Hard Landscaping is all about the non-plant part of your garden.

This includes all walling and paving, pergolas, fencing, water features and many other items as long as they doesn't grow.

Gravel can be used to cover the ground here in Cyprus to try to prevent weed growth.
It may sound a bit silly but as soon as the ground gets some water and sunlight the plant seeds germinate.

They are not fussy and all types of fauna will spring up everywhere.

Under most circumstances this rainfall or irrigated water is a blessing and it will help your plants no end. Unfortunately there are other less desirable plant seeds lurking in the soil, and as soon as they get wet coupled with the heat they will spring up.
