What is a large outdoor planter 100 cm?
A large outdoor planter 100 cm is an outdoor pot with a height or width of approximately 100 centimetres, designed for sturdy planting such as trees, shrubs or large ornamental plants. Due to its considerable dimensions, this tall outdoor planter offers sufficient space for root growth and a stable water supply.

Material and quality
A large outdoor planter 100 cm is often made from grade A corten steel or polyester, two materials known for their strength and weather resistance. Corten steel models develop a natural rust layer that protects against further corrosion, while polyester models are lightweight and resistant to frost, rain and UV radiation. Many models feature a folded top edge for extra sturdiness and internal reinforcement ribs against deformation. Some versions are available with or without a base and with or without feet, depending on the intended use.
Sizes and variants
Large outdoor planters 100 cm come in various shapes and finishes, from square to rectangular, and in different materials such as corten steel and polyester. Besides the 100 cm dimension, intermediate and alternative sizes are also available, so you can choose a planter that fits exactly the available space. Models are available with or without a base, with or without drainage holes and with or without feet. There's also plenty of choice in colour and finish, from the natural rust colour of corten steel to various RAL colours for polyester versions.

- Placing the pot on a surface that cannot support its weight
- Choosing the wrong size without considering the eventual size of the plant
- Not considering placement with or without a base on bare ground or paving
- Placing it too close to a wall, making maintenance of the back difficult
