Q: How can I tell if my avocados are ready to pick?A: Unlike a lot of fruits, avocados won't ripen on the tree. When you think the crop is about ready, pick a couple of avocados every few days and see if they ripen at room temperature in a week or two. When some do, you can assume most of the ones on the tree are ready to pick. If picked too soon, the fruit won't ripen and will be rubbery; if left too long, the oils start to taste rancid and the flesh will be dry. Left on the kitchen counter, avocados will be ready to use when they give slightly when you press them. If you have too many ripe ones, you can toss them in the freezer and use them later for guacamole.
