Starting and growing celery requires careful planning, as it has a long growing season and specific needs. Here's a step-by-step guide to ensure your celery thrives: ### **Starting Celery from Seeds** 1. **Start Indoors Early**: - Begin seeds indoors **8-10 weeks before the last frost date** if growing in cold climates. - Use a seed-starting mix in trays or small pots. - Sow seeds **¼ inch deep** and mist them with water. - Cover lightly with plastic wrap to retain moisture. 2. **Provide Ideal Germination Conditions**: - Celery seeds take **2-3 weeks to germinate**. - Keep soil temperature **65-75°F (18-24°C)**. - Use grow lights or place them in a sunny window (12-16 hours of light per day). - Keep the soil consistently moist but not soggy. 3. **Transplanting Seedlings**: - Once seedlings have **2-3 true leaves**, thin them out and transplant them into larger containers or an outdoor garden bed. - Harden off seedlings by gradually exposing them to outdoor conditions over **7-10 days** before planting outside. --- ### **Planting Celery Outdoors** 1. **Choose the Right Location**: - **Full sun** is ideal, though celery can tolerate partial shade. - Ensure well-drained, **rich, and organic soil** with **pH 6.0-6.5**. - Add compost or aged manure to enrich the soil. 2. **Spacing & Planting**: - Space plants **6-8 inches apart** in rows **12-18 inches apart**. - Plant them at the same depth as they were in seed trays. --- ### **Ensuring Celery Thrives** 1. **Keep the Soil Moist**: - Celery needs **constant moisture**—dry spells will cause it to become bitter and stringy. - Mulch around the plants to retain moisture. 2. **Feed Regularly**: - Celery is a **heavy feeder**—apply organic fertilizer (compost tea, fish emulsion, or balanced fertilizer) every **2-3 weeks**. 3. **Blanching for Tender Stalks** (Optional): - To make the stalks less bitter, **wrap them in newspaper, cardboard, or mound soil around them** about **3 weeks before harvest**. 4. **Protect from Pests & Diseases**: - Watch for aphids, slugs, and cutworms. - Use row covers or neem oil if necessary. --- ### **Harvesting Celery** - Celery is **ready in 85-120 days** after transplanting. - Harvest outer stalks as needed or cut the entire plant at the base.

Estimating the yield of celery depends on several factors, including the variety, growing conditions, and whether you harvest individual stalks or entire plants. Here’s a breakdown of how to estimate your potential yield: --- ### **1. Yield Estimation per Plant** - A **single celery plant** typically produces **1-1.5 pounds (0.45-0.7 kg)** of stalks when fully mature. - If harvesting **stalks individually**, a single plant can yield **up to 2 pounds** over time. --- ### **2. Yield Estimation per Square Foot** - Celery plants need about **1 square foot** per plant. - Expect **1-1.5 pounds of celery per square foot**. --- ### **3. Yield Estimation per Row or Acre** - **Row Spacing**: - If planting in **rows**, spacing should be **12-18 inches between rows** and **6-8 inches between plants**. - This results in **14,000-20,000 plants per acre**. - **Yield Per Acre**: - Under ideal conditions, celery farms yield **25,000-35,000 pounds per acre**. - **Average commercial yield**: ~**30,000 lbs/acre** (or 15 tons). --- ### **4. Factors That Influence Yield** - **Growing Conditions**: Proper moisture, nutrient availability, and temperature control significantly impact yield. - **Harvesting Method**: Continuous harvesting (removing outer stalks) can extend production compared to harvesting the entire plant at once. - **Variety**: Some celery types (e.g., Pascal varieties) produce larger stalks than others. - **Soil & Nutrition**: Rich organic soil with balanced fertilizers improves stalk size and weight. --- ### **5. Estimating Yield for Small-Scale or Indoor Growing** If you’re growing celery in **hydroponics or in containers** at The Fledge, yields may differ slightly: - **Hydroponic celery** may produce **slightly higher yields** than soil-grown celery due to optimized nutrients. - Expect **1.5-2 lbs per plant** under controlled conditions. - **Container-grown celery** (indoors) usually yields **0.75-1 lb per plant** depending on pot size and care. --- Would you like help setting up a **yield tracking system** or an **ROI calculation** based on your production goals?
