Q.Jacaranda Branches Dying
The branches are starting to die on my jacaranda tree. The branches with leaves are a lighter shade of green than that of my other jacaranda trees. The tree in the photo get watered most frequently (once every two days) with sprinkler system. Is this a watering problem or something else? PS. Just after it started budding we had a heatwave and eveything turned brown that was green.

Yes, the overwatering is likely causing disease. These should only need water during drought, or periods of dry weather.
