Goldenrain Tree:


  • The Goldenrain Tree (Koelreuteria paniculata) is a deciduous ornamental tree known for its vibrant yellow flowers in late spring and interesting seed pods.
  • It belongs to the Sapindaceae family and is native to East Asia.

Geographic Range:

  • The Goldenrain Tree is native to China and Korea but has been widely planted in various parts of the world as an ornamental tree.
  • It is suitable for USDA hardiness zones 5 to 9.

Growing Conditions:

  • Climate: Goldenrain trees thrive in temperate climates. They are adaptable but prefer areas with well-defined seasons.
  • Soil: Well-drained soil is essential. They can tolerate various soil types, including sandy or loamy soils.
  • Sunlight: Full sun is ideal for goldenrain trees, as it promotes optimal flowering and seed production.

Caring for Goldenrain Trees:

  • Watering: While goldenrain trees are relatively drought-tolerant once established, they benefit from regular watering, especially during dry spells.
  • Pruning: Prune to shape the tree and remove dead or diseased wood. Goldenrain trees have a naturally appealing form, and excessive pruning is generally not required.
  • Fertilization: Goldenrain trees are not heavy feeders. A balanced fertilizer applied in spring can support healthy growth. The TreeHelp Goldenrain Fertilizer is designed specifically to address the nutrient needs of the Goldenrain tree.

Common Diseases and Pests:

  • Powdery Mildew: Like many ornamental trees, goldenrain trees can be susceptible to powdery mildew, which manifests as a white powdery substance on the leaves. Fungicides, such as Liquid Copper and proper spacing for air circulation can help manage powdery mildew.
  • Scale Insects: Scale insects may infest goldenrain trees, causing yellowing and stunted growth. Horticultural oils can be used for control, as well as Monterey Once A Year Insecticidal Drench, which can be watered on the tree roots.
  • Anthracnose: This fungal disease can cause leaf spots and defoliation. Pruning and disposing of infected material can help manage anthracnose. Treat with Monterey Complete Disease Control fungicide.

Goldenrain trees are appreciated for their attractive appearance and ability to thrive in urban environments.

Promoting the Overall Health of Your Tree

To bolster a tree's defense against diseases and insect invasions, it is important the prioritize its overall health to reduce susceptibility. Enhance your tree care routine by employing the TreeHelp Annual Care Kit for Goldenrain Trees and adhering to a consistent, proper watering regimen.

Comprising three essential components, the TreeHelp Annual Care Kit focuses on ensuring the availability and effective uptake of proper nutrients. Inside, discover a custom formulated specialized fertilizer, mycorrhizal fungal treatment, and a green-up Biostimulant. The mycorrhizal treatment functions akin to bacteria in the human digestive system, breaking down nutrients and moisture into a form readily metabolized by the tree.

Recognize the significance of regular watering. Opt for less frequent, yet prolonged waterings when hydrating trees. The objective is to wet the entire root zone to a depth of 24 to 36 inches, not merely the surface. Unlike brief rains that only normally penetrate 5 to 6 inches of soil, leaving lower roots dry, a systematic watering program proves instrumental in sustaining urban trees. Embrace this comprehensive approach to fortify the vitality and overall health of your Goldenrain tree.
