From finding the perfect spot for it to thrive to keeping it happy and healthy all year round, we’ve got you covered. Whether you’re a seasoned green thumb or just dipping your toes into gardening, this guide is your go-to for everything you need to know about growing mandevilla.

Choosing the Right Location

The first step in successfully growing mandevilla is selecting the right location. Mandevilla thrives in full sun to partial shade, so choose a spot that receives at least 6 hours of sunlight per day. Additionally, ensure the location has well-draining soil to prevent waterlogging, as mandevilla doesn’t tolerate standing water.

Selecting the Right Variety

Before planting mandevilla, it’s essential to choose the right variety for your specific climate and space. There are several types of mandevilla available, including:

Mandevilla sanderi:

Known for its vibrant pink, red, or white flowers, this variety is perfect for adding a pop of color to your garden.

Mandevilla boliviensis:

Featuring trumpet-shaped flowers in shades of yellow or pink, this variety is ideal for cascading over fences or trellises.

Mandevilla splendens:

With its large, showy flowers and glossy green leaves, this variety is a favorite among gardeners for its beauty and versatility.

Planting Mandevilla

Once you’ve chosen the right location and variety, it’s time to plant your mandevilla. Follow these steps for successful planting:

Prepare the Soil:

Dig a hole twice as wide and deep as the mandevilla’s root ball. Amend the soil with compost or organic matter to improve drainage and fertility.

Planting:

Gently remove the mandevilla from its container and loosen the roots. Place the plant in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill the hole and water thoroughly to settle the soil.

Support:

If you’re growing a climbing variety of mandevilla, provide support such as a trellis or stake to encourage upward growth.

Watering and Care

Proper watering is essential for the health and vitality of mandevilla. Here are some tips for watering and care:

Watering: Water mandevilla regularly, keeping the soil consistently moist but not waterlogged. Allow the soil to dry slightly between waterings, especially during the winter months when growth slows down.

Fertilizing: Feed mandevilla with a balanced fertilizer every two weeks during the growing season to promote healthy growth and abundant flowering.

Pruning: Prune mandevilla as needed to maintain its shape and encourage bushier growth. Remove any dead or damaged branches, as well as spent flowers, to promote continuous blooming.

Overwintering: In colder climates, mandevilla can be overwintered indoors to protect it from frost. Place the plant in a sunny location and reduce watering during the dormant season.

Dealing with Pests and Diseases

While mandevilla is relatively resistant to pests and diseases, it’s essential to keep an eye out for common issues such as aphids, mealybugs, and powdery mildew. Here are some tips for dealing with pests and diseases:

Natural Remedies:

Use insecticidal soap or neem oil to control aphids and mealybugs. Additionally, prune affected plant parts and dispose of them properly to prevent the spread of disease.

Preventative Measures:

Ensure proper air circulation around mandevilla plants to reduce the risk of powdery mildew. Avoid overhead watering, as wet foliage can contribute to fungal infections.

Seasonal Care Guide

Mandevilla requires different care routines depending on the season. Here’s a seasonal care guide to help you keep your mandevilla healthy year-round:

Spring: In spring, as temperatures start to rise, increase watering frequency to support new growth. Fertilize mandevilla with a balanced fertilizer to provide nutrients for vigorous blooming throughout the season. Prune any dead or leggy growth to encourage bushier growth.

Summer: Summer is the peak growing season for mandevilla, so continue to water regularly and fertilize every two weeks to support abundant flowering. Keep an eye out for pests such as aphids and mealybugs, and treat promptly if necessary. Provide support for climbing varieties to ensure they grow upward and outward.

Fall: As temperatures start to cool in fall, gradually reduce watering and stop fertilizing to allow mandevilla to enter dormancy naturally. Prune back any overgrown or leggy growth to maintain a compact shape. Bring potted mandevilla indoors before the first frost if you live in a colder climate.

Winter: In winter, mandevilla enters a period of dormancy, so reduce watering and allow the soil to dry out slightly between waterings. Keep mandevilla in a cool, bright location indoors, away from drafts and direct heat sources. Prune lightly as needed to remove any dead or damaged growth.

Mandevilla Companion Plants

Pairing mandevilla with the right companion plants can enhance its beauty and create a stunning display in your garden. Here are some companion plants that pair well with mandevilla:

Bougainvillea: With its vibrant colors and climbing habit, bougainvillea makes an excellent companion for mandevilla, creating a striking contrast of textures and colors.

Verbena: Verbena’s delicate flowers and trailing growth habit complement mandevilla’s upright growth, creating a beautiful cascading effect in hanging baskets or containers.

Mandevilla in Indoor Spaces

While mandevilla is typically grown outdoors, it can also thrive as a houseplant with the right care. Here are some tips for growing mandevilla indoors:

Light: Place mandevilla in a bright, sunny window where it can receive at least 6 hours of sunlight per day. Rotate the plant periodically to ensure even growth.

Temperature: Mandevilla prefers warm temperatures between 60-80°F (15-27°C) during the day and slightly cooler temperatures at night. Avoid placing mandevilla near drafty windows or heat vents, as temperature fluctuations can stress the plant.

Watering: Water mandevilla thoroughly when the top inch of soil feels dry to the touch, allowing excess water to drain away. Avoid overwatering, as soggy soil can lead to root rot.

Humidity: Mandevilla prefers high humidity, so mist the foliage regularly or place a humidifier nearby to increase moisture levels.

Support: Provide support such as a trellis or stake to support climbing varieties of mandevilla and encourage upward growth.
