We found a wonderful place to get mushroom compost to use along with some peat moss and vermiculite to make the soil. I love this stuff and plan to compost raised beds when we put them to bed for the winter.
Michael used his geometry to figure out how much from each bag of vermiculite and peat moss we needed to mix the soil. My job was to bring the buckets of mushroom compost from the truck to the wheelbarrow where Michael would mix it all.
Thank goodness the soil is very loose so I can pull them up pretty easy. It's hard to take all of these beautiful plants to the compost pile! I have given away some plants to anyone that wanted them.
