Birch trees in Wisconsin offer a range of benefits, from their striking white bark to their ability to thrive in cold climates.
Their striking white bark is a key characteristic, and it's not just for show - it helps protect the tree from disease and insects.
The cold hardiness of birch trees is also a significant benefit, as they can tolerate temperatures as low as -40°F, making them a great choice for Wisconsin's chilly winters.
However, birch trees also present some challenges, including their susceptibility to bronze birch borer infestations.
These infestations can be devastating, causing the tree to decline rapidly and even leading to death.
Despite these challenges, many Wisconsin gardeners and landowners find the benefits of birch trees to be well worth the risks.

Birch Tree Basics
Paper Birch is one of Wisconsin's most iconic native trees, found in the northern and southern parts of the state.
Its prominent and phenomenal paper-like peeling bark makes it preeminent among other birches, and it's a popular landscape plant that provides pizzazz and picturesque fall color.
You can also know Paper Birch as White Birch or Canoe Birch.
Yellow Birch has the classic, showy, exfoliating bark similar to that of other birches, although with a yellow-bronze hue.
This tree can live for 150 years or more, making it a long-lived and adaptable Wisconsin native tree.
The inner bark and branches of Yellow Birch have a taste and smell reminiscent of wintergreen.
Birch Tree Care
Birch trees can be a bit finicky, especially when it comes to pests. Bronze birch borers and leaf miners are common problems for all birches, and stressed trees make easy targets.
To keep your birches healthy, it's essential to site them well and avoid wounding the tree. Thin bark on birches invites pests to take hold, so use caution when mowing or trimming around the tree.
Yellow Birch is a bit more resistant to infestations than other birches, but it's still important to keep an eye out for problems. Regular inspections can help you catch any issues before they become major problems.

Suggested Uses
Paper Birch trees are often planted in groups, but they also work well as a stand-alone landscape specimen.
Their unique bark is a major selling point, with a papery-white characteristic that develops when the trunk and branches are at least 1-1.5″ in diameter.
In areas with excessively high alkalinity, consider substituting birch for something like Bur Oak or Chinkapin Oak as an alternative, as Paper Birch can develop chlorosis on more alkaline sites.
To get the best performance out of your Paper Birch, plant it in an area with a soil pH of 6.5 or below.
Yellow Birch trees, on the other hand, can tolerate some salt exposure and are adaptable to alkaline soil, although acidic, well-draining soils are preferred.
They can grow up to 50 feet wide, so make sure to give them plenty of space to spread out.
Birch trees in general don't like compacted, clay soil and require good drainage, so plant them in a spot with plenty of moisture.

Pests/Problems
Birch trees can be susceptible to pests, especially if they're not in optimal health. Bronze Birch Borer is perhaps the Midwest's most severe pest of birch trees.
Improper siting is a common reason for encounters with the Bronze Birch Borer. Trees sited properly are often healthy and vigorous, making them less attractive to the borer.
The Bronze Birch Borer's larva spends the winter in small cells beneath the bark and transforms into pupae in spring. The adults typically emerge in Wisconsin in early June and may continue into July.
Their damage causes girdling, preventing water and nutrients from moving above the attack site. Typically, it takes 3-4 years to kill the entire tree.
Paper Birch is perhaps the most susceptible to the bronze birch borer among all our native birches. River Birch has the highest natural resistance to this insect pest.
Prevention is your best method of control. Making sure your birch is happy and healthy is the best thing you can do to protect the birch from this insect.
Birch trees are also susceptible to minor pests like aphids, birch leaf miner, and birch skeletonizer.
Birch Tree Facts
Birch trees are incredibly resilient, able to thrive in Wisconsin's cold winters and wet springs. They can tolerate temperatures as low as -40°F and survive with only 20-30 inches of annual rainfall.
Their bark is a distinctive white or silver color, peeling off in thin layers to reveal a smooth, papery surface beneath. This unique trait helps protect the tree from disease and insects.
The paper birch, a common species in Wisconsin, is particularly known for its striking white bark. It's a favorite among wildlife, providing food and shelter for various animals.
Leaf Lore
Betula papyrifera, also known as Paper Birch, has several common names, including White Birch and Canoe Birch. The specific epithet papyifera means “paper-bearing”.
Paper Birch wood is used extensively in wood products like furniture, cabinets, and general-purpose lumber. It's easily worked and takes finishes and stains readily.
Native Americans used the bark for baskets, storage containers, mats, baby carriers, moose and bird calls, torches, household utensils, and canoes. The wood was also used to make canoes, earning it the name Canoe Birch.

Yellow Birch can live to around 150 years of age, with some specimens reaching over 300 years. This is impressive, considering the average lifespan of many trees.
Yellow Birch can naturally hybridize with Paper Birch (Betula papyrifera) and Bog Birch (Betula pumila, syn. B. glandulifera). This is an interesting phenomenon that highlights the interconnectedness of tree species.
Birch trees have a sugary sap, like Sugar Maples, that can be made into a tea or tincture. The sap has a lower sugar content than maple syrup sap, but a higher yield.
The Ojibwa people used the inner bark medicinally as a diuretic, as well as to treat internal blood disease. The bark was also used for storage containers, baskets, and dishes.

We commonly grow Paper Birch in the following sizes: 2-4 feet, 4-6 feet, and 6-8 feet.
