Overview

• Garden outlets advise moving oleander into frost-free quarters before the first cold nights arrive.
• Autumn pruning should be limited to about one-third of the plant, stopping at the first visible bud on each shoot.
• Gloves are recommended during cutting because the plant’s sap is poisonous and can irritate skin.
• Overwinter in a bright, cool spot around 5–10 °C with very little watering, no fertilizer, and occasional leaf misting to deter spider mites.
• A radical rejuvenation cut to 10–30 cm is reserved for weakened or heavily infested plants and typically results in a flowerless year before stronger regrowth.
