- planting can be carried out both in the spring and in the fall (spring planting lasts from late April to mid-May, and in autumn plants can be planted starting in October);
- the size of the planting pits may vary depending on the diameter of the root system of the seedling;
- when planting, it is imperative to install a wooden or metal support for fixing the bush;

The grape variety “Radiant” is demanding enough to conduct competent and timely care measures. It must be remembered that the plant needs preparation for the winter period: mulching the soil and equipping the shelter.
Irrigation measures should be carried out regularly and be relatively moderate. The volume of water used for irrigation depends entirely on the type of soil on which the vineyard is cultivated. On chernozems, about five buckets of water should be used to irrigate each plant. In the presence of sandy soil, the volume of water for irrigation is about nine buckets.
About ten days before the harvest, irrigation measures should be discontinued. When growing grape raisins, it is recommended to use drip irrigation systems.
To increase the amount of green mass in the spring, nitrogen-containing preparations should be applied under the vineyard. Recommended for top dressing. Plantofol. The annual application of potassium monophosphates, sulfates and magnesium sulfate has a beneficial effect on productivity. The main fertilizer should be carried out before flowering. Overfeeding of vineyards with fertilizers helps to delay flowering and inferior formation of ovaries.
Grapes should be formed so that for every square meter of the area there are no more than ten well-formed shoots. The total load on young plants should be about ten shoots. For adult plants, you can leave twenty shoots. The distance between adjacent arms should be about one meter.
Optimal for growing grapes of this variety is to perform long pruning for ten eyes. Proper pruning will allow you to get a well-formed brush and a couple of large clusters for each shoot. Exceeding such indicators threatens with crushing berries and reducing their quality characteristics. When the plant is overloaded, a delay in the ripening period of the crop is often observed.
