High beds are one of the popular ways to organize a garden economy or flower garden. It is not surprising that the owners of suburban areas are interested in how to make high beds with their own hands for growing various crops. You can build such beds in a greenhouse or in an open area, and the effect is guaranteed when all the rules are followed.
The essence of the elevated arrangement
A high bed is a plot of fertile land elevated 30-50 cm above the surface. At its core, they are an artificial bulk site, which is much more convenient to care for plants. Such raised beds have a standard design: a restrictive barrier (frame) along the entire perimeter and a multilayer fertile soil, which is filled up according to certain rules. Naturally, an irrigation system should be provided. A high garden bed in a greenhouse may also include a heating system.
High beds are favorably used in areas where the climate is not entirely favorable for growing plants. The height of such structures allows you to bring the fertile layer out of the freezing zone, since on the earth's surface much earlier the sun's rays provide heating. In general, the following advantages of high beds can be distinguished: the possibility of optimal use of purchased soil; ease of maintenance (no need to bend during work); ease of arrangement of drainage; getting rid of weeds; providing natural heating; the possibility of self-arrangement.
The choice of material for the frame
The soil of a high bed is held inside the frame in the form of a kind of trough, while its wall can be of different heights, and the frame itself can have a different shape (rectangle, circle, etc.).
The reliability and durability of the bed, as well as its design, depend on what material the boundary wall of the frame is made of.
Most often, the following materials are used as the material for the frame:
- Wood. High beds from boards are widely used, which is caused by the simplicity of arrangement, decorativeness and naturalness of wood, ecological purity of the material. An important condition: do not use second-hand wooden products with harmful impregnation (for example, sleepers) or a dangerous coating.
- Walls made of bricks. Such fences can be built at different heights and various shapes, and the advantage provides high strength and durability.
- Wattle. Fairly simple and cheap design in the form of interwoven branches. An important disadvantage: rash and leaching of soil through gaps, quick drying of the earth. At the same time, gaps provide aeration of the soil. Installation of the system is time-consuming, but can be done without financial costs.
- Metal. You can make high beds from used metal - sheet, corrugated board, various metal profiles.
- Concrete. The fence can be built by pouring concrete into the formwork. When using concrete, it should be borne in mind that within 1.5-2 years, the adjacent soil sections will experience increased acidity.
- Plastic is considered the most modern and promising material for high beds in the garden or beds in the greenhouse. You can pick up a sheet of an already finished form or bend it according to the selected project.
How does the soil fall asleep
The inner fertile part of the high beds can be performed in different ways. The greatest popularity was gained by 2 options: a warm bed (hotbed) and arrangement without digging.
A warm high bed is prepared by filling it with several layers of soil. The lowest layer (on the surface of the earth or with a slight deepening) is formed by geo-fabric. On top of it, a drainage layer of a mixture of sand, grass, rags, and waste paper is poured. Fertile soil forms above: peat and fertilized land. The total height of such beds is 35-50 cm. After filling, it is recommended to pour plenty of hot water and cover with a plastic film on top.
The technique without digging consists in backfilling the soil in the trough of the frame and subsequent maintenance without digging it. Such a structure should not be walked on and should not be rammed. Organic fertilizer is applied periodically. Mulching of the soil is actively used.

Recommendations for arrangement
When preparing a high bed, it is recommended to follow certain rules:
- The place is best equipped on compacted soil, among the lawn, so that the sun falls on the site for at least 5-6 hours per day.
- The upper, fertile layer should be at least 10-15 cm.
- Before planting, the earth is abundantly spilled with water and left for 3-4 days under a plastic film.
- The optimal width of a typical rectangular bed is 125-130 cm.
- The soil should be fluffy and crumbly.
- The bed should be equipped with an irrigation system: a common method is a hose with watering nozzles around the perimeter, perpendicular or at an angle of 120 °, as well as the use of drip irrigation.
- When growing plants with a long stem, it is advisable to establish a trellis - this is how cucumbers, beans, etc. are grown.
- The long side is better oriented in a southerly direction.
- It is necessary to take measures to eliminate the influence of strong winds.
- Landing on a high bed is on average 2 times denser than on a regular bed.
High beds are found by an increasing number of admirers in areas with risky farming. Such structures belong to warm systems and allow you to get an earlier harvest. You can equip them with your own hands, taking into account the design features.
