Question

How do I know when peanut plants are ready for harvesting?

Answer 1

It typically takes 4-5 months for the plants to mature. Your first indication of ripe peanuts is when the leaves begin to turn yellow, at which point you'll want to dig up a few and check to see if they are ripe. If not, check periodically (every 2-4 days).  They must be harvested before a frost, which may destroy the peanuts.
