Two weeks ago I planted 2 jacaranda saplings in 2 different areas in soil that is clayey in texture.
One area I notice tends to stay wet longer. the jacaranda in this section appears to be doing fine. The other section looks somewhat dry. The jacaranda in this section I noticed have begun to show signs of burn at the tip of the leaflets.
These saplings have been deeply watered every 5 or so days.
I'm wondering what could be causing the leaves to show sign of burn. Could the problems be lack of water, too much water or poor drainage?
If leaf tip burn is due to poor drainage, will removing the sapling and lining the bottom with a couple inches of gravel be of any value?
