Step 1: Choose the Right Location

Panicle hydrangeas are sun lovers. Unlike their shade-preferring cousins, these hardy shrubs bloom best with at least 4–6 hours of direct sunlight per day. Morning sun with afternoon shade is ideal in hotter climates like ours here in Hampton Roads. Make sure your planting spot also has well-draining soil, hydrangeas don’t like to sit in water.

Pro Tip: If you're planting in heavy clay soil, amend with compost or a soil conditioner to improve drainage.

Step 2: Plant at the Right Time

The best time to plant panicle hydrangeas is actually right now, between late July to mid August and even into the fall when temperatures are milder, but the plant can establish roots before the extremes of winter.

How to Plant:

• Dig a hole twice as wide as the root ball.
• Place the plant so the top of the root ball is level with the ground.
• Backfill with native soil and soil amendments as recommended by our Green Team.
• Water thoroughly.
• Apply mulch to retain moisture and regulate soil temperature.

Step 3: Water Wisely

Panicle hydrangeas are more drought-tolerant than other types, but consistent watering is key, especially in the first year. Aim for about 1-inch of water per week, either from rain or irrigation.

Pro Tip: Mulching around the base of the plant (2–3 inches thick) helps lock in moisture and keep roots cool.

Step 4: Prune for Performance

Panicle hydrangeas bloom on new wood, meaning they produce flowers on the current season’s growth which means you can prune in late winter to early spring without worrying about cutting off future blooms. You can even deadhead and take cut flowers during the blooming season without causing any lack of blooms the next year. 

How to Prune Like a Pro:

• Cut back stems by one-third to one-half to encourage strong, full growth.
• Remove any dead or crossing branches.

For tree-form panicle hydrangeas, maintain the trunk by removing suckers at the base.

Step 5: Enjoy the Show

Summer is here, which means your panicle hydrangeas are bursting into bloom with large, elongated clusters of flowers. Many varieties start white or green, then gradually age to pink or blush tones as the season progresses into fall.
