What can neutralize the lime water?
Sweet scented osmanthus tree like acid, not love salt, water is diluted, and little effect, with vinegar, then there will be soluble salt, or will inhibit growth?. The best use of baking soda water, and then use a lot of water to wash roots, salt and alkali can be removed, and do not worry, then add some vinegar, but certainly not much oh. Hope your tree will soon recover!
Lime is alkaline, so it should be neutralized by acidic substances, taking into account the plant, so the choice of weak acid substances is best!
Sprinkle some vinegar into the soil. It contains acetic acid, pH, and watered down, because the leaves have fallen off a lot and are already very serious. Dilution is useless
