Several different varieties will be ripening and ready to harvest this month. To test if they are ready to harvest, lift the apple in the palm of your hand and give it a slight twist. If it comes away easily, it’s ready, if not it needs longer on the tree. However, cooking apples can be used before they are fully ripe. If you want to store dessert apples over winter, it’s best to pick and store them before they’re ripe, otherwise they quickly deteriorate.
