Planting Arugula

1. Choosing the Right Time to Plant

Arugula is a cool-weather crop, and it grows best in early spring and fall. It can tolerate some heat, but it is crucial to avoid planting it during the hot summer months. You can also plant it indoors using hydroponics systems, which will provide a controlled environment for the plant to grow. 

2. Choosing the Right Location

Arugula loves full sun, but it can also grow in partial shade. Make sure to choose a location with well-draining soil and a shallow root system. The soil should also be rich in nutrients and have a pH level between 6.0 and 7.0.

3. Planting Arugula Seeds

To plant arugula, you can either use seeds or seedlings. If you are using seeds, follow these steps:

  • Prepare the soil by tilling it to loosen it and remove any debris.
  • Sow the seeds about an inch apart in rows that are about six inches apart.
  • Cover the seeds with soil to a depth of about 1/4 to 1/2 inch.
  • Water the seeds gently to avoid washing them away.

4. Germinating Arugula Seeds

Arugula seeds usually germinate within seven to ten days. During this time, it is essential to keep the soil moist, but not waterlogged. You can cover the soil with a thin layer of mulch to help retain moisture and keep the seeds warm.

Caring for Arugula Plants

1. Watering

Arugula needs regular watering, especially during hot weather. It is important to avoid overwatering the plants, as this can lead to root rot. Water the plants deeply once a week, or more often if the soil is dry.

2. Fertilizing

Arugula plants do not require a lot of fertilizer. However, you can add a nitrogen-rich fertilizer, such as fish emulsion or blood meal, to the soil before planting the seeds. You can also use a balanced fertilizer every four to six weeks during the growing season.

3. Harvesting Arugula

Arugula is ready to harvest when the leaves are about three to four inches long. You can harvest the outer leaves, leaving the younger leaves to continue growing. This will ensure a continuous harvest throughout the growing season.

4. Storing Arugula

Arugula has a short shelf life and should be used within a few days of harvesting. You can store it in the refrigerator in a plastic bag with a paper towel to absorb moisture.

Tips for Growing Arugula

  • Plant arugula in early spring or fall for the best results.
  • Arugula seeds should be sown about an inch apart in rows that are about six inches apart.
  • The seeds usually germinate within seven to ten days.

How to Grow Arugula

Common Issues and Solutions

While arugula is generally easy to grow, there are a few common issues that you may encounter. Here are some solutions to these problems:

1. Bolting

Bolting is when the plant sends up a tall flower stalk, which can cause the leaves to become bitter and tough. To prevent bolting, make sure to plant arugula in a cool, shady area and keep the soil moist.

2. Pests

Arugula is relatively pest-resistant, but you may encounter aphids, flea beetles, or slugs. You can control these pests by using insecticidal soap, neem oil, or diatomaceous earth.

3. Disease

Arugula can be susceptible to fungal diseases, such as damping-off or downy mildew. To prevent these diseases, make sure to plant arugula in well-draining soil and avoid overwatering.

Conclusion

Growing arugula is a great way to enjoy fresh and tender leaves of salad greens with a peppery flavor. With its shallow root system and heat-tolerant nature, arugula is an easy plant to grow and care for. By following the steps outlined above, you can successfully grow arugula and enjoy a continuous harvest throughout the growing season.

Remember that arugula is a cool-weather crop, and it grows best in early spring and fall. If you live in an area with hot summers, consider planting arugula indoors using hydroponics systems. This will provide a controlled environment for the plant to grow and thrive.

In summary, arugula is a member of the mustard family and a leafy green vegetable with a peppery flavor. It is easy to grow and care for, making it an excellent addition to any garden.
