6 Steps to the Perfect Grape Variety
It is very difficult without experience to choose the perfect grape variety. There are certain recommendations.
Covering or non-covering
For the northern regions of the country, it is better to choose only covering varieties, since the risk of freezing a variety in winter is quite high. Therefore, in principle, choose any variety that has powerful trunks and large fruits. Any grape variety is suitable for the southern hemisphere.
Late or early
Ripening dates directly depend on the duration of heat in the summer. In the northern latitudes of the country, there is not much heat, even despite the long summer day, so do not rely on the terms described in the characteristics of the variety. For the northern regions, grapes with an early ripening period will be relevant (Tukai, Kishmish, Timur and etc).
Ideal grape variety and temporary shelters
The weather in the north is absolutely unpredictable, spring may come much later than the calendar period and be cold, summer may not be hot, and autumn is too early. Spring frosts are also possible, even at the beginning of summer, short-term frosts are possible. Therefore, in areas of northern latitudes, it is recommended to use mini greenhouses in spring and autumn. In hot weather, the covering material is removed. The volume of the greenhouse is calculated from the size of the bush, so it is recommended to choose undersized and medium-sized bushes.
High fertility at the base of the bush
The peculiarity of some varieties is that green shoots that grow from perennial wood, at the base of the bush, necessarily give a bunch. These varieties include - Violet early, Rusbol, Druzhba, etc.
Ideal for disease resistance
The main diseases powdery mildew and mildew are not widespread in the northern regions, however, with the introduction of southern planting material, the risk of infection increases. Be sure to carefully choose seedlings, in case of infection, use chemical protection methods. The appearance of small fruits is also possible - pea (stenospermocarp), this comes from poor pollination of the plant. Try the rabbit puff pollination method. Or feed with drugs to stimulate fruit formation.
Taste and color
When all five stages have been passed, proceed with the selection of the taste and color qualities of the grapes. Here, the choice is limited only by your preferences. And then you will find the most ideal grape variety for yourself.
