Hate it when that happens! Any more, I only buy a bit of potting soil, or an occasional trailer load of "compost", that is in a big pile I can examine before loading any.
I MIGHT make a trip to local feed lot this year, to supplement the chicken/rabbit house cleanout & local restaurant coffee grounds. After about 10 years, the dirt is finally becoming decent soil. Leaves & leaf mold are very difficult to come by; this is pine country.
Still have some leaves to fight through. Is there a good way for me to be using them?
(still kinda new to some of this)
