Medlar

Medlar

Mespilus germanica

The Medlar is a deciduous tree or large shrub, typically reaching 3-6 meters (10-20 feet) in height. It's known for its unusual fruit, which is hard and unpalatable when freshly picked, requiring 'bletting' (a period of softening and slight decay) to become edible. It has attractive white flowers in late spring and develops interesting gnarled branches as it matures. The leaves turn reddish-brown in the fall, adding to its ornamental value. It is primarily grown outdoors for its fruit and ornamental qualities. It is not suitable for indoor cultivation due to its size and need for specific environmental conditions.

❓ Frequently Asked Questions — Comparing These Plants

Bachelor's Button

What are the light requirements for Bachelor's Button?

Bachelor’s Buttons require at least 6-8 hours of direct sunlight each day to thrive. Insufficient light can result in leggy growth, fewer blooms, and pale foliage. Choose a location in your garden that receives full sun throughout the day. If growing indoors, place them near a south-facing window where they can receive ample sunlight.

How do I care for Bachelor's Button?

Bachelor’s Buttons thrive in full sun and well-drained soil. Water regularly, especially during dry periods, but avoid overwatering to prevent root rot. Fertilize with a balanced, slow-release fertilizer in spring to encourage abundant blooms. Deadhead spent flowers regularly to promote continuous flowering throughout the season. These plants are relatively cold-hardy but may benefit from a layer of mulch in colder climates.

How do I propagate Bachelor's Button?

Bachelor’s Buttons are primarily propagated by seed. Allow some flowers to go to seed and collect the seeds once they are dry. Sow the seeds in spring or fall in well-drained soil. Keep the soil consistently moist until germination. Thin seedlings to ensure proper spacing.

Medlar

What are the light requirements for Medlar?

Medlar thrives in bright, indirect sunlight when grown indoors. Insufficient light can lead to leggy growth and reduced flowering and fruiting. A south-facing or east-facing window is ideal. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure on all sides.

How do I care for Medlar?

Caring for Medlar as an indoor tree requires attention to several key factors. Ensure it receives bright, indirect sunlight. Water thoroughly when the top inch of soil is dry, allowing excess water to drain. Maintain moderate humidity levels. Use a well-draining potting mix. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer.

How do I propagate Medlar?

Medlar can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix. Keep the soil moist and provide high humidity. Roots should develop in 4-8 weeks.
