Many people know that because of the overflow, plants can rot and even die. In order to avoid such an unpleasant outcome, plants it is necessary to provide high-quality drainage for flowers even when planting. For drainage, gravel, expanded clay, crushed stone, broken brick, polystyrene, moss, charcoal, etc. are actively used. Next, we will consider in more detail the characteristics of certain drainage components.
Gravel and crushed stone
The main disadvantage of this drainage is too much weight. For example, a ceramic pot with gravel will be very heavy.
Expanded clay is a burnt clay with a porous structure. This material can be of different fractions. The advantage of expanded clay is that it is very light. In addition, expanded clay perfectly retains moisture.
The water-holding ability allows expanded clay to absorb excess moisture (caused by excessive watering), and in dry weather - to give moisture to the root system of plants.
Calcined clay has a neutral pH and does not degrade over time.
Expanded clay is most often used for 5-6 years. After this period, the material begins to be converted into soil.
Bricks are made of clay and various additives that improve certain characteristics of the material. After manufacturing, the brick is fired.
Brick has a pronounced ability to absorb moisture. The main disadvantage of broken brick is that the sharp edges of such drainage can damage the roots of plants.
Some summer residents make drainage from ceramic shards. The main disadvantages of the material are that ceramic shards can not always be at hand, and when transplanting plants into a large capacity, broken shards damage the delicate roots of plants.
Styrofoam is also used as drainage. Its advantage is that it is free and always at hand. This material is very light, so it is convenient to use in heavy ceramic pots. Polyfoam allows excess water to drain onto a pallet, which protects the roots of plants from decay.
The disadvantage of polystyrene is that the roots easily sprout through it. The foam is used as follows: it is cut into small pieces and put in a ceramic pot. The foam drainage layer should be 2 cm.
Charcoal is considered to be a highly effective antiseptic and natural fertilizer. It is able not only to prevent the process of decay, but also to adsorb salts, regulate soil moisture.
Coal effectively absorbs minerals and water, and then, as the soil dries, gives them to the plant. This type of drainage is neutral, porous, inert and light. Charcoal is used as follows: a thin layer is laid at the bottom of the pot, the height of which does not exceed 2 cm.
Some summer residents use pure sphagnum moss as drainage. It perfectly retains moisture and gives it to the root system as needed. In addition, moss has disinfecting and healing properties.
