      Why plant Audubon® Native Sourwood Treeling?

      Sourwood is a well-kept secret among tree afficianados. It does not grace a lot of homes, and that’s a shame, because it’s one fantastic tree! This elegant, slow-growing native has something to offer in every season—airy sprays of white flowers in summer, lava-red foliage in fall, and handsome, blocky bark the rest of the year. What’s more, it’s a pollinator paradise! Sourwood is not a secret among beekeepers—honey bees relish the blossoms, and from it they make what many consider to be the finest honey in the world. Native bees delight in the blooms, too.

      Native from Pennsylvania to Florida and west to Indiana, the Sourwood Tree is a wonderful part of our country’s rich natural heritage. What makes it extra-special is that it is the only species of Sourwood (Oxydendrum) in the world. Gardeners in other countries covet our beautiful Sourwoods, but most Americans don’t even know they exist! This elegant tree can be found at forest edges, in fencerows, on streambanks, and atop gravelly ridges in the Southeast. It is one of the very first trees to turn color in the fall, so you might notice it along roadsides in September when driving there—even at 55 mph.

      How to use Audubon® Native Sourwood Treeling in the landscape?

      Sourwood are perfectly sized for modern lots and the best choice for a shade or accent tree in yards.

      Audubon® Native Plants & Trees

      Audubon is devoted to protecting birds and the places they need, while Bower & Branch is devoted to the growth of true native trees and plants–no cultivars or hybrids. Together, we strive to unite communities in conservation and inspire individuals to cultivate a better world for birds starting in their own backyards, balconies, or patios. By guiding and recommending trees and plants truly native and beneficial to your region, we can really start to make a difference.

      What is the definition of Native?

      “In the United States, a native plant is defined as one that was naturally found in a particular area before European colonization. Native plants are the foundation of a region’s biodiversity, providing essential food sources and shelter for birds, especially those threatened by the changing climate. Since native plants are adapted to local precipitation and soil conditions, they generally require less upkeep, therefore helping the environment and saving you time, water, and money.” – The National Audubon Society

      How To Plant Audubon® Native Sourwood Treeling

      Sourwood is a tad fussy in the landscape, but it can be grown well when given what it needs to flourish. Sourwood is in the same family as Azaleas and Rhododendrons, and it relishes the same things that most of those plants do—acidic soil enriched with compost, regular irrigation, good drainage, and a topping of organic mulch. It also benefits from having access to a rich source of beneficial fungi in the soil. Site it in a position in full sun for the best flowering and fall color, although light shade is excellent, too. Disease and insect problems are few.

      How To Water

      Water your Sourwood consistently for the first growing season. Once established the plant can sustain itself from rainfall.

      How To Fertilize

      Let your Sourwood establish for a year before fertilizing. In the fall, after the leaves have dropped use our Elements Starter Plant Food.

      How To Prune

      A young tree may need a little extra support to ensure that it lives a long and healthy life. Stake your new Treeling with a 6-8 foot tall wood or bamboo stake. Use expandable ties that will stretch as the tree grows, fastening the stake to the main trunk from the base to the top. Check the ties every few months, at least twice a year; ensuring the ties are not digging into the trunk. If there is any sign of this, take the tie off and reattach it, giving the tree more room to grow.

      As your tree grows, remove a few of the lower branches each year in mid to late summer. Remove these lower branches before they reach 1/2 inch in diameter. It is better to make small cuts to avoid cutting a large, more mature branch - this is too stressful for the tree. Each year, make any corrective pruning needed, paying particular attention to removing damaged branches, rubbing branches, multiple leaders at the top, or suckers at the base. Limit any pruning to no more than 25% of the branching structure in a given year. Pruning benefits the tree and helps to achieve a balanced tree form.

      After two or three years you can feel free to remove the stake from the tree.

      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!

      Just happy to have a hard to find tree

      Pros: I have a hard to find tree, it seems to be in good health and producing new growth (which the deer enjoy so I have to protect it)

      Cons: Split trunk (two trunks, trying to decide if I should prune one), tops had been pruned to fit in the box.
