Planting Zones

Hardiness Zone: 5-8

How To Plant Rock-N-Roll™ Bigleaf Hydrangea

Big Leaf Hydrangea grow best when they get full sun for part of the day and shade the balance of the day. Up north where the summers are cooler they like full sun for up to 6 hours each day and as you move south and the summer sun is more intense the less full direct sun is desired. In zone 8 consider 2 hours of full direct sun as ideal. Your Big Leaf Hydrangea will have pink flowers in an alkaline soil and blue flowers in acid soil.

How To Water

Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water very slowly and very thoroughly. The water needs to reach to the bottom of the root ball and that takes time. Watering needs may be altered due to extreme weather conditions.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late year. Continue this for three years to get your plant well established.

How To Prune

Prune your hydrangea right after it flowers to control its size or to tidy things up. Don't prune it hard because those stems will have flower buds for next year! Your Rock-N-Roll™ Hydrangea is a reblooming variety and will follow its initial huge flowering period with more flowers through the rest of the summer and into early Fall.

How Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box! Our big trees, sizes XL and bigger, require expert delivery and care, that means our extra-large trees are shipped on Bower & Branch trucks. We are the only ones who know how to ship our big and bigger trees and plants with tender loving care. We deliver your trees and plants directly to you. Ask Bower & Branch about planting services – we'd be happy to assist in installation.

*For Big trees and Shrubs, Size XL and bigger: Review our Seasonal Shipping Timelines and Policy here.

Your trees and plants are grown across the United States at various Bower & Branch Growers. Depending on your location, your plant orders may be shipped from various locations. Please expect orders with multiple items to be delivered over a number of days as a result. Orders made up of numerous items or selections will not arrive at your home on the same day.

Shipping Delays:

From time to time, Bower & Branch Growers may determine to delay order shipment based on various factors for plant health. Weather in your region, as well as, where your plants are grown, is always considered when shipping. Extreme weather conditions may delay some or all of your order. Bower & Branch allows our Growers to make final shipping decisions based solely to benefit your trees and plants’ health and success.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
