I have been taking cuttings and planting in pots for the last couple weeks..We have had temps as low as 42-45 already this fall and that is to cold for coleus in my humble opinion. I am looking for an early frost if these cold spells continue..To be 45 the next 2 nights.....I have also started in water and have had several even die out in that.,..Have much better luck with a good sized cutting in pots.. Have quite a few already rooted and did some more potting today......And I have the vast majority of them live till spring...
