Calathea ornata needs high humidity so that it can thrive. So, if you find that the leaves of calathea ornata are curling and the edges may turn brown, it can be a sign that the humidity is too low. So, how to fix this condition?
The Methods to Fix Calathea Ornata Leaves Curling and Brown
According to the House Plant Help site, if it happens because of the lack of humidity around the plant, then you are able to fix the curling leaves by increasing the humidity. It can be done by doing several things below as explained on the HousePlant Help site.
- You have to spray water to the plant regularly. You can fill a spray bottle with lukewarm water and then set it to the ‘mist’ setting. After that, you can spray the air around the leaves of the plant several times in a day.
- You can use a pebble tray. You have to fill a shallow tray with pebbles and then you have to fill about halfway up the pebbles with water. Now, you can put the pot of the plant onto the pebbles and you have to make sure that the bottom of the pot does not touch water. It is called a humidity tray.
- You are able to put your plant near a humidifier. Let’s say that you live in a particularly dry place or the air becomes very dry in the winter. If so, you have to place your calathea plant in the same room as a high-quality houseplant humidifier.
Besides, you have to make sure that you put the plant in a place which is not affected by warm air from wood stoves or heating vents.
The Reasons Why Calathea Ornata Leaves are Curling Up and How to Fix It
The reason why calathea ornata leaves are curling up is not always because of low humidity as explained earlier. It can also happen because of the other reasons as explained below according to the Osera site.
– Calathea Ornata Leaves Curling Up Because of Too Much Sunlight
If your calathea ornata gets too much sunlight, it can make the leaves curl up. It is important for you to know that this plant does not like being under direct sunlight. Let’s say that you live in a country which is often overcast. If so, you can put your plant in the window. However, if you live in a country which often gets sunlight, you have to protect your plant from the strong rays of the sun. Calathea ornata curls their leaves on themselves because it protects itself from the sunlight that it gets too much when it tries to conserve as much water as possible. If the plant is left under sunlight, besides having curling leaves, it will also start to dry out and you will see the edges of the leaves are crisping and turning brown.
– Calathea Ornata Leaves Curling Up Because of Underwatering
If you find that your calathea ornata leaves are curling up, it may be because of underwatering. The plant is trying to conserve water by curling up and you may also see the tips of the leaves are crispy at the same time. If it happens, you are able to check the moisture of the soil often and you have to adjust your watering schedule for warmer weather when your plant tends to dry out more quickly. You can check the moisture by using a moisture stick. When the probes are inserted into the soil, you will get a reading on the moisture levels. By using this tool, you can watch when your plant has to be watered.
Besides the reasons above, on the Bloom Sprouts site, it is also explained that overwatering and over fertilizing can be the cause of leaves curling and browning.
– Calathea Ornata Leaves Curling Up Because of Overwatering
If you over water your calathea ornate, it can waterlog its roots and it can cause root rot. It will lead to dehydration because the roots are damaged and it cannot absorb water or nutrients. Here are some signs of calathea leaves curling because of overwatering according to the Bloom Sprouts.
- The tips of the leaves are brown.
- The soil has a strong, unpleasant smell and usually it is a sign of root rot.
- If your soil is still wet after more than a week or two weeks, it may indicate that it is lacking enough drainage and overwatering.
If the curling leaves happen because of overwatering, you can fix it by making sure that you permit time for the top 2 inches of the soil to dry before you water again. If you find that the soil does not dry up in two weeks, you can repot your plant to a new pot with new soil. You can mix coarse materials such as perlite, shredded bark or even fine gravel into the potting soil to make better aeration and drainage. It is also important for you to make sure your pot has a drainage hole which is designed to drain excess water.
– Calathea Ornata Leaves Curling Up Because of Overfeeding with Fertilizer
You may think that if you feed your calathea ornate more, it can be healthier. Well, this kind of thinking is not true because over-fertilization can cause the soil to be oversaturated with salts around the roots. It can cause water moisture to be drawn out of plants rather than be absorbed. This lack of water will dehydrate the plant and then it will cause it to curl up. If it is left, salt buildup in the soil will cause root burn damage and it will kill your plant. Here are some signs of curled leaves because of over-fertilization according to the Bloom Sprouts.
- There is a crusty build-up on the edges of your pots or on the surface of the soil.
- The lower leaves are yellowing and wilting and the leaf margins and tips are browning.
You are able to fix this condition by removing the plant from the soil and then cutting any rotten roots. After that, you have to fill a new pot with fresh soil and repot the plant. In the future, you have to use the half the dose recommended on fertilizer packaging and make sure that you do not fertilize it more than once per month.
