Growing medlar (Mespilus germanica) in Alaska presents unique challenges and opportunities. This ancient fruit tree, prized for its unique flavor and historical significance, can thrive in specific conditions despite the cooler climate. With the right techniques and knowledge, Alaskan gardeners can successfully cultivate this intriguing tree. This article will cover everything you need to know about growing medlar in Alaska, from choosing the right variety to caring for your tree.
Medlar is a deciduous tree that can grow up to 15 feet tall, featuring beautiful white flowers in spring and distinctive brownish fruit that ripens in late spring to early summer. The fruit is unique because it must be bletted (overripe) before it’s palatable, leading to its intriguing taste reminiscent of applesauce mixed with a hint of spice.
While medlar may not be as well-known as other fruits, it has a rich history dating back to ancient Rome. Today, it is gaining popularity among fruit enthusiasts and organic gardeners due to its hardiness and intriguing flavor.
When cultivating medlar in Alaska, selecting the right variety is crucial for success in the region’s cooler climate. While Mespilus germanica is the most commonly grown species, consider looking into different cultivars that adapt well to colder temperatures.
Dutch Medlar: Known for its cold hardiness, the Dutch medlar can withstand harsh winter conditions, making it an excellent choice for Alaskan gardens.
Rosenmond: This early-flowering variety produces sweet fruits and is known for its resistance to diseases, making it a reliable option for novice gardeners.
Nottingham: Slightly larger than other varieties, Nottingham produces flavorful fruit with high yields. It may be a bit less hardy but can still succeed with proper care.
Medlar trees can be sourced from specialty nurseries or online retailers specializing in rare fruit trees. Ensure the plants you choose are healthy and ideally suited for your growing zone.
Alaska’s climate can vary significantly depending on the region. Medlar trees prefer a temperate climate with cool winters and moderate summers. They are generally hardy in USDA zones 5-9; however, microclimates within Alaska may allow for successful growth in certain areas.
Medlar trees thrive in well-draining soil that is rich in organic matter. They prefer slightly acidic to neutral pH levels (around 6.0 – 7.0). Before planting:
Medlar trees need full sun exposure for optimal growth and fruiting. Aim to provide at least 6-8 hours of sunlight each day. In Alaska’s long summer days, this should not be an issue; however, be mindful of shading from nearby structures or trees.
The best time to plant medlar trees in Alaska is during early spring when the risk of frost has passed, or early fall before the first hard freeze. This timing allows the roots to establish before facing temperature extremes.
Select Your Location: Choose a site that receives ample sunlight and has good drainage.
Prepare the Planting Hole: Dig a hole that is twice as wide and as deep as the root ball of your medlar tree.
Soil Amendments: Mix compost or well-rotted manure into the soil you remove from the hole to enhance fertility.
Planting: Place the tree in the center of the hole with its root crown level with or slightly above soil grade. Fill in around the roots with amended soil and water thoroughly.
Mulch: Apply a layer of mulch around the base of the tree (but not against the trunk) to help retain moisture and suppress weeds.
During their first year, medlar trees require consistent watering to establish deep roots. Once established, they are fairly drought-tolerant but will benefit from supplemental watering during dry spells—especially during fruit development periods.
Fertilize medlar trees annually in early spring using a balanced organic fertilizer to promote healthy growth and fruit production:
Pruning is essential for maintaining tree health and shape:
Regular pruning enhances sunlight penetration and encourages better fruit production.
Though relatively pest-resistant, medlar trees may encounter some issues:
Aphids: Small green insects that suck plant sap; treat with insecticidal soap if needed.
Scale Insects: Hard-shelled pests that adhere to branches; regular pruning can help manage infestations.
Fruit Flies: Can affect ripening fruit; use traps if necessary.
Medlar trees are susceptible to fungal diseases like powdery mildew or leaf spot:
Medlars require special attention when it comes time for harvest:
Bletting Process: As mentioned earlier, medlars must undergo bletting—the overripening process—before they are edible. Wait until they turn brownish and soft.
Harvest Timing: Depending on local climate conditions, harvesting typically occurs from late summer through early fall.
Storage: The bletted fruit can last several weeks when stored properly in a cool place or refrigerated.
Growing medlar in Alaska may require some extra effort due to the unique weather conditions but can yield delicious rewards for those who embrace this charming fruit tree. With careful selection of varieties adapted for colder climates, proper planting techniques, diligent care throughout its growing season, and attention to harvesting methods, any Alaskan gardener can enjoy this historical fruit right from their backyard garden!
By following these guidelines on how to grow medlar effectively despite climate challenges, you can experience both success in your gardening endeavors and add an exciting new fruit variety into your culinary repertoire!
