To a gardener choosing which plants to grow, pH is an important consideration. While the pH of most soils falls somewhere between 3 and 9, the majority of common landscape plants prefer a pH slightly on the acidic side, say 6.2 to 6.8. However, some plants, such as blueberries and rhododendrons, prefer an even more acidic soil (with a pH in the 5 to 6 range) and other plants, green ash trees and clematis, for example, do best under more alkaline conditions, with a pH above 7.
It seems such a waste—we use a tea bag to make a lovely cup of tea, and then toss it into the trash. It just screams to be repurposed—surely there’s some way to get some extra use from that depleted bag! So it’s no big surprise that the internet is suddenly full of lists with titles such as “7 Random Uses for Used Tea Bags.”
Dirt is fascinating. Oh, I know, you’re thinking of the dirt you wash out of your clothes, or off your car. I don’t find that kind of dirt very exciting at all. But the dirt in a garden is a whole ’nother story!
Actually, dirt is just one component of what gardeners prefer to call “soil.” Rocks weather and break down into smaller rocks, pebbles, gravel, and finally sand and silt. These tiny particles mix with organic matter—decomposing plants and animals—called “humus.” Then there’s air, and water. Add in weed seeds, worms, bugs, and a huge variety of microorganisms, and you have the living stuff in which we plant our gardens.
