A garden wall also becomes dirty over time. Mosses, lichens and algae are settling and the masonry looks run down. If this is desired, the mossy structure can give the garden a romantic, morbid charm. However, such a wall usually just looks unkempt and should be cleaned thoroughly. You can find out how to do this here.
How to effectively clean a garden wall?
To clean a dirty garden wall, you can use a high-pressure cleaner, water and brush or special cleaning products such as green algae remover and natural stone cleaner. Home remedies such as vinegar and cola are not recommended; soft soap can be used instead.
Cleaning with the high-pressure cleaner
This is very simple and quickly leads to clean success. When doing this, aim the rotating head of the high-pressure cleaner as vertically as possible towards the wall. If necessary, reduce the pressure, for example with dry stone walls, so that the joints are not washed out.
However, this method is suitable for
- sensitive joints,
- planted natural stone walls
- Walls with ornamental plants growing at their base
only to a limited extent.
Clean the garden wall with water and a brush
Cleaning with a hard brush is a little more physically demanding, but significantly gentler on the small structure. If you use warm water, moss and algae can also be easily removed.
You can also use green algae removers. However, please note:
- The substrate should be dry so that the product is not unnecessarily diluted.
- Apply the preparation with a garden sprayer (€27.00 on Amazon). This means it can be dosed precisely and only applied where there is actually deposits.
- Green algae removers are highly effective pesticides. Only use these where the substances cannot affect the growth of plants.
A special natural stone cleaner is recommended for a natural stone wall. This is pH-neutral and does not attack the sensitive stone. Most of the time, the products are harmless to the environment and nature. However, you should use them sparingly and exactly according to the manufacturer's instructions. Since the cleaners have to work for several days in dry weather conditions, you should keep an eye on the weather forecast before use.
Are home remedies like cola and vinegar helpful?
Especially if you want to use vinegar water to clean the garden wall, you are entering a legal gray area. Depending on the product used, this also applies to other home remedies. That's why it's advisable to stay away from these.
Tip
If you want to take environmentally friendly action against green deposits on the garden wall, you can scrub them off with soft soap. To do this, prepare a saturated soap and water solution and brush off the dirt thoroughly.
