HA, we will soon be going to level 5 water restrictions ... no outdoor watering period, no hoses, buckets, cans nothing!
That tree looks like it's doing OK considering it would be in compacted clay and no mulch, however when it rains you might find the water pools there a bit due to the concrete and building.
Mulch will help, they're a tough tree, good strong wood and unlike gum trees dont grow a 6" dia limb 40' long! There should be plenty of places to target cut that tree.
Many trees have died here in this drought, today I was down at New Farm park with the kids on the big Banyan is not happy with the top of the tree pretty much bare now. |
