Tipu Tree Help Needed
I had a 24" box Tipu planted in November. It has done well so far as it has leafed out nicely and grown more than a foot since it was planted.
Two days ago it looked fine. All leaves nice and green.
Today I noticed that around 20% of the leafs had turned yellow. What do I need to do to correct that problem?
It is on 4 emitters and gets a watered for 2 hours every 2 weeks. Also on the same drip line and watering schedule is a 15 gal Hong Kong Orchid tree, and a Willow Acacia tree.
Hong Kong Orchid tree hanging in there but really haven't grown at all. Acacia tree looks fine.
Should I increase water, decrease water, other?
Thanks in advance for your help.
