Water-soaked black and brown spots on plant leaves and stems often indicate a fungal or bacterial disease is the problem. Adjust the watering schedule and do not allow plants to sit in excess water. That alone is enough to stop the progress of the disease. Fungal infections can be caused by a variety of fungi and bacteria, but the most common cause is a fungus called Phytophthora infestans.
This fungus thrives in warm, moist conditions, and it is often found growing on decaying organic matter, such as leaves, stems, or wood. It can also be found on plants that have been in contact with water or soil that has been contaminated with sewage or animal waste. If you suspect that your plant is infested with this fungus, contact your local public health department for more information.

Should I cut off leaves with brown spots?
If you see dead leaves or brown parts of leaves, cut them away. Don’t pull too hard, or you may damage the healthy part of your plant, when plucking dead leaves or stems with your hands. If you want to remove brown leaf tips and edges, use scissors or tweezers.

How do you treat leaf spots on houseplants?
Pick off leaves with spots and destroy them. Reducing humidity, decreasing leaf wetness, and increasing air circulation will help to reduce the severity of the infection. If your plant shows signs of infection, you should contact your local county health department.

How often should indoor plants be watered?
Houseplant’s potting soil should be kept moist, but not wet. They need less watering in the fall and winter than they do in the spring and summer. Plants should not be allowed to dry out between waterings.
If the soil is too dry, the plant will not grow well and may die. It is best to water the plants every other day. Watering too often can cause the roots to rot and the leaves to wilt.
Can plants recover from leaf spot?
Once a leaf is infected and damaged by leaf spot diseases, it will not recover or turn green again. The leaf is killed by the diseases. Deficiency trees put out new leaves on a regular basis and this isn’t usually a problem. However, for evergreens and conifers, this can be a serious problem. First, look at the leaves.
If they are yellow or brown, then it is likely that the tree has a disease. Look for signs of disease, such as dead or dying leaves, brown spots on the bark, or discolored bark. Third, if you see any of these signs, contact your local Extension office for more information.
What causes brown spot plants?
Sunlight damage is the most common cause of spots in plants. If your plant has been in a shaded position, you can eliminate sunburn as the reason for the spots. They are most likely due to an infectious disease.
If you suspect that your houseplant has spots, you will need to take it to your local garden center for a thorough examination. If the spot is not caused by a fungus or bacteria, it may be a sign of a more serious problem, such as an insect infestation.
Do brown tips on plants go away?
The brown leaf tips will not turn back to green but you can trim the brown edges to get the plant back to looking healthy. If you have a lot of browned leaves on your plant, you may need to water it more often. This is because the leaves will dry out faster if you water them too much.
You can use a watering can with a small hole in the bottom to catch the water. If you don’t have one of these watering cans, just fill a bucket with water and fill it up to the top of the can. Place the bucket in a sunny spot and let it sit for a couple of hours. It will be ready to use again.
What does bacterial leaf spot look like?
In some cases, the center of the leaf spot will dry up and fall out, giving the leaf a reddish-brown appearance. Leaf spots are caused by a fungal pathogen called Candida albicans, which lives on the leaves of many plants, including tomatoes, peppers, cucumbers, eggplants, and many other vegetables and fruits.
The fungus thrives in warm, moist environments, such as in the soil, but it can also thrive in cooler, drier conditions. When the fungus infects a plant, it causes the plant’s leaves to turn yellow and eventually fall off, leaving behind a white, waxy coating. This white coating is called a “leaf spot” because it resembles the appearance of a leaf.
Leaf spots can be very small, as little as a few millimeters in diameter, or as large as several centimeters. They can appear on any part of your plant and are usually harmless. However, if they are large enough, they can cause damage to your plants. If you notice a large number of leaf spots in your garden, you may want to consider removing the affected plants to prevent further damage.
