Light Requirements:

Nerium oleander "Double Yellow" thrives in full sun. For the best flower production, ensure the plant receives 6 to 8 hours of direct sunlight per day. While it can tolerate partial shade, too little sun will reduce the number of blooms.

Soil:

Oleanders are adaptable to a wide variety of soils, but they perform best in well-draining, moderately fertile soil. They can tolerate sandy, loamy, or even poor soil conditions. Ideally, the soil should be slightly alkaline to neutral (pH 6.5–7.5). Amend with compost or organic matter for better growth if the soil is low in nutrients.

Watering:

Oleanders are drought-tolerant once established, but regular watering will ensure healthier growth and better blooms. Water deeply when the top 1 to 2 inches of soil feels dry, especially during hot or dry periods. Avoid overwatering, as soggy soil can lead to root rot. It’s better to let the soil dry out slightly between watering sessions.

Temperature and Humidity:

Nerium oleander "Double Yellow" is hardy in USDA zones 8–11 and can tolerate temperatures down to 15°F (-9°C). In colder climates, it's best to grow the plant in a container so it can be moved indoors during winter months. This plant prefers warm, dry conditions and can tolerate low humidity once established.

Fertilization:

Fertilize the plant in spring with a balanced, slow-release fertilizer to encourage vibrant blooms and healthy growth. If desired, feed again in mid-summer with a light application to maintain its strength. Avoid over-fertilizing, as it can result in excessive leafy growth with fewer flowers.

Pruning:

Prune in late winter or early spring to shape the plant and remove dead, damaged, or leggy stems. Regular pruning will help control the size of Nerium oleander and encourage bushier, more compact growth. You can also deadhead spent flowers throughout the season to promote continuous blooming.

Propagation:

Nerium oleander "Double Yellow" can be propagated by semi-hardwood cuttings taken in late spring or summer. Place the cuttings in water or soil to root. Seeds are also an option, but cuttings are preferred to maintain the double-flowered traits.

Pests and Diseases:

Oleanders are generally resistant to most pests and diseases. However, they can occasionally suffer from scale insects, aphids, or spider mites. Treat infestations early with insecticidal soap or neem oil. Ensure proper drainage to avoid root rot, and watch for oleander leaf scorch, a bacterial disease that can be spread by insects.

Toxicity:

Nerium oleander is highly toxic to humans, pets, and livestock if ingested. All parts of the plant, including the sap, are poisonous, so handle it with care, especially when pruning. Use gloves, and ensure that children and pets do not consume any part of the plant.
