Often in the planting Guides on a plant you just purchased it may say something like this: “Enjoys deep, well-drained soil”. How can we tell if the area we wish to plant is what the guide is asking for? Well, there is a simple test you can do. In the area you wish to plant, dig a hole about 18 to 24 inches deep. Then, fill this hole up with water.
By watching how quickly the water drains it will let you know the type drainage you have. If the water disappears in 10 minutes or less you have sandy soil with fast drainage. If it takes one hour or more, chances are you have clay soil or an impermeable layer of compacted soil beneath the surface. This indicates poor drainage. In between you will find acceptable variations
Poor Drainage causes the soil to stay cold and wet in spring when the rains fall. This delays planting and reduces seed germination. Often plants will drown due to lack of oxygen or develop shallow roots. Roots or crowns typically will rot if the ground is too wet.
