What is a hydrogel for plants and how to use it


One of the main conditions for the normal development of indoor plants and flowers is a sufficient level of soil moisture. To control this issue with a busy work schedule is quite difficult, so you have to try different ways. In fact, this issue is much easier to solve, you just have to buy a hydrogel and learn how to use it.

What is a hydrogel for flowers?

Hydrogel is a non-toxic polymeric material having the ability to absorb a large amount of moisture (irrigation water or mortar with fertilizer) and hold it for a long time. Due to the unique property of the polymer, timely feeding of the root system occurs.

Available hydrogel in the form of granules, which retain their qualities in a wide range of temperatures. Over time, the product loses its properties and decomposes into safe substances. You can buy it in almost any garden store or via the Internet.

Types of gel soils for plants

There are two modifications of the hydrogel, which have different structure and purpose.

  • Soft polymer it is intended for entry into the soil of indoor plants in order to increase the inter-irrigation period, rooting of cuttings and for seed germination. Gentle structure does not interfere with root processes. Means, absorbing a large amount of water, prevents souring of the soil from plentiful watering. Flower roots easily penetrate into the polymer material and are fed from it for a long time.
  • Dense decorative polymer (aquagrunt) is used to create compositions. It has a multi-colored color with an incredible brilliance, made in the form of balls, cubes, pyramids. Transparent vessels fill with aqua-ground to form layers of different colors. In such a substrate, the cuttings rooted perfectly, the cut flowers delight the eye for a long time. It should be noted that harmful bacteria do not breed in the polymer, the formation of midges is excluded.

Pros and cons of using akvagrunta

Flower growers have already managed to fully appreciate the benefits of using a hydrogel for indoor plants. Among the main advantages:

  • high rate of absorption (1 g of dry granules absorb 200-300 ml of liquid),
  • favorable conditions are created for the nutrition of indoor crops,
  • the soil is not overmoistened, which excludes the formation of fungal diseases,
  • prevents the leaching of beneficial substances
  • the flowability of sandy soil decreases, and the clay becomes looser,
  • microbiological processes in the soil are excluded,
  • reducing the consumption of expensive water-soluble fertilizers.

Like any garden product, hydrogel has cons:

  • they are not recommended to fill a transparent pot; granules are blooming from sunlight exposure,
  • hydrogel gel balls will not be able to provide adequate nutrition, fertilizers can not do,
  • it is rational to use the product one-time because of the peculiarity of losing unique qualities over time.

How to use the tool?

Before use, the acquired granules should be soaked in water.. According to the instructions on a 3-liter jar you need to add 2 tablespoons of hydrogel. After moisture absorption (after 10-12 hours), the granules significantly increase in size. The remaining water needs to be drained while holding the gel in a colander.

To plant a plant, you need to mix the substrate with a hydrogel in the ratio of 3: 1 or 5: 1 (according to the attached instruction) and fill the pot with the mixture. Liberally watered at first, the plant should not be, a sufficient amount of moisture is in the polymer material.

Miracles in hydrogel

For rooting cuttings, it is enough to fill the container with soaked gel balls and place the sprout in the center. In this case, it is not necessary to mix the soaked crystals with the ground.

How to store?

The gel, which could not be used, can be stored in a cool place. For this ideal refrigerator door. The main requirement is that the container is tightly closed. If you leave the jar open, the granules crystallize due to evaporation of moisture. They can also be used after re-soaking. The shelf life of the finished gel is 1-2 months.

Each plant has its own watering schedule. When the soil is enriched with hydrogel, the intervals between irrigation increase by at least 2 times. But for accurate timing you need to watch the petals first time. If there is a slight sign of wilting, urgent irrigation measures are needed.
