When Are Crabapples Ready to Pick?
The most efficacious way to see if a crab apple is ripe is to slice it open; if the seed is brown, then the fruit is ripe. Since some crab apples turn red upon ripening, while others turn a yellowish-orange, looking inside is the best way to determine ripeness..
Crab apples usually ripen in the fall, but foragers can begin looking for consumable fruit as early as August. Over 1,000 species of crab apple tree are extant in the United States, and each of these species reaches peak ripeness at a different time between the months of August and October.
