Q.Acorn Squash
Since your web site provided the help I needed this is more of a comment than question. For the second time we have had volunteer acorn squash growing out of/next to our compost yielding several free squash. I have been told that seeds from commercially grown squash can not be relied upon to produce the same quality squash as the original. Is this correct? Our experience gives us one more reason to compost.
Hybrid varieties, often the seed is sterile or doesn’t reproduce true to the parent plant
