Use a mixture of 20% to 50% Genesis Biochar and compost and/or other amendment(s). For trees planted with the burlap bag and ball of roots make your hole twice as large as the ball and fill it with the mix. It is best to give the biochar time to absorb and stabilize with the amendments for as long as is practical but at a minimum of three days. keep the mix wet before mixing it into the soil. If your planting soil has already been amended you can mix your Genesis Biochar directly into the soil at 5% to 10% ratio. Water it well each day for a few days. You will find a variety of purchasing options in our store.
