Watering the soil - the most important link in the care of a greenhouse plant. In case of temporary impossibility of regular manual irrigation of the land, they come to the rescue laws of physics and improvised means.

Moistening the soil using a dug-in plastic bottle - ideal alternative to watering in the usual way.

How to organize watering?

If a the air in the greenhouse is dry and hot, then in order to organize watering with the help of dug-in plastic bottles, for each plant from the greenhouse you will need 1 liter and a half.

When moderate humidity and temperature it is advisable to use soil 1 bottle for 2-3 plants.

For irrigation hygrophilous or large greenhouse residents use 3-5 liter containers.

1 way "down the neck"

  1. Use a needle to poke a series of small holes in the narrow part of the bottle near the neck. The number of vertical rows of holes should correspond to the number of plants being watered.
  2. Cut off the bottom.
  3. Wrap the bottle in a cotton cloth to prevent soil particles from clogging the holes.
  4. Dig a hole 10-15 cm deep between the plant roots.
  5. Place the homemade sprinkler with the lid closed with the neck down, point the holes towards the root system.
  6. Cover the bottle with earth, fill to the top with water for irrigation and cover the bottom with a plastic lid to reduce evaporation of the liquid.

Don't make big punctureswith a diameter greater than the thickness of the needle. Through them, the water will leave the container early, due to which the plant may suffer from dehydration.

Important... Do not use containers from under aggressive liquids (solvents, glass cleaner) and oils. Residues of these substances on the walls of the bottle pollute the soil and have a detrimental effect on plants.

2 way "upside down"

It differs from the above method by the absence of the need to cut the bottom of the container. Holes are being made with an indent from the bottom by 2-3 cm.

If the bottle runs out of water ahead of time, the liquid remaining at the bottom will be able to compensate for the lack of moisture for some time.

Bury the bottle in the soil up to the neck... Cover the neck, but do not tighten the plugso that the container does not shrink as it is emptied.

Interesting... Application of this method provides longer irrigation period due to the available "reserve" of liquid at the bottom and a smaller area of ​​moisture evaporation through the neck.

How does the method work?

Irrigation with bottles dug in the ground is based on moving liquid from a more humid environment to a drier one, that is, along the moisture gradient. Speed ​​up the process contributes to the gravity of the water.

When the ground is saturated with moisture, the flow of water from the bottle slows down by flattening the gradient.

With this method the likelihood of overdrying or excessive soil moisture is minimized.

Benefits of bottle irrigation

  1. Undoubted cheapness thanks to the use of improvised material in the manufacture of the sprinkler.
  2. Simple and fast application of the design.
  3. Save time... The need for frequent visits to the greenhouse to check soil moisture disappears.
  4. Through the bottle, it can enter the ground not only water, but also fertilizers dissolved in it... They are dosed and directly to the root system, bypassing the overlying soil layers.
  5. Reliability: Now you do not have to worry about the condition of the plants during a short-term departure.
  6. Prevention of fungal diseases root system caused by excessive soil moisture.
  7. The need disappears loosening and softening the earth.
  8. Waterin a container dug into the ground reaches the ambient temperature and warmed up comes to the roots.

What crops can be watered?

The drip irrigation method is suitable for plants with aerial shoots and fibrous root system:

  • cucumbers;
  • tomatoes;
  • cabbage;
  • pepper;
  • eggplant.

Warning... The method is not suitable for root crops (carrots, beets, turnips). If you are using plastic bottles for greenhouse watering, manual watering cannot be completely ruled out due to the fact that leaf irrigation procedures play an important role for many plants.

Useful and inexpensive

Many experienced summer residents use self-made irrigation systems and prefer them to factory ones. Do not rush to throw away old plastic water bottles, because often modern methods have cheaper analogues.
