Growth and Care Tips for Salvia leucantha (Mexican bush sage)

Right location: Salvia leucantha (Mexican Bush Sage) thrives in full sun but will tolerate partial sun. If you put it in partial sun, the plant might not grow as full and lush, and its color may become less vibrant.

Soil Preparations: The plant requires fertile, well-drained soil. You can also mix 3-4 inches of organic compost to improve the drainage and add some nutrients to the soil.

Temperature and Humidity: Mexican bush sage does best in the heat and blooms late summer into early fall. It is not hardy below 18°F.

Fertilizer: Provide this plant with a balanced fertilizer in spring when growth begins, which will promote strong development and more blooms.

Pruning: The plant may be pruned 2 to 3 times in spring and summer to make the plant bushy and promote blooming. Remove any dead or damaged stems.

Pests and Diseases: The plant is affected by some pests like whiteflies, aphids, and spider mites. So, the plant should always be checked, and a mixture of dish soap with water, neem oil, or soapy water may be sprayed to keep the plants healthy.

Take a Cutting: Select a healthy branch from the parent plant. Next, clip off a tip from the stem, 4 to 6 inches in length, using clean and sharp shears.

Potting Mix: Fill a pot with a well-draining soil. Using a pencil or stick, simply poke a hole in the bottom of the pot for drainage.

Plant the Cuttings: Place the cutting inside the pot and fill up gently around with soil.

Watering and Light: Then, place the pot in a sunny and warm place and water it normally. The soil should be kept moist but not soggy.

Transplanting: Over the next few weeks, you will begin to see new growth of Salvia leucantha. Let them grow a few inches tall, and move them into big pots before planting them in the garden.
