Soil Additives

Question

How do I know how much wood ash or other ingredients to use in order to make my garden soil healthy enough to grow good crops? My root crops are small and few. My tomatoes and squash do fine.

You really need to do a soil test (either a home test or one from the extension service) to tell exactly what your soil might need and how much. This article can help you with knowing what your soil's needs might be:

As for your root vegetables, the soil is probably too heavy. You can amend it to make it lighter: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/how-to-improve-clay-soil.htm
