Flower pot insert Prosperplast model PP-IWKO355, black, 18 L capacity

Prosperplast PP-IWKO355 is a black flower pot insert with an 18 L capacity designed to fit compatible planters. Suitable for both indoor and outdoor use, this lightweight insert provides a dedicated space for soil and plants while allowing easier planting, repotting and seasonal replacement. The insert helps contain moisture and soil, reduces mess during maintenance and can be combined with ventilated pots to support drainage and aeration for healthier roots.

Advantages

The insert is made from durable, weather-resistant plastic that tolerates everyday use and exposure to changing temperatures. Its standard shape and size make it quick to place into compatible planters, while the 18-litre capacity accommodates larger ornamental plants, mixed herb arrangements or multiple small specimens. The dark colour conceals soil marks and provides a neutral background for a variety of plant types.

How to use

Place the insert into a compatible planter so that it sits evenly and securely. Add a layer of drainage material if needed, then fill with potting mix to the desired level and plant. Water and maintain plants according to species requirements. For repotting or seasonal changes, lift the insert out to replace soil or move plants without disturbing the outer container. If combined with ventilated pots, ensure drainage openings align to allow excess water to escape.

Usage recommendations

For longer life, avoid direct prolonged exposure to intense UV when possible; use in shaded or partially shaded outdoor locations or bring indoors during extreme weather. Match the insert size to the outer planter to ensure a snug fit, and use appropriate potting soil and drainage layers for the selected plants.
