Taste

The Strawberry Tree (Arbutus unedo), also known as the Killarney strawberry tree or Irish strawberry tree, produces small, round fruits that are often likened to strawberries in appearance. The taste, however, is unique—sweet but mild, with a subtle hint of tartness. The texture is slightly grainy, similar to that of a fig, and the fruits are typically enjoyed fresh, though they are also used in jellies, jams, and liqueurs.

Best Growing Environment

The Strawberry Tree thrives in Mediterranean climates but is also well-adapted to temperate regions. It prefers well-drained, slightly acidic to neutral soils (pH 6.0-7.0) and can tolerate poor soil conditions. This hardy tree flourishes in areas with mild, wet winters and hot, dry summers. It is also adaptable to coastal environments and can withstand salty conditions, making it suitable for seaside plantings.

Common Names

  • Arbutus unedo

Average Height

Strawberry Trees typically reach an average height of 15 to 30 feet (4.5 to 9 meters), with a spread of about 10 to 15 feet (3 to 4.5 meters). The tree has a bushy, rounded shape with a dense canopy of glossy, dark green leaves.

Growth Rate

The growth rate of the Strawberry Tree is moderate, with an annual growth of about 12 to 24 inches (30 to 60 cm). The tree's growth can be influenced by environmental conditions and care practices, such as proper watering and fertilization.

Sun Requirements

Strawberry Trees prefer full sun to partial shade. They require at least 6 hours of direct sunlight each day to thrive, although they can tolerate some shade, especially in hotter climates where afternoon shade can protect the tree from excessive heat.

Cold Hardiness

The Strawberry Tree is hardy to USDA zones 7 to 10. It can tolerate temperatures down to about 10°F (-12°C) but may suffer damage in prolonged or severe freezes. In colder regions, it is best to plant the tree in a sheltered location and provide frost protection during the winter months.

Water Requirements

Strawberry Trees are drought-tolerant once established but benefit from regular watering, especially during dry spells. Young trees should be watered deeply once or twice a week until they are established. Mature trees need less frequent watering but will produce better fruit if given consistent moisture. Mulching around the base of the tree helps retain soil moisture and reduce evaporation.

Planting Guide

  1. Site Selection: Choose a location with full sun to partial shade and well-drained soil. Ensure there is enough space for the tree to reach its mature size without crowding other plants or structures.
  2. Soil Preparation: Amend the soil with organic matter such as compost to improve fertility and drainage. Dig a hole twice the width of the root ball and just as deep.
  3. Planting: Place the tree in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill with soil, gently firming it around the roots to remove air pockets. Water thoroughly after planting.
  4. Mulching: Apply a 2 to 3-inch (5 to 7.5 cm) layer of mulch around the base of the tree, keeping it away from the trunk to prevent rot. Mulch helps retain moisture and suppress weeds.
  5. Staking: Young trees may benefit from staking to provide support and encourage straight growth. Use flexible ties and avoid damaging the trunk.

Detailed Fertilizing Guide

  1. First Year: Fertilize young Strawberry Trees in early spring and mid-summer with a balanced, slow-release fertilizer (such as 10-10-10). Follow the manufacturer's instructions for application rates based on tree size.
  2. Second Year Onward: Apply fertilizer twice a year—in early spring and mid-summer. Use a balanced fertilizer (10-10-10) or one with a higher potassium content (5-5-10) to support growth and fruit production.
  3. Fruit Development: During the fruiting season, switch to a fertilizer with a higher potassium content to enhance fruit quality and yield. An example would be a 5-5-20 fertilizer.
  4. Organic Options: Organic fertilizers such as compost, well-rotted manure, or fish emulsion can be used to provide a steady supply of nutrients.
  5. Micronutrients: Apply a micronutrient spray containing zinc, manganese, and iron periodically to address any potential deficiencies and promote overall tree health.
