Preparing the Garden Bed
Location
Arugula thrives best in well-drained soil with plenty of sunlight. Aim for a location that receives at least 6-8 hours of sun each day. However, arugula can tolerate partial shade, especially in hotter climates.
Soil Requirements
-
Soil Composition: The ideal soil for growing arugula should be rich in organic matter. A mixture of loamy soil with well-rotted compost will improve soil structure and fertility.
-
pH Level: Arugula prefers a slightly acidic to neutral pH (around 6.0-7.0). Testing the soil pH can help you amend it accordingly.
-
Nutrient Needs: Before planting, incorporate a balanced organic fertilizer into the soil to provide the necessary nutrients for optimal growth.
Tilling and Preparing
-
Tilling: Turn the soil to a depth of at least 12 inches to break up any compacted layers.
-
Leveling: Rake the soil to create a smooth surface, making it easy to sow seeds evenly.
-
Moisture: Ensure the soil is adequately moist, but not soggy, before planting.
Sowing Arugula Seeds
Timing
- Spring Planting: Start sowing seeds outdoors after the last frost date in your area.
- Fall Planting: For a continuous supply of greens, sow seeds again in late summer for a fall harvest.
Direct Sowing
- Seed Spacing: Sow seeds about 1/4 inch deep and spaced 1 inch apart in rows that are 12-18 inches apart.
- Thinning: Once seedlings have emerged and are about 2-3 inches tall, thin them to 6 inches apart to allow for proper air circulation and growth.
Container Gardening
If space is limited, arugula can also be grown in containers. Use a pot that is at least 8 inches deep and filled with quality potting soil. Ensure drainage holes are present to avoid waterlogging.
Caring for Your Arugula
Watering
Keep the soil evenly moist but not waterlogged. Water regularly, especially during dry spells, to promote tender leaf growth. A drip irrigation system or soaker hose can be beneficial.
Weeding
Regularly check for weeds, as they compete for nutrients, water, and light. Hand-pulling is effective, especially if done while the weeds are young.
Fertilizing
Apply a balanced organic fertilizer every 4-6 weeks during the growing season to replenish nutrients.
Pest Control
Arugula is vulnerable to pests like aphids, cabbage loopers, and flea beetles. Implement the following measures to protect your plants:
-
Handpicking: Remove larger pests by hand.
-
Neem Oil: A natural solution, neem oil can deter pests without harming beneficial insects.
-
Companion Planting: Interplanting with strong-smelling herbs like basil can help repel pests.
Disease Management
Arugula can be susceptible to diseases like downy mildew and powdery mildew. To minimize risks:
-
Air Circulation: Ensure proper spacing between plants for good airflow.
-
Avoid Overhead Watering: Water at the base of the plants to keep leaves dry.
Harvesting Arugula
When to Harvest
Arugula can be harvested at any stage, from baby leaves to fully mature plants.
-
Baby Leaves: Pick baby leaves at around 25 days after sowing for a tender salad addition.
-
Mature Leaves: Allow plants to grow for about 40-60 days for larger, fuller leaves.
How to Harvest
Use scissors to snip the outer leaves first when harvesting, leaving the inner leaves to continue growing. Always harvest in the morning when leaves are crisp and full of moisture.
Multiple Harvests
Arugula is a cut-and-come-again crop, meaning you can potentially harvest multiple times from a single plant if you cut above the base rather than pulling the whole plant.
Storing Arugula
Short-term Storage
Freshly harvested arugula can be stored in the refrigerator:
-
Washing: Gently rinse leaves to remove dirt.
-
Drying: Pat them dry with a towel or use a salad spinner to remove excess moisture.
-
Storage: Place leaves in a breathable container lined with paper towels to absorb humidity.
Freezing
For long-term storage, arugula can be frozen:
-
Blanching: Briefly blanch leaves in boiling water for 2-3 minutes, then plunge them into ice water.
-
Drying: Drain and dry the leaves before packing them in airtight freezer bags.
-
Labeling: Label bags with the date to track freshness.
