Reasons & Solutions to Fix Bird of Paradise Plant Leaves Curling
If your home is sweltering or your plants are near heat sources, the bird of paradise plant leaves may start curling upwards or inward. Why? Too much heat will mean faster water loss, and plants will respond by curling leaves to reduce the loss. If the temperature is too high, your plant’s normal physiological function will cease to work usually. This means nutrients and water won’t reach the leaves, and they will also curl. Learn the temperature requirements of Bird of Paradise Plant to take of your plant better.
Signs of Too Much Heat
Signs of too much heat will resemble those of low humidity or a thirsty plant. Besides leaf cupping and rolling, you will see brown tips and margin edges, leaf or flower drop, and wilting. If ignored, your bird of paradise plant may die.
Maintain moderate to warm temperatures year round. In addition, do not plant the bird of paradise in a location that is too close to a heat source or an air conditioning vent. To help the plant survive temperature changes, move it to a warmer location and shade it from the scorching afternoon sun. Watering can also be increased slightly. Read More:
Underwatering is the most common reason for the bird of paradise plant leaves curling inward or upward. When thirsty, the plant will curl leaves. This is to reduce their surface area to minimize water loss by transpiration. Learn the water requirements of Bird of Paradise Plant to take of your plant better.
Signs of Inadequate Watering
Besides birds of paradise curled leaves, the soil will be dry, and the leaves will have crispy, brown tips and edges or margins. Also, the plant may wither or wilt – the leaves will droop. Other signs are leaf yellow and stunted growth. If you don’t rectify the issue, leaves may drop, and your plant will eventually die.
Maintain a regular watering schedule for your bird of paradise. Water thoroughly when the top couple inches of soil are dry. Check the plant frequently until you have determined the appropriate watering schedule for your plant and environment. Maintain high humidity by running a humidifier, misting the leaves two times per week, or setting up a pebble tray under the plant.
The second most likely reason for the bird of paradise leaves curling is low humidity. These subtropical plants thrive in warm places with high humidity. When humidity drops too much, the potting mix and leaves will quickly lose water and start curling. They are doing so to reduce further loss. Learn the humidity requirements of Bird of Paradise Plant to take of your plant better.
Signs of Low humidity
Signs are similar to those of an underwatered bird of paradise. They include yellow leaves, browning of edges and tips, stunted growth, and dry and crispy feeling leaves. Also, expect the curling upward, and the leaves may droop or curl downward. If you don’t correct the problem, it will wilt and eventually die.
To prevent further curl, raise the humidity around your Bird of Paradise. Here are some ways to raise humidity:
Buy a humidifier. A humidifier is the best way to control humidity.
Make a pebble tray
Mist your plant once or twice a week. Be careful not to leave its leaves dripping wet, as this can cause fungal infections.
Group plants together – it will help create a microclimate with high humidity
Move your Strelitzia to rooms with higher humidity, like your bathroom or kitchen.
Adjust the watering to cater for the much loss by transpiration and evaporation from the potting mix.
As large plants, especially the white bird of paradise, we don’t think a greenhouse cabinet or terrarium will be a brilliant idea.
Too Much Light
Birds of paradise plant can withstand full sun, bright, indirect light, or even medium light. However, too much direct sunlight is a possible sign of leaves curling inward. The hot sun will cause a lot of water evaporation, and the leaves will curl to reduce the loss. Also, it may be a means to reduce the area exposed to light and consequently heat. When plants absorb light, they convert excess to heat. Learn the light requirements of bird of paradise plant to take care of your plant better.
Signs of Too Much Light
Leaves will look pale, washed out, or yellowish except on the prominent veins. Also, the leaf margin and tips will become crispy, brittle, and turn brown. Other signs are leaves dropping.
To eliminate this problem, you have to find the right place for your plant. The best is to place it against an east or west window and gradually increase the amount of sun it receives. This way you will know exactly how much sunlight your Bird of Paradise can handle. Also, a slight increase in the amount of water during watering can make it easier for the plant to recover.
Overwatering & Root Rot
Overwatering will not cause a direct cause for the bird of paradise leaves curling. But a constantly soggy or wet soil will increase the chance of root rot. Your plant won’t absorb oxygen, and the roots will be weaker. Also, these conditions favor some fungi or bacteria, which will multiply and attack the roots. When root rot sets in, your plant won’t be able to absorb water and other nutrients. So, it will end up with curled leaves because it doesn’t get enough moisture.
