Thanks Becky, you're a sweetheart!
I'm sorry if I post too much but this is all new to me and I don't know why, I never loved gardening, daylilies made me fall in love!
We have some experts I think, but italians are not like you. Italians keep their knowledge tight sealed.
It happened to me years ago when I fell in love with candlemaking.
All the things I learned and almost all materials I buy are from US and thanks to the wonderful people you are. I had the luck to find a big forum like this, and as on here, members were so helpful and kind I couldn't believe it.
So
from the bottom of my heart!!!
I supposed bags would be smaller then common soil garden, good to know I can reuse it for all the other plants!
