Keep Forage Calendar free
Hi, I'm Nick. I built Forage Calendar on my own and I keep it free, with no ads. If it has helped you find something good this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Peak and shoulder ratings are rough guidance, not a schedule. Microclimate, elevation, and the year's weather can shift any species by weeks.
