Cultivation
Polygala capillaris E.Mey. ex Harv. var. angolensis Oliv. is a beautiful and unique plant that needs proper care for healthy growth and development. First, choose a suitable location with well-draining, humus-rich, and fertile soil. The plant thrives in areas with full sun to partial shade and temperatures between 15-25°C. The soil pH should be slightly acidic or neutral, between 6.0-7.0.
It is advisable to propagate the plant through cuttings, as seeds may not always produce true-to-type plants. Once you have your cuttings, dip the stem ends in rooting hormone and plant them in well-watered soil. After planting, cover the cuttings with a clear plastic bag or dome to maintain high humidity and reduce moisture loss.
Watering Needs
Proper watering is key to the survival and growth of this plant. Watering should be done regularly, especially during dry seasons, but only when the top inch of soil is dry to the touch. Overwatering can lead to root rot, which can be fatal to the plant. On the other hand, underwatering can cause the plants to wilt and eventually die. It is advisable to use a watering can or a drip irrigation system to water the plant, as it allows water to seep slowly into the soil, ensuring even distribution.
Fertilization
