Planting & Care

Planting and caring for the Tianshan® Seven-Son Flower (Heptacodium miconioides) is relatively straightforward, making it an excellent choice for gardeners of all experience levels. To ensure the health and success of this unique and stunning plant, follow the guidelines below:

  1. Site Selection: Choose a location that offers well-draining soil and receives full sun to partial shade. The Tianshan® Seven-Son Flower is adaptable to various light conditions but will produce more abundant blooms in sunnier locations. Make sure the area allows for the plant's mature size, which can reach 10-15 feet tall and 8-10 feet wide.
  2. Soil Preparation: The Tianshan® Seven-Son Flower prefers well-draining soil with a slightly acidic to neutral pH (6.0-7.0). Amend the soil with organic matter, such as compost or well-rotted manure, to improve its structure and fertility. This will encourage healthy root development and overall plant growth.
  3. Planting: Dig a hole twice as wide and as deep as the root ball. Gently loosen the roots and place the plant in the hole, ensuring that the top of the root ball is level with the surrounding soil. Fill in the hole with the amended soil, firming it gently around the base of the plant to remove air pockets. Water thoroughly to settle the soil and establish good root-to-soil contact.
  4. Watering: The Tianshan® Seven-Son Flower requires regular watering, particularly during its first few years as it establishes its root system. Water deeply once a week, adjusting the frequency depending on weather conditions and soil type. Avoid overwatering, as this can lead to root rot and other health issues.
  5. Mulching: Apply a 2-3 inch layer of organic mulch around the base of the plant, keeping it a few inches away from the trunk. Mulch helps to conserve soil moisture, maintain a consistent soil temperature, and suppress weed growth.
  6. Fertilizing: Apply a slow-release, balanced fertilizer in early spring, following the manufacturer's instructions for rate and application method. Avoid over-fertilizing, as this can cause excessive growth and reduce the plant's overall health.
  7. Pruning: Prune the Tianshan® Seven-Son Flower in late winter or early spring before new growth begins. Remove any dead, damaged, or diseased branches, as well as any that are crossing or rubbing against one another. Maintain the plant's natural, upright form by trimming back overly vigorous or wayward branches.
  8. Pest and Disease Control: The Tianshan® Seven-Son Flower is relatively pest and disease-resistant. However, keep an eye out for common issues, such as aphids or leaf spots, and address any problems promptly to maintain the plant's health.
