My best Zucchini harvest ever! (How to know when to pick)

When can I harvest zucchini? The most important factor in determining when to harvest zucchini is how long it's been in the garden. If you're harvesting an early or late variety of zuke, it'll be ripe when the plant consistently stops producing flowers and starts to die back. Otherwise, pick a zuke when its skin is tender and the stem snaps with a sharp crack.
