Why Would a Dieffenbachia Start Wilting?
When you have been lovingly and tentatively caring for your Dieffenbachia plant and ensuring its every need is met, only to one day see that your beloved plant is beginning to look worse for wear and is wilting.
Seeing your Dieffenbachia plant go through some health issues is pretty discouraging for you as its caretaker. If you own a Dieffenbachia and you are putting a lot of effort into your plant every day, only to have the plant start wilting and declining in health can really start to bring you down.
Unfortunately, multiple things can start to impact the health of your Dieffenbachia plants. With the number of possible ailments, it can be challenging to find out what is affecting your Dieffenbachia and if you can fix it or not.
Here are the main problems you could face with your Dieffenbachia plant that could cause the plant to wilt:
- Underwatering or overwatering your plant
- Nutrient deficiencies in the plant
- Temperature fluctuations in the plant environment
- Problems with pests attacking your plant
- Improper lighting conditions for the Dieffenbachia plant
Many of the problems that cause your Dieffenbachia to wilt can also cause your plant to have stunted growth, and some can eventually lead to the death of your plant if not treated immediately after you have noticed it.
Let’s look at all these problems more in-depth to see how you might fight them and possibly save your Dieffenbachia and avoid these issues in the future.
1 – Not Watering the Dieffenbachia Properly
Dieffenbachia plants are native to tropical climates and will suffer if it’s underwatered regularly. Underwatering your Dieffenbachia will cause your plant to become dehydrated, and it will start drying out.
This will cause your plant to droop or wilt as there is not enough sap in the plant to hold it up anymore. You can tell if your Dieffenbachia is underwatered by looking at the soil. If the soil is bone dry, your plant is most likely underwatered.
You should water your plant more regularly to fix this problem. Even though Dieffenbachia plants are tropical, they can still be overwatered too. This can cause your plant to wilt as the plant is basically drowning and can no longer absorb nutrients from the over-saturated soil.
Overwatering can also lead to other problems with your plant, like root rot, so it needs to be dealt with urgently. To fix this problem, you will need to replant your Dieffenbachia; while doing so, you should check the roots for rot.
If you see any rot, you should trim the affected roots off. Then place your repotted plant into the sun for an hour or two to help dry it out. Continue with a proper watering schedule for your plant—only water your plant when the top 2″ of soil is dry.
2 – Nutrient Deficiencies
Dieffenbachia plants are prone to certain nutrient deficiencies that can cause the plant to wilt and leave to turn yellow. The main causes for these deficiencies to due to the soil being too acidic or poor application of fertilizers to the soil.
The two nutrients that are likely to cause the wilting of your plant when there is not enough in the soil are phosphorous and nitrogen. When these two nutrients are lacking in the soil, it can begin to seriously affect your plant’s health.
To test if this is the cause of the wilting, you will need to do a soil test. If this is the cause, you will need to fertilize your Dieffenbachia plant with a fertilizer high in nitrogen and phosphorous, and you will need to treat the soil with lime to bring the soil’s acidity down.
3 – Temperature Fluctuations
Sudden temperature changes can affect your Dieffenbachia plant. This can be from cold or hot drafts coming through your home or a sudden thunderstorm that drops the temperature slightly.
Remember that these plants are from tropical climates and are not used to temperature fluctuations as they mainly live on the forest bed under a thick canopy of trees.
Dieffenbachia plants will thrive in the temperature range of 62°F to 80°F, and anything higher or lower will begin to affect their health, especially if it’s a sudden change.
To help fix and prevent this problem in the future, you need to keep your Dieffenbachia plant in its optimum temperature range. So, you will need to find a place in your home that matches these temperatures.
4 – Pest Problems
Pests can become a major problem for your Dieffenbachia plant if they become infested with them. The two pests that this plant is prone to attacks by are mites and aphids. These pests can cause serious harm to your plants and can cause your Dieffenbachia to wilt.
This is because these pests will eat the sap from your plant and cause it to dehydrate, among other problems. This will cause your Dieffenbachia plant to wilt and possibly even fall over. If you don’t treat these pests, they will eventually kill your Dieffenbachia plant.
You can help your plant rid itself of these pests by spraying it with a soapy water spray, and you can help prevent the pests in the future by spraying your plant with a neem oil spray.
5 – Improper Lighting Conditions
Dieffenbachia plants are naturally found under tree canopies, so these plants are not meant for direct sunlight. These plants only require bright indirect sunlight to survive, and if they receive any other type, they can develop a few problems.
If your plant receives too much sunlight or direct sunlight, it will begin to wilt under the heat and possibly be scorched. If they don’t receive enough sunlight, they will begin to wilt, but their leaves will turn yellow.
You need to keep your Dieffenbachia plant away from direct sunlight but in bright indirect sunlight for it to thrive. You can place your plant next to a window with a sheer curtain to protect it by allowing it to receive the light it needs.
Dieffenbachia plants are stunning plants with their somewhat mottled leaves and bright green color, making them popular houseplants. However, these plants can suffer from various problems that can begin affecting their health.
If you are concerned about the health of your beloved Dieffenbachia plant, go through the list of problems above, as it should help you figure out what is wrong with your plant. Good luck with your Dieffenbachia plant!
