Alice du Pont mandevilla vines are known for their beautiful pink or red flowers that add a tropical flair to gardens. However, these vining plants can sometimes start to droop, lean, or fall over – which can be worrying for gardeners. There are a few key reasons why your Alice du Pont mandevilla vine may be falling over and tips on how to restore it to an upright, vigorous growth habit.
Reasons for Falling Over
Improper Support
As a vining plant, mandevilla relies on some type of support structure to climb upwards. Without a trellis fence arbor, or other support, the vine can start to droop down under its own weight. Providing a sturdy support structure and gently tying and training new growth to climb upwards can prevent leaning and falling over.
Overwatering
Too much moisture around the roots can lead to root rot, which damages and weakens the root system. This prevents the vine from taking up adequate water and nutrients, resulting in the stems and leaves wilting and falling over. Allow the soil to dry out slightly between waterings.
Underwatering
On the flip side, inadequate watering leads to drought stress causing the vine to wilt and collapse. Stick your finger into the soil to check moisture levels and water thoroughly when the top few inches become dry.
Excessive Pruning
While regular pruning of mandevilla is needed, cutting back too much at once can shock the plant. This can stunt growth and weaken stems, leading to drooping. Prune lightly, removing no more than 30% of growth at one time.
Insufficient Sunlight
Mandevillas need at least 6 hours of direct sunlight daily to thrive. Too much shade will cause leggy, weak growth that cannot support itself upright. Move to a sunnier location or prune back encroaching trees/shrubs.
High Winds
Strong winds can batter and blow mandevilla vines around, causing them to fall over if they are not sturdily supported. Install windbreaks or move container grown vines to more protected areas.
Pests or Diseases
Issues like stem-damaging borers, root-attacking fungi, or foliage-feeding insects can impair health. Inspect regularly and take action if pests or disease are found. Removing affected parts, quarantining, and using organic treatments can help.
Cold Weather
Chilly temperatures below 50°F can damage mandevillas. If exposed to frost or freezing weather, the vine may rapidly wilt and collapse. Protect from cold spells or move indoors until temperatures warm up again.
How to Fix a Falling Mandevilla Vine
If your Alice du Pont mandevilla is falling over, drooping, or sprawling instead of climbing upward, there are a few tactics you can try to rehabilitate it:
-
Add Support– Install trellises, cages, poles, wires, or other structures near the base of the plant to provide support. Gently tie new growth to the supports to train upwards.
-
Check Soil Moisture– Feel the soil to ensure it is not too wet or too dry. Adjust your watering practices accordingly.
-
Move to Better Light– Place the plant where it will receive at least 6 hours of direct sun daily.
-
Prune Selectively– Trim back overgrown, crossing, or damaged stems by no more than 30% to encourage upright growth.
-
Treat Pests/Diseases– Apply organic pesticides or fungicides if insects or disease are present. Remove badly affected parts.
-
Protect from Cold– Cover or bring indoors if temperatures drop below 50°F. Provide warmth until the weather warms again.
-
Avoid Overcrowding– Give the vine ample space and increase air circulation to prevent fungal issues.
-
Use Fertilizer– Apply a balanced fertilizer every 2-3 weeks in the growing season to nourish and strengthen growth.
-
Check Roots– If wilting persists, check for root rot. Prune affected roots and repot in fresh soil if necessary.
-
Stake Stems– Insert stakes around the base and gently tie overly long stems to keep them upright.
Long Term Care
To prevent recurrent falling over, focus on providing proper care for your Alice du Pont mandevilla vine:
-
Water thoroughly when the top few inches of soil become dry. Avoid oversaturation.
-
situate in an area receiving at least 6 hours of direct sunlight daily.
-
Prune lightly and selectively during the growing season to remove dead or damaged stems and shape growth.
-
Apply a balanced fertilizer every 2-3 weeks to encourage vigorous growth.
-
Check for pest and disease problems early and take prompt action to resolve them.
-
Install sturdy trellises, arbors, fences or other structures to provide vertical support.
-
Protect from strong winds, staking and tying growth if needed.
-
Move container grown vines to sheltered areas over winter. Cover or bring indoors when frost is expected.
By addressing the underlying causes of falling mandevilla vines and providing attentive care, you can get your Alice du Pont back to growing happily upright. Consistent maintenance and preventative steps will help avoid leaning, drooping and sprawling in the long run. Soon you will have a thriving, climbing mandevilla vine covered in beautiful blooms to enjoy all season long.

FAQ
What does an overwatered mandevilla look like?
Why is my mandevilla drooping?
What causes mandevilla buds to fall off?
Can you overwater Mandevillas?
Why do Mandevilla leaves drop?
If the temperature is too high or too low, it can also cause leaf drop, so make sure your Mandevilla is in an area with a consistent temperature. Wind can damage the plant and cause leaves to drop, so make sure it’s in a sheltered area or provide support if it’s a climbing vine. Pests and diseases can also cause Mandevilla leaves to drop.
How to prevent premature leaf drop in Mandevilla plants?
To prevent premature leaf dropping in Mandevilla plants, it is important to provide them with optimal growing conditions. Here are some tips: Adequate sunlight: Mandevillas thrive in full sunlight. Ensure they receive at least 6-8 hours of direct sunlight each day to promote healthy foliage and minimize leaf drop.
Is it normal for Mandevilla plants to lose leaves?
Yes, it is normal for Mandevilla plants to experience leaf loss during certain seasons. Mandevillas are tropical and subtropical plants that are sensitive to changes in environmental conditions. In many cases, Mandevilla plants go through a natural process of shedding older leaves to make room for new growth.
Why does my Mandevilla plant turn yellow?
Avoid leaving the potting sitting in a tray of water as this can cause the roots to rot and the plant can die. When the roots are affected by fungal rot, won’t be able to absorb water or nutrients as easily, so the plant cannot grow properly. This, in turn, causes the leaves of the mandevilla plant to turn yellow and the plant can die.
