A potted oleander needs suitable light and drainage, with winter shelter chosen according to local temperatures and the plant's condition. Check the root ball before watering a plant kept in a cool sheltered position.
A bright site and a substantial pot
Oleander needs strong light and enough space for its woody growth. Use a stable container with drainage, allowing access for watering and moving under protection where the climate requires it.
Water according to growth
A leafy oleander in warm conditions can use water quickly. Check the root ball rather than assuming drought tolerance means never watering. Let drainage escape instead of leaving the plant permanently submerged in an outer vessel.
Pruning changes the display
Remove dead or damaged growth and shape only as needed. Cutting many shoots back can remove the next flowers, so choose timing from the plant's growth and local conditions. Use a suitable feed during active growth rather than increasing concentration to force buds.
Handle it as an ornamental
Oleander plant material is toxic. Use appropriate protection when pruning, keep cuttings away from food and do not burn or use the wood for cooking. Protect a potted plant from freezing and check species-specific winter guidance; a sunny summer display does not establish winter hardiness.
