This is great!!! I get enthusiastic about soul health so I'm thrilled to see this post. Well done.
Just wondering about why you boil the veggies for a tea. It's preferred to have microbes and bacteria so letting them rot in water with maybe manure would be better?
Thanks @riverflows A gardener friend of mine recommended me not to place the shells directly near the plants to avoid insects that will mistreat them and as I don't have compost now but there are quite a few insects roaming around my garden, I prefer to avoid them because my plants have had a hard battle with them. I have done well doing it this way.
