The Hazel Alder is an early bloomer that provides visual interest and supports animals, making it an invaluable addition to a yard. Also known as Alnus serrulata, this tree blooms in March and April. Male flowers are slim and green, and female flowers are red. Woody cones with scales replace the blooms and mature by fall. Green leaves fade into orange before dropping in the fall. Smooth, gray-brown bark provides color year-round.
Birds and deer feed on the cones throughout the winter when other food sources are scarce. Hazel Alder thrives in damp soil, making it a good pick for areas with increased moisture, like near ponds, streams, or marshy areas. This plant is native to North America, requiring little attention once acclimated. Grow the Hazel Alder in zones 4 through 9.
Hazel Alder Care
Choose a spot that receives full to partial sun and plant in rich, moist, well-drained soil. Water young trees for the first growing season, but established trees seldom need water, especially when grown in damp conditions. These trees are not heavy feeders, and fertilization is not required.
Remove dead or damaged growth as necessary. Hazel Alder trees have an excellent natural form and seldom need pruning or shaping.
Hazel Alder Spacing
The Hazel Alder reaches 10 to 20 feet tall and spreads 8 to 15 feet wide. Choose a spot away from powerlines or overhead obstructions. Space trees 10 feet apart.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
