In summer, watering plants is a priority! The health of our plants is at stake. But what if you don't have a green thumb? The classic questions then arise: when to water? How much? What technique should be favored for it to be effective and for plants to regain vigor… To prevent your summer flowers from having a sore head, we called on Stéphane Frisson, Category Manager Garden - Plant at Jardiland who gives us his maintenance tips. Let's go for the gardening session!
What time of day is it best to water your summer flowers?
Prefer watering in the evening during hot weather to limit evaporation and in the morning when the nights are cool.
Is daily watering necessary?
Contrary to popular belief, it is absolutely not necessary to water your ornamental plants daily. In normal periods, sufficient and spaced watering (every two or three days for example, depending on weather conditions) is more in line with the natural needs of the plant. In general, note that it is better to wait until the soil has become dry again so as not to risk an excess of water and thus drown your plant.
Do all plants have the same water needs? How to respect their specific needs?
All plants do not have the same water, sun and soil needs ... In order to best meet the water needs of each of our plants, we can consider three main types: * Water-hungry plants which need to be watered when the soil surface is dry (every day in hot weather). * The reasonable (plants with lower water requirements) which should be watered when the soil is dry for two or three centimeters. * Plants with low water consumption which will be watered when the soil is dry to a depth of five to eight centimeters.
What do you think is the preferred watering technique?
Three main types of watering are used in the garden. Not all of them necessarily have the same purpose. The first is the so-called manual watering. This involves watering your plants with a watering can or a garden hose. Tedious but particularly effective, this technique is particularly suitable for watering summer flowers. The second, sprinkler watering, consists of watering in the form of rain using a sprinkler or sprinkler. It is particularly suitable for large beds and rock gardens. The last, probably the most effective and economical is drip irrigation, also called micro-irrigation. The latter is ideal for watering summer plants. Indeed, the water flow provided by the drippers is adjustable therefore adaptable to the needs of each plant. Also note that this technique is of great interest in the greenhouse, on the terrace or on the veranda, in the event of repeated absence, in the vegetable patch, for hedges and flowerbeds.
Is there a solution to limit the evaporation of water after watering?
Mulching is an excellent natural alternative to avoid water evaporation. This practice consists of covering the soil at the base of cultivated plants with materials of plant or mineral origin such as pine bark, hemp, flax flakes, cocoa pods or simply straw. Interest? Not only does mulching limit water evaporation, thereby reducing watering, but it protects the soil and regulates its temperature. In addition, it enriches the soil, promotes plant growth and limits the development of weeds. There is therefore every interest in opting for mulching.
Similarly, according to the popular saying, "1 hoeing = 2 waterings". Also, once the watering has been carried out and the soil has been drained, a light hoeing of the surface will prevent too rapid evaporation of the water.
