Why and when does the zinc tub need drainage?
The drainage ensures that excess irrigation and rainwater can drain away. Almost all plants are very sensitive to waterlogging and once the roots have rotten, the plants can no longer be saved.
Therefore, drainage is always necessary when the water supply cannot be controlled, as is the case outdoors. A planted zinc tub that stands outdoors without a roof therefore always needs drainage.

When does a zinc tub not need drainage holes?
You can do without the drainage holes if the zinc tub is covered or in the apartment. However, you should also provide a drainage layer made of expanded clay (€ 17.50 on Amazon *) or granules, where excess irrigation water can temporarily "store". It is also important that you pour a zinc tub without holes only moderately.
Make holes without a drill
If you don't have a drill on hand, you can try to get the holes into the ground differently. For example, you can try pounding holes in the ground with a pointed nail and hammer. But be careful!
How big should the drainage holes be?
In a zinc tub you should drill several well spaced drainage holes about the size of a fingernail. These are covered with pottery shards or drainage fleece so that they cannot clog.
The zinc tub without holes as a pond
Your zinc tub has no holes? Perfect! Then take advantage of the fact that it is completely waterproof and plant it as a mini pond instead! Proceed as follows:
- Put your zinc tub in its final location.
- Create multiple levels using large stones and inverted planters.
- Then place the aquatic plants in plant baskets where you want them and secure them with stones.
- Fill the zinc tub with water.
- Finally, place floating plants and decorative elements.
