Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate mexican bush sage
Almost everything in the mint family roots from cuttings so readily it feels like cheating. Snip a 4–5 inch non-flowering tip, strip the bottom leaves, and either set it in a glass of water on the windowsill or push it straight into damp potting mix. You'll usually see roots in 1–2 weeks. Seed works too, but cuttings give you an exact copy of the parent — which matters when one plant tastes better than its neighbor.
Beginner's path: take more cuttings than you think you need. They're free, they cost you nothing but a few minutes, and the ones that take more than make up for the ones that don't. This is how a single plant becomes a hedge, a row, or a gift for every neighbor on the street.
Growing mexican bush sage in Texas
Give it full sun and well-drained soil. Match the spot to the plant and most of the battle is already won.
Because it's a perennial, the work is mostly up front. Get it sited and established and it comes back on its own year after year — one of the best returns on effort in the whole garden.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly established before you're harvesting.
Making more for free
If you want more, let your healthiest plants mature fully and collect the seed once it's dry on the plant — then store it somewhere cool, dark, and dry until next season.
