When to Pick Kohlrabi
It's easy to let things sit in the garden until they are past maturity and not as delicious. They look great out there, the fruits are just getting bigger, and harvesting is a chore. But, letting your vegetables get over mature doesn't do you any favors in the kitchen. Gardeners often put off harvesting Kohlrabi until its flavor has declined. Younger stems are sweeter and softer than older stems.
