Oleander is a hardy, beautiful evergreen shrub with colorful flowers. Pruning keeps it healthy, encourages growth, and helps shape it into the desired form.
1. Annual Pruning
- When: Late summer or early fall, after flowering. Avoid pruning past October to prevent winter damage.
- Tools & Safety:
- Wear gloves (oleander sap is toxic and can irritate skin).
- Use sharp gardening shears.
- Steps:
- Remove new shoots at the base (suckers) to redirect energy to the main plant.
- Trim stems to half the height you want the plant to grow. Example: Cut to 2 feet if you want a 4-foot-tall plant.
- Shape the plant by trimming overhanging or scraggly branches just above leaf nodes to promote flowering.
2. Removing Dead Growths
- When: Monthly, or as needed.
- Tools & Safety:
- Wear gloves and consider long sleeves for protection.
- Steps:
- Inspect the plant for dead or damaged branches from all sides.
- Trim damaged branches a few inches below the affected area.
- Cut entire damaged stalks close to the roots if necessary. The plant will regrow healthier.
3. Finishing Pruning
- Fertilize: Use a nitrogen-based fertilizer to support regrowth.
- Water: Lightly water the plant after pruning but avoid overwatering.
- Dispose of Cuttings: Bag and discard safely (don’t compost—oleander is toxic).
- Clean Tools & Wash Hands: Wash shears and exposed skin thoroughly after pruning.
Tips for Healthy Oleanders:
- Heavily prune old plants to encourage bushier growth.
- For a tree-like shape, remove lower branches near the base.
- Avoid pruning if the plant looks healthy and the size is manageable.
Warnings:
- Oleander is poisonous—keep cuttings away from children and pets.
- Seek immediate medical attention if ingested.
