Planting & Care

Planting Instructions:

  1. Site Selection: Choose a location that receives part sun to full sun. In cooler climates, it can tolerate full sun, but in hotter areas, provide afternoon shade.
  2. Soil Preparation: Ensure the soil is well-draining and rich in organic matter. You can improve soil quality by mixing in well-rotted compost or other organic material.
  3. Planting Depth and Spacing: Dig a hole as deep as the root ball and two to three times as wide. Set the plant in the hole, ensuring the top of the root ball is level with the soil surface. Space plants 3'6" to 4' apart to allow for mature spread.
  4. Watering: After planting, water thoroughly to settle the soil around the roots. Maintain consistent moisture, especially during the first growing season as the plant establishes.

Care and Maintenance:

  1. Sunlight: Ensure the plant receives a minimum of four hours of sun for best flower color and stem strength.
  2. Mulching: Apply a 2-3 inch layer of shredded bark mulch around the base of the plant to help retain soil moisture and keep the roots cool.
  3. Pruning: Prune in early spring, just as new growth begins to emerge. Cut the whole plant back by about one-third of its total height. This encourages robust growth and helps develop strong stems. Avoid more severe pruning as it can deprive the plant of the opportunity to develop sturdy stems.
  4. Deadheading: Removing spent flowers is not necessary for the plant to continue blooming, but you may do so if desired. Feel free to cut stems for indoor enjoyment as it makes an excellent cut flower.
  5. Watering: Water regularly to maintain consistently moist soil, adjusting for rainfall and ensuring proper drainage to prevent waterlogged conditions.
  6. Fertilizing: Apply a slow-release fertilizer in spring, following the product instructions for application rates.


  • Wilting or Yellowing Leaves: This can be a sign of either overwatering or underwatering. Adjust your watering schedule accordingly and ensure proper soil drainage.
  • Poor Blooming: Ensure the plant is receiving enough sunlight. Too much shade can result in reduced flowering.
  • Pests and Diseases: Keep an eye out for common garden pests and treat as necessary. Smooth hydrangeas are generally resilient, but good gardening practices can help prevent issues.
