Organization of a warm bed on the site is one of the effective ways to bring closer the timing of planting seedlings of vegetables in the greenhouse.

With the onset of the first warm days, the air warms up rather quickly, but the rays of the still weak spring sun are not enough to warm the soil. Arranging warm beds in the greenhouse will help speed up this process.

Why do we need warm beds in a greenhouse?

The principle of operation of a warm bed is quite simple. With a lack of solar energy in the spring, soil warming occurs very slowly. Adequate temperature for planting is not reached until late April or early May.

If they ate the soil artificially, you can create favorable conditions for planting in March.

At the same time, plant roots immediately fall into comfortable conditions, quickly take root and begin to develop. Part of the heat gets into the air and also contributes to its warming up.

Creating warm beds in various ways

The answer to the question of how to make a warm garden bed in a greenhouse is simple. There are several options for heating the soil in a greenhouse:

  1. Electric.
  2. The advantage of this option is the ability to fine-tune heating intensityas well as control of the reached soil temperature.

    To create, an electric cable is used, placed in a layer of geotextile, laid to a depth of 40 cm. The cable is laid in rows at a distance of 15 cm between them.

    Such heating has a thermostat in the design, which automatically regulates the temperature. The relay is configured in such a way that the cable heats up to 25-30 degrees, and then turns off.

    The greatest energy consumption of such beds falls on the early spring - 20 kW per day, then the energy consumption is halved.

    IN hot period heating can be disabled, and again use it in the fall, to continue the fruiting period of plants.

  3. Water.
  4. It is based on PVC pipesthrough which hot water is passed. This system also acts as a heating system in the winter, and the greenhouse can be used all year round.

    To ensure the circulation of liquid in the system, a pump is mounted, and a water heater (gas or electric) is used for heating.

  5. Biological.
  6. Warm beds in this case are created using biofuelslaid under a fertile soil layer. Experienced gardeners recommend preparing biofuel for the greenhouse with their own hands.

    Biological material laid in the garden during processing actively generates heat and thereby warms the roots of plants.

    Used as a filler manure and various plant residues, sawdust, wood trimmings. Horse manure gives the highest temperature, it is able to keep the temperature about 70 degrees for a month and a half.

    In addition to horse dung, cow dung is suitable. But experienced gardeners do not recommend using pig and sheep manure as biofuel.

IMPORTANT. Do not use fresh manure as filler, as it can burn the plant roots.

Cooking filler for a warm garden

Beds using biological materials are the most environmentally friendly and at the same time economical. To warm up the soil in such a bed, the costs of their arrangement and maintenance are not needed.

In addition to the thermal effect, this option enriches the soil with nutrients and carbon dioxide. Plants are kept in warm soil and get enough nutrition. In doing so, they become resistant to disease.

The ideal filler for the garden bed is a layer of rotted manure. Various plant residues, foliage, cut branches are mixed with it.

If there is no manure, freshly cut grass mixed with food waste, potato peelings may well serve as a filler.

You can fill the garden bed with straw bales, which are watered with a solution of chicken manure or Baikal top dressing.

Last year's tops mixed with fresh humus can also be laid in the garden in the fall.

Compost bed

The traditional compost heap created on the surface has many disadvantages. It is laid in a fairly high layer in the fall and freezes through in winter. In the frozen layers, the decay process does not go, which means that decomposition does not occur and the summer resident does not receive ready-made compost by spring.

In addition, such a high layer will thaw in the spring later than the use of compost will need to be used. Another disadvantage of such a heap is its maintenance in the summer.

An unpleasant sight and smell, periodically watered with slops, delivers a lot of unpleasant sensations. Flies fly over the heap, maggots begin to crawl along the edge, this phenomenon causes a lot of inconvenience not only to you, but also to your neighbors in the area.

An expedient way to prepare this biofuel is to create a compost trench bed. It is dug to a depth of 40 centimeters, the top layer is deposited, and the pit is filled with plant debris. In the fall, falling foliage is laid in the same trench.

