Q.Leaf loss during drought
We are experiencing a drought and the leaves on my hybrid willow trees (austree) are turning brown and falling off. Are they going dormant for the year? What about watering them?
Keep them watered as best you can. The heat and the lack of natures own water has many trees, shrubs and such dropping their leaves more than normal. All we can do is to try and keep the root zones somewhat moist and then when some cooler weather moves in and hopefully some rain, they should be okay.
