There are many reasons why an indoor plant’s leaves appear dark and dingy. Some of them are caused by insects, while others are caused by fungus. If insects are the culprit, you can treat your plant manually using insecticidal soap. Fungus problems can also be treated with a fungicide. However, it’s more effective to remove the diseased tissue than to try to treat it with a fungicide.
Watering too much
Watering your indoor plant can cause its leaves to brown, but there are a few ways to avoid this. First, don’t water too deeply. Watering too shallowly will only moisten the top layer of soil, leaving the roots unaffected. This will also cause water to evaporate. Watering your indoor plant should be done in a manner that allows for optimal root development. This will also prevent brown leaf tips, which are a sign of root damage.
It’s important to check the soil regularly if you want to ensure the health of your indoor plant. Don’t use tap water, as it contains chlorine and other harmful chemicals that can burn your indoor plant’s leaves. Instead, use distilled or filtered water, which has a neutral PH.
If the leaves of your indoor plant turn brown, you should consider trimming them with scissors. Pulling off entire leaves can cause further damage and leave your plant susceptible to disease.
Aphids
Aphids are a common pest for indoor plants. These tiny, green insects cluster on tender new growth and feed on plant juices. Their presence will cause the leaves to turn a dingy brown or yellow. The good news is that aphids are fairly easy to remove. If you notice them on your plants, remove them by rubbing the leaves with a hose or sink sprayer. You can also try applying insecticidal soap or neem oil to the infested areas.
If you’re unable to remove the aphids by hand, try using diatomaceous earth on the affected leaves and flowers. Do not use this product on the flower petals since it may harm the beneficial insects. Try to spray the plant leaves every two or three days for about a week.
Aphids can cause serious damage to your plants. They feed on plant sap and excrete a sugary substance called honeydew. This substance attracts other insects, such as ants, which eat it. They can also cause sooty mold on your plants, resulting in blackened leaves. Aphids also cause distorted flowers and leaves. Some species even cause galls and can transmit viruses from plant to plant.
Root rot
If your indoor plants have dark leaves and mushy roots, it’s possible that you’re dealing with root rot. The good news is that you can treat it easily! You’ll need sterilized scissors, new potting soil, bleach, and fungicide. You’ll also need to wash the rotting roots under running water. Once you’ve done this, you’ll be able to trim the roots.
One of the first signs of root rot is the smell of decay. It’s usually very faint at first, but it will get stronger as the disease progresses. Healthy roots have a distinct earthy smell. In advanced stages, the roots have turned to mush and may even fall off the plant. If you’re unable to prevent the root rot from progressing further, you should repot the plant and remove the affected soil. If the roots are completely destroyed, you should remove the plant and place it in a slightly drier spot.
If you can’t get rid of the rotted leaves immediately, you can try pruning the plant’s leaves to encourage new root growth. You can also try removing the damaged soil and discarding it in the trash. However, you should not compost the rotted roots as the risk of pathogen contamination is high. To reduce the risk of spreading disease, you should sterilize all tools and pots. You should also wash them with a bleach solution.
Over-fertilization
Plants can become over-fertilized without realizing it, and it can have negative effects on their growth. Fortunately, there are ways to remedy over-fertilization, such as soil flushing. For the easiest method, you can use pots with drainage holes and run a continuous flow of water around the pots to flush out the excess fertilizer.
Before you use fertilizer, it is essential to test the soil in the plant’s pot to determine the right amount of feed. You can perform a home test or a professional analysis to find out the exact nutrients your plants need. Never fertilize a plant unless you do a soil test first. It’s also important to know when to stop fertilizing your indoor plants with dark leaves. In addition, your plant’s growth rate will depend on the size of the pot and the volume of soil it has. Similarly, light intensity plays a big role in plant growth.
The first sign of over-fertilization is a plant with discolored leaves. The discolored leaves can be caused by fertilizer burn, which begins at the edges and then spreads to the entire leaf. Once the leaves become discolored, they may fall off or die. As a result, fewer leaves will grow and your plant will be less able to absorb light. The roots of your plant may also be damaged, which can stunt its growth and even kill it.
