What is Oleander?

The Oleander shrub is a flower belonging to the genus Nerium. It is native to the Mediterranean region and is also commonly found in parts of Asia.

Oleander is known for its attractive, showy flowers, which can be found in various colors, including white, pink, red, and yellow.

Mature Height

Oleander can grow as a large flowering shrub or a small tree. On average, it reaches a mature height of about 6 to 12 feet (1.8 to 3.7 meters) tall.

However, it can grow even taller in optimal conditions, sometimes up to 20 feet tall. The plant’s height depends on climate, good or poor soil, and heavy pruning practices.

Growth Rate

How fast do oleanders grow? Oleander is known for its relatively fast growth rate. Under favorable conditions, it can grow at about 2 to 3 feet (0.6 to 0.9 meters) per year.

Its rapid growth makes it ideal for quickly creating privacy screens and hedges or filling landscape spaces.

Ornamental Features

Oleander is valued for its ornamental value, making it a popular choice in gardens and landscapes.

How To Make Oleanders Grow Faster?

care of oleander

Caring for oleanders is quite demanding, which requires frequent watering, compost and mulch applying, as well as both light and extensive pruning.

Also, you’d better keep an eye on pests and diseases.

Water Regularly During Hot Days

Do oleanders need a lot of water? Oleanders thrive in well-draining soil. However, they do require frequent watering during the hot summer months.

Ensure that the soil around these beautiful plants remains consistently moist, but avoid waterlogging or standing water, as it is an easy recipe for root rot.

Deep watering is essential, as it encourages the roots to grow deeper into the well-draining soil, making this popular house plant more drought-resistant.

However, there is one thing you should remember. Despite the ability to endure drought, oleanders may experience stress and reduced healthy growth during prolonged dry spells.

Use a soaker hose or drip irrigation system to deliver water directly to the root zone, reducing water waste and minimizing foliage wetting, which can cause fungal diseases.

Apply Compost Each Spring

Compost is a valuable source of organic matter and nutrients for your oleanders.

In early spring, before new growth begins, apply a 1 to 2-inch layer of compost (or balanced fertilizer for oleanders) around the base of this poisonous plant, extending out to the drip line.

Compost improves soil structure, enhances water retention, and promotes beneficial microbial activity, supporting the overall health and growth of these beautiful plants.

Add Mulch

Mulching is beneficial for maintaining well-drained soil moisture and temperature and suppressing weeds around the oleanders.

Apply a 2 to 3-inch layer of organic mulch, such as shredded leaves, wood chips, or pine straw, around the base of the plants.

Keep the mulch away from direct contact with the stems to prevent potential rot and allow air circulation.

Prune Lightly After The Main Bloom Period

Conduct light pruning after the main blooming period, typically in late summer or early fall to remove spent single flowers and any dead or diseased wood.

Use clean and sharp pruning shears to cut the stem tips precisely, avoiding tearing or damaging the branches.

Light pruning encourages the development of new flowering shoots and stimulates the entire plant to produce more blooms.

Conduct Extensive Pruning (In Spring)

The primary goal of extensive pruning is to remove any dead, diseased, or damaged branches.

These branches not only detract from the appearance of this popular house plant but can also hinder its healthy growth.

Extensive oleander pruning is simpler than Mexican bird of paradise pruning, which involves selectively removing any weak or overcrowded branches, allowing more light and air to penetrate the interior of this poisonous plant.

Perform this task on your oleanders during late winter or early spring, just before the start of the growing season.

This timing enables these beautiful plants to recover and put their energy into healthy growth during the active growing months.

  • When making cuts, use the three-cut method for larger branches. This involves making an initial cut on the underside of the branch to prevent bark tearing, followed by a second cut from the top, a few inches out from the first cut.
  • The final cut is made just outside the branch collar, the swollen area where the branch connects to the main stem.
  • Make clean cuts just above the flower buds or lateral shoots for smaller branches to encourage new growth in the desired direction.

Stay Alert Of Possible Pest And Disease Problems

Despite being highly toxic to most animals, the leaves of oleander shrubs serve as a delectable feast for the oleander caterpillar and other pests like aphids, whiteflies, spider mites, or mealybugs.

Look out for symptoms of common oleander diseases, such as leaf spots, powdery mildew, or oleander leaf node.

Early detection of pests and diseases allows for prompt intervention, such as using insecticidal soaps for pests or applying fungicides for fungal diseases.

Proper cultural practices, such as avoiding overhead frequent watering and maintaining good plant hygiene, can help prevent pest and disease issues.
