Terracotta or plastic? When choosing the right pot, the appearance should not be decisive. An overview of the advantages and disadvantages of different planters.

by Helge Masch

Container plants are popular in the garden as well as on the terrace and balcony. When choosing a planter, however, optics should not be the sole criterion, because the material is particularly important for good growth of the plants.

Plastic Bucket: Lightweight, but has a limited shelf life

Plastic buckets offer many advantages. They are light and the material prevents water from evaporating quickly. These pots are therefore ideal for citrus plants: there is no evaporation cooling near the sensitive roots. Repotting plastic tubs is uncomplicated: since the roots do not adhere to the smooth surface, no roots can tear off and damage sensitive plants. However, the shelf life of plastic tubs is limited, because sunlight makes them easily brittle.

Terracotta bucket and clay pot: durable but heavy

Terracotta buckets are very nice, but quite heavy.

Terracotta and clay pots can be kept for many years, but depending on their size, they can also be difficult to transport. If the vessels are not painted, water will escape through the porous structure. The water evaporates on the outer wall and leaves unsightly white limescale stains or mosses and lichens develop, so the pots have to be cleaned regularly.

tip: It is best to plant the plants in a plastic pot and place it in a terracotta tub. The plants can be transported more easily and there is no deposit on the terracotta pot.

It is better not to plant zinc tubs directly

Zinc containers are also long-lasting and light. Depending on the weather, zinc can, however, decompose, pass into the earth and then be absorbed by the plants. The result: the plants can die. Plastic or pond liner in the tub protects the plants. Wicker baskets should also be lined with foil or, even better, only serve as a planter, as the natural product is also damaged by permanent moisture.

Buckets made of larch wood have a shelf life of around ten years, but above a certain size they can hardly be transported due to their heavy weight.

The right fertilizer for Potted plants

Fertilizer is particularly important for container plants because they cannot draw their nutrients from the garden soil.

Container plants thrive particularly well in high-quality substrate. Mineral fertilizers are particularly recommended for the supply of nutrients, as the plants can absorb them directly. So-called synthetic resin-coated fertilizers are more expensive than conventional ones, but they have an excellent effect. These fertilizers usually have the expression "cote" in their name and work for up to six months, so they only need one application per season.
