Drainage hole and drainage in the flower pot
The drainage hole in the flower pot is necessary so that excess irrigation or rainwater can drain away. If the water builds up in the pot, waterlogging occurs, which leads to root rot.
Flower pots and pots in the garden should always have a drain, as they have to cope with heavy rain every now and then.

Drainage is useful in flower pots and pots, as too much water can run off here, but a certain amount of residual moisture remains in the pot and the plant can use it on dry days. A drainage usually consists of expanded clay, (17.50 € at Amazon *) gravel or potsherds, which is covered with a piece of fleece so that it cannot mix with potting soil.
Pots and planters without holes
With indoor plants you can do without a drainage hole in the pot if there is a generous drainage layer. If watered moderately, the drainage can absorb the water well and slowly release it to the plant. If you want to be absolutely sure, you can always see how much water is left in the pot with an integrated irrigation system (€ 69.29 at Amazon *).
Create a water reservoir
A pot with a water reservoir can be made from a plant pot without a hole.
- Draw an auxiliary line around 5 cm from the bottom of the pot with a pencil (the height of the line is variable depending on the pot size).
- Put the pot on its side.
- Have a second person hold on to prevent the pot from rolling away.
- Clamp a thin drill bit in drill press. (€ 43.99 at Amazon *)
- Carefully drill several holes on the drawn line.
- Then re-drill with a stronger drill.
Now fill a drainage layer in the pot, the upper limit is the row of holes. Now you can insert a plant and pour enough water over it until it comes out of the holes. You now have a water reservoir from which the plant can supply itself with water for several days.
