If a flower box does not have a rain cover or is protected by a canopy, the water will be up to the edge after heavy rain. Read here how you can act correctly now and effectively prevent the dilemma.
What to do if the flower box is overflowing after rain?
To empty a flower box full of water and prevent it from being removed in the future, you should remove the plants, pour out the box, drill additional holes, insert a drainage layer and a breathable fleece and finally fill in new substrate.
Remove and prevent waterlogging - this is how it works
If your balcony box looks like a miniature swamp landscape after every rainstorm, here's how to repair the damage:
- Unpot all plants and remove the wet substrate
- Pour out the flower box and remove the soil
- Drill several holes in the ground
- Spread a 3-5 cm thick layer of grit, pottery shards or expanded clay (€19.00 at Amazon) over the holes
So that the drainage made of inorganic material does not become muddy with plant soil, place a breathable fleece over it. Now fill the balcony box with fresh substrate and place the plants in it. In this exceptional case, please wait a few days before watering for the first time so that the excess water in the roots is reduced.
