Impatiens balsamina, commonly known as garden balsam or touch-me-not, is an annual plant in the family Balsaminaceae. It is native to India and Myanmar but has been widely cultivated in tropical and subtropical regions. The plant is known for its bright, colorful flowers and its ability to thrive in seasonally dry tropical climates.
Garden balsam prefers bright, indirect light and moderate temperatures. It thrives in humid environments but can tolerate average household humidity levels. Water the plant when the top inch of soil feels dry, and ensure it is not waterlogged. Regularly check for pests and remove any dead or yellowing leaves to encourage healthy growth.
土壌
Impatiens balsamina prefers well-draining loamy soil that retains some moisture but does not become waterlogged. A mix of garden soil with compost or organic matter works well. Ensure the soil pH is slightly acidic to neutral for optimal growth.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and vibrant flowers. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
植え替え
Repot garden balsam annually or when the plant outgrows its container. Choose a pot that is one size larger and has good drainage. Gently remove the plant from its current pot, loosen the roots, and place it in the new pot with fresh soil. Water thoroughly after repotting.
伝搬
Impatiens balsamina can be propagated from seeds or cuttings. Sow seeds indoors 6-8 weeks before the last frost date or directly in the garden after the danger of frost has passed. For cuttings, take a healthy stem cutting, remove the lower leaves, and place it in water or moist soil until roots develop.
剪定
Prune garden balsam regularly to maintain its shape and encourage bushier growth. Remove any dead or yellowing leaves and spent flowers to promote new blooms. Pinch back the tips of the stems to encourage branching and a fuller plant.
毒性
Impatiens balsamina is generally non-toxic to pets and humans. However, it is always a good practice to keep plants out of reach of small children and pets to prevent any accidental ingestion.