To start the fermentation processes, the vegetable compost filler is spilled with slurry or grass infusion. The surface of the trench can be covered with roofing felt or a piece of linoleum. It is better to lay them on the air access poles.

For the winter, the compost trench is covered with a layer of sawdust and covered with a layer of snow to avoid severe freezing.

In the spring, the trench becomes a source of efficient biofuel for laying in a warm bed.

Foliage compost

Fallen foliage is an excellent material for composting biofuels. There are two options for generating compost in a greenhouse to generate heat:

  1. Foliage compost heap for heating the greenhouse.... The foliage is laid on the surface of the soil, and a certain amount of ready-made compost is added to it to start the decomposition process.

    From above, the pile is covered with straw or bags. This is necessary so that the foliage does not dry out, but rot. The composting process takes two years. The pile is periodically watered.

  2. Compost pit... To make it, a two-meter wide and 30-40 centimeters deep hole is dug in the ground. The bottom is covered with a film or roofing felt.

    Fallen leaves are laid in layers, each of which is spilled with a solution of nitrate and sprinkled with a small amount of turf soil. The next layer is spilled with slurry.

    This is followed by a layer of caustic soda. Next, a layer of foliage is laid, sprinkled with wood ash. On top of this sandwich is covered with straw, and then turf, laid with grass down.

    After a month, the pit must be loosened for oxygen access and mixing of all layers.

REFERENCE. The use of plant waste and branches as a filler for warm beds solves the problem of recycling plant waste at the site. Instead of simply destroying them, they serve as fuel and fertilizer for other plants at the same time.

Rules for the formation of a warm bed

Process making a warm bed in the greenhouse they begin with the onset of the first warm days. It is made in the form of a trench, into which various fillers are laid in layers.

The main condition for the normal operation of a warm bed is its sufficient volume... The bed is about 90 centimeters wide and 40 cm deep, the length depends on the size of your greenhouse.

Like any garden bed in a greenhouse, a warm one must be made using a wooden, metal or any other frame.

This will allow you to get required height, as well as to prevent soil eruption and leaching during the cultivation of vegetables.

REFERENCE. Ready-made aluminum sides for garden beds are very convenient to use. They are durable and easy to install.

When laying layers of a warm bed, some conditions must be observed:

  • The bottom layer should contain the largest fractions for slow decay and increase the heating period;
  • When using a layer of turf, it is laid with the grass down;
  • Each laid layer must be spilled with liquid, there should not be dry layers in it;
  • Plant waste affected by any disease should not be placed in the garden bed. Exceptionally healthy plants are used.

ADVICE. To protect plants from rodents, a fine mesh is laid at the very bottom of the trench.

The bottom of the dug trench is laid with drainage. The material of the drainage layer depends on the quality of the soil in your area.

On peat soils, the bottom of the trench before laying branches should be covered with a thick cloth, and a layer of sawdust or chopped bark should be poured onto it.

This technique will prevent excessive water seepage during irrigation. On the opposite loam, you need to provide outflow of excess moisturetherefore, the bottom is covered with large branches left over from shrubs pruning.

The next layer is biofuels: manure mixed with plant residues or any of the fillers available. To accelerate decomposition, the layer is spilled biological product.

The biofuel layer is well compacted and covered with fertile soil. For nutritional value, a mixture of peat, humus, earth and sand is prepared. Superphosphate, wood ash, urea, potassium sulfate are also added.

IMPORTANT. Experienced gardeners advise to lay the fertile soil not immediately. And after 2-3 days, the field of laying biofuels.

The layer of fertile soil should be at least 30 centimeters. All layers are spilled with hot water and covered with black foil to warm up. After a week, the garden bed is ready for planting seedlings.

IMPORTANT. If you are an adherent of organic fertilizers, chemical elements can be omitted.

A properly made warm bed in a greenhouse accelerates timing of planting seedlings, which means it increases the yield. A greenhouse with such beds does not need to be heated, and there is no need to apply additional fertilizers. Plant care is simplified. We hope you now know exactly how to heat the greenhouse with your own hands in the spring, and also what is the best way to do it.
