With our expert tips and guidelines, you’ll be able to create a thriving mandevilla indoor garden that will brighten up any space in your home.
1. Choosing the Right Location for Your Indoor Mandevilla Plants
Determining the Ideal Lighting Conditions
One of the most crucial factors for the successful growth of mandevilla plants indoors is providing them with adequate lighting conditions. As tropical plants, mandevillas thrive in bright, indirect sunlight. Place your mandevilla plants near a south-facing window where they can receive at least 4 to 6 hours of sunlight every day.
If you don’t have access to a suitable window or if the natural light in your home is limited, you can supplement it with artificial grow lights. LED grow lights are ideal for indoor mandevilla care as they emit the right spectrum of light needed for plant growth. Position the lights 6 to 12 inches above the plants and keep them on for 12 to 14 hours a day.
Considering the Optimal Temperature and Humidity Levels
Mandevilla plants prefer warm temperatures and thrive in a range of 60 to 80°F (15 to 27°C). Avoid exposing them to temperatures below 50°F (10°C) as this can cause damage to the plant. It’s essential to maintain a consistent temperature as extreme fluctuations can stress the plant and affect its growth.
In terms of humidity, mandevillas are accustomed to higher humidity levels. You can increase humidity around the plants by using a humidifier or placing a tray filled with water and pebbles near the plants. Regular misting of the leaves can also help emulate a tropical environment.
2. Watering and Fertilizing Mandevilla Plants Indoors
Establishing a Proper Watering Routine
Proper watering is crucial for the health and vigor of your indoor mandevilla plants. Water the plants when the top inch of the soil feels dry to the touch. Use tepid water to prevent shocking the roots. Avoid overwatering as it can lead to root rot and other fungal diseases.
During the growing season, which typically spans spring and summer, water the plants more frequently. Reduce watering during the dormant period in fall and winter. Be mindful not to let the plants sit in standing water, as it can also promote root rot.
Nourishing the Plants with Fertilizer
Mandevilla plants benefit from regular feeding to support their growth and blooming. Use a balanced water-soluble fertilizer with an NPK ratio of 20-20-20 or a fertilizer specifically formulated for flowering plants. Follow the manufacturer’s instructions for dosage and frequency.
During the active growing season, fertilize your mandevilla plants every two weeks. Reduce fertilization to once a month during the dormant period. Always water the plants before applying fertilizer to avoid any potential root burn.
3. Pruning, Repotting, and Propagating Mandevilla Plants Indoors
Pruning to Promote Bushier Growth and Blooming
Regular pruning is essential for shaping and maintaining the desired size of your indoor mandevilla plants. Prune the plants in early spring before new growth emerges. Use sharp and clean pruning shears to prevent the spread of diseases.
Start by removing any dead or damaged branches and then proceed to thin out crowded areas. Pinching back the growing tips encourages bushier growth. You can also remove faded flowers to encourage continuous blooming.
Repotting to Provide Adequate Space and Nutrients
As mandevilla plants grow, they will eventually outgrow their containers and require repotting. Repot your mandevilla plants every 1 to 2 years or whenever you notice the roots becoming overcrowded. Choose a pot that is 2 inches larger in diameter than the current one and ensure it has drainage holes.
Use a well-draining potting mix composed of equal parts peat moss, perlite, and compost. Gently remove the plant from its current container, untangle any tangled roots, and place it in the new pot. Fill the remaining space with the potting mix and water thoroughly.
Propagating Mandevilla Plants Through Stem Cuttings
If you’d like to expand your mandevilla collection or share the joy of growing mandevillas with friends and family, you can propagate them through stem cuttings. The best time to take cuttings is in late spring or early summer when the plants display active growth.
Select a healthy and mature stem from the parent plant and make a clean cut just below a node. Remove the lower leaves, leaving only a few at the tip. Dip the cut end in rooting hormone powder and plant it in a small pot filled with a well-draining rooting mix. Keep the soil consistently moist and place the cutting in a warm and bright location, but away from direct sunlight. Within a few weeks, roots should develop, indicating successful propagation.
