Bowl of Arugula

Arugula, known for its peppery flavor and tender leaves, is an incredibly nutritious leafy green that can spice up salads, sandwiches, and even pizzas.

This fast-growing plant thrives in cooler weather, making it a perfect choice for spring and fall planting in Kentucky.

In Kentucky, I usually plant arugula in early spring, around mid-March to early April, after the last frost. A second round can be planted in late summer, typically from late July to early August, to enjoy a fresh harvest in autumn.

You can use this easy tool I have made to find your USDA hardiness zone and Typical last frost dates based on the zip code where you live:


Planting

Arugula prefers full sun but can tolerate partial shade, especially in the warmer months. It thrives in cooler temperatures, with a sweet spot between 45°F to 65°F.

Soil Preparation

For optimal growth, arugula likes rich, well-draining soil that’s packed with organic matter. A pH range of 6.0 to 7.0 is perfect for nutrient absorption.

I often enrich my soil with compost or well-rotted manure to provide plenty of nutrients. This method helps ensure healthy plants and tasty leaves!

Planting Facts

  • Best Time to Plant: Early spring and late summer
  • Zone: USDA Hardiness Zone 6a to 7a
  • Direct Sow Dates: March 15 to April 10 & August 10 to September 5
  • Soil Temperature: 45-65°F for optimal germination
  • Days to Maturity: 30 to 40 days
  • Water Needs: Moderate, about 1 inch per week

Arugula thrives in cool weather. Plant in full sun to partial shade for best results.

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.

Aerobin Compost Bin

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

Starting arugula seeds indoors is possible if you want an earlier harvest, but I find direct sowing in the garden works just as well. Sow the seeds about ÂĽ inch deep and 1 inch apart.

Once the seeds sprout, thin them to 6-12 inches apart for good air circulation and growth. Regular harvesting of the younger leaves encourages the plant to keep producing.

Arugula is a great candidate for succession planting; I like to sow a new batch every few weeks for a continuous supply of fresh greens in my kitchen!

While arugula is quick to grow and can be harvested at just a few inches tall, leaving them a bit longer can enhance their flavor profile.

Organic seed varieties suited to local conditions are usually my go-to when sourcing seeds, ensuring a robust harvest.

Growing arugula in raised beds is an excellent way to extend the growing season, and it can often yield better results due to improved soil warmth.

Watering and Feeding

Maintaining consistent moisture is crucial for arugula; it loves a well-watered soil but hates to be soggy. Regular light watering works wonders to keep the leaves tender.

I also find that using a balanced fertilizer during the warmer growth months can invigorate leaf production, making them even more delectable.

Care and Maintenance

  1. Check soil moisture regularly to prevent drought stress.
  2. Protect young plants from pests like aphids by using row covers if necessary.
  3. Harvesting regularly is key to preventing the plants from bolting.
  4. Opt for succession sowing for a steady supply of fresh greens.

Harvesting

Harvest your arugula leaves when they reach about 3-6 inches tall. Simply cut the outer leaves with scissors to allow the inner leaves to continue growing.

Arugula is fantastic raw, but don’t hesitate to toss it in a stir-fry or lightly sauté it for a unique twist.

One of my favorite ways to enjoy arugula is in a fresh salad with sliced pears, walnuts, and a tangy vinaigrette. It adds a spicy kick that makes every bite special!

With its versatility in the kitchen, arugula is a fantastic crop that ensures delicious meals and valuable nutrition from my garden.

Q&A

Can it be grown indoors?

Yes, arugula can be grown indoors. Start seeds in a container with good drainage and place it in a sunny area. Ensure proper watering to keep the soil moist.

How long does it take to grow?

Arugula is a fast-growing green and can be ready for harvest in as little as 4-6 weeks, especially when leaves are picked young.

Can you grow arugula in the summer?

While arugula prefers cooler temperatures, it can still be grown in summer if protected from extreme heat or sun, such as using partial shade or mulching to retain soil moisture.

What pests should I watch out for?

Common pests include aphids, flea beetles, and slugs. Using row covers or organic pesticides can help protect your plants.
