Planting Advice for Liquidambar Styraciflua Slender Silhouette trees

When planting Liquidambar trees, such as the Columnar sweet gum tree, it is important to prepare the planting area well. Pot grown liquidambar trees can be planted at any time of the year. You will need to carry out the following to prepare your planting site.

Firstly, remove all weeds and grass within a metre of your desired planting hole then dig a hole as deep as your root mass and approximately 2x as wide. We recommend digging a square hole as this encourages the roots to grow straight as opposed to around inside the hole. To help your tree establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees), especially if you have poor soil. Gently loosen the roots and place into the planting hole.

If your soil is poor, mix 50% of the original soil with 50% high quality compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems. To see how to use a tree stake and tie, watch our informational how to videos.

Aftercare Advice for Columnar Sweet Gum trees

If you’re planting in dry weather, water well and regularly for the first few months. The same goes for spring and summer planting. Make sure to keep an eye on your young tree 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 also 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. Using a glyphosate based weed killer or installing mulch matting and bark chips will aid in this. Do not simply mow the grass around the area as this will only encourage it to grow more vigorously. A point to note, if you are mowing your grass, nearby a liquidambar tree, it is best to remove any seedballs first. These can cause a problem for the lawnmower blades. If you know your area is prone to rabbits, we would advise using a rabbit guard.

Pruning Advice for Liquidambar Slender Silhouette trees

The ideal structure is for one central leader, so if you see any competing branches, remove the weakest along with any suckers.
