--answer--Feed the Soil Life properly to end up with Top Quality garden plants--
Hi refreshed,
Your question: I feel silly asking this question but what kind of green mulch are you talking about. Cut grass, pulled weeds...that sort of thing. I think of mulch as something that sits on top and not worked into the soil. I was thinking you said to work the green (like weeds) into the soil.
Two different things?
Answer: Green Mulch is like leaves or grass that is not a plant that has dried completely down or Matured out by going to seed !
Or like Hay may be considered Green vs Straw would be considered dried down?
The Hay will have much more Food Value to feed Soil Life than Straw !
Look at Cows and Horses, what do they like to eat Best?
They would much prefer to eat Green growing Grass !
Next they like Hay over dried straw !
The Green Manure is when we work Green weeds into the Soil surface to feed the Soil Life !
Green Mulch is also easier for the Soil Life to eat and break down, than Dried Matured plants that have gone to seed !
After a plant has gone to seed most of it's nutrients have left the leaves and gone into the Seeds !
Soil Life likes to eat plant parts that still contain good stuff to eat !
Just like we like to eat the best tasting parts of the plant, which are the parts having the most Natural Sugars and Alkaline Minerals !
Cause and Effect !
Smile Tis your choice.
