Sue, I will get compost and a peat-free soil as soon as I can. As soon as the weather permits!
No leonardite then, I don't need another hit and miss thing.
Greg, I never liked peat, I started gardening in 2014. Before I had only some plants in pots, no one survived and trying to get something out of that soil was impossible, at least this is how I always felt. It simply seems something dead in my hand.
It maybe a coincidence or not: I have one DL (always afternoon) that doesn't grow and doesn't bloom, it's in the only little spot of the garden where there was no soil so I used some common garden soil with the usual truck load of peat in it. All the other DLs are living in the original clay soil I found already in the garden. I didn't see many blooms but they all grow and put up new fans. The only one that is exactly as it was when I bought (it was small I have to admit) it's that in peat.
