I have 3 small trays loaded with tiny 1/2" tall delpinium seedlings from seed I got through Dowdeswell's in New Zealand. Right now they just have their 2 seed leaves, but the trays are shallow so I want to transplant them as early as possible. I thought I remember that delphiniums were difficult to transplant & wondered if it might be easier earlier or a little later. Any thoughts?
Many thanks for your replies.
I think I'd wait till you can see true leaves starting to appear; usually they can take handling better when they've toughened up a bit. If you are good with intricate tasks they should be fine to transplant any time.
