Dahlia question - Help needed
Can some help me, I thought I had planted all my Dahlia's but I've come across another lot, the thing is I didn't divided them last year as I have trouble finding where to divide them,
Now I can see the eyes on these ones, so can I divide them now ?
if so once I have divided them can I plant straight away if not then what do I do?
I have only been growing Dahlia's for about 3 years and have left them in the ground where they rotted, So I used pot and they still rotted in there, so I lifted them last year and they have come through ok, but need your help on dividing.
My other question is, I would like to grow my Dahlias in the ground so they get to a really good size, my soil is clay, what would you recommend I do to get my soil in to a good enough condition so I can plant my Dahlia's in to it.
Thank you for your help.
