Let your greenhouse floor become like a beach
Greenhouse floors can vary. Some prefer an aisle with beds along the sides. Some put in wooden floors, others put in tiles. Tiles and wooden floors have some disadvantages, but they can be fixed. A greenhouse is at times a humid environment. This means that algae quickly will get going on the floor. A wooden floor can get slippery, while tiles will lose their charm if they get too infested with green algae.
Sand between your toes
The solution is easy. Sprinkle sea sand on the floor when the season starts or in autumn. If you do it in autumn, you can just sweep it off next spring. The floor will then be clean. If you do it in spring, you should not expect your floor to get back to normal until in a few months.
Maybe you’ll find the sand floor to be comfortable. It is in many ways practical, as it quickly absorbs spilt water.
If the sand gets too dirty, sweep it up and change it. A heavy loam soil would benefit from the sand. Of course, it can be a bit salty if not washed, so spread it or wash it through. You can also put the sand in beds with goutweed, they don’t like that. Another advantage is that ants don’t like sea sand, so if they are a plague in your greenhouse, this might be a great way to get rid of them in a natural way.
