Frequently asked

Does Colorado need lime?

Usually not. Zone Forge does not manufacture a generic lime rate for an alkaline-soil region. If a current lab report shows unusually acid soil, confirm it with the lab or local Extension before applying lime.

Zone Forge follows Colorado's cited alkaline-soil guidance rather than inventing an application rate. Review the state guidance, soil-test fertilizer recommendations, and full variable-rate prescriptions. See the science →
