Alnus incana 'Laciniata' Tree

Alnus incana 'Laciniata' is a beautiful, graceful tree with finely cut foliage that is grey-green in colour, turning yellow in autumn. The catkins and cones are popular with wildlife and the almost oriental form of this cut-leaved Alder tree makes it a great choice for ornamental gardens.

Well suited to wet sites, Alnus incana Laciniata is a popular choice for difficult positions as it is also tolerant of most soil types and exposed positions. Laciniata is a medium sized, conical Alder tree that is slightly more compact  than our native Common Alder and grows to approximately  6 x 4 meters in 20 years.

Planting Alnus incana Laciniata Trees

Our pot grown Cut Leaved Alder trees can be planted at any time of the year, unlike bare root trees. They cope in a range of conditions, including wet sites. Start by removing weeds and grass within a metre of your intended planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, especially if you have poor soil, we advise sprinkling root grow in the hole.

Take the pot off and gently loosen the tree roots, then place into the planting hole. Mix 50% of the original soil with 50% compost, then fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree. We advise planting young trees with a stake and tie kit and, if your area is prone to rabbits, a rabbit guard. Lastly, water around the base.

Aftercare Advice for Alnus incana Laciniata Trees

If you’re planting in spring, summer or dry weather, water well and regularly for the first few months. Make sure to keep an eye on young Cut Leaved Alder trees and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We stock a range of irrigation kits, suitable for a variety of planting schemes.

Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons.

Pruning Advice for Alnus incana Laciniata Trees

Like most ornamental trees, Cut Leaved Alder trees do not require much pruning once they have established. Simply remove any crossing, damaged or diseased branches. Prune in late winter or early spring. If you think the canopy is overcrowded, make sure to alleviate the branches to ensure enough air and light can penetrate. Alder trees produce their own nitrogen so they do not require fertiliser, only a consistently moist soil.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. *Pot sizes may vary. Below are definitions of terms:

Supplied Size: Height measured from the top of the pot.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Clump: Several plants in one pot that can give the appearance of a multi stemmed and very bushy tree.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branches of the crown). Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height:
