How to keep Cerinthe Glabra.
Water
Water honeywort frequently during the growing season for the best blossom yield. Water whenever the soil feels dry 1 to 2 inches down, as a general rule. The plant will be drought tolerant once established, but flower output will diminish without enough water.
Temperature
Smooth honeywort can tolerate a wide range of temperatures, though its distribution may still be restricted by different mixes of moisture and heat. It performs best in warm summer climates with sufficient rainfall or watering. Long stretches of cloudy, rainy weather, as well as prolonged high temperatures, increase the chance of Smooth honeywort dying. In winter, providing adequate protection from cold helps the plant survive.
Fertilizer
Smooth honeywort does well with regular, light applications of fertilizer to encourage healthy leaf growth. Fertilize Smooth honeywort about once a month during the summer. Nitrogen is essential for foliage, and providing nitrogen-rich sources helps Smooth honeywort thrive.
Pruning
To maintain a healthy and visually appealing smooth honeywort, it's important to prune it strategically, ideally from early to late spring. By trimming away dead stems and removing spent flowers, you can encourage new shoots and extend the blooming period. These practices help the plant maintain a compact shape, enhance its health, and improve its visual appeal in gardens.
