Balsam, also known as Impatiens balsamina, is an annual flower that is easy to grow and adds vibrant color to gardens and landscapes. Here are some tips for growing balsam:
-
Soil preparation: Balsam plants prefer well-draining soil with a pH level between 6.0 and 7.0. Prepare the soil by adding organic matter such as compost or well-rotted manure to improve soil fertility and drainage.
-
Planting: Balsam seeds can be started indoors in late winter or early spring and transplanted outdoors after the last frost. Plant the seedlings about 12 to 18 inches apart in rows that are spaced 18 to 24 inches apart.
-
Watering: Balsam plants require regular watering, especially during hot, dry weather. Water the plants deeply once a week, or more often if the soil is dry. Avoid getting the leaves wet to prevent fungal diseases.
-
Fertilizing: Balsam plants require a balanced fertilizer to promote growth and flowering. Apply a slow-release fertilizer or a liquid fertilizer every 2 to 3 weeks during the growing season.
-
Pest and disease management: Balsam plants can be susceptible to pests such as aphids, spider mites, and whiteflies. To manage these pests, use insecticidal soap or neem oil. To prevent fungal diseases, avoid overhead watering and maintain good air circulation around the plants.
-
Deadheading: Balsam plants will continue to produce flowers throughout the growing season if you remove the spent blooms regularly. Deadheading encourages the plants to produce more flowers.
-
Propagation: Balsam plants can be propagated by collecting the seeds from the mature plants and sowing them in the spring. Alternatively, you can take stem cuttings from the plants in the summer and root them in moist soil.
By following these growing tips, you can ensure that your balsam plants thrive and produce an abundance of colorful flowers throughout the growing season.
