Cotton boll compost?

Anybody use cotton boll compost for mulch?

I don't know whether anyone else has had access to this material for mulch this year (yet...), but...

...how is your experience thus far? A few weeks ago, you said you were trying cotton-boll mulch this year: https://www.helpfulgardener.com/forum/viewtopic.php?p=142226

Any observations? Maybe other gardeners in cotton-growing areas can approach those few organic cotton growers and ask about mulch possibilities. I say "organic" because cotton uses 25% of the pesticides used worldwide, according to https://eartheasy.com/wear_orgcot_clo.htm . In the absence of specific information about the pesticide(s) used by a specific grower, it would be adviseable to inquire about organic cotton wastes for use on veggie plants.

Thanks for the info on the amount of pesticides used in the production of cotton.

I like the compost very well. It seems to make a great mat around the plants that weeds can't penetrate and moisture can. It seems to keep the plants evenly damp between waterings also.

I have noticed some small mushrooms growing at times from the mulch though. Makes me wonder if it isn't a little on the fungal side of the spectrum rather than bacterial.

Considering that I don't know the actual origination of the compost, organic or not, I'll probably discontinue it's use next year unless I can get a definitive answer.

Great to hear about the weed-smothering capabilities; that should encourage other gardeners! :)

When I first filled my raised beds with "stuff" in 2008, weird little black mushroom-like growths kept coming up for weeks/months. I finally got tired of it and collected a few into a plastic bag one morning and took my "samples" to my local nursery, where I had purchased my veggie starts.

None of them recognized the growths. But one of the staff ventured an opinion: "I can't say exactly what they are, but they tell me that you have a good, rich, organic growing medium."

She said the word "organic" without any prompting from me. Maybe the mushrooms are good news! :D
