Immunity to pests and diseases is moderate, in a dry and mild climate – above average. At high humidity and unfavorable growing conditions, plants can be affected by fungal diseases. Spring preventive treatment of bushes will help reduce the risk of pest attacks.

Purpose varieties – fresh consumption, freezing, harvesting for the winter, processing. The berry grows well in open-air fields, tolerates transportation, is stored in the refrigerator for up to 3 weeks, so Gaj blackberries are often grown for sale, incl. on an industrial scale.

Growing conditions. Guy blackberry is classified as a winter-hardy variety, according to the originator, bushes do not freeze at temperatures up to –30°C. But Russian realities force gardeners to play it safe and insulate plants for the winter with agrofibre.

Worse, blackberries tolerate heat and drought, and react to excessive ultraviolet light with a decrease in yield. Therefore, agricultural technicians recommend choosing a slightly shaded area for planting blackberries and watering the plant in a timely manner.
