Practical nuances of growing perennials on the roof

To grow perennials on the roof in specially created flower beds, squares, beds or spots, care must be taken not only about the choice of plants.

First, the boundaries of flower beds and planting zones should be strictly limited: plants are planted only in the composition, created on the principle of raised beds or beds - rising above the general level of the roof.

Planning of the garden on the roof to think carefully, leaving enough room for a comfortable rest, movement, care of plants. Decorative paving, creating coverings, arrangement of seating areas, especially if the planned shading structures, complete before starting the gardening proper.

For the breakdown of flower beds with perennials on the roof will need to additionally lay its protective root insulating coating in the zone in which the object will be created. The protective coating is additionally covered with non-woven materials, and only then proceed to fill the actual structures. Wooden edging, plastic structures, fashionable portable modules are selected depending on the desired style and design concept. The bottom layer of flower beds create from drainage, which is mandatory for any stationary objects on the roof (with a layer of at least 10 cm). Drainage is covered with filtering fiber, and only then a layer of nutritious, high-quality, loose soil is poured, in which the plants will be planted.

Layer of substrate or fertile soil on flower beds on the roof directly determines not only the total weight of the entire structure and garden, but also what plants can be used. For succulents 5-7 cm of soil is enough, but other herbaceous plants will need more space and a layer of substrate with a thickness of 8 to 12 cm.

Additionally, the thickest layer of soil should be for lawns - about 15-20 cm. But such a layer of soil will allow to plant and cereals, and large, forming powerful roots perennials, and even decorative small shrubs.

For the creation of a garden on the roof use strong seedlings with a closed root system. Small dividers or plants with bare roots will take a long time to adapt and may die in specific climatic conditions. When selecting planting material it is important to pay attention to well developed roots, absence of traces of pests and diseases and active growth.
