The 'burnweed' genus prefers loose, well-drained, fertile soil and full sun to partial shade. Water regularly, ensuring consistent moisture. To plant, prepare the site by clearing weeds and debris, and enrich the soil with organic matter. Place plants in holes at a depth they grew in their containers, space them 1 to 3 feet apart. Water thoroughly after planting. Throughout the growth phase, mulch the area to maintain soil moisture. Remember, different 'burnweed' species might have individual preferences, and adjusting your care accordingly will lead to greater success.
