A common problem of many summer residents is the partial, if not complete, destruction of the cucumber harvest. Therefore, the question of why cucumbers are dying in a greenhouse and how to prevent it is still relevant. Growing perfectly groomed crops that will produce 100% of the crop is a challenge to perform. Cucumbers are a delicate and susceptible culture to external factors; therefore, newcomers have a lot of trouble with it.
Causes of the death of cucumber bushes and fruits
Fading leaves and twisted fruits - a problem not only for beginners, but also experienced gardeners. The reasons for this behavior are many, so greenhouse owners need to find out in more detail what violations have been made in preparing the beds, planting the crop and daily care.
- Fungal diseases are the primary attack that affects garden crops, including cucumbers. White rot spreads quickly throughout the plant, softening tissues and turning them into mucus, as a result of which cucumbers die. The crop does not grow at all, or its quantity is minimal.
- All cultures suffer from pests, if you do not pay attention to the fight against them. Today, the market for agricultural products offers various means to combat aphids, whitefly and other harmful insects. One has only to choose a suitable drug and carry out processing according to the instructions.
- Root rot begins to manifest itself even before the bushes began to bear fruit. It may appear during the formation of the fruit and during fruiting. This disease indicates that the gardener made some mistakes in the selection of planting material. Possible violation of presowing seed preparation.
- Improper construction of the beds is a common problem faced by novice vegetable growers. Having no experience, the gardener can build a too high bed, and this is fraught with the rapid evaporation of water. As a result, cucumbers disappear, because they do not have time to get enough moisture.
- Failure to comply with the temperature regime is another mistake of inexperienced summer residents. It is necessary to clearly understand that cucumber is a heat-loving culture that reacts painfully to temperature changes. If the greenhouse is not heated properly, the leaves will first fade, and then the crop may follow. This problem is easily eliminated by adjusting the temperature balance in the greenhouse.
Knowing about the possible occurrence of such problems, the summer resident can take the necessary measures to obtain a bountiful harvest.
About pests and diseases
Common pests that attack and spoil planted cucumbers are aphid and the greenhouse whitefly. Insects devour not only the leaves, but also the roots. You can get rid of them, without resorting to shoplifting, but using simple materials at hand:
- To get rid of the whitefly, just find a piece of plywood, paint it yellow, and then cover its surface with a sticky substance. Yellow color attracts this pest, and sitting on a sticky surface, it is trapped.
- To get rid of aphids, you can prepare garlic solution in a ratio of 1:10.
Most often, cucumber suffers from downy mildew, root and gray rot:
- Mealy dew appears as white spots on the leaves of the plant, which eventually grow, the leaves themselves begin to turn yellow, and the plant to die.
- Downy mildew also manifests itself in the form of spots on the leaves of cucumber, but only a green shade. They grow, turn yellow and cause the plant to dry.
- Root rot appears when improperly planted seedlings, when watering a plant with too cold water. As a result of such actions cracks appear on the roots, and the plant dies.
- Gray rot can be found on the grayish spots on the stem and leaves. They are the result of soil freezing and poor ventilation of the greenhouse.
How to equip a greenhouse so that cucumbers do not fade
In order for cucumber seedlings to quickly take root in a new place, it is necessary to think about how to properly cultivate the soil, namely its quality will influence the growth of the crop and its further fruiting.
Therefore, all the soil in the greenhouse must be properly dug up, weeded from weeds, remove all the remnants of previous plants, and then fertilize properly.
Fertilizer land - an important point, as the minerals and other useful trace elements infiltrate the soil and provide adequate nutrition for young cucumber seedlings.
Do not forget about fumigating the greenhouse, which disinfects the space and ensures safe development of cucumbers. This can be done immediately after transplanting. Fumigation will eliminate pests and other microorganisms that can harm the cucumber. To carry out proper fumigation, all the doors and windows in the greenhouse must be tightly closed. After that, it is necessary to take kerosene, lump sulfur, put all this into a container and set it on fire.
Heating in the greenhouse is an equally important point; the right temperature will ensure an excellent crop of cucumbers. Here it is necessary to take into account the characteristics of a particular variety.
For early greening, all early-maturing varieties and some hybrids are suitable, for example, Suomi F1, Saratov F1 and Valaam Hybrid.
The most important thing is to remember the rules of care and love your job, then young seedlings in the future will give a tasty and bountiful harvest.
