| It depends. Cuttings from plants native to tropical and sub-tropical regions (like houseplants) usually root at any time of year. For plants native to temperate climates (with summer and winter), there are usually better and worse times, and that will depend on the specific plants you want to root. |

| Thanks @Leftwood. I'm looking to root cuttings from coleus and creeping phlox. I'm in north-central Massachusetts. |

| Coleus will root anytime. Garden creeping phlox are best in spring (remove any flowers or flower buds) or late summer-early fall. |
