From traditional sprinklers to underground systems with programming, you will find a range of equipment that meets the various requirements imposed by the plants grown and the size of the land.
- Traditional watering cans
- Spears and sprinklers
Traditional watering cans
• The classic watering can is now almost always plastic with reinforced bottom (sometimes zinc). The capacity of a watering can is of 10 or 12 l, but one finds smaller ones, for the greenhouse and for the interior (houseplants). The apple, removable, can be eventually replaced by a ramp for the application of liquid fertilizers. Greenhouse watering cans have a thin beak that releases a narrow stream, so as not to damage the fragile stem of the plants.
Hoses and reels
• PVC pipes opaque are preferable to translucent pipes which, in the long run, can be blocked by algae forming in the light. They exist in various qualities and in different diameters. They are characterized by their resistance to pressure and weather, as well as their internal diameter.
• The pipe used for common uses withstands 3 bar pressure; its internal diameter is 15, 19 or 25 mm. There are also PVC pipes for watering under high pressure (up to 10 bar).
• Rubber hoses are still in favor of high pressures (and in regions with harsh climatic conditions): we use a reinforced rubber, canvas, which can last a very long time.
• A reel prevent the hose from dropping on the ground and getting damaged. Use a model mounted on wheels or a wall system.
Spears and sprinklers
Simple or sophisticated systems allow the distribution of water at the outlet of the pipe.
Spears and pistols
• Attaching a nozzle or spray gun to the end of a hose is the easiest way to disperse the water. The classic spear is made of brass; the adjustment by screwing or unscrewing the body of the lance makes it possible to obtain a pressure from the right jet to the fine mist. It is also hard plastic
• The guns include a trigger trigger that can sometimes be locked in the "on" position. These lances are usually hand-held, but there are also metal mudguards that are used to hold them in place for prolonged watering.
• Known for a long time as "tourniquets", they ensure a uniform watering on a circular surface.
• The turnstiles are placed in height, mounted on an adjustable tripod for watering high position of the plants and shrubs, or placed at the level of the ground, on low tripod or on sled, for diffusion in low station (watering under the trees, for example ).
• They have two rotating arms: it is the force of the pressure of the water that drives the movement; in the high position, the rotary ones provide the watering on a diameter of about ten meters. "Swirl" type models have three arms.
• They allow a constant dispersion of water and provide a fine and regular rain. There are several models whose systems differ significantly.
Garden boom: it consists of a triple perforated pipe (flattened shape). Its orifices are arranged in such a way that it ensures a fine and uniform rain on a rectangle 4 to 5 m wide. This boom is suitable for fragile seedlings and plants. It can be placed between two rows of plants and left there during the dry season.
Saucer Sprinkler: The diffuser is fixed on a plastic plate that is placed on the floor. It provides a vertical stream that falls in rain and water in a circle, of variable diameter depending on the pressure
(in the order of 8 m in general for standard devices).
Diffuser on stem: this fixed sprinkler comprises a diffuser placed at the top of a hollow metal rod in its upper part and ending in tip at the other end, to be stuck in the ground, and a double connector of arrival of self-locking water. This device makes it possible to fix several rods in series.
They consist of a rod pierced with holes that are driven into the ground, like a stake, with a water intake on the surface. These devices are suitable for deep-rooted plants (trees and shrubs) and prevent losses from runoff. These sprinkler stakes are especially suited to light soils.
• The drip system ensures water supply over a long period of time, eliminating
runoff losses, but also siltation. The drip does not wet the leaves (magnifying glass, the drops may cause burns).
• It is the best system for adding fertilizer during vegetation (by mixing liquid fertilizers with water).
• A drip sprinkler consists of an irrigation plant, a main pipe, distribution pipes and drippers.
• Attention: when it is too calcareous, the water can quickly block the drippers.
Oscillating boom sprinklers
• They consist of a ramp pierced with holes and sprinklers, which oscillates in a rather slow movement under the effect of the pressure of the water. They allow to water according to a rectangle, leaving the soil a sufficient time for absorption.
• The boom can be set to different positions, depending on the width of the band to be watered.
• This type of equipment can be mounted on sled, and thus moved easily (just pull on the pipe).
It is very interesting to water specific surfaces. Its mechanism is however quite fragile.
Spitting sprinklers (so-called water cannons)
• They allow circular diffusion over a larger diameter than rotary systems.
They turn slowly, jerks, producing a jet interrupted (it is the interruption of the jet that causes the increased pressure).
• The spitters are adjustable and can only water a portion of a circle (from the sixth).
They produce a jet that reaches a dozen meters, which corresponds to a circle of 24 m
• They can be placed on the ground, on a sled (sometimes with a retractable stabilizing post) or on a tripod. They are suitable for all vegetable and amenity crops. The jet they provide goes slightly upward and falls down in rain.
• They are particularly suitable for large vegetable gardens and lawns, and are recommended in areas where it is necessary to water often.
This system gives the soil a certain absorption time (and avoids the loss of water by runoff).
Automation and programming
• In recent years, various systems have come to improve watering.
Sprinkler with automatic advance: The garden hose automatically wraps around the reel and moves the sprinkler on a sled. This system is practical on lawns (it requires a strong enough pressure).
Sprinkler with differentiated adjustment: stationary watering station equipped with movable adjustment guides which allow to water very diverse surfaces.
The programming systems are very convenient for gardeners who do not have much time and especially for weekend gardens. The simplest system is the timer, which goes up with a key and is located at the exit of the tap. It must be triggered manually, but stops automatically. A battery-operated timer is set up as a time switch and thus provides shutdown and shutdown.
There are also sets of programs that control the watering, at various times, of several circuits of the garden; this system is suitable for second homes. Twilight automatic triggers are also found (watering starts at dusk).
They are suitable for all vegetable gardens. On the practical level of watering, they do not differ from conventional systems since the diffusers are fixed.
The quality of pipes and fittings is important (all major brands offer robust and easy to assemble materials). These systems are suitable for gardens in fairly dry areas, where watering must be very regular.
