How to grow & propagate genovese basil

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 genovese basil

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 genovese basil in Texas

Give it full sun and rich soil. Match the spot to the plant and most of the battle is already won.

Time your planting to our long warm season and watch the frost dates at both ends; the live weather tool on this site is built for exactly that.

In a container it'll dry faster than in the ground, so check the top inch of soil daily in summer; pots on a hot Texas patio can need water every single day.

Harvesting

Figure on roughly 60 before you're harvesting. Pick herbs in the morning after the dew dries for the strongest oils, and harvest little and often — regular cutting keeps a herb bushy and stops it bolting. The part you're after: leaves.

Making more for free

Save it the easy way — vegetatively. Because you can clone this plant from a cutting, division, or piece of root, you never have to buy it again: keep one healthy mother plant and make all the copies you want.

🌤 Before you plant: check the live 7-day garden weather to time it right for frost and heat.
