The space between pavers is an extreme location when it comes to planting. Temperatures here are hot, leading to drought. Stress also plays an important role that you need to consider when choosing plants.
A bit of green between the joints makes the pavers look much more natural
preparations
Knives and tools with spikes or scrapers will help you to remove the weed growth between the stones. They are effective against mosses that have not developed a deep root system. A more convenient and effective method is electric grout cleaners, which can be expensive. The middle choices are high-pressure cleaners (€119.90) and flame-flame devices, but you have to pay attention to the material durability.
fill up soil
After the unwanted growth has been completely removed, fill the gaps with a loose soil mixture. Some sand increases permeability. There are special mixtures on the market called roof garden soil that are suitable as filling material.
planting
In order for the plants to grow well, the joint width should not be too narrow. Seed mixtures of annual and perennial herbs are recommended for joints of less than two centimetres. These should be sturdy and durable. Wide gaps offer space for flat-growing cushion perennials.
Planting ideas for paving joints
- cushion plants: star moss, houseleek, cat's foot and stonecrop
- ground cover: Pennywort, Woolly Thyme and Prickly Nuts
- drought indicator: Hunger flowers, stone quenelle and pearlwort
- grasses: Bluegrass, Bearskin Fescue and Bermuda Grass
What to look out for
Most species don't turn out to be tough, so their hearts must lie protected in a deeper level. Roman chamomile and prunella are exceptions, exuding a sensual scent when treaded on. Nevertheless, these plants should not be planted between heavily used paving stones.
benefits
Herbs bring color to the overall picture and enrich the diversity of species. Flowering herbs attract wild bees, bumblebees and butterflies. The functional benefit of such a green roof should not be neglected. Joint planting ensures that unwanted species such as moss and root weeds have no chance of growing.
maintenance
In the first few weeks after sowing seed mixtures, you need to take care of regular watering. Reseeding may be necessary if not all seeds have sprout. Once the growths are firmly established, they don't require any special attention. They develop a natural look over time and can be trimmed back if necessary.
