Have you ever noticed that the walls of a house with trees planted in a row or pots placed close to the wall often start to have greenish stains, algae or even black mold forming along the walls? Many people think this is normal for houses with gardens, but in reality, this is a warning sign that your house walls are accumulating moisture, which can cause the walls to deteriorate faster than they should.
The causes stem from several factors, including watering plants that seep back into the walls, insufficient ventilation due to pots blocking airflow, and wall surfaces that are not properly coated or painted for protection. When combined, these factors create a perfect breeding ground for mold and algae. This article will take you deep into why planting trees close to walls leads to mold and algae and how to professionally clean and paint walls to prevent the problem from recurring, along with tips on pot placement that help keep your home beautiful and the walls from deteriorating quickly.
Why do house walls have mold and algae?
1. Moisture accumulation from plant pots– When pots are placed close to the wall, the water used to water the plants seeps into the walls, causing moisture accumulation.
2. Insufficient ventilation– Plants block sunlight and wind, causing the walls to dry slower than normal.
3. Unprotected wall surfaces– If the walls are not painted with a primer or topcoat that has mold-resistant properties, the walls will deteriorate and have problems quickly.
