Why Is My Poinsettia Plant Dying?

A wilting poinsettia plant is a sign of improper care and handling. To help the houseplant from wilting, you must identify the causes and take appropriate measures to fix them.

There are a lot of possible reasons behind the wilting of your poinsettia plant. Keep reading and find out which cause applies to your favorite plant. (Source: Lowa State University).

Drought Stress Due to Under-Watering

Inconsistent watering habit is the leading cause of a wilting poinsettia plant. Dry soil makes the plant leaves start curling and eventually drop if the condition persists.

A drought-like environment occurs due to not watering the poinsettia more often. It can also happen due to irrigating the houseplant lightly to make the topsoil moisten only.

Poinsettia is a tropical plant and needs moisture to develop beautiful foliages. Drought stress makes the leaves crispy and brown. But fixing the under-watering issue is too easy.

Inspect the moisture content level in a potting soil using a moisture meter (Check Best Deals on Amazon). If the soil is dry, consider soaking it with filtered water.

Allow the container to sit until excess water pass through the drainage holes. Provide ultimate poinsettia care and schedule proper watering routine.

Poinsettia Wilting Due to Overwatering

Be sure to keep the potting soil moist when growing an indoor poinsettia plant. But keeping the soil damp might hurt your favorite houseplant.

A damp environment usually drowns the roots and makes them susceptible to diseases. Root rot occurs when the plant is grown in an overly wet condition.

The rotten and damaged roots inhibit the effective absorption of water and vital nutrients from the potting soil. Leaves curling and wilting are the symptoms of an overwatered poinsettia.

So, how do you revive an overwatered poinsettia? Consider transplanting the houseplant to a brand new potting soil. But remember to inspect soil moisture before watering your poinsettia.

Water the indoor plant twice or thrice every month in summer and once in winter. Poinsettia plants use less water and nutrients in winter due to dormancy.

Improper Drainage Issues

Improper soil drainage is the leading cause of overwatering issues. Poinsettia plants do not use a lot of water when growing. The potting soil ends up taking a long time to dry out.

Another possible cause of drainage issues is the lack of drainage holes at the bottom of the growing container. Getting rid of excess water becomes challenging in the long run.

Most houseplant enthusiasts have the behavior of keeping the foil on the pot that the poinsettia came with it. The decorative foil inhibits the pot from draining excess water properly.

Be sure to remove the decorative foil on the pot to enhance proper draining. Check if the pot has decent drainage holes to facilitate better plant growth and prevent the overwatering issue.

Ensure the poinsettia plant is grown in potting soil with proper drainage. It gives the plant time to dry out between the watering sessions.

Peat-based potting soil (Check Best Deals of Amazon) is the best soil type for growing poinsettia plants. It has excellent drainage and aeration to prevent creating a damp soil condition.

Improper Lighting Routine

Improper lighting can kill your poinsettia plant over time. Poinsettia plants need to receive sunlight for about six to eight hours each day.

Low lighting results in slow growth and leggy stems formation. The issue occurs when the houseplant is grown in a dark room. The plant will begin to wilt and die in the long run.

Besides that, bright direct sunlight exposure may make your poinsettia plant droop and begin to wilt at some point. Direct sunlight exposure enhances faster water loss and leaf sunburn.

Change the current position on the plant pot to a region that receives bright indirect sunlight. It will help to avoid leaves scorching issues and plant wilting.

If you’re growing poinsettia plants in a dark room, consider Led Grow Lights (Check Best Deals on Amazon). Artificial lighting is also effective in preventing wilting issues and slow growth.

Exposure to Cold Weather

The poinsettia plant temperature requirement is about 65-70oF. The temperature condition allows the houseplant to develop beautiful flowers and foliages.

Any temperature below 50oF will make your poinsettia plant limp and die. Poinsettia plants do not thrive under freezing temperatures.

The poinsettia leaves will begin to shrivel up when exposed to cold weather. The low-temperature stresses occur during the winter months.

Be sure to keep your poinsettia plant away from areas that experience temperature fluctuations at home. Do not keep the plant near cold drafts, air vents, fireplaces, and heat ducts.

Get a digital thermometer (Check Best Deal on Amazon) to help in detecting indoor temperature drops. Besides that, it will help to maintain proper poinsettia temperature requirements.

Lack of Humidity

Poinsettia is a tropical plant that thrives in a warm and humid environment. The condition allows the plant to develop striking flowers and foliages.

But poinsettia plants are more popular in winter months when the environmental humidity is low. Dry air around the poinsettia plant can be problematic to its health and growth.

Low humidity makes the poinsettia leaves curl and become droopy. If the condition persists, the plant will begin to wilt and eventually dies.

Use an indoor humidifier (Check Best Deals on Amazon) to help in detecting the humidity changes. You can also consider misting the plant to increase the humidity level.

Fungal Diseases

Poinsettia plants are less vulnerable to diseases. But this does not imply that the houseplant is invincible to plant diseases. Most poinsettia plants tend to battle fungal diseases.

Fungal diseases are prevalent when the indoor plant is grown warm and moist environment. The condition makes the plant susceptible to root rot.

The golden rule is to isolate the plant from other houseplant collections. The technique helps to prevent the spreading of fungal disease.

Stems getting dark and leave fading are common signs of fungal disease. Some fungal diseases cause the leaves to curl up and die.

Treating fungal diseases on poinsettia plants is a nightmare. The best option is to create an indoor growing condition that does not support fungal growth.

Avoid overwatering the houseplant at all means. Use proper drainage soil and pot with drainage holes at the bottom to get rid of excess water.
