The oleander bush is a member of the Dogbane family that is also called by its botanical name of Nerium oleander. As a traveler from Asian-influenced Middle Eastern and European culture, the oleander bush's exotic, fragrant blooms have made it a welcome guest in stateside gardens as well. Oleander bushes are summer and fall bloomers who enjoy warm weather and outdoor growing conditions, although they can also be grown indoors under the right conditions. Oleander blossom colors can range from pink to white to yellow to orange to red and beyond. The oleander plant is considered to be toxic and poisonous, which can be a consideration when installing these plants in homes with small children or pets. Learn from experts about how to care for and water your oleander plant.
The oleander bush is considered drought resistant and can fare well at maturity with just minimal watering. However, as new oleander bushes are becoming established, it can be helpful to keep soil moist so the young plant can get the best start. Additionally, oleander bushes cultivated indoors will need more and more frequent watering than their outdoor cousins will.
For outdoor oleander bushes, water as needed and only if natural rainfall provides less than one inch of water per week. Using a drip or irrigation hose can provide slow, steady moisture to the oleander bush root system. For indoor growing oleander bushes, in the spring, summer and fall seasons, ensure the plant receives the equivalent of approximately one inch of water per week. This amount can be halved during the winter dormant season. For indoor pot growing oleanders it can be a good practice to place a water tray filled with moss or pebbles beneath the pot so the plant can simply absorb water as needed.
