Practical nuances of growing perennials on the roof
To grow perennials on the roof in specially created flower beds, discounts, beds or spots, you need to take care not only about the choice of plants.
Firstly, the borders of the flower garden and planting zones must be strictly limited: plants are planted only in compositions created on the principle of raised beds or beds - towering above the general level of the roof.
The layout of the roof garden needs to be carefully thought out, leaving enough space for a comfortable stay, movement, and plant care. Decorative paving, the creation of coatings, the arrangement of recreation areas, especially if shading structures are planned, are completed before proceeding with the actual landscaping.
To break down flower beds with perennials on the roof, it will be necessary to additionally line it with a protective root insulation coating in the area within which the object will be created. The protective coating is additionally covered with non-woven materials, and only then they begin to fill the structures themselves. Wooden borders, plastic structures, fashionable portable modules are selected depending on the desired style and design concept.
Finished "frames" are filled with several layers of substrate. The lower layer of flower beds is created from drainage, which is mandatory for any stationary objects on the roof (with a layer of at least 10 cm).
