Arum lilies, also known as calla lilies, are elegant and stunning plants native to Africa, known for their distinctive flowers and long-lasting blooms. These captivating flowers can become the centerpiece of any garden or landscape. However, just like any other plant, arum lilies can experience difficulties, and one common issue gardeners face is drooping leaves and stems.

In this article, we will explore the possible reasons behind drooping arum lilies and discuss solutions to keep your plants healthy, vibrant, and standing tall. Whether you’re a seasoned gardener or just beginning your journey with arum lilies, you’ll find valuable insights to help restore and maintain the beauty of these captivating blooms.

Identifying Arum Lily Drooping

Common Signs and Symptoms

Recognizing the signs of arum lily drooping is crucial for taking timely corrective measures and maintaining the health of your plant. Some common symptoms to look out for include:

  • Limp, wilting leaves and stems
  • Yellowing or browning of leaves
  • Root rot or fungal growth near the base of the plant
  • Uneven growth or stunted development

It is worth noting that drooping can be caused by a variety of factors such as excessive moisture, poor drainage, or inadequate care. For example, while arum lilies thrive in moist soil, oversaturation may lead to limp stems and root rotting due to excessive rainfall or overwatering (Gardener’s Path).

Another possible cause could be suboptimal planting conditions. Ideally, arum lilies should be spaced 16 inches (40 cm) apart to ensure proper growth and development (Gardening Champion). Sudden changes in temperature may also affect the lilies, as they are sensitive to both hot and cold drafts.

In addition to the above-mentioned factors, proper care and maintenance play a significant role in preventing arum lily drooping. Ensure that your arum lilies receive adequate sun exposure, are watered regularly without overwatering, and are fed with appropriate nutrients to foster healthy growth.

Causes of Arum Lily Drooping

Watering Issues

Drooping Arum Lily leaves can indicate problems with their root system, often caused by too much or too little moisture in the soil. Overwatering or saturated soil can lead to limp stems and root rot, while underwatering can cause the plant to droop due to lack of hydration. To maintain the correct moisture level, ensure proper drainage and avoid overwatering or underwatering.

Lighting and Temperature

Arum Lilies can suffer from leaf discoloration, turning yellow or brown, as a result of too much sun or wind exposure. To prevent this, move your plant to a partial shade location. Additionally, sudden changes in temperature can negatively impact the plant’s health, so it’s essential to keep Arum Lilies in a stable temperature environment.

Nutrient Deficiencies

Inadequate nutrients can also cause drooping in Arum Lilies. Be sure to provide the necessary fertilizer to maintain the plant’s health and vigor. Regularly monitoring your plant’s health and adjusting your fertilizer regimen accordingly will keep your Arum Lily healthy and happy.

Pests and Diseases

Pests such as spider mites can lead to drooping Arum Lily leaves, as they feed on the plant’s foliage. Check your plant for any signs of infestation and treat them accordingly. Additionally, Arum Lilies can be affected by diseases like Phytophthora Richardiae, which causes root rot. To combat this, remove any infected parts of the plant, clean the corms, and repot them in fresh soil after washing them in a solution like Jeyes fluid.

Prevention and Treatment

Proper Watering Techniques

Arum lilies prefer moist soil but can suffer from drooping if the soil is oversaturated due to excessive rainfall, poor drainage, or overwatering. To prevent this issue, make sure to water your plants moderately and check the soil’s moisture levels consistently. If you notice puddles or signs of compacted soil, consider adding organic matter or perlite to improve drainage (Gardener’s Path).

Optimal Lighting and Temperature Conditions

Arum lilies grow well in warm climates, with temperatures ranging between 0.5 and 1.5 meters. Place your plant in a bright area with indirect sunlight, as direct sun exposure can cause the leaves to wilt. Ensure your plants are not exposed to sudden shifts in temperature or drafts, as these can cause drooping leaves.

Fertilizer Recommendations

Feeding your arum lilies with a balanced, slow-release fertilizer will help them grow strong and healthy leaves. Apply the fertilizer according to the package instructions during the growing season. Avoid over-fertilizing, as this can cause weak, drooping leaves.

Pest and Disease Control

Arum lilies can be affected by pests and diseases, which can lead to drooping leaves. For pest control, regularly check for signs of aphids, whiteflies, or spider mites, and treat affected plants with insecticidal soap or neem oil. If your plant is suffering from root rot or other diseases like Phytophtora Richardiae, you can take some preventive steps, such as removing the affected parts, washing the corms in a solution like Jeyes fluid, and repotting them in clean soil (Grows on You).


In summary, there are several factors that can lead to a drooping arum lily. These may include inadequate or excessive moisture in the soil, improper care, and diseases like Phytophtora Richardiae or root rot.

It is crucial to monitor the soil conditions to ensure that it is neither too dry nor oversaturated. In addition to maintaining proper watering routines, providing adequate drainage is necessary to prevent root rotting and other potential issues.

To prevent diseases, remove any unhealthy or dead foliage and take appropriate measures to treat the affected plant parts. By following good gardening practices and ensuring the overall health of your arum lily, you can help prevent drooping and ensure a thriving and beautiful plant.
