Abstract

In a process used to constitute drainage devices at the bottom of gardening containers, it is known that the draining materials generally used are shards, gravel and loose sphagnum moss, in successive layers. In the present invention, it is made by an accessory serving as a substrate for draining and aerating the garden containers, it is a synthetic textile cushion, containing a permanently granular supply and, made of two synthetic materials including one of anti-root geotextile membrane and a synthetic fiber mesh, three component parts are cut in different shapes and sizes to constitute said cushion which must be either round, square and / or rectangular of different sizes depending on whether it is required. Adapting to various gardening containers on the market, this cushion acts as a dam to the soil and the roots of the plants grown in it and makes drainage more efficient and durable, resulting in a ready-to-use and reusable gardening accessory.

Description

DESCRIPTIVE MEMORY

The present invention relates to a gardening accessory used to drain and aerate all the containers to be gardened.

It is common practice in the case of a process for drain the bottom of the containers to garden to have to constitute drainage devices by depositing draining materials consecutive and successive layers; so that they do not collapse with the potting soil and then flee through the holes of drainage: are commonly used shards, gravel and sphagnum moss that holds the potting soil. We have to proceed with the removal when the roots come out, close the drainage holes in the container, and make it difficult to remove the motte; because they form a compact mass with the draining material, then the repotting of the plant is necessary, since it is necessary to proceed by unraveling the roots of these materials to retrieve or renew them. It is obviously necessary to have to perform several manipulations and provide for the materials to be used at each removal or repoting according to the next container, and it has been proposed to use a cushion of drainage and aeration of matter ready-to-use and reusable synthetic material which contains permanently a granular supply, this cushion is constituted

2/11 two component parts in an anti-geotextile membrane roots and a second component part, a fiber lattice which act as a dam to the soil and the roots; because this This type of process is not very effective during the growth, because roots obey geotropism in the restricted space of the containers and tend towards the layers of draining materials to amalgamate, seal and escape through drainage holes at the bottom of the containers to be which usually stagnates growth preventing water and the air to infiltrate the whole culture and, thus potting prematurely. I discovered that these disadvantages can be removed by the use of certain materials synthetic and the making of a rotproof cushion. Such so-called drainage and aeration cushion is reusable without loss of draining materials since it contains a supply granular material permanently retained between two of the said parts components, one of anti-root geotextile membrane and one fiber mesh, which allows for the implementation of spontaneous placement of a draining substrate and the elimination of process which consisted of disposing of the free layer materials and successive, and manipulations during the removal and repotting, because it is possible to easily remove the plant and its root ball of the container to note the development of roots in the soil, without having to undo and redo the device of

3/11 drainage and put the clod back into place to propitious time repotting if it does not take place. In addition, another component part fixed under the ventilation mesh, which she also composed of an anti-root geotextile membrane prevent the roots from passing under such a drainage cushion and aeration; equipped with three component parts that force plant roots to settle in the soil instead of invade the granular supply and stagnate at the bottom closed containers and, which favors with said lattice aeration air infiltration into the whole culture as well irrigation water to flow unhindered during the growth period.

7/11 The illustrated accessory has three components in form layers that must be cut and assembled in order as shown in fig. ( AT ). A component part (1) being the upper layer forming the top of the cushion consisting of a anti-root geotextile membrane, this fixed component part on a trellis of synthetic fiber, component part (2) being the layer forming the bottom of the cushion fixed with a seam (6) = fig. (B) thus assembled, the component part (1) is called the anti-root membrane and the piece component (2) is the ventilation mesh which form a so-called protective envelope (0) = fig. (C) in which is introduces a granular supply (4) and so it is contained permanently, another component part (3) = fig. (A) is an anti-root geotextile membrane ring, it is fixed under the ventilation mesh (2) = fig. (D) likewise by another sewing (7) to form after assembly of said component parts a semi-rigid and flat crown (5) =
Fig. (E) located on the perimeter of the cushion. For example fig.
(F) a container for gardening (8) is placed in a saucer of recovery (it) inside which one voices the openings of drainage (9) from which an excess of water can come out and a potting soil (10) is supported by all of said component parts fig.
(F) an accessory including an anti-root membrane, which makes as a dam on the soil and, (with roots not shown). The

8/11 semi-rigid crown (5) = fig. (F) also serves as dam potting soil (10) and the roots that prevent them from escaping drainage holes (9), the ventilation mesh (2) and the anti-root membrane (1 retain, ventilate and protect the granular supply (4).

In order to adapt certain kinds of plants to the whole of culture; the drainage and aeration cushion placed at the bottom of the container (8) can be used, if desired or necessary, as a sensor capillary to keep the soil moist without the roots bathe in the water of the salvage saucer (11); or again, in another case, it may be made use of a second cushion (not illustrated) that is available in the saucer of recovery (11) to serve as a drainer to the container and avoid that he is constantly bathing in the water, which makes it possible to obtain optimal ventilation without having to empty the saucer recovery (11) = fig. (F) at each watering.
