Everything it needs
9 essentials at a glance
Watering
Bassia scoparia prefers well-drained soil and should be watered moderately.
Water when the top inch of soil feels dry, typically every 1-2 weeks during the growing season. In winter, reduce watering to once every 3-4 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement includes south-facing gardens or patios. While it can tolerate some partial shade, too little light may result in leggy growth and reduced flowering.
Soil
Bassia scoparia prefers sandy or loamy soil with good drainage.
The ideal pH range is 6.0 to 7.5. A potting mix that includes perlite or sand can enhance drainage, preventing root rot.
Humidity
This plant is tolerant of various humidity levels but prefers moderate humidity (40-60%).
To increase humidity, mist the leaves or place a humidity tray nearby. Signs of low humidity stress include browning leaf tips and leaf drop.
Temperature
Bassia scoparia thrives in temperatures between 70-85°F (21-29°C) and can tolerate temperatures as low as 20°F (-6°C) in hardiness zones 3-10.
It prefers warm conditions but should be protected from extreme heat above 95°F (35°C).
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10, applying every 4-6 weeks during the growing season.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves, poor growth, and reduced flowering.
Pruning
Prune Bassia scoparia in late winter or early spring before new growth begins.
Use clean, sharp pruning shears to remove dead or damaged stems and to shape the plant. Deadheading spent flowers can encourage more blooms throughout the season.
Repotting
Repot Bassia scoparia every 1-2 years or when it becomes root-bound.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter, and follow these steps: remove the plant from its pot, gently loosen the roots, place it in the new pot with fresh soil, and water thoroughly.
Propagation
Propagation can be achieved through seeds or stem cuttings.
For seeds, sow them in spring after the last frost, covering lightly with soil. For stem cuttings, take 4-6 inch cuttings in late spring, dip in rooting hormone, and place in moist potting mix. Keep the cuttings in a warm, humid environment until roots develop, usually within 4-6 weeks.

Summer
During summer, ensure the plant receives full sun and water regularly, especially during hot spells. Monitor for pests and diseases.
Fall
In fall, reduce watering as the plant prepares for dormancy. You may continue to deadhead spent flowers to encourage late blooms.
Winter
In winter, minimize watering to once every 3-4 weeks and keep the plant in a cool, dry location to prevent rot.
