You're aware of autumn in sun and shadows, shorter days and drier air, and so is your garden. Smart plant parents are attuned to wind, rain and frost. And they're vigilant. Succulents recovering from summer heat and sun are especially vulnerable to pests.
These seasonal succulent must-do's are for southern and coastal CA, from the Bay Area south. If you live beyond, please visit my site's Succulent Care By Season and Region page.
Aeoniums are emerging from summer dormancy. Cut back leggy aeoniums, replant rosettes, and discard old plants roots and all. See how in my video: How to Refresh an Overgrown Succulent Garden (4:48).
Trim Senecio mandraliscae by several inches, and plant cuttings in gaps. Old stems branch where cut, which helps mass plantings grow fuller. See how in my video, How to Fill Gaps in Your Succulent Garden (2:21).
Check your garden's run-off. Create channels that divert rain from succulents in low spots. If they sit where water collects, they may rot.
Fertilize in-ground succulents with Ironite. Ideal for newly planted gardens, it boosts spring growth. Take care it doesn't stain hardscape.
Check for ants in outdoor potted succulents, especially haworthias, gasterias and aloes. One tell-tale sign is soil in the crowns, pushed up from below. What to do.
Heat, sun and Santa Ana winds can desiccate succulents. Hose-water vulnerable plants. Cuttings are most at risk because they lack roots, so plant them after the winds die down.
