    Has anyone noticed a difference in the ease (or lack of) rooting between different croton cultivars? Lee from Tampa sent me a big bunch of cuttings earlier in the summer. I've treated them all the same - all were dipped in rooting hormone, stuck in potting soil, put under a grow light in a terrarium - but some varieties rooted quickly, others took a while, and at least one is barely rooting. The one not rooting very readily for me is "Stoplight". One cutting of "Stoplight" seems to have died and the other is on shaky ground.

    I am up north in Delaware, growing my crotons in pots. This summer has been unusually cool and I'm sure that has affected my croton rooting speed and success rates.

    Yes. Some are fast while others will make you tear your hair out. Ram's Horn is one of the hardest to root, at least for me.

    Ron,

    I would blame the cooler weather for your cuttings not rooting at a similar pace. But, varieties do vary from one to another, that's for sure.

    Ron,

    In general, I've found the older cultivars easier to root than the newer varieties. I agree with Jeff that your temps have everything to do with the slower rooting. Please post some photos when you get a chance. It's great that you're growing these gorgeous plants up there. What do your friends and family say when they see these plants?

    Thanks for the feedback. I suspected heat was part of my problem. I could try a heating pad on "low" under my "rooting terrarium". If that fails, I might have to bug someone on this forum for a "Stoplight" cutting!

    I will post some photos of my plants shortly.

    There's plenty of Stoplight down here Ron. Let us know how it goes.

    Ron - I will start some airlayers of "Stoplight" and get a decent rootball going for you to plant next spring. We can't let you croton collection go without a Stoplight. This should give you a jump at starting it rather than a cutting. We can't allow our Northern Crotonhead to get discouraged. :p

    Ron ;)

    Ron,

    THANKS !!! I can confirm both my "Stoplight" cuttings did not root successfully. Just about everything else rooted and they didn't. So if you can grow me one and send it up with roots, that would be fantastic!

    I am going to go through my "rooting greenhouse" tomorrow and see what varieties I have now - will post something soon about that.
