As you'd expect, the easiest way to water any plant is to use a watering can. Suitable for pots, planters or small-area beds, a can is the best solution for small-scale watering. There are several different types that might choose to suit your particular needs.
Made of plastic or galvanizedsteel, volume is generally around 10 litres, but can go up to 15 for the largest cans. Equipped with a wide handle, these cans are easy to use. Adaptable with a sprinkler head for a more distributed flow. Great for watering the base of large plants, vegetable plots, flower borders etc.
An exact replica of the garden can, but reduced in size! Volume isonly 3-5 litres, making it well suited to smaller spaces (balconies, patios) and window boxes, tubs or planters.
For plants in the living room or kitchen, there's no need to get water everywhere! This type of watering can is particularly suited to small pots or trays. Made of plastic, stainless steel or brass, its volume is around two litres and it has a long, thin neck (doesn't take a sprinkler head).
Without going into the intricacies of a drip irrigation system, if you have a lot of land, lots of plants or long borders, a watering can won't be the ideal solution! For efficient watering with the least wastage, you'll have to set up an automatic system.
The majority of surface systems (as opposed to underground automatic irrigation systems requiring heavy earthwork) can be connected to a water pointwith a hose. Water can be sourced directly from your domestic supply, or it can be pumped from a rainwater collector (water quality is often better because it's untreated).For completely automatic operation, you can set up a timer so that watering starts and stops at present times. Depending on the layout and nature of the plants you want to water, there are several different automatic watering methods.
This is the most widely used type of automatic sprinkler. It is mainly intended for watering rectangular areas. Thanks to the pressure of the water supply, it distributes water in a "fan" formation - several streams covering the area in question. Some models offer the option of adjusting the width and length of the jets to maximize watering of the target areas. Oscillating sprinklers aren't very well suited to non-rectangular areas (borders, flowerbeds etc.).
Ideal for lawns because the surface to be irrigated is uniform. The majority of sprinklers can be set to spray water in a straight line (in front of them), or in a circle (all around them). The length of the jets is also adjustable. This type of equipment produces awatering effect similar to rain, with the advantage of avoiding water stagnation in certain places. Thanks to several adjustable settings, it can be adapted to a range of different contexts.
These highly efficient systems operate on the drip principle. To install this type of sprinkler, you'll need a low pressure water supply (just install a pressure reducing valve that lowers and regulates the pressure to between 1.5 and 2.5 bars). A supply pipe is connected to the expansion valve on one side and a drain valve on the other. This pipe is perforated with "shuttles" (small pipes typically 4 or 4.6mm in diameter), with drippers connected at the ends. You'll need one or more drippers per trayor planter, depending on the amount of watering your plants will need. The whole setup is managed by a controller which regulates the watering cycle according to your desired settings.
In summer, watering early in the morning and / or at the end of the day is preferable to prevent the sun's heat from evaporating the water before the plants have been able to absorb it.If possible, water large areas simultaneously. Don't target your watering at certain plants or shrubs, to avoid asphyxiating the roots.Choose your garden hose with care, along with the necessary components for the various connections.For your vegetable garden, water generously until harvest time. Lack of water reduces growth, especially for legumes growing in the soil.If you live in a particularly cold or frosty area, make sure to drain all your pipes and sprinklers and store them under cover over winter.
