Tree & Woody Weed Control in Your Garden

To kill unwanted and actively growing trees, cut the tree close to the ground and using a sprayer or clean paintbrush, soak the cut surface with a diluted solution of Yates Zero Weedkiller Super Concentrate (see product label for dilution rate).

Yates Tree & Blackberry Killer is an effective way of controlling unwanted woody weeds, tree seedlings and suckers. The active ingredient, triclopyr, is systemic and travels through the plant's system, killing it roots and all.

Summer is an ideal time to get problem trees and shrubs under control, while plants are in active growth.

Yates Tree & Blackberry Killer controls Sweet Briar, African Boxthorn, Olive and Privet; and woody weeds including Eucalyptus (except Dawson gum) and Wattle seedlings and suckers, Australian Blackthorn, Camphor Laurel, Castor Oil Plant, Chinese Apple, Groundsel Bush, Lantana, Tea Tree, Tree of Heaven, and Rubber Vine.

Basal Bark Spraying

For treatment of seedlings up to 5 cm diameter (up to 10 cm for Camphor Laurel, Groundsel Bushes and Privet). Spray or paint bark and stems from ground to 30 cm height. Old rough bark may require more thorough spraying than young smooth bark. Drilling 2 cm holes or axe wounding trees helps penetration.

Cut Stump Treatment

For treatment of suckers and seedlings more than 5cm in basal diameter. Cut stems or trunks to within 15cm of the ground. Apply liberally by spraying or painting on to freshly cut surfaces. Do not treat Australian Blackthorn during the dormant period.

Some plants have invasive roots, while others are only invasive in specific situations where there is limited space and/or water.

There are clumping, and running Bamboo varieties. Clumping Bamboo grows close to the point of origin and slowly spreads over time, whereas running Bamboo spreads quickly in a horizontal direction.

Tiger Grass is not a Bamboo, but will give the same look - these are clumping plants that only grow 2-3 m and are ideal for all gardens large and small.

Fig trees, Liquiambars, and London Plane Trees can be invasive as their roots are very strong, fast-growing and quickly seek out water. These trees are best suited for large gardens where there is plenty of space to grow.

Trees that grow new plants from their roots are called suckering trees. Examples include Jacaranda, Camphor Laurel, Robinias, Gleditsia, and Poplars which can be a nuisance when you want to keep a tree contained.
