When?

Plant in spring or early fall so roots settle before summer heat or winter cold. Divisions and cuttings root easily through the growing season.

Step by step

1. Pick the sunniest spot you have; shade makes stems weak and floppy.
2. Plant in gritty, fast-draining soil or a raised bed; add grit to heavy clay.
3. Water after planting, then let the soil dry out between waterings.
4. Feed sparingly if at all; rich soil leads to soft, sprawling growth.
5. Pinch tall types back in late spring for sturdier, bushier plants.
6. Propagate from stem or leaf cuttings; fallen leaves often root by themselves.
