Greenhouse cucumbers. Varieties and care

Cucumbers are different: small and large, early and late, salad and pickled, lumpy and smooth-fruited... The list can be continued according to other parameters, but we will talk about greenhouse cucumbers. Why are they in demand among many gardeners?
Many people grow these vegetables in greenhouses to get an early harvest. After all, cucumbers are heat-loving and ripen later in open ground. Having good greenhouses, you can eat fresh cucumbers almost all year round, if you properly organize care and select the right seeds.
Cucumber varieties for greenhouses are divided into winter-spring, spring-summer and summer-autumn. Each of these groups is also divided into early-ripening, mid-ripening and late-ripening, bee-pollinated and parthenocarpic. The latter were precisely created for growing in closed conditions, where there is no constant access to insects. Early varieties are usually of the salad type. They are tasty, but do not produce such a large harvest, and are more often susceptible to various diseases. Some varieties require large, spacious greenhouses (Dynamite F1) due to constant growth and formation of ovaries, others need artificial pollination, and others need good heating.
Cucumbers are quite picky about conditions. To get a good harvest, you need to use fairly fertile soil with a high humus content or special mixtures. Choose varieties and hybrids specially bred for our conditions. After all, the best Dutch variety can lose to the domestic one only because it has different requirements for soil, climate, diseases and pests.
