How to Plant Swedish Aspen Trees

If you are looking for an attractive deciduous tree that can provide a quick privacy screen or add interest to your landscape, the Swedish Aspen (Populus tremula 'Erecta') may be the perfect choice. These slim and upright trees have distinctive leaves with serrated edges that flutter in the slightest breeze, giving them their nickname of "quaking aspen." Here are the steps to follow when planting Swedish Aspen trees:

Step 1: Choose the Right Location

Swedish Aspen trees prefer well-drained soil and full sun exposure, but they can also tolerate partial shade. Clear the area of any grass, weeds, or debris and dig a hole that is twice as wide as the root ball of your tree. Make sure the hole is deep enough to accommodate the roots without burying the tree trunk too deeply.

Step 2: Prepare the Soil

Remove the tree from its container or burlap and loosen any tangled or circling roots. Place the tree in the hole and fill the space around the roots with a mixture of soil and compost or peat moss. Tamp the soil down gently to make sure there are no air pockets and water the tree well.

Step 3: Add Mulch

After planting, add a layer of mulch around the base of the tree to help retain moisture and suppress weeds. You can use wood chips, shredded bark, or any other organic material that will decompose slowly over time. Be sure to keep the mulch a few inches away from the trunk of the tree to prevent rotting.

Step 4: Water and Fertilize

Keep the soil around your newly planted Swedish Aspen tree consistently moist but not saturated. Water it deeply once a week, or more frequently during dry periods. In the first year, you can also fertilize the tree with a balanced fertilizer to encourage healthy growth. Apply the fertilizer in early spring before new growth appears.

Step 5: Prune and Maintain

Swedish Aspen trees require minimal pruning, but you may want to remove any suckers or weak branches that sprout from the base of the tree. You can do this with sharp pruning shears in late winter or early spring. You may also need to stake your tree if it is tall or exposed to windy conditions. Check the ties regularly to make sure they are not too tight.

In summary, planting Swedish Aspen trees is a fairly easy process that can yield great rewards. These lovely trees can provide shade, privacy, and a touch of elegance to any landscape. With the right care and maintenance, they can thrive for years to come.
