I just literally got 'little lime' hydrengia's this year. We had an additon made to our landscaping and those were the first ones i bought. I have never grown hydrengia's, kinda scared. But thought i'd give it a try. So far so good though :)
"Deer and rabbits deposited manure into my gardens and lawn. Still to pull last of veggies and put away to compost. What would happen if I just left it in garden to decompose over winter, pea plants I mean?"
