Medlar (Mespilus germanica) is an ancient fruit-bearing tree that dates back to the Roman times, cherished for its unique flavor and ornamental beauty. Though not commonly cultivated in the United States, growing medlar in Kentucky can be a rewarding experience for home gardeners. With the right conditions and care, you can enjoy this exotic fruit while adding diversity to your garden. This article will guide you through the process of growing medlar in Kentucky, covering everything from site selection to harvesting.
Before diving into the specifics of cultivation, it’s essential to understand what medlar is and its requirements. Medlar trees are deciduous, typically reaching heights of 15 to 25 feet. They feature white flowers in spring, followed by small, brownish fruits that mature in late spring to early summer. The fruits require a unique ripening process known as “bletting,” which can be a new concept for many growers.
Medlar trees thrive in full sun but can tolerate partial shade. For optimal growth and fruit production, select a site that receives at least six hours of direct sunlight daily. This ensures that the tree will photosynthesize effectively and develop healthy fruit.
Medlar prefers well-drained soil with a pH between 6.0 and 7.5. Although it can adapt to various soil types, sandy loam is ideal. Conduct a soil test before planting to determine pH and nutrient levels. If your soil is too acidic or alkaline, amendments may be necessary to create an optimal growing environment.
When planting medlar, consider the mature size of the tree. Provide adequate spacing—at least 15-20 feet between trees—to promote good air circulation and reduce competition for nutrients. This spacing will also help minimize disease spread.
The best time to plant medlar trees in Kentucky is during the early spring or fall when the weather is cooler. Transplanting in these seasons allows the tree to establish its root system before facing the heat of summer or the cold of winter.
Digging the Hole: Create a hole that is two to three times wider than the root ball but only as deep as the root ball itself. This encourages lateral root growth.
Soil Enrichment: Amend the excavated soil with organic matter such as compost or well-rotted manure to improve drainage and nutrient content.
Positioning: Place the tree in the center of the hole, ensuring that the graft union (the area where the tree variety was grafted onto rootstock) sits at soil level.
Backfilling: Fill in around the root ball with native soil mixed with your organic amendments, making sure there are no air pockets.
Watering: After planting, water thoroughly to help settle the soil around the roots.
Young medlar trees require consistent moisture until they are established. This means watering them once or twice weekly during dry spells, especially in their first two years. Once established, medlars become drought-tolerant but should still be watered during prolonged dry periods.
While medlar trees are relatively low-maintenance regarding fertilization, an annual application of balanced fertilizer in early spring can promote healthy foliage and fruit production. A nitrogen-rich fertilizer is particularly beneficial during the tree’s early years.
Pruning is essential for maintaining a healthy structure and encouraging fruit production:
Timing: Prune during late winter or early spring before new growth begins.
Technique: Remove dead or damaged branches and any that cross over each other to open up the center for better air circulation.
Shaping: Aim for an open-center shape, which allows sunlight to penetrate throughout the canopy while supporting a sturdy structure.
Fruit Thinning: During heavy fruiting years, thin out some fruits to enhance size and quality.
Medlar trees are generally resistant to pests and diseases but can still be susceptible to certain issues:
Fungal Diseases: Look out for signs of leaf spot or powdery mildew. Good air circulation helps prevent these diseases, but if they occur, treat with fungicides as necessary.
Insect Pests: Aphids and scale insects may occasionally infest medlar trees. Regularly inspect your trees for signs of infestation and use insecticidal soap or horticultural oil if needed.
One of the most exciting aspects of growing medlar is harvesting its unique fruits:
Medlar fruits turn brownish-yellow when they are ripe but need to undergo bletting—a process where they soften after being harvested and exposed to frost or stored in a cool place for several weeks. Once bletted, they develop a sweet flavor reminiscent of applesauce or cinnamon.
Timing: Begin harvesting when fruits have reached their brownish-yellow color but are still firm.
Method: Gently twist or cut the fruit from its stem without damaging surrounding fruit or branches.
Fresh medlar fruits can be eaten raw once they have undergone bletting, but they can also be used in various culinary applications:
Growing medlar in Kentucky offers gardeners a chance to cultivate a unique and historical tree that contributes both beauty and delicious fruit to their landscape. With proper site selection, care techniques, and an understanding of its needs, you can successfully grow this ancient fruit tree while delighting in its ornamental traits and culinary versatility.
By incorporating medlar into your gardening repertoire, you not only diversify your landscape but also enrich your culinary experiences with this exceptional fruit—an effort worth undertaking!
