WillC said:Yes, it is probably normal as long as it is not excessive. Potted Avocados will lose some of their older leaves as they continue to add new ones on top. Although the discolored lower leaves may look and feel dry that does not mean the plant is lacking moisture. Daily watering is probably too much. Allow the top half-inch of soil to dry before watering thoroughly enough to see some water trickle through the drain holes.
WillC said:Yes, always water thoroughly after the top half-inch of soil has dried. That would probably be closer to weekly than daily.
Avocadoes normally grow a single, unbranched stem unless they are pruned or pinched. If yours is already too tall, then cut the stem back to your preferred height. Once it is at the preferred height, then use your fingertips to pinch out new top growth as it emerges. Be persistent in your pinching to encourage branching.
