❓ Frequently Asked Questions — Comparing These Plants

Polyscias

What are the light requirements for Polyscias?

Polyscias thrives in bright, indirect light. Avoid direct sunlight, especially during the hottest parts of the day, as it can scorch the leaves. An east-facing window is often ideal, providing gentle morning sun. If placing it near a south- or west-facing window, use sheer curtains to filter the light. Insufficient light can lead to leggy growth and leaf drop.

How do I care for Polyscias?

Polyscias requires bright, indirect light to thrive. Direct sunlight can scorch its delicate leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain humidity levels between 40-60%. Use a well-draining potting mix formulated for indoor plants. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.

How do I propagate Polyscias?

Polyscias can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag to increase humidity. Roots should develop in a few weeks.

Tithonia

What are the light requirements for Tithonia?

Tithonia plants thrive in full sun, needing at least 6 to 8 hours of direct sunlight each day. Insufficient light can lead to leggy growth, reduced blooming, and pale foliage. When growing Tithonia indoors, place it near a south-facing window where it can receive maximum sunlight. If natural light is inadequate, supplement with grow lights to ensure proper development and abundant flowering.

How do I care for Tithonia?

Tithonia requires full sun, at least 6-8 hours daily, for optimal blooming. Plant in well-draining soil, amending with compost for added nutrients. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize every 4-6 weeks during the growing season with a balanced fertilizer, or one higher in phosphorus to promote flowering.

How do I propagate Tithonia?

Tithonia can be propagated from seeds or stem cuttings. For stem cuttings, take 4-6 inch cuttings from healthy stems in the spring or early summer.
