Limelight Hydrangea Tree is a dependable standby that provides the largest flowerheads and the best bright white and lime coloring. This grafted tree form of Hydrangea paniculata is brilliant for adding not only color to the garden but also height and textural contrast with the coarse leaves and loose flowerheads. The tree form of Limelight reaches a maximum height of 6 feet and is perfect for small yards or planting directly under utility lines.

Limelight Hydrangea Tree Care

Hydrangeas appreciate moist soil that has good drainage and a moderate amount of nutrition. Limelight will not change color based on the pH of the soil. The flowers take on the same shades of green, white, and rosy pink from year to year. Plant this standard tree in a location with direct sun early in the day and filtered or dappled shade during the hottest part of the day.  

Deadheading is rarely necessary for Limelight to keep its compact growth habit. The branches of this Hydrangea are quite sturdy and able to keep the large flowerheads fully upright. Prune the canopy lightly in the early spring to remove any damaged material from the winter. 

Fertilizing can be done once a year in the spring with a slow-release, granular formula. Select a product with a balanced 10-10-10 NPK ratio. Mulching with organic compost each spring is another great way to provide nutrients for Limelight while gradually improving the soil quality. 

Limelight Hydrangea Tree Spacing

Hydrangeas trees are easy to incorporate into existing garden schemes. Limelight will have between 3-4 feet of open trunk at the bottom, allowing perennial and other low-growing shrubs to grow quite close. Space each plant 6-8 feet apart when planting multiple Limelight Hydrangea Trees. When planting Limelight in a container, select a pot with a diameter around 18-24 inches.
