Steps to Grow Cilantro Choose the right variety: Opt for Calypso Cilantro, which is bolt-resistant for more leaf harvest. Time to plant: Plant in early spring after the last frost or in fall when temperatures are 50-80°F. Prepare the soil: Use loose, fast-draining soil with an acidic pH to prevent waterlogging. Plant the seeds: Sow seeds at a depth of 1/4 inch; splitting seeds can improve germination. Provide the right conditions: Cilantro thrives in full sun or partial shade. Light shade in war
