Climbing yams work as a bountiful, low-maintenance staple crop for those who cultivate them. A rampant grower, climbing yam climbs all summer, and in the winter, it dies back. If not harvested, it’ll just create more tubers to harvest next season. If you do harvest it, you’ll always miss some tubers, so it’ll just grow back. No need to plant it anew. That’s huge food production in a perennial form. For more low-maintenance gardening tips and highly productive crops, follow our bio links. #permac
