Having black tips on your peace lily leaves can be a very frustrating experience. But there are several things you can do to help prevent them from appearing. First, make sure that you have a proper watering system. Next, check for over-fertilizing and salt build-up. Lastly, keep an eye out for insects and biological blight.
Overfertilizing
Adding too much fertilizer to your peace lily can be detrimental to the plant. Over fertilizing the plant can cause nutrient toxicity, and may also burn the roots. In addition, the plant may end up with brown or yellow leaves and a nutrient deficiency.
The most obvious symptom of over fertilizing your peace lily is a lack of blooms. It is important to know that the plant needs nutrients, but it is not essential to have flowers. In fact, the plant can easily survive without them.
Peace lilies are an easy-care houseplant. They require little sunlight and can grow indoors. However, they do require fertilizer. During the growing season, it is important to fertilize your peace lily.
Peace lilies require nutrients, including nitrogen, phosphorus and potassium. You can add eggshells to the soil, which are good sources of calcium. Also, banana peels contain some nitrogen and phosphorus. However, these are not high-nutrient fertilizers.
Pythium
Generally, Peace Lilies are pest free but they can be affected by insects and fungus. When a pest infestation is found, it is best to remove the infected leaves and flowers to keep the plant healthy.
The first sign of blight on Peace Lilies is the development of small oval-shaped tan to reddish-brown spots on the flowers. Root rot, stem rot, and collar rot can also be caused by these infections. It is best to use a bactericide to combat the fungus. The preferred bactericide is copper sulfate.
In addition, root rot can be caused by overwatering. It is important to check the moisture level of the soil and make sure that the soil is properly drained. If the soil is too wet, it can promote harmful microbes that can cause root rot.
Biological blight
Biological blight on peace lily leaves can be a serious threat to these easy houseplants. This fungus can survive in the soil and is found in organic matter. It can cause wilting and yellowing of the leaves. It can also affect bulbs, roots, and fruits. It is important to identify this disease before it gets out of control.
This disease is caused by a fungus called Sclerotium rolfsii. It produces large hyphal cells that form a white fungal mat on the soil surface. The hyphae are 5-9 microns in diameter. These hyphae are spread by plant debris and animal feces.
In the early stages, the plant can be treated by repotting. The roots should be loosened and then the plant should be repotted in a larger pot. The plant should then be kept in a shady area.
Salt build-up
Keeping your peace lily in perfect condition can be tricky when the plant starts showing signs of problems. But, if you can identify the underlying cause of the problem, you will be able to save your plant.
A good first step is to check the plant’s water intake. You can do this by dipping your finger into the soil and determining how wet it is. You may need to use a soil moisture meter to determine how much moisture the soil needs.
If you notice a brown tip on your peace lily, you may have overwatered the plant. Overwatering is the number one cause of death in houseplants.
The other possible culprit is sunburn. If your peace lily is in a spot that receives plenty of sun, then it might be experiencing a leaf burn. To avoid this, place it in a shady location.
Spider mites
Whether you’re growing a Peace Lily in your home or outdoors, you may be noticing spider mites on the leaves. These tiny arachnids are a common pest on plants in landscapes around the world. If you’ve got an infestation, they can cause severe damage to your plants. Luckily, there are a few ways to get rid of spider mites.
To start, you’ll want to remove fallen leaves from the plant and clean the foliage. This will help remove dust and debris that can attract the pests. You’ll also want to clean the top layer of soil.
Once the foliage is clean, you can apply a small amount of liquid fertiliser to the plant. This should help encourage new growth.
If you’re dealing with an infestation, you can use insecticidal soap to kill the pests. You’ll want to apply this to the plant’s leaves at least weekly, and you can also smother large aphid colonies by using organic insecticidal soap.
