Good idea?

Kalari Drive, City Beach (click to enlarge)
"Hydrozoning" has become a widely accepted practice in Perth but I'm not sure about the wisdom of it when this happens.

This mature street tree in Kalari Drive, City Beach has died because the irrigation to the playing field verge has been turned off.

Out of frame are many more even larger street trees which are also now under threat.



If saving some water leads to this you have to question the value of it. Melbourne is flat-out trying to save it's mature trees from drought and we're deliberately subjecting ours to it (!)

  1. theres more to it than turning off the perimeters.
    I'm also about water conservation, but its horses for courses and needs a planned approach.Perhaps the perimeter irrigation can be maintained in a reduced capacity for mature and newly planted trees;and reduced or switched off in grassed areas. What works in Armadale may not work so well in deep City Beach sand.

    1. Agree - "a planned approach" is definitely the way to go. I've emailed the school and offered to assist. There's a LOT of big Eucs on its verges and it would be a disaster to see them all go off for lack of a little planning.

  2. Hi Grayden,
    there are many people that share your passion for trees, good on you. I would ask the question , is that what killed the tree as there are green trees beyond there on the hydrozoned perimeter. These perimeter trees should be drought tolerant native species in my view and weaned off the water as such. Iconic trees should still have supplementary watering if required.

    1. Thanks for the feedback. The photo is a bit deceptive. The green trees in the background are in fact on a bank of the oval that's still getting water - ie not on the dry verge.
