Soil Scientist Designed
My name is Ashley and I am a soil scientist with a love for plants. I have been gardening and keeping plants for over ten years. Between my formal education and my love for plants I have come up with the solution for plant people. The key to any soil recipe is your personality type, overwatering & underwatering. The other keys to look at are the soil breathability and also having light or no light source. If you have a breathable pot with good lighting, combined with an underwatering personality style you will want to have a heavier soil. The opposite to this would be having a plastic pot, no light supplement and a heavy watering personality. If this is you your going to want to get an airy light mixture with plenty of wood chips, pumice and maybe even LECA.
Remember, you know your growing environment best. What I mean by this is that there is no one fits all potting soil recipe. If there are any plants on this list you want included please let me know. This is an evolving document so I will be adding to it overtime.
