The organic soil amendment should make up 25-50% of the total volume of the soil. Less than 25% will not aerate the soil properly and more than 50% may deter plant growth. Purchase organic soil amendment materials at a local garden center or hardware store.

The color change should take about 30 seconds. Use the color chart provided in the kit to find the PH level of your soil.
