I was delighted to achieve 100% germination from my packet of Cerinthe major seeds but once potted on they have gone weak and spindly and four weeks on have yet to develop their true leaves. How can I encourage them to develop?

On plant Cerinthe major



I plant mine in situ, rather than indoors. They're fine outside, and germinate well. I'd plant them out and let them get on with it - there's not much else you can do, I'm afraid, unless you leave them and be patient a bit longer.

it is advisable to wait until the plant gets the first/2nd set of true leaves before potting on. The seedlings are having to regenerate roots before new leaves. I know it is tempting to pot on asap but patience being a virtue is true here.

If they have gotten longer, as well as weak and spindly, they may not be getting enough light in their new home, too.

How do I say thanks?
