V. Are Oleander plants toxic?

2. Cuttings – Take 6-8 inch cuttings from healthy Oleander plants in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone before planting it in a pot with well-draining soil. Keep the soil moist and warm until roots develop, then transplant the cutting to a larger container or garden bed.
3. Division – Divide mature Oleander plants in the spring by carefully separating the root ball into smaller sections. Replant each section in a new location and water thoroughly to help them establish.
Overall, Oleander plants are a beautiful addition to any garden or landscape, but it is important to be aware of their toxic nature and take precautions when handling them. With proper care and attention, Oleander plants can thrive and provide years of enjoyment with their colorful flowers and lush foliage.
