Standard:

Plant 20 to 25 feet apart

Grow 12 to 15 feet tall

Harvest:
To determine if the fruit is ready for picking, cup fruit in your hand and give it a gentle twist; if it pulls away easily leaving the stalk behind it is ripe. A ripe apricot will be slightly soft and sweet tasting. Let apricots ripen on the tree as long as possible.
