When Are Red Delicious Apples Ripe?

Save

When fully ripe, “Red Delicious” apples (Malus domestica “Red Delicious”) are a luscious red, with white flesh, a crisp texture and a sweet taste. Grown commercially and in home gardens, Red Delicious apples are best eaten fresh and are not ideal for cooking. They grow well in U.S. Department of Agriculture plant hardiness zones 4 through 7. Picking Red Delicious apples at just the right time will ensure a juicy, crisp tart treat.

Timing and Hardiness Zones

  • Red Delicious apples are mature 135 to 155 days after the trees produce blossoms in the spring. This means that you can usually harvest ripe Red Delicious apples from late August to October. But local weather conditions, including the hardiness zone your growing area falls into, will affect the harvest time for your fruits. Warmer climates will have a slightly earlier harvest period, while cooler ones will have a later harvest period. Begin checking for rip apples early to mid-August to be on the safe side.

Signs of Ripeness

  • While redness is a generally a sign of ripeness, with Red Delicious apples, this cue can be misleading. This variety turns red long before they are fully ripe. Red Delicious apples will fall to the ground when they have already been ripe for several weeks. Apples that have fallen to the ground are still edible, and this is a good indicator that other apples are ready to harvest. Red Delicious apples should still feel firm when harvested -- softness is a sign of being overripe. Fully ripe Red Delicious apples will separate easily from the tree, and the flesh will be fully white, with no green tinge. To harvest properly so you do not damage the spur or fruit, grasp the apple in your hand and pull upwards on it and then outwards, giving a slight twist as you pull. Red Delicious apples will continue ripening after harvest.

Early Harvest and Storage

  • Red Delicious apples, like other apples, are storage hardy. They stay good for a long time after they have been picked, as the fruit is able to survive on starch it has saved up during the growing period. To ensure long storage times, harvest the apples with their stems. Fruit with attached stems store longer. To ensure you do not have overripe apples, and to avoid bruised fruit since dropped fruit can become damaged, harvest Red Delicious apples a little early in the season and allow them to ripen off the tree. For long-term storage, keep in a cool, well-ventilated area, roughly 32 degrees Fahrenheit in a high-humidity environment. Red Delicious apples can be stored in cool temperatures for three to four months.

Encourage Ripening

  • Apples release ethylene gas as they ripen, so they encourage other fruits and vegetables, as well as other apples, to ripen faster. To encourage ripening, store apples together in a closed paper bag at room temperature for a few days. The enclosed space will trap the ethylene gas, encouraging ripening. As apples mature, their flesh becomes softer -- a characteristic you can test by gently pressing an apple with your thumb and fingers. The more give there is, the more mature the apple.
