How to Tell Which Soil You Have by the Weeds
Oftentimes, improving the soil can eliminate or deter various types of weeds from returning. Understanding weeds as indicators of soil conditions will help you improve your lawn. The battle with weeds will most likely never be won. Garden soil conditions and weeds go hand in hand, so why not take advantage of the clues given for soil types and use the weeds to identify potential problems. Large populations of weed growth can signal poor soil conditions as well as soil type. Since these lawn weeds indicate soil conditions, it can make it easier to detect and fix problem areas before they get out of control.
Soil Types and Weeds
Using weeds as indicators of soil conditions can be helpful when fixing problem areas in the landscape. While there are numerous types of weeds, as well as a number of soil types and conditions, only the most common garden soil conditions and weeds will be mentioned here. Poor soil can include anything from moist, poorly drained soil to dry, sandy soil. It may also include heavy clay soil and hard compacted soil. Even fertile soils have their share of weeds. Some weeds will even take up residence just about anywhere, such as dandelions, making it more difficult to determine soil conditions without closer examination. Let’s look at some of the most common weeds as indicators of soil conditions:
