If it was discovered that the soil in the greenhouse turned green, it means that the climate was malformed, and appeared uninvited guests - mosses and algae. They may look impressive, but it is a weed, which will have to deal ruthlessly.

What causes moss and algae
These species of flora settle with excess moisture, but there are other reasons:
- insufficient air exchange in a fertile bed;
- too much phosphorus;
- stagnant air.
Soil purification steps
First you need to determine what kind of soil parasites settled in the greenhouse.
mosses
Moss is determined at once - it's lush velvety carpet of bright colors can be grassy or even emerald.
A soft, friable, does not form a dense root layer - if you take it in hand, he immediately falls apart. It can be easily removed from the soil.
Seaweed
Are a huge number of small organisms that can create on the soil surface of the plaque.
In rare winding coupled with copious irrigation usually appear both species of parasites. If they could see in one place, it is necessary to examine all the greenhouse, because they are populated by all suitable surface.
What to do with a carpet of moss
Able to grow deep. After removal of growth areas, it has not recovered, it is necessary to remove the shade and watered only greenhouse crops.
But it can not solve the problem completely, as spores are able to sleep for a long time waiting for external conditions improve.
Warn them you need to reactivate the following actions:
- thorough cleaning of the greenhouse (you need to make all that can be shaded place for moss growth);
- adding light (for illumination shaded areas foil is used);
- moss removal from all parts of the structure (wood parts cleaned with ferrous sulphate solution, the stone of the foundation shuttering and - soda solution);
- fresh air (airing is necessary so that there are no drafts, not to harm the cultivated crops);
- Bordeaux liquid soil treatment guaranteed to deliver the soil from microorganisms (commercially available ready mix or make prescription independently);
- sowing green manure (there are a lot of fast-growing crops that improve its soil composition, for example, mustard).
In a pinch, you can use chemicals or replace the ground completely.
What to do with algae
Algae prefer light. Therefore, their growth is suppressed by mulching (suitable sawdust, straw, bark, sand or vermiculite).
In the greenhouse, may appear and lichens, but simple measures are not removed - it is necessary to constantly monitor the condition of the ground and structures and scrape them manually. But this is not very onerous - the lichens grow slowly.
preventive measures
Should think about this at the time of installation of greenhouses - select a location on a hill, well lit by the sun.
No need to pour the entire surface in the greenhouse - drip mounted under each plant, save water and exclude excess moisture.
The air should be fresh - it is arranged multilevel ventilation, forced ventilation.
From an excess of phosphorus is difficult to get rid of, he can only return to normal over time - it is necessary to periodically clean the soil from pests until his number is not normalized.
To preserve the optimal composition of topsoil, it is desirable to follow the rules of crop rotation - alter plants places punctuate planting permanent greenhouse crops with fast-growing plants, regularly and dig to enrich the land.
