Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flower spikes to encourage further flowering.

How do I propagate Kniphofia?

Kniphofia can be propagated by division, stem cuttings, or keiki. Division is the most common method. In early spring or fall, carefully dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-drained soil.

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.