Signs of Overwatering or Root Rot
The first sign is the yellowing of leaves and a wet or molded potting mix. Also, bird of paradise plant leaves may curl, have brownish splotches, and your plant will look limp. As it gets serious, expect signs like an excessive leaf dropping, a mushy stem base, stunted growth, wilting, and death.
You can save an over-watered plant by allowing it to completely dry out before watering again if the roots are not showing signs of decay.
If any parts of the plant are salvageable after root rot is discovered, they can be disinfected with diluted hydrogen peroxide and replanted into new soil and a new pot.
If you don’t often repot your plant, they get pot or rootbound characterized by tangled, curled, and dense root mass with growth room. This will choke the plant, meaning it will not get enough nutrients or water, and the leaves will start curling.
Signs of RootBound
Apart from the bird of paradise curled leaves, expect to see some roots growing from the drainage holes. Other signs are yellowing and dropping leaves, especially those closer to the bottom, and stunted growth. Also, if blooming time, it may not flower, and leaves will be smaller.
Repot your bird of paradise if there are any signs of the plant being rootbound – roots coming out of the drainage holes or growing out of the top of the soil.
For transfer shock, try to disturb the plant as little as possible. Put it in the same location while maintaining the same watering and fertilizing schedules. Even if the leaves curl after repotting, the plant should rebound within a couple of weeks.
A heavy infestation of the sap-sucking pests like scale, mites, and trips like Chaetanaphothrips signipennis is a cause for Crane flower, or white bird of paradise leaves curling. This happens because they will suck the juices depriving the leaves of moisture. Some have toxins that deform and make leaves curl.
Signs of Pests
The sign will depend on the exact bug your Strelitzia plant has. These telltale signs include holes, spots (brown, yellowish, or black), webbing, honeydew, and sooty mold. More signs are distorted and curly leaves.
Check your plant regularly for any sign of pests. Treat the plant with an insecticidal soap or neem oil at the first sign of any pests. You can also treat the plant once every or every other month as a preventative.
Too Many Fertilizers
Fertilizers will promote health and lush leaves. However, too much, especially those rich in nitrogen, may make your bird of paradise leaves curl downwards. The leaves will also be too dark and dull. Also, many plant food will encourage quick root growth, making your plant pot bound or affecting the usual microorganism balance (may alter normal absorption).
Signs include crusts of fertilizer appearing on the soil, yellow leaves, stunted growth, and leaves dropping. If you apply too much fertilizer, expect some wilting, very dark leaves. Also, the leaf tips and edges may turn brown.
First, remove any visible fertilizer and flush your pot the same way as to treat hard water damage, mentioned above. This will remove the excess fertilizer. Only fertilize your Bird of Paradise during the warm months of the year. It does not grow at all during winter, and any fertilizer in the soil will simply stay there until it starts doing damage.
Usual Reasons for Bird of Paradise Curling Leaves
Not all cases for the bird of paradise curling leaves should worry you. Here are some usual issues:
New Unfurling Leaves
When they emerge, new Strelitzia leaves will remain curled as they grow longer. Afterward, they will start unfurling. This process can take some time. It is normal. Just ensure it happens to the new, light-green leaves only.
Older aging leaves may be yellowish then brownish. Also, some parts may curl. If the upper leaves are healthy, prune the yellow and dying leaves. These leaves depend on the plant, yet they no longer contribute. At this time, it’s time to propagate a new plant or buy one. Read more for how to propagate Bird of Paradise.
Repotting, Transplant or Moving Shock
If you recently repotted, transplanted, or moved your plant, it may suffer from a bit of shock. This will cause the leaves to curl. If that is why leaves on your bird of paradise curling, give it a little time. It will adjust and start growing as usual. But ensure you maintain the right conditions.
Re-potting shock is temporary. It should bounce back in a few days and uncurl its leaves.
Because they grow so tightly in the wild, your Bird prefers to be slightly root-bound. Once every two years is about right.
Re-pot in the early spring. Partially dormant plants suffer less shock.
How to Prevent Bird of Paradise Leaves Curling
Your Bird of Paradise plant will be simple to care for once you understand the basics. Those curling leaves are simply a cry for assistance in the only language your plant understands. The sooner you notice it, the easier it is to fix. Keep your Bird of Paradise hydrated, fed, and in a bright, warm location. Keep an eye out for pests and don’t overwater.
