In the next section, well take a look at some of the most common causes of calla lily browning and how to address them.
Common Causes of Calla Lily Discoloration
Calla lilies are a beautiful and popular flower, but if you notice them turning brown, it can be concerning.
There are several potential causes for this discoloration, including overwatering, too much sun, temperature fluctuations, or even an insect infestation.
In order to understand why your calla lilies may be turning brown, it is important to understand the common causes of this discoloration.
Overwatering is one of the most common causes of calla lily discoloration.
When there is too much water in the soil, the roots can become waterlogged, leading to root rot and discoloration of the leaves and flower.
For this reason, it is important to make sure that you are only watering your calla lilies when the top inch of soil is dry.
Another common cause of discoloration is too much sun exposure.
Calla lilies prefer partial shade, so if they are exposed to too much direct sunlight, the leaves and flowers can turn brown.
To prevent this, make sure to keep your calla lilies in a spot that is partially shaded.
Finally, temperature fluctuations can also cause discoloration of calla lilies.
If the environment is too hot or too cold, the leaves and flowers can turn brown.
For this reason, it is important to keep your calla lilies in an environment that is not too hot or too cold.
If the discoloration persists after taking these steps, it is a good idea to check for any insect infestations and take the necessary steps to address the issue.
Insects such as aphids and mites can cause discoloration of the leaves and flowers.
By taking the time to inspect your calla lilies for signs of insect infestation and treating them accordingly, you can help prevent discoloration and keep your calla lilies looking healthy and vibrant.
Overwatering
Calla lilies need just the right amount of water to keep them happy and healthy.
Too much water can lead to the leaves and petals turning brown, a sign of root rot.
To prevent this, you should only water when the top inch of soil is dry and avoid overwatering.
Make sure to check the soil before each watering and never allow the pot to become waterlogged.
If you notice the leaves and petals turning brown, you can try to save the plant by removing it from the pot and letting the roots dry before re-potting with fresh potting mix and some fertilizer.
It is also important to make sure that your calla lily is not in an area that is too humid or too wet.
If your calla lily is in a spot that is too humid, it can cause the leaves and petals to turn brown as the plant becomes overwhelmed by moisture.
If you keep your lily in a pot, make sure that it has drainage holes in it and if it is in the ground, make sure that it is not in an area that is constantly wet.
Finally, if you are using fertilizer, make sure that it is not too strong or nitrogen-rich.
Too much nitrogen can cause the leaves and petals to turn brown as the plant struggles to process it.
Too Much Sunlight
Calla lilies are a beautiful and popular flower, but if you notice them turning brown, it can be concerning.
One of the potential causes of this discoloration is too much sun exposure.
Too much sunlight can cause the leaves and petals of the calla lily to start to turn brown and wilt.
This can be especially true in the summer months when the sun is at its strongest.
If your calla lilies are exposed to too much direct sunlight, the leaves can become dry and brittle and the petals can start to curl and shrivel.
In extreme cases, the flower might even turn completely brown and die.
To help prevent this, it is important to make sure your calla lilies are not exposed to direct sunlight for more than a few hours a day.
If possible, provide them with some shade in the afternoon and in the evening when the sun is at its strongest.
It is also important to note that too much sun exposure can be exacerbated by other environmental factors.
For example, if your calla lilies are in an area that is hot and dry, they may be more likely to suffer from sun damage.
In this case, it is important to provide them with more shade and regularly mist the leaves with water to keep them hydrated.
By making sure that your calla lilies are not exposed to too much direct sunlight, you can help ensure that they stay healthy and vibrant.
If you notice any discoloration or wilting, it is important to take steps to address the issue quickly in order to keep your calla lilies looking their best.
Temperature Fluctuations
Temperature fluctuations can be a major cause of brown calla lilies.
If temperatures are too hot or too cold, the flowers cells can become damaged and discolored.
In particular, calla lilies are particularly sensitive to cold temperatures, and may begin to brown if exposed to temperatures that dip below 55 degrees Fahrenheit.
In order to prevent your calla lilies from turning brown due to temperature fluctuations, make sure to keep them in a well-ventilated area that is not too hot or too cold.
It is best to avoid exposing your plants to temperatures below 55 degrees Fahrenheit, as well as high temperatures above 85 degrees Fahrenheit.
You should also make sure to keep the air flow in your home consistent, as sudden changes in temperature can cause shock to your plants.
Additionally, keep your calla lilies away from windows and other areas where they may be exposed to direct sunlight.
Insect Infestations
When it comes to insect infestations, one of the most common culprits of browning calla lilies is the aphid.
Aphids are small sap-sucking insects that can cause a variety of problems for your calla lily plants.
They feed on the sap from the stems and leaves, which can cause the plant to become discolored and wilted.
Additionally, they can also attract other insects, such as ants, which can further damage your plants.
To check for aphids, look closely at the stems and leaves of your calla lilies and look for small, greenish-yellow insects.
If you find them, it is important to take the necessary steps to address the issue as soon as possible.
Another insect that can cause browning of calla lilies is the thrips.
Thrips are small, slender insects that feed on the pollen and nectar of flowers, causing them to become discolored and misshapen.
They can also spread viruses and diseases to your plants, so it is important to take steps to prevent and control them.
To check for thrips, look closely at the flowers and leaves of your calla lilies and look for small, dark-colored insects.
If you find them, take the necessary steps to address the issue as soon as possible.
Finally, another potential culprit of browning calla lilies is the spider mite.
Spider mites are small, eight-legged insects that feed on the leaves of plants, causing them to become discolored and wilted.
They can also spread viruses and diseases to your plants, so it is important to take steps to prevent and control them.
To check for spider mites, look closely at the underside of the leaves of your calla lilies and look for small, red or white insects.
If you find them, it is important to take the necessary steps to address the issue as soon as possible.
In conclusion, if you notice your calla lilies turning brown, there may be several potential causes, including overwatering, too much sun, temperature fluctuations, or an insect infestation.
