Bowl of Arugula

Arugula, known for its peppery flavor and high nutritional value, is a favorite among salad enthusiasts. This leafy green is not only packed with vitamins A and C but also contains calcium and iron, making it a superb addition to a healthy diet.

With a quick growth cycle, arugula allows for multiple harvests throughout the season, making it a practical option for gardeners looking to maximize their yield.

Planting

Arugula Planting Dates in Texas

  • Best Planting Time: Late September to November and February to March
  • Soil Temperature: 45°F to 65°F (ideally)
  • Planting Method: Direct sow seeds outdoors or start indoors and transplant
  • Spacing: 6 inches apart in rows
  • Days to Germination: 5 to 7 days
  • Time to Maturity: 40 days
  • Tip: For continuous harvest, sow seeds every 2 to 3 weeks.

Arugula thrives in cooler temperatures and prefers to grow in full sun, requiring at least 4-6 hours of sunlight daily. It’s ideal to plant during the cooler months to ensure a robust growth cycle.

In Texas, the best planting dates for arugula vary slightly depending on your region. Generally, spring planting begins as soon as the soil can be worked in late February to early March, with a second crop in the fall from September to early October. This timing helps to avoid the sweltering summer heat, which can lead arugula to bolt.

Soil Preparation

This leafy green flourishes in rich, well-drained soil with a pH range of 6.0 to 7.0. To achieve the best results, I mix in compost to enrich the soil, usually a blend of 50% compost and 50% native soil to provide nutrients and improve drainage. My favorite mix includes composted leaves combined with garden soil.

The Importance of Good Soil

Before starting to grow, it’s essential to assess the condition of the soil in your garden. The best soil is a blend of mineral-rich dirt and organic matter. In my garden, I compost as much as possible to enrich the soil with nutrients. I use both hot composting for food scraps and cold composting for organic garden waste.

If you don’t have the time or space to compost, you can purchase compost from garden centers or use community composting programs. Learn more about community composting here: Learn more about community composting here.

Hot Composting bin

One insulated compost bin designed for cold regions is the Exaco Aerobin 400. It holds 113 gallons and doesn’t need turning thanks to its patented “lung” system. Plus, the built-in reservoir collects compost tea, which can be used as fertilizer.

The Exaco Aerobin 400 is available for $343.79. Check the latest price on Amazon.

Where I live I get a large tax refund every year for composting may own organic waste. Due to this saving I was able to break even on the cost at only two year use. I recommend you to check with your local government if you can receive any tax refund.

How to grow

For optimal growth, sow arugula seeds directly into the garden about ½ inch deep. Plant them 1 inch apart, thinning to 6 inches once seedlings emerge for healthy growth.

A wet paper towel method can assist germination by keeping seeds moist while you prepare the garden area. After about 5-10 days, once seedlings are sturdy, you can start enjoying your fresh arugula!

Space seedlings adequately to reduce competition for nutrients. This ensures they grow strong and vibrant, ready for harvest.

Since arugula is a fast-growing annual, you can enjoy multiple harvests by cutting the leaves back to encourage new growth. Regular trimming prevents the plant from bolting and enhances leaf tenderness.

When sourcing seeds, choose organic varieties suited for your local climate. Many garden centers in Texas carry options specifically bred for warm weather.

Containers or raised beds can effectively contain arugula, enabling better control over soil conditions and drainage, especially during the wet winter months.

Indoors vs Outdoor growing

AspectIndoorsOutdoors (Texas)
Light RequirementsRequires bright, indirect light or LED grow lights for 12-14 hours a day.Full sun is ideal; partial shade may be needed during hot summers.
Temperature ControlTemperature can be controlled; ideal range is 60°F-70°F.Dependent on seasonal weather; ideal germination at 40°F-55°F.
Soil TypeWell-drained potting mix with good fertility.Well-drained, fertile garden soil, enriched with compost.
WateringRequires consistent moisture; monitor closely to prevent drying out.Needs regular watering, especially in dry conditions; avoid waterlogging.
Pest ControlFewer pest issues; however, watch for common indoor pests.Exposed to outdoor pests (aphids, caterpillars); requires monitoring and control.
Harvest TimeCan harvest as soon as 6-8 weeks after planting.Similar harvest timeframe, but timing may vary with weather conditions.
Space RequirementsLimited by available indoor space; suitable for small containers.More space available; can plant in larger garden beds.
Flavor DevelopmentFlavor may be milder due to controlled conditions.Often results in stronger flavor due to natural growing conditions.

Watering and Feeding

Arugula needs consistent moisture during its growing cycle. Ensure the soil remains moist but not soaked to avoid root rot. A balanced organic fertilizer applied during the growth phase can enhance its health.

Harvest your leaves regularly once they reach about 4 inches long, allowing for continued production and astonishing flavor.

Care and Maintenance

  1. Maintain even soil moisture without waterlogging.
  2. Protect young plants from extreme heat or frost.
  3. Monitor for pests like aphids and caterpillars, managing them promptly.
  4. Regularly harvest arugula leaves to promote fresh growth.

Harvesting

Harvest arugula when leaves are tender and young, typically within 20-30 days of planting. You can simply snip off the outer leaves with scissors, allowing the inner leaves to thrive.

This versatile green can be added to salads, smoothies, or used as a savory topping for pizzas and sandwiches. Its peppery taste can transform any dish!

A favorite recipe of mine is an arugula salad topped with cherry tomatoes, feta, and a lemon vinaigrette. It’s a refreshing side that brightens any meal.

Don’t forget, leftover arugula can easily be wilted in sautés or pasta dishes, ensuring no garden bounty goes wasted!

Common Pests and Diseases

While arugula is relatively easy to grow, it can be susceptible to certain pests and diseases. Here are some common issues to watch for:

  • Aphids: These small insects can cluster on the undersides of leaves, sucking sap and potentially transmitting diseases. Use insecticidal soap or neem oil to control infestations.
  • Caterpillars: Various caterpillars, including those from the cabbage moth, can chew through leaves. Handpicking or using row covers can help protect your plants.
  • Downy Mildew: This fungal disease appears as yellow spots on leaves and can thrive in humid conditions. Ensure good air circulation and avoid overhead watering to minimize risk.

Benefits and Challenges of Growing Arugula

Benefits (Pros)Challenges (Cons)
Fast-growing: Harvest in as little as 6 weeks.Can bolt quickly in hot weather, leading to bitter leaves.
Nutritious: High in vitamins A, C, and K.Susceptible to pests like aphids and caterpillars.
Versatile: Great in salads, sandwiches, and as a garnish.Requires consistent moisture for optimal growth.
Easy to grow in small spaces or containers.Flavor can be too strong for some palates.
