden strawberries (strawberries) are grown. Most often this Alba, Clery, Honey (Honeyoje), Elsanta, Sonata etc. The largest Russian nurseries engaged in strawberries frigo, offer more than 80 varieties.
How to keep strawberry frigo seedlings
On sale seedlings of garden strawberry frigo can be found from January to May, and both in ordinary garden stores and online stores. The planting material prepared for transportation is packed in sphagnum moss, which excludes the appearance of rot and mold. In this form, Frigo can be on the way to 3 weeks without loss of quality.
Acquired planting material must be carefully examined. If the bushes have not woken up yet and there are no leaves on them, you can continue storage in the refrigerator at a temperature range from 0 to -2 ° C. If the bush has already begun to form leaves, you will have to plant it.
How to grow strawberry frigo
It is possible to land both on ridges (if the planting season has already begun) and in pots (if it is still far from spring). You can also temporarily plant the bushes in small pots (up to 500 ml), and with the onset of heat, plant them in a permanent place.
The scheme of proper planting strawberries Frigo in the ground
Before planting, the roots are pruned to 10-12 cm, straightened and lowered into the soil so that they are distributed, lay flat, without creases, and not in a ball, but freely. The soil should be well moistened, and after planting, immediately seal around the bush. The seedlings do not have leaves, so you need to closely monitor the level at which the root rosette is located. Dumping it with soil can cause the roots to soak when watered, and free exposure to air can dry out.
The soil for strawberry frigo should be very nutritious, and prepare it, as a rule, in the fall. On 1 sq. M of land contribute 10 kg of rotted manure, 30 g of potash salt and 60 g of superphosphate. It is best to plant strawberries on high ridges in 1-2 rows and mulch with agrotextile or straw.

Pros and cons of free technology
Of course, there are many advantages to modern technology. We only note the main ones:
- high yield;
- ripening ripe berries after 8-9 weeks after planting in the ground;
- guaranteed healthy planting material;
- high rate of seedling survival;
- availability of many varieties suitable for different regions and climatic zones;
- the ability to harvest in the "off season".
However, there is a overseas miracle and cons:
- seedlings are more expensive than usual;
- strawberry skoroplodna only 1 year of life, and then no different from the usual berries.
According to professional gardeners, growing strawberry frigo is a real breakthrough. So maybe you should try unusual and very promising seedlings already in the coming season?
