A maintenance-free garden
This is THE big advantage of a gravel garden, it requires almost no maintenance. The gravel being laid on a layer of geotextile, the weeds do not grow, or very little. Indeed, they are not able to grow without light and exceed the geotextile and the thickness of the gravel. In addition, the selected plants are generally easy to maintain since they grow naturally in a stony substrate.
100% gravel or pebbles
Gravel or pebbles are used for a massif, for a border or for a driveway. It is quite possible to design a garden that is easy to maintain and very mineral. There is a gravel bed at the foot of the plants in the beds, a line of gravel to delimit the spaces or even paths lined with gravel. Either way, you have to start by preparing the ground!
Step 1: prepare the ground
Start by delimiting your massif or your driveway. The tricky part is removing the weeds. To make it easier for you, spread a tarp over the entire surface of your future gravel bed.
Without light, spontaneous herbs will no longer grow. After 2-3 weeks, remove the tarp and remove the residue. Then pass a stroke of the rake to level the ground which must be flat. If your soil is heavy, now is the time to cut it with sand 40cm deep. No need to add compost which could stimulate the emergence of weeds.
Step 2: geotextile layer
It's time to unroll your layer of geotextile, so that it covers the extent of your bed or driveway.
So that your driveway or your bed is not overgrown with surrounding grasses, take care of it. delimit with a border.
Metal blade, logs, bamboo, paving stones ... The border is the finish of your bed! In addition, it will prevent gravel from escaping.
Step 3: the choice of plants
Which plants to choose for landscaping the garden with gravel? We take inspiration from natural mineral landscapes to select plants. In the vegetal palette of alpine plants you can opt for phloxes, bellflowers and gentians.
Mediterranean plants are also suitable, such as lavender, thyme or santolina. You can be tempted by exotic plants if your soil is dry. Agaves and cacti will be perfectly comfortable in this environment.
On the shrub side, sea buckthorn or Grevillea are well suited to growing on gravel.
Also consider grasses which are not very demanding in terms of soil. Vary the colors with Miscanthus, fescues and stipas.
Step 4: planting
Once you have chosen your plants, you have to choose where to place them. The best is still to have an overview by arranging them as you wish on the geotextile. Adjust the locations, taking care to respect the planting distances and that you can see all your plants. When you are satisfied with the result, make a cross cut in the geotextile under each plant. All you have to do is dig and plant your plants. Remember to water right after planting for good rooting.
Step 5: the choice and quantity of stones
White pebbles, gray or beige gravel, there are many colors available. Choose a grain size between 5mm and 10mm depending on the desired style. The gravel layer should be about 5cm to 7cm high.
- Depending on the gravel chosen and the thickness, it takes between 100kg and 150kg of gravel per m2.
Step 6: spread the pebbles, gravel
That's it ! Your massif and driveway are ready to be covered with gravel. Take it slowly so as not to damage the plants. Use a rake to distribute the pebbles and obtain a very flat and homogeneous bed.
Maintenance will then be very limited: a few weeds to pull out, remove the plant debris and rake from time to time.
