Q.Eucalyptus Trees shedding too much?
I have 3 trees here in California that I prune every 3 years. They are shedding a ridiculous amount of leaves in May and I still have 1 more year to go before the next pruning. The leaves are all red and we have had problems with the lerp psyllid in the past. Wondering if the massive leaf drop is just a normal seasonal thing or it’s excessive because of the lerps.
Older leaves can be shed and as they age often turn red in color.
Stress can also lead to leaf drop; environmental or disease and pests.
If you have had past issues with pests make sure you are checking your trees regularly.
These links will help you pinpoint the issue.
