Being confined to our homes, we will certainly have more time to take care of the plants in the garden, the indoor plants, the planters or the vegetable spot. Irrigation then does not seem to be a problem. However, less watering of plants has many benefits. Even as the hottest months approach, we know we will have to water longer. Otherwise drought is guaranteed and flowering is bad! In fact, with all these little tricks, you can waste less water and save a little in the summer. And best of all, when it’s a little airy or on vacation, it’s always reassuring to know that plants won’t die of thirst in a few hours! Here’s our tip for the gardener who wants to water the plants in pots or the ground less often.
1) Less frequent watering starts with the right plant choices
It is well known: plants have very different water needs. Some Shrubs and flowers are very water intensive and need a more intense irrigation density. some plants are on the other hand much less and therefore you must logically turn to these if you want to water less often. Of the desert areas, cacti (cactus, leek, etc.) come to mind first. However, it is not just succulents (also called siblings)!
You can also try aromatic plants, both useful and beautiful. These include lavender, thyme, sage, bay leaf or rosemary. Think too orchid which likes without excessive watering, as long as it is in a bright corner and at a comfortable temperature. Althea, ornamental garlic, morning church, santolina, sweet wildflower, scottish broom, sedum, California poppy… there is no shortage of low water plants!
2) Water the plants at the right time to do it less often
When it’s hot it is recommended to water in the evening to limit water evaporation related to sun exposure and heat. In fact, colder temperatures in the evenings allow the soil to hold water better. For example, by watering at noon 60% of the water evaporatesbecause the ambient temperature is higher. On the other hand, the evaporation rate will be only 10% in the evening. Make a calculation: if the average price / m3 of water is € 3.05 and you water every 2 days for 5 months, this means a saving of around € 34 per year in a 100 m² garden! Pretty good, right?
3) Apply mold to the root of the plants
In its natural state, bare soil does not exist. In our gardens, the soil is usually poorly covered, which may be possible leads to water loss. Here comes a mold that reduces water intake by maintaining moisture in the soil. This also allows the floor to be protected when hot. By heating less, the water evaporates faster. In addition, some coverings also nourish the soil, which is always a Plus! Here you can choose textile, mineral (pozzolan, ceramic waste, crushed slate, etc.) or organic material (straw, wood chips, grass cutting, dead leaves, etc.). You can also put clay stones in a pot during replanting and mold to retain moisture in the soil. Just avoid pine bark or needles that acidify the soil.
4) Select the correct sprinkler system
If you choose your irrigation system well, you can target better and save money. This therefore precludes a garden hose and its strong flow that is difficult to control ! And if automatic watering with a timer is practical, you can also rely on a simple spray or drip irrigation system. Indeed, this allows for controlled irrigation directly at the plant feet level through a small network of pipes.
5) Do you especially want to save water? So try this!
If you want to reduce watering to save money, this last point interests you! It is, in fact, atips for collecting water. For this purpose, it is of course possible to install a rainwater collector. However, that does not end there. You can already recover the cooking water from eggs, pasta or vegetables. That water must be unsalted and chilled before watering. By using these nutrient-rich waters for irrigation you will avoid wasting and your plants will be healthy! Finally, it is also possible to recover water from your aquarium. It contains a lot of nitrogen, such as garden fertilizers. This is an unusual reservoir of water excellent for watering flowers and greenery.
