I've found Penstemons to be very easy to root in late fall. I typically take cuttings in November or December, treat them with Dip & Gro and set them in a mix of 75/25 perlite/peat on bottom heat in the shade in the greenhouse and water them about every other day. I do not use any other fungicides or chemicals etc. You could probably still take them now and have success - I think cool weather is the best as long as you can put them on bottom heat. Even if that isn't an option, keep them moist and they might still root eventually.

I'll definitely give their expert advice a try. Last question: would immediately after petal drop be the best time for cuttings or can one clip them earlier in the season? _______________________________________________ Alpine-l mailing list [email protected] http://mailman.science.uu.nl/mailman/listinfo/alpine-l
