Sorbus Olympic Flame Problems

The Sorbus ‘Olympic Flame’ is a delightful tree, coveted for its stunning foliage and hardy nature. However, like all plants, it can sometimes face challenges. Below, we delve into a case where the tree showed signs of distress and explore potential solutions based on expert insights.

The Problem:

A Sorbus ‘Olympic Flame’ tree showcased vigorous growth during its first year after purchase. In the subsequent year, the tree flowered and was on the verge of leafing when cold weather struck. The leaves failed to open fully, and the tree appeared unhealthy throughout the year. In the third year, despite an initial flourish of flowers and budding leaves, cold winds caused the leaves to curl up, and there was no new growth even after temperatures rose. Although the tree is not dead, its branches remain leafless.

Potential Causes and Solutions:

  1. Watering Needs: Sorbus trees require significant amounts of water, especially during their establishment phase.Solution: Ensure that the tree receives consistent and adequate watering. Regularly check the moisture levels of the soil, especially during dry spells.
  2. Exposure to Wind: While the tree in question wasn’t in an exposed site, being situated close to a fence might make it susceptible to dryness due to the wind.Solution: Protect the tree from strong winds, which can quickly dry out plants. Consider relocating it if it’s in a particularly wind-prone area.
  3. Planting Site Conditions: The vicinity of a fence can result in drier conditions, and the presence of nearby plants can lead to competition for moisture.Solution: Ensure the tree has sufficient space and is not crowded out by other plants or structures that may affect its water supply.
  4. Soil Quality: Sorbus trees favor well-draining soil. In this case, the garden is described as a bog with wet clay, which may lead to poor drainage and root rot.Solution: Improve soil conditions by incorporating organic matter or sand to enhance drainage. If the garden is particularly boggy, consider installing a drainage system. Moreover, when replanting, dig a sizeable hole, add water to test drainage, and use supplements like blood fish & bone to enrich the soil.
  5. Planting Practices: Planting directly into grass may not be ideal as grass can compete for essential nutrients and water. Also, clear space around the tree can prevent weed interference.Solution: When planting or replanting the tree, ensure it’s set in a weed-free zone. Remove grass and other competing plants around its base.
  6. Tree Health: The overall health and quality of the tree upon purchase play a crucial role in its subsequent growth.Solution: Always buy plants and trees from reputable nurseries. If a tree appears unhealthy or distressed, consult with experts or consider replacing it.

Conclusion:

The Sorbus ‘Olympic Flame’ is a resilient tree, but like all plants, it has specific needs. By ensuring the right soil conditions, adequate watering, and protection from extreme elements, gardeners can enjoy the beauty and elegance of this tree for many years. If in doubt, seeking expert advice or insights from more experienced gardeners can be invaluable.
