How to Care for Cleome: Sun, Soil, Water, and Staking

Overview

Cleomes are care‑free once established—tall, sturdy stems topped with spider‑like clusters in pink, white, purple, red. Heights range from 12 in. (dwarf) to 5–6 ft (thorny). All are easy maintenance.

Step 1: Plant After Frost

Transplant or direct‑sow after all freeze danger. Cold kills tender seedlings.

Step 2: Full Sun

6+ hours daily. Shade reduces blooms and causes flopping.

Step 3: Enrich Soil

Work manure or peat into native soil. Fertile, well‑drained preferred.

Step 4: Water Consistently

Keep moist, especially in heat. Established plants tolerate drought.

Step 5: Fertilize for Blooms

Slow‑release every 6 weeks (high middle number). Or water‑soluble foliar feed every 2 weeks.

Step 6: Deadhead or Seed Save

Prune spent flowers for rebloom. For seeds, let dry on stem—heads fill with tiny black seeds.

Step 7: Stake Tall Varieties

Use stakes for 5–6 ft types. Shorter cultivars stand alone.
