The tips that matter
- The whole plant is TOXIC: gloves for pruning, and no leaves or branches near children, pets or livestock.
- It flowers on the current year's wood: prune in late winter or after bloom, never in spring.
- In summer it drinks enormously: a thirsty potted oleander stops flowering on the spot.
