Soil Testing & Science

Testing Urban Gardens for Heavy Metals

My first vegetable garden was a confidence builder in exactly one way: it taught me fast that “good dirt” is not a given. In older neighborhoods and busy suburbs, the soil can also come with baggage, especially lead from old paint and historic vehicle emissions, plus other metals and chemicals left...

Soil Percolation Test for Garden Drainage

If you have ever stood in your garden after a rain and wondered why one bed dries out in a day while another stays squishy for a week, you are not imagining things. Soil drains at different speeds depending on texture, compaction, organic matter, and even what happened on the site years ago. A...

Test and Adjust Soil pH for Better Nutrients

That season taught me something I still repeat to anyone who will listen: the garden is only as good as the...

Home Soil Test Kits vs. Lab Testing: Which Is Most Accurate?

Twelve years ago I tried to grow tomatoes in a yard that was basically brick-hard clay. I threw compost at it, watered like crazy, and still got sad, stubby plants. The day I finally tested my soil was the day gardening started making sense. But here’s the thing: not all soil tests are created...

The Mason Jar Soil Test

If you have ever stood in the garden holding a sad little plant and wondered, is it me or is it the dirt? you are my kind of person. When I started gardening in heavy clay, I blamed the sun, the seedlings, the variety, the weather, the moon. Eventually I learned the truth: soil texture runs the...
