In many avocado orchards, the tips of the leaves—and in severe cases the leaf-margins also—become brown as the leaves reach full maturity. Tissue-yellowing usually precedes the leaf-burn, and the extent of leaf-burn depends on the nature of the seedling variety and concentration of chloride in the leaf tissue.
