To test: add 2 teaspoons of garden soil to a jar and a few inches of cabbage water. Stir and wait for 30 minutes. Check the color. If it turns pink, your soil is acidic. If it is blue/green, your soil is alkaline. There are quite a few fruit and vegetable plants that thrive in acidic soil.
Do It Yourself Soil pH Test. 1. Take a soil sample from 4 - 6 inches below the surface of your garden. If you have a small garden, you can mix soil for 3 - 4 different spots. If you have a large or spread out garden, it would be better to test several samples separately.
