Cilantro Growing Guide🌿: Planting, Watering, and Harvesting Tips

Introduction

Cilantro is a fast-growing, versatile herb beloved in countless cuisines worldwide. It thrives in SIPs and wicking beds, where bottom-up hydration promotes lush growth and prolongs harvests. Using GardenWells inserts keeps your cilantro perfectly watered while reducing maintenance — making it ideal for balconies, patios, and raised beds alike.

When to Plant Cilantro

  • Spring: Direct-seed in April through May once frost danger has passed. See the April Gardening Guide for early sowing strategies.

  • Summer: Choose slow-bolt varieties and succession sow every 2–3 weeks to keep a steady supply; see the June Gardening Guide for tips on maintaining SIP hydration during heat waves.

  • Fall: Sow a final crop in August for cool-season harvests. For guidance, visit the September Gardening Guide.

Square Foot Gardening Spacing

  • Spacing: 4–6 plants per sq ft (~4” apart)

  • Depth: Sow seeds ¼” deep

  • Companions: Pairs beautifully with tomatoes, peppers, and lettuce.

How to Plant Cilantro

Direct Seeding (Preferred)

  • Cilantro dislikes transplanting, so sow directly when possible.

  • Plant 2–3 seeds per hole, thinning to the healthiest seedling after germination.

  • Keep SIP soil consistently moist to encourage quick, strong sprouting.

Transplanting (Optional)

  • If starting indoors, use biodegradable pots to minimize root disturbance during transplanting.

Watering Your Cilantro

Cilantro benefits from consistent, even hydration:

  • Use your WaterStem to monitor levels: when the Hummingbird rises, the reservoir is full; when it drops, refill.

  • Before establishment: Top-water lightly for the first 7–10 days until roots reach SIP moisture zones.

  • After establishment: Refill reservoirs every 1–2 weeks, adjusting for heat and plant size.

  • Mulch lightly to maintain SIP moisture and keep roots cool during summer.

Harvesting Cilantro

  • Leaves: Start harvesting tender leaves 25–35 days after sowing.

  • Cut-and-Come-Again: Snip outer stems first and let the center regrow for ongoing production.

  • Coriander Seeds: Allow plants to bolt and dry for coriander seed harvests later in the season.

Common Issues & Fixes

Issue Likely Cause Solution
Early Bolting Hot temperatures or stress Use slow-bolt varieties and provide partial shade
Yellowing Leaves Overwatering or nutrient deficiency Use SIPs or wicking beds for controlled hydration and add compost
Poor Germination Dry soil or compacted mixes Keep SIP soils consistently moist and avoid heavy compaction

Companion Plants for Cilantro

Best companions (with cross-links):

  • Tomatoes → Cilantro’s aroma can deter tomato pests.

  • Peppers → Excellent pairing for culinary use and companion planting.

  • Lettuce → Shares similar watering needs and thrives in SIP microclimates.

  • Spinach → Cool-season partners for early SIP planting.

  • Carrots → Complementary root depths maximize SIP space.

Avoid planting with:

  • Fennel → Competes chemically and stunts cilantro growth.

  • Other strong-rooted herbs that can overshadow cilantro’s shallow SIP roots.
