Olive tree leaves are brown and dry

Question

I recently bought an olive tree sapling and repotted it into larger pot. I watered it pretty consistently… maybe every other day and placed it in a full sun location. Then the leaves started browning, curling and drying out. I increased the watering to almost every day according to the soil wetness (I checked to see if the soil would clump when balled into a fist or if it would fall apart-I would only water if it crumbled) and moved it to a shadier location. However, nothing could save the tree. It gradually got browner and drier until eventually every leaf was brown and crispy. Now it has just stayed like that for many weeks, however it has started spouting green shoots from the base. Is the tree dead? Will the leaves eventually revive and return? What did I do wrong?

Answer 1

I wonder if it could have Olive Xylella disease. It is a bacterium that prevents water and nutrient uptake in the tree, leaving it scorched looking. Here is more:
