Avocado tree not looking good

Generally, the main cause of drooping leaves with most plants are under watering or over watering. The former is easier to correct unless the soil becomes water repellent due to inconsistent irrigation. If that is the case dunk the whole pot in a container bigger than the pot full of water let it sit there for a few minutes until all the bubbles has evaporated. You can also correct this problem (water repellent soil) by upgrading your pot and adding fresh soil but after you have done the dunking technique. Pull it up and let the excess h2o drain away. If the problem is over watering, then a possible root rot is causing the lethargic demeanor of your avo. The browning of the leaves is also a sign of root problem. Only you can determine which case it might be. Even partial damage or ring barking to the skin won't cause the plant to wilt considerably unless the whole bark is dead.

Happy gardening :-)
