While shopping at Costco today I spotted a large display of worm castings. I had just picked up a bag when a lady approached me and started asking me questions about them- I must have looked like an expert, lol, cause I sure didn't look like a Costco employee dressed in my barn clothes, lol (was on my way home from the horse boarding stable).
I was trying to examine the bag to see if it had air holes in it, or any information about the castings, shelf life, instructions for use, etc. I never got to finish my examination because the lady kept me talking until I had to dash to make it to a conference at my daughter's school. Will have to check it the next time I am at Costco.
But it did occur to me that it might be interesting to buy a bag and send a sample off to the lab to see how this commercial product compares to fresh, "homegrown" castings.
Has anyone here ever had their castings tested? If so, where did you send them and how much did it cost?
One good thing came of the conversation- I convinced the lady that she should buy her castings from me. I wasn't able to convince her to buy worms and make her own castings, but I will sell her some of mine. We exchanged names and phone numbers and I hope to hear from her when she gets ready to plant her garden!
