Peace Lily Disease Symptoms And Causes
The symptoms of Peace Lily disease are very similar to those of other common diseases like Phytophthora infestans (brown spots), Pythium blight (yellow spots) or Fusarium wilt (white blotches). However, unlike these other diseases, Peace Lily disease does not affect only one plant at a time but affects all your plants in the same season.
Peace Lily disease usually starts when a single plant becomes infected by Peace Lily spores. These spores may be carried from one plant to another through wind, rain, water droplets or even dust particles. Once they enter the soil where your plants grow, they will germinate and start growing into new Peace Lilies. They may also spread by insects such as aphids or mealybugs which feed on the roots of your plants.
It is not uncommon for Peace Lily disease to occur in the springtime. If it occurs during summer, then it means that there was too much rainfall in the previous winter. You need to reduce watering your plants if you want them to survive this year. Also, try to keep your plants away from strong winds because they could carry the Peace Lilies spores further. If the disease occurs during fall or winter, then it is probably because you did not give enough water during these seasons.
It is also important to note that Peace Lilies are a favorite breeding ground for several insects such as aphids and mealy bugs. These feed on your plant by sucking its nutrients. Unsurprisingly, they can carry the Peace Lily disease and spread it from one plant to another. To keep your plants away from these insects, you can spray some insecticide routinely.
Once your plants are infected by Peace Lily disease, they will not recover easily. In the best case scenario, they will survive for one more year and will be very weak. If the infection is too severe, then the plant will die. In any case, the infected plant will no longer be attractive to look at. This is why it is important to treat your plants immediately once you notice any symptoms.
Treating Peace Lily Disease
Once your plant shows any sign of Peace Lily disease, you need to act immediately. If the infection is not too severe, then you can easily save the plant by following the steps below:
1.Remove and discard all the infected leaves from the plant. Be very careful not to touch the leaves with your bare hands because they can infect other plants as well.
2.Spray some fungicides on the remaining part of the plant. Make sure that you choose a product which contains nothing harmful for the environment, otherwise it may affect your other plants as well.
3.Destroy all the infested soil in your garden with a garden trowel and replace it with new soil. Do not forget to disinfect the trowel with a fungicide before and after using it.
If you do not have the time or the patience to follow these steps, then you may want to hire an expert. These people know all the tricks of the trade which can save your plants.
How To Prevent Peace Lily Disease
The best way to prevent Peace Lily disease is by following the steps listed below:
1.Always be on the lookout for any sign of infestation. Check your plants routinely for insects, fungus and other possible signs of infection such as wilting leaves.
2.Keep an eye on the weather. Peace Lilies are particularly susceptible to root and stem rot when there is too much water. They are also prone to fungal infections when there is too much moisture in the air.
3.Make sure that you choose the right location for planting your Peace Lilies. If you live in a tropical or sub-tropical climate, then it is best to keep your plants away from doors and windows. Also, avoid basements because they tend to remain moist all year round.
4.If you do notice any sign of infection, move the plant away from other plants immediately. Do not add the infected soil to your compost pile or throw it in the garbage! You must get rid of it by burning it. At this point, it is much safer to get a new plant rather than try to save the old one.
5.Apply some mulch around the base of your plant to maintain optimum moisture levels in the soil.
6.Fertilize your plant periodically with all-purpose fertilizer.
7.If you see any insects on your plant, do not use insecticide. The best way to get rid of these little critters is by using your own hands. It is best not to introduce any more chemicals into your garden if you can avoid it.
How To Get Rid Of Peace Lilies Permanently
If you have tried everything in your power to get rid of the disease, yet the plant still shows no sign of recovery, then you may want to remove the entire plant from your property and replace it with a new one.
If you have other plants in your garden, then it is best to take a few preventative measures such as quarantining the new plant. This prevents the spread of any possible disease that may be harbored by the new plant.
Also, do not plant the new plant too close to your other plants to prevent the spread of any possible disease that it may harbor.
