Have you ever been stumped as to why your Swiss cheese plant is turning brown? Don’t worry, you’re not alone. This is a relatively common issue for homeowners and plant-lovers alike, and luckily, there are a number of potential solutions to this problem. Before you reach for the pruners or a spray bottle of Roundup, it is important to identify what might be causing your Swiss cheese plant to turn brown, as treatment and prevention will look different depending on the cause.
If your Swiss cheese plant is turning brown, the three most common culprits are either too much water, too little water, or a fungal infection.
Too Much Water
Swiss cheese plants are native to the tropics, so they naturally prefer slight moist soil rather than dry. However, if the soil is too wet or the humidity levels are too high, the plant’s cells may rupture and the leaves will turn brown and mushy. To prevent this issue from happening, be sure not to overwater your Swiss cheese plant, as too much water can cause root rot.
Too Little Water
Similar to the issue of having too much water, too little water can cause plants to turn brown, as the foliage is unable to remain healthy and green when deprived of adequate amounts of water. The proper amount for your Swiss cheese plant will vary depending on the season, the size of the pot, and the soil you’re using, so it is important to monitor the moisture levels in the soil before you water. A good rule of thumb is that if the top few inches of the soil appear dry, it is likely time to water.
Fungal Infection
Fungal infections, such as root rot, are another common cause of yellow or brown spots appearing on the leaves of a plant. If the leaves of your Swiss cheese plant appear yellow and have eventually become brown and mushy, it is likely due to a fungal infection. To prevent this issue from happening, make sure that you’re using a soil with good drainage. You can also buy fungicidal sprays at most garden centers and use this as a preventative measure.
No homeowner or plant-lover wants their prized Swiss cheese plant to suffer from any kind of issue, especially one that can be as devastating as turning brown. Luckily, with a bit of knowledge and a bit of patience, the issue can likely be resolved with minimal effort. Whether the problem is too much or too little water, or a fungal infection, there are a number of solutions available to keep your Swiss cheese plant looking as healthy and green as Swiss cheese should be!
