How do you know if your plants in the garden are watering too much or perhaps too little? And when is the best time to water plants? Especially when there is little rainfall in the summer and the weather is often warm for a long time, it is important to provide sufficient water. This certainly applies to plants in flower boxes. Therefore, some useful tips for watering plants.
Give plenty of water twice a week
In the summer you prefer to water the garden for an hour (or two) once or twice a week rather than a short time every day. According to Lieuwe Westra van Tuinkeur, people often think too easily about watering. According to him, that is unjustified. “Watering is a profession in itself. You see that some people, for example, water for ten minutes every day. But it is often better to water thoroughly twice a week because only then will your plants get enough. ” If you give a little water every day, the bottom of the roots will not receive enough water.
Spraying twice a week for an hour is better than a little every day.
Give extra water in a heat wave
When the weather is very hot, for example during a heat wave, plants use their own weight in water. The sun is burning all day and the plant has to get through that scorching day. If you do not water during the day, there is a good chance that they will simply die. It is precisely on those days that they can therefore use extra moisture. Especially in the evening give extra water. The idea that watering in the sun causes burnt leaves is not true, says plant biochemist Stuart Thompson of the University of Westminster. This only applies to leaves with hairs on them. In those plants, the water droplets are kept ‘at a distance’ from the leaf surface, so that the sun’s rays pass through and a focal point can be created.
Water in dry soil
Do you have moisture-poor soil in the garden, such as sandy soil? It retains water and nutrients less well than, for example, clay soil. That means watering more often and improving the soil for good sowing and planting. A tip is to use a soil improvers that plants grow well on.
A sprinkler system offers a solution if you have a larger garden. Turn it on for a while in the evening or morning.
When is the best time to water plants?
Watering plants is best done in the morning, at the end of the afternoon, or at the beginning of the evening. Then the sun is less bright or has disappeared and plants can absorb the water better. Watering in the sun is not a good idea. If you do that, the water evaporates much faster, even before it is absorbed by the plant. Place potted plants in the shade in warm weather and / or water them several times a day.
Look at your plants
A tip is to take a good look at the plants so that you can estimate whether they have had enough water. If not, the leaves may droop or even discolor. If you really wait too long, leaves will be shed for self-protection. Because of the fewer leaves, the less water the plant needs. Still, you are not too late. Lieuwe: “This does not mean that the plant is dead, but you do have to take action now. You can spray your plants with the watering can or with the garden hose. ”
Plants in flower pots need a lot of water in warm weather.
Water plants from below
Preferably spray at the base of the plant, both with garden plants and plants in pots. This way you pour the water directly close to the roots and the plant can absorb the water faster. In addition, fungi can develop on the leaves of some plants if they (often) get water on the leaves. Pay extra attention to flower pots and tub plants, even after a rain shower. Species with large leaves or flowers can dry out because the rainwater often does not reach the earth. Tip: create an elevation around thirsty plants that you have just planted so that the water cannot drain quickly.
