Pruning roses is important because it helps to reduce disease, encourages air circulation and lets more light in. This means that the plant is focusing its attention and energy on producing beautiful blooms for next season.
Topping is the indiscriminate cutting of tree branches to stubs or to lateral branches that are not large enough to assume the terminal role. Other names for topping include “heading,” “tipping,” “hat-racking,” and “rounding over.”
Be warned there are multiple unethical, criminal people attempting tree work trying to cash in on using green waste. Their flyers will appear in Perth letterboxes close to bulk rubbish/greens waste collection.
