    1. Take a coffee can and remove the top and bottom of it.
    2. A hole has to be dug at a depth of 4 inches into the soil.
    3. The can have to be placed in the hole and soil has to be packed around it so that it would be safe in the ground.
    4. The coffee can have to be filled with water.
    5. After one hour, you can take a measurement of how much quantity of water has been dropped down in the coffee can.
    6. If you see that a minimum of 2 inches of water has been escaped in that one hour, then it means that the soil has a good drainage system which would be perfectly suitable for the growth of Collards.
  • The next step is to test the pH of the soil. Collard greens would be able to resist if the range of the pH of the soil is in between 6 and 7.5. You can buy a soil pH testing kit. There are two types of soil testing kits like paper strips and digital probes.

  • Make sure that you are adding a compost layer if your soil has high percentages of sand and clay. Collard greens are the one which would be able to tolerate most of the soil varieties, but the soil in which they have been planted need to have a very good amount of organic matter in them. If you find that your soil has a high amount of sand and clay, once it becomes loose, the compost has to be dumped on top until you see a layer which has a thickness of 4 inches. Make use of your spade to add some compost to the first soil layer. If you do not have any compost, you can also make use of manure in place of that.
