Kat, I corrected the tractor link. It should work for you now.
Mushroom mulch is exceptional. Its more expensive than others but my opinion is, well worth it.
This stuff is a tremendous soil builder, makes mic/org. do a dance. 100% organic, no chemicals, no bad side effects, just good stuff. It works on soil improvement almost immediately. It also improves structure of clay soils. Cant go wrong with this stuff at all. A wise choice.
Eucalyptus mulch, what can I say? Its still just chipped or shredded wood. It takes a long time for it to decompose to be any value to soil. It will however reduce weeds and help with moisture evaporation. I prefer it to pine or cedar. Is what you have real woody or still slightly green? There have been concerns about Euc. oil drenching into the soil causing water absorption. Bugs don't care for it.
I'm sorry Kat, I just don't like tree mulches unless it has fully decomposed. Its okay for shrubs and trees but I wouldn't use it on veggies.
I often use a commercial mulch not bagged. I buy it by the yard.Its much cheaper that way and it has other organic material in it. Most nursery's have it in their wholesale department. Its something you have to ask for because its usually not on display. Its good stuff too.
Hope this has been helpful to you.
By the way,next to talking about God, I love gardening talk as you can see. All of my info comes from experience and years of experiments and study. Been there, done it all, but there is always new things to learn.
