The idea soil for most plants is loam (a mixture of sand, silt and clay). This type of soil is ideal because it allows the water to drain freely while still retaining nutrients and moisture.
Also know, what do you mix with soil to improve drainage?
Adding lots of organic matter such as compost, farm manure, or shredded leaves to clayey soil will allow it to drain more easily and hold the right amounts of water and air for better plant growth and increased biological activity. Adding sand can be tricky and typically is not recommended to be added to clay soil.
Additionally, how do you make well drained soil? 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.)
