Plant die-back indicates that's its time to harvest the potatoes. Fall and winter-planted early potatoes, typically planted in August or February, are usually ready for harvest in June or early summer. Allowing the plant to die back ensures the skins of the tubers harden enough so they don't scratch off easily.
How do you know when potatoes are about the harvest?
Let the potato plants and the weather tell you when to harvest them. Wait until the tops of the vines have completely died before you begin harvesting. When the vines are dead, it is a sure sign the potatoes have finished growing and are ready to be harvested.
Do you have to wait for potatoes to flower before harvesting?
ANSWER: Don't worry if your potato plants aren't producing blooms. The flowers are not needed in order for the plants to grow delicious tubers underground. Instead, the blossoms are linked to production of the small, green above-ground fruits that resemble tomatoes.
