To think ecological, the recipes are simple: just put plants that require little maintenance and are adapted to the soil, while limiting mechanical and chemical interventions as much as possible. Amaury Gallon, landscaper-botanist, testifies.Interview by Charlotte Cousin
What plants do you recommend when building an ecological garden?
We must take the decision to put plants that do not prune, rarely mow and are not very fond of water. Grasses that have few pests are the typical example of the plants that require the least maintenance; if you are taking persistent grasses, there is no pruning to do. The flowery meadow made up of perennial flowers, field flowers and grasses, requires only one mowing per year to have a rise of flowers. If you want it to be made up of perennials, you just have to select vigorous plants, not very prone to diseases, like verbenas or valerians, which are naturally seeded.
What materials are recommended?
What is interesting is to use recycling materials. You can use slate petals recovered from falling roofs and make a mulch to coat and protect the soil. You can also make mulches of straw, cocoa or pine bark plants. To prevent the emergence of weeds, a light geotextile felt proves to be 90% effective and allows to consume less water by preventing its evaporation. For rocky installations, stones can be recovered during the construction of houses, such as millstone in the soil of the Paris Basin ... Regarding the terraces, since it is difficult to control the origin of exotic wood, avoid use and prefer the ecological alternative of heat-treated wood.
Are there any tips for environmentally friendly landscaping?
If you have properly designed the landscaping of your ecological garden, it will not need water at all, except in the event of an extreme heat wave or for certain plants such as the fern. In this case, it is necessary to plan a sprinkling with recovery of rainwater. The ideal is to operate with a drip irrigation. Regarding fertilizer, the best is to have a compost bin. Do not hesitate to put these vegetable peelings and everything that is biodegradable. This manure will enrich the soil by creating effective topsoil over the long term. For those who do not have the space to install this silo, the horn and the dried blood, sold in shops, are very effective biological fertilizers.
A garden that evolves over time, according to the natural order, is it possible?
It is possible to create a moving garden if you create a flowery meadow made up of perennial plants: by sowing in zones, you can plan each year to make different passages. By mowing in one place, you can completely change your garden. To guide it a little and keep free spaces, it is enough to create a few zones of mineral coatings in the desired places.
