The essential element in well-drained soil is oxygen. When planting perennial plants that like well-drained soils in clay, the best thing to do is to create a raised bed or berm (mounded pile of soil). Mix the native clay half and half with coarse sand or crusher fines. (DON’T use fine sand; this will create concrete.)
Secondly, how do I know if my soil is well-drained?
To determine your soil drainage, dig a hole about 12 inches deep and 8 to 12 inches wide. Fill the hole with water. Allow it to drain, refill it 12 hours later, and time how long it takes for the water to drain. If the soil drains well, all the water should be gone in 2 to 3 hours.
Moreover, what is the best well draining potting soil?
Perlite is my favorite material for adding drainage and keeping the soil airy and open. A potting soil for indoor plants containing 30% perlite will have excellent drainage and aeration and help to promote healthy roots and vibrant growth from your plants.
How quickly should soil drain?
The ideal time is between 10 and 30 minutes. If it drains in less than 10 minutes, the soil is drought-prone and most suitable for plants that need dry or well-drained soil.
Will adding sand to soil improve drainage?
Sand is one of the cheapest things you can add to your garden soil that will help to break up the soil. The small particle size of the sand will get in between soil clods and break them up, increase drainage, and help to aerate the soil for good root development. Mulching can do miracles for your soil.
