Varieties of cucumbers are divided into parthenocarpic and pollinated by bees. A novice gardener should be aware that in the greenhouse it is better to grow varieties or hybrids that do not require pollination. They are unpretentious, less susceptible to disease and very productive. The first reason for the poor growth of cucumbers is a violation of terms of planting. As heat-loving plants, on the ridge planted when the average soil temperature is 10-12 degrees. Cucumbers grow seedlings or sowing seeds directly in the ground. Thus they should be treated with a solution of potassium permanganate. The plants will be less susceptible to diseases. Seedlings ready for planting at the age of 25-30 days and in the presence of 5-6 true leaves on the stem. Another reason of weak growth of cucumbers - not enough power plants during the growing season. Please note some of its characteristics. The fruit is gnarled, stunted - not enough nitrogen. Water the plant and let the roots of the urea solution. The sheets, yellowed at the edges or cucumber in the shape of a pear, symptoms of a potassium deficiency. Feed with sulphate of potash or wood ash solution. After fertilizing spraying plant growth stimulant that enhances root nutrition reduces the content of nitrates and promotes stronger flowering.For good growth, cucumbers require the mandatory creation of the lashes. Since the tab is the most productive of the ovaries is formed on the side shoots, pinch at a distance of 40-50 cm, and the main stem of the plant are cut once they reach lengths of 80-120 cm Cucumbers may grow poorly with a lack and excess of moisture. Seedlings watered in small doses 2-3 times a week and only in warm weather. Cold water should not be used. It is better to use pooled rainwater. To encourage better blooming, stop watering for 5-6 days before it starts. Too wet soil is bad for plants, it induces the growth of lashes at the expense of fruiting and provokes the development of rot. Watering cucumbers at the root, so as not to cause the initiation of disease by moisture on the leaves. If you cultivate bee pollinating varieties, it is desirable to spray the plants with a solution of sugar in Earl grey infusion every 2-3 days until the end of flowering. This bait attracts bees. The result is increased harvest, and cucumbers do not get sick. Regularly inspect the planting. At the end of the second month of fruiting the leaves of cucumbers can become rough and prickly, slowing down the formation of the fruit. The plants will come alive and the leaves will become soft, if you spray them with a weak solution of urea. The appearance on them of the white spots indicates such a frequent disease as powdery mildew. In this case, a very good solution for spraying home cooking: in 9 liters of water pour 1 liter of skim milk or whey and add 10 drops of iodine. For prevention of this disease in the period of plant growth is carried out continuous spraying of the solution every 10 days. Only 4 of the course. The second most common disease is Anthracnose. The sheet on the upper side has a rounded spot, and at the bottom emerges the plaque pink. The pink fruits are covered with sores. At an early stage of disease is to remove damaged leaves and plant spray 1% Bordeaux liquid. There are many pests that interfere with the normal growth of cucumbers. Chemical substances are toxic, so use herbal infusions. For example, against aphids helps the infusion of garlic.
