Variety selection

In the confined space of greenhouses, it is better to grow compact bush hybrids. They take up less space, but they are distinguished by good yield and high taste of fruits.

For indoor ground, early-ripening varieties are chosen; they can be planted throughout the year, without interruption in harvesting. Ideal for greenhouses - F1 hybridsspecially cultivated for indoor use.

It is better to choose plants without thorny growths on the stalks, they are easier and more convenient to collect. Small-fruited varieties with fruits of a light or medium-saturated shade are preferred for sale. Several dozen varieties and hybrids have been created for indoor use.

White-fruited - the variety is suitable for both protected and open ground, but in a greenhouse, the yield is significantly higher. The variety is bushy, compact, does not form long lashes. Large greenish-white fruits with moderately dense creamy pulp have a delicate, non-watery taste.

Greenhouse requirements

Zucchini are undemanding to the conditions of detention. They grow well not only in expensive polycarbonate greenhouses, but also in simple film shelters. Greenhouse height is not important, however, for the convenience of caring for plants between the ridges, you need to make a fairly wide passage.

A greenhouse for zucchini can be small, up to 50 sq. m. Such space will provide a good harvest. If you plan to grow zucchini in winter, you need to build a greenhouse on a foundation, covering wooden or metal frames with glass or polycarbonate.

The greenhouse needs equip with vents for ventilation and heating system. You can warm up the greenhouse using an electric boiler or wood-burning stoves; for greenhouses covered with plastic, household heaters are suitable. Expensive greenhouses are equipped with automatic drip irrigation and climate control systems.

The ideal way to heat greenhouses is with biofuels. This economical option is especially loved by zucchini, because it warms not so much the air as the roots of plants.

To prepare fuel, rotted pork, goat or cow manure is mixed with straw in equal proportions, piled up, spilled well with water and on leave under the film for several days.

Then the top layer of soil is removed in the greenhouse, biofuel is evenly distributed and cover with a layer of nutrient substrate... Such a pillow not only warms the plants, but also serves as additional feeding during the period of active growth. The emitted carbon dioxide contributes to the rapid ripening of fruits and an improvement in their taste.

Growing secrets

How to grow zucchini in a greenhouse? Growing zucchini in a greenhouse is available not only to experienced, but also to novice gardeners. This crop prefers light, well-loosened soil, neutral or slightly alkaline. For more nutrient content in the soil compost and ash can be added.

Instead of organic matter, you can apply complex mineral fertilizers, mainly superphosphate. Zucchini react negatively to preparations containing chlorine. Top dressing is applied every 2 weeks simultaneously with watering and loosening. All weeds must be removed before fertilizing.

Zucchini it is more convenient to grow seedlings... The seeds are sown in peat pots, this makes it possible to preserve the fragile root system during transplantation. Seedlings that have reached the age of 20-25 days are moved to the greenhouse, to a permanent place.

The distance between plants is from 70 to 80 cm.In film greenhouses, zucchini planted in early May or a little earlier... With early planting, it is necessary to preheat the soil using ovens or electric boilers.

Mulching will help maintain normal moisture levels and accelerate ripening. After planting, the soil is covered with a foil in which holes are made for the plants. Watering is carried out in these holes. Sawdust mulching possible, sunflower husks and other materials. The ground cover provides the zucchini with the warmth they really need.

Plants do not like greenhouses that are too hot and humid. The optimum temperature for successful fruit ripening is 24 degrees during the day and 18 degrees at night. Humidity is maintained at 60-70%... When the temperature rises, the plants can shed the ovaries; with a strong cold snap, the growth of squash slows down. You need to water the bushes once every 5-7 days, preferably soft water at room temperature.

Daily the greenhouse needs to be ventilated... On warm spring and summer days, zucchini should spend most of the time in the air, this accelerates ripening and attracts insects for pollination. For additional attraction, the plants are sprayed with sugar syrup dissolved in water. You can also pollinate zucchini manually using a cotton swab.

For better ventilation and maximum access to light from plants remove the lower leaves... At the same time, there should be no less than 15 formed leaves on the bush. This procedure is necessary for thickened plantings.


Harvesting should begin when the first fruits reach the desired size. Don't wait until they get too large. Small zucchini tastes more delicate, their rind is soft and glossy. Watering stops 7 days before cutting... This technique allows you to make the taste of the fruit more intense, not watery.

During active fruiting, zucchini is harvested every other day. Harvest very carefully, trying not to injure the tops of the bushes and the formed whips. Damaged plants do not recover well and can stop the formation of new ovaries.

When collecting fruits, it is important to remove not only beautiful and full-fledged, but also ugly, malformed fruits. Overgrown zucchini left on the branches will delay the development of new ovaries and reduce the yield of each bush. Care must be taken when cleaning, the skin of young fruits is prone to damage and scratches. Injured zucchini are worse stored and quickly lose their presentation.
