Mandevilla plants are beautiful, flowering vines that can add a pop of color to any garden or home. However, like all plants, they require proper care and attention in order to thrive. One of the most challenging aspects of caring for Mandevilla plants is dealing with dormancy. If you’ve noticed that your Mandevilla vine looks lifeless and isn’t producing any new growth, it’s likely that it has entered a dormant state. But don’t worry – with a bit of knowledge and effort, you can revive your dormant Mandevilla and enjoy its beautiful blooms once again.
Understanding the Basics of Mandevilla Plants
Before we dive too deep into dormancy, it’s helpful to have a basic understanding of Mandevilla plants. These vines are native to Central and South America and are prized for their large, trumpet-shaped flowers that come in shades of pink, red, white, and yellow. Mandevilla plants require plenty of sunlight and warm temperatures in order to thrive. They also need well-draining soil and regular watering and feeding.
In addition to their beautiful flowers, Mandevilla plants are also known for their ability to attract hummingbirds and butterflies to your garden. These pollinators are drawn to the nectar-rich flowers and can help to increase the overall health and biodiversity of your outdoor space. However, it’s important to note that Mandevilla plants are toxic to pets and humans if ingested, so be sure to keep them out of reach of curious animals and children.
What Does it Mean When Your Mandevilla Goes Dormant?
If your Mandevilla vine suddenly stops growing and its leaves turn yellow and fall off, it’s likely that it has entered a dormant state. This means that the plant has essentially gone into hibernation mode in response to environmental factors like changes in temperature and light. While dormancy is a natural process for plants like Mandevilla, it can be frustrating for gardeners who want their plants to be constantly in bloom.
During dormancy, it’s important to reduce watering and fertilization to avoid overstimulating the plant. It’s also a good idea to move the plant to a cooler, darker location to mimic its natural environment during the dormant period. Once the plant begins to show signs of new growth, gradually increase watering and fertilization to encourage healthy growth. Remember, dormancy is a necessary part of the plant’s life cycle and is nothing to be alarmed about.
Causes of Dormancy in Mandevilla Plants
There are many factors that can trigger dormancy in Mandevilla plants, including:
- Temperature changes: Mandevilla plants prefer warm temperatures and will go dormant if they are exposed to temperatures below 50 degrees Fahrenheit for an extended period of time.
- Light changes: Mandevilla plants require plenty of sunlight in order to bloom. If they are suddenly exposed to significantly less light due to seasonal changes or a change in their environment, they may enter dormancy.
- Watering and feeding: Mandevilla plants need regular watering and feeding in order to thrive. If they are not receiving enough water or nutrients, they may go dormant.
- Pests and diseases: If your Mandevilla plant is suffering from a pest infestation or disease, it may go dormant as a way to conserve energy and protect itself.
In addition to the above factors, Mandevilla plants may also go dormant during the winter months. This is a natural response to the shorter days and cooler temperatures of the season. During this time, it is important to reduce watering and fertilization to allow the plant to rest. Once spring arrives and temperatures begin to warm up, the plant will come out of dormancy and start to grow again.
How to Identify Dormant Mandevilla
Identifying a dormant Mandevilla plant is fairly straightforward. Look for the following signs:
- Yellowing leaves that eventually fall off
- A lack of new growth or blooms
- A woody, brown stem
- The plant appears dry and lifeless
It is important to note that Mandevilla plants naturally go dormant during the winter months, so if you notice these signs during that time, it may not necessarily mean the plant is unhealthy. However, if you notice these signs during the growing season, it could be a sign of a problem.
To help prevent dormancy during the growing season, make sure your Mandevilla plant is getting enough sunlight and water. Additionally, fertilizing the plant regularly can help promote healthy growth and prevent dormancy.
Steps to Revive a Dormant Mandevilla Plant
If you’ve determined that your Mandevilla plant is dormant, don’t worry – there are several steps you can take to revive it:
- Move the plant to a warmer location: Mandevilla plants need warmth and sunlight in order to thrive. If you’ve noticed that your plant is dormant, move it to a warmer location where it can receive plenty of sunlight.
- Prune the plant: Pruning a dormant Mandevilla can encourage new growth. Remove any dead or damaged branches and cut back the remaining branches to promote new growth.
- Water and feed the plant: Mandevilla plants need regular watering and feeding in order to thrive. Give your plant plenty of water and fertilizer to encourage new growth.
- Provide support: If your Mandevilla plant is a vine, provide it with support so that it can start climbing and growing again.
It’s important to note that while Mandevilla plants can go dormant during the winter months, they can also become dormant if they are not receiving enough water or nutrients. Make sure to check the soil regularly and water the plant when the top inch of soil feels dry. Additionally, consider adding a slow-release fertilizer to the soil to provide the plant with the necessary nutrients to thrive.
Tips for Overwintering Mandevilla Plants
If you live in an area with cold winters, it’s important to take steps to protect your Mandevilla plants from the cold. Here are a few tips:
- Move your plants indoors: If possible, move your Mandevilla plant indoors during the winter months. Keep it in a warm, sunny location and continue to water and care for it as normal.
- Cut the plant back: If you can’t move your Mandevilla plant indoors, consider cutting it back to a smaller size so that it requires less energy to survive the winter.
- Cover the plant: If your Mandevilla is planted in the ground, cover it with a layer of mulch or a frost cloth to protect it from the cold.
Another tip for overwintering Mandevilla plants is to reduce watering during the winter months. Since the plant is not actively growing, it does not require as much water as it would during the warmer months. Overwatering can lead to root rot and other issues, so it’s important to monitor the soil moisture levels and only water when necessary.
Additionally, you can provide extra insulation for your Mandevilla plant by placing a layer of straw or hay around the base of the plant. This will help to keep the roots warm and protected from the cold. Just be sure to remove the insulation in the spring when the weather warms up to prevent any mold or mildew from forming.
Best Practices for Caring for Dormant Mandevilla
Once you’ve revived your dormant Mandevilla plant, it’s important to care for it properly in order to prevent dormancy from occurring again. Here are a few best practices to keep in mind:
- Water and feed your plant regularly: Mandevilla plants need regular watering and feeding in order to stay healthy and prevent dormancy. Make sure your plant is getting enough water and nutrients, especially during the growing season.
- Provide support: If your Mandevilla is a vine, provide it with support so that it can climb and grow properly.
- Prune your plant regularly: Pruning your Mandevilla plant regularly can help prevent it from becoming too leggy and encourage healthy growth and blooms.
- Protect your plant from pests and diseases: Keep an eye out for pests and diseases that can damage your Mandevilla plant. Take steps to prevent and treat these issues as soon as possible.
Common Mistakes to Avoid When Dealing with a Dormant Mandevilla

- Don’t move your plant too often: Moving your Mandevilla plant around too often can disrupt its growing cycle and cause it to go dormant.
- Don’t prune your plant too aggressively: While pruning can encourage new growth, pruning your Mandevilla plant too aggressively can damage it and make it more susceptible to pests and diseases.
