1. Placement and surface

Ensure a stable and level surface when placing a planter.

When used on a terrace or balcony, it is important to check in advance that the weight of the filled planter (soil, plants and water) does not cause any structural load.

Note: a bottomless planter is not suitable for use on a balcony or terrace, as water and soil can flow out freely. When placing a bottomless planter, make sure its sits on a stable, level and well-draining surface such as soil or gravel. This prevents sinking and ensures that excess water can drain away properly.

2. Drainage

Cortori planters with bottom are fitted with drainage holes as standard. For optimal water management, a proper filling structure is essential.

Start with a 10-20 cm drainage layer at the bottom, using for example clay pebbles, lava stone, or crushed rubble. Place a permeable root cloth on top to prevent soil from sinking into the drainage layer and blocking water flow.

Tip: Ideally place the planter on legs or wheels. This improves drainage underneath the planter and prevents moisture build-up or staining on the surface.

3. Filling the planter

A correct filling method is essential for healthy root growth and proper water balance. This prevents both waterlogging and dehydration:

• If you choose a planter with bottom, start with a 10-20 cm drainage layer (see above), then place a root cloth.
• Choose a light, well-draining potting soil suitable for plants (e.g. acidic soil for rhododendrons.
• Optionally add extra compost or fertiliser, depending on the plant species. 

4. Additional tips

• Pay attention to the planter depth: allow at least 30-40 cm for perennials or shrubs, 50-60 cm for small trees, so the roots have enough room to grow.
• Consider an automated drip irrigation system if the planter is large or difficult to reach for watering.
• Mulch the top with bark or gravel to reduce evaporation.
