>> too expensive to do a lawn with them.
Lawns: never has so much money been spent, and so much water, labor and fertilizer wasted, on something so useless.
But not everyone agrees.
I think that most of the criticisms I've heard leveled against "chemical" fertilizer are addressed or mitigated by simply applying them lightly, i.e. not wastefully. A light addition of soluble fertilizer is very rapidly taken up by soil microbes and lawn roots.
Only excessive fertilizer is wasted or burns or discourages MR (mycorrhizae, but I have to look that spelling up every time).
My theory is that many Doctor Earth products can be made more effective and less expensive by just shredding $1 bills and mulching with those before applying the REALLY expensive Dr. Earth products.
Or save even more by replacing the $1 bills with old shredded cardboard or newspaper..
And replace most of the Dr. Earth bag with composted manure and the rest with a tiny amount of "chemical" fertilizer chosen to supply the specific deficiencies that YOUR bed has.
