Quality starts from the roots

by editor

With arborist inspections becoming the norm for tree supply throughout Australia and ever-increasing scrutiny on quality and root ball structures, improving growing methods was the logical next step for Tall Trees.

Growing trees that meet and surpass the recently revised AS2303:2018 Tree stock for landscape use was Tall Trees project.

Since 2015, Tall Trees have been seeing more councils and more street tree projects inspecting stock before supply or install. Often trees are rejected and rightly so for even the slightest amount of root girdling. Tall Trees made the decision to gradually move all of their street trees in production over to Rocket®pot Air Root Pruning (ARP) pots.

The design of Rocket®Pot’s guides the roots through pits in the pot’s inner wall, out through holes, in the side and base for air root pruning. This allows trees to grow and you can be confident will pass all council or arborist inspections.

To ensure Tall Trees are growing the best quality trees possible, they track their best practice method back to the initial seed germination. Their propagation stock is direct seeded into an S1020 which is a small ARP pot ensuring a healthy tap root.

From there, for each potting-on stage the root balls are inspected, and any suspect roots are manually pruned. Then they are potted into the relevant sized ARP pot. So, at no stage during development are the trees grown in a rigid wall pot. This greatly mitigates the risk of root girdling, and improves the quality of the tree ready for installation into the ground. Paired with correct and careful installation practices, this growing method should ensure a quality tree with a healthy root structure well into its maturity.

With increased market competition and ever thinning margins, the last thing your project needs is for trees requiring to be replaced after installation, or throughout a maintenance period, putting pressure on budgets. Tall Trees now grows all of its street trees using this method.

Tall Trees service the entire East Coast, and South Australia.
