How to Propagate Mexican Sage
- 1). Prepare a planting container ahead of time. Any container with a drainage hole in the bottom will work. Fill the container with commercial potting mixture. Water the potting mixture, then set the container aside to drain until the potting mixture is damp but not soggy.
- 2). Cut several 3- to 5-inch stems from a healthy Mexican sage plant. Pinch the leaves from the bottom half of the stem.
- 3). Place a small amount of powdered rooting hormone on a paper plate. Dip the bottom inch of the stems in the powder, then plant the stems in the potting mixture with the leaves above the soil.
- 4). Cover the container with a plastic bag, then secure the bag with a rubber band. Place the container in indirect light. Avoid direct light from a sunny window, which can scorch the tip cuttings.
- 5). Check the potting mixture every two to three days. If the soil is dry, open the plastic bag and mist inside with a spray bottle.
- 6). Remove the plastic bag when you notice new growth, usually three to four weeks. Discard any tip cuttings that are dead or shriveling. Plant each tip cutting into its own 3- to 4-inch plastic pot filled with commercial potting soil.
- 7). Place the pots in bright sunlight. Water the Mexican sage when the soil feels dry to the touch, then allow the water to run through the drainage hole. Never allow the pot to stand in water, as Mexican sage is prone to rot and mildew in soggy soil. Allow the soil to dry slightly before watering again.
- 8). Plant the new Mexican sage plants outdoors after all danger of frost has passed in spring. If you live in a warm climate where the weather doesn't freeze in winter, the sage can be planted outdoors in autumn.
