Now, let’s delve into each of these aspects to gain a deeper understanding of how to care for lamb’s ear effectively.



Lamb’s ear is a versatile plant with various practical and aesthetic uses in garden and landscape settings. Its soft, velvety leaves and low maintenance characteristics make it a popular choice for the following purposes:

  • Ground Cover: Due to its dense growth habit and spreading nature, lamb’s ear is commonly used as a ground cover plant in sunny to partially shaded areas.
  • Border Plant: The low-growing and mounding form of lamb’s ear makes it an excellent border plant, defining pathways and garden beds with its unique foliage.
  • Erosion Control: Its extensive root system and spreading growth make lamb’s ear an effective solution for preventing soil erosion on slopes and banks.
  • Cut Flower Arrangements: The attractive foliage and occasional flowering spikes make lamb’s ear leaves a popular choice for adding texture and contrast to cut flower arrangements.


Lamb’s ear exhibits moderate drought tolerance once established, but it thrives best in consistently moist soil. Here are some specific watering guidelines to ensure the optimal health of your lamb’s ear plants:

  • Establishment: Newly planted lamb’s ear should be watered regularly to promote root establishment. Provide sufficient water to keep the soil consistently moist but not waterlogged for the first few weeks after planting.
  • Established Plants: Once the plant is established, it typically requires water when the soil becomes dry to a depth of about 1 inch. During hot and dry periods, regular watering may be necessary to prevent wilting.


Lamb’s ear prefers full sun to partial shade, thriving in locations with at least 6 hours of direct sunlight per day. Here are some important considerations regarding sunlight exposure for lamb’s ear plants:

  • Full Sun: In regions with cooler climates, lamb’s ear can tolerate full sun exposure well. However, in hotter climates, some afternoon shade may be beneficial to prevent leaf scorching.
  • Partial Shade: If grown in excessively hot regions, providing partial shade during the peak afternoon hours can help protect the plant from heat stress and maintain its attractive foliage.


Lamb’s ear is not a heavy feeder and generally thrives in moderately fertile soil. Applying a balanced, slow-release fertilizer once a year in the spring can help maintain the plant’s vigor and foliage quality. Consider using a 10-10-10 or 12-12-12 fertilizer or a comparable organic alternative.

Fertilization Guidelines

  • Application: Apply the fertilizer around the base of the plant, avoiding direct contact with the foliage, and lightly work it into the soil surface.
  • Dosage: Use the fertilizer according to the recommended dosage on the product label. Avoid over-fertilizing, as excessive nutrients can lead to rapid, succulent growth and decreased drought tolerance.


Lamb’s ear thrives in well-draining soil with a slightly alkaline to neutral pH. Good soil drainage is crucial for preventing root rot and maintaining the plant’s overall health. When planting or transplanting lamb’s ear, consider the following soil requirements:

  • Soil Type: Sandy loam or loamy soil with good drainage is ideal for lamb’s ear. Heavy clay soils should be amended with organic matter like compost to improve drainage and aeration.
  • Soil pH: Lamb’s ear prefers a soil pH ranging from 6.6 to 7.8. Conduct a soil test to determine the pH of your planting area and amend the soil if necessary to achieve the optimal pH level.


Pruning lamb’s ear is mainly focused on removing spent flower spikes and controlling its spread to maintain a tidy appearance. Here are some specific pruning guidelines for lamb’s ear plants:

  • Deadheading: After the flowering period, remove the spent flower spikes to promote continued leaf growth and prevent self-seeding, especially if you want to limit its spread.
  • Spring Cleanup: In early spring, you can trim back any damaged or winter-killed foliage to encourage new growth and maintain the plant’s compact form.


Lamb’s ear can be propagated through division or stem cuttings to create new plants or rejuvenate existing ones. Here are the key propagation methods for lamb’s ear:

  • Division: Divide mature lamb’s ear plants in the spring or fall by digging up the entire plant and separating the root mass into smaller sections, each containing some roots and foliage.
  • Stem Cuttings: In the spring or early summer, take 3- to 4-inch cuttings from healthy stems, remove the lower leaves, and plant them in a well-draining medium to root.

Container Popularity

Lamb’s ear is a popular choice for container gardening, adding unique texture and visual interest to patio and balcony displays. When growing lamb’s ear in containers, consider the following factors:

  • Container Size: Choose a container with sufficient depth and width to accommodate the root system and prevent overcrowding. A 12- to 14-inch diameter container is suitable for a single lamb’s ear plant.
  • Drainage: Ensure that the container has adequate drainage holes to prevent waterlogging, as lamb’s ear is sensitive to waterlogged conditions.

Common Diseases

While lamb’s ear is generally resistant to pests and diseases, it can occasionally encounter specific issues that may affect its health and appearance. Some of the common diseases that may affect lamb’s ear include:

  • Leaf Spot: Fungal leaf spot diseases can cause circular or irregularly shaped brown spots on the leaves, leading to defoliation and reduced plant vigor.
  • Root Rot: Prolonged exposure to waterlogged soil can lead to root rot, causing wilting, yellowing foliage, and stunted growth.

Disease Diagnosis

Diagnosing and treating plant diseases promptly is crucial for preventing the spread of infection and ensuring the plant’s recovery. Here are some diagnostic and management tips for common lamb’s ear diseases:

  • Visual Inspection: Regularly inspect the foliage and stems for signs of discoloration, lesions, or abnormal growth patterns.
  • Cultural Practices: Ensure good air circulation around the plant, avoid overhead watering, and maintain proper soil drainage to reduce the risk of fungal infections.

Common Pests

Lamb’s ear is relatively resistant to most insect pests, but it can occasionally attract some common garden pests. The following pests may pose potential threats to lamb’s ear plants:

  • Aphids: These small, soft-bodied insects can cluster on the new growth and underside of the leaves, causing distorted growth and honeydew secretion.
  • Spider Mites: Spider mites are tiny arachnids that can cause stippling and yellowing of the leaves, leading to reduced photosynthetic capacity.

Botanist’s Tips

Botanists and plant enthusiasts often share valuable insights and tips for cultivating and enjoying lamb’s ear to the fullest. Here are some expert tips for growing and caring for lamb’s ear:

  • Companion Plants: Pair lamb’s ear with other low-maintenance perennials like coneflowers (Echinacea), lavender (Lavandula), and veronica (Veronica) to create harmonious and visually appealing garden beds.
  • Wildlife Attractor: The nectar-rich flowers of lamb’s ear attract pollinators such as bees and butterflies, making it a beneficial addition to wildlife-friendly gardens.
