How To Plant Summer Sparkler™ Summersweet

Summer Sparkler™ Summersweet thrives best in partial sun, but it can adapt in sunnier locations. They love slightly acidic and well-draining soils, but can be highly adaptable to other soil types.

How To Water

When newly planted, water regularly to promote a healthy root system and growth!

How To Fertilize

Fertilize your Summer Sparkler™ Summersweet yearly in early spring. We recommend using our Elements Starter Plant Food to give your plant that yearly growth push.

How To Prune

It's best to leave the spent seed heads as a winter food source for birds. Cut old wood from the base in late winter to early spring, before the new growth moves in! The Summer Sparkler™ Summersweet blooms on the current season's growth, so be sure not to prune in season!

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!
