How to Plant, Grow, and Harvest Arugula

growing arugula

Arugula, scientifically known as Eruca vesicaria, is a leafy green plant often used in salads and other culinary applications across a multitude of cultures. Originally hailing from the Mediterranean region, it's now grown and used globally, adding a peppery flavor and a vibrant green touch to our dishes.

Arugula, also known as rocket or rucola, comes in various types, but the most popular are 'wild rocket' and 'salad rocket'. Wild rocket is smaller and has a more intense flavor, while salad rocket is larger with a milder flavor.

Besides being a flavorful addition to meals, arugula also offers an abundance of health benefits. It is rich in vitamins A, C, and K, and it provides a good source of calcium, potassium, and folate. Moreover, it is known for its high antioxidant content, which can support overall health.

Growing arugula in your own garden can be a fulfilling venture. Not only will you have a fresh supply of this nutritious leafy green, but you'll also enjoy its lush, green foliage, which can enhance the beauty of your garden and even serve as a lovely border plant.

In the upcoming sections, we'll explore how you can plant, grow, and harvest arugula in your own garden, ensuring that you're never without this flavorful leafy green when you're whipping up culinary delights in the kitchen.

Optimal growing conditions for arugula - Climate, sunlight, and soil requirements Optimal

Creating the right growing environment is crucial for the successful cultivation of arugula. This section will outline the optimal conditions that encourage the growth of this flavorful leafy green, including climate, sunlight, and soil requirements.


Arugula is a cool-season crop and thrives in moderate climates. It can tolerate a light frost, making it suitable for early spring and fall plantings. During the hot summer months, arugula can bolt, or flower, quickly. This makes the leaves more bitter, so consistent harvesting and possible successive plantings may be needed to ensure a steady supply.


Arugula enjoys full sun but can tolerate partial shade. If you're growing arugula in a warmer climate, providing some afternoon shade can help protect the plant from the intense heat, which can cause bolting.

Soil Requirements

Arugula prefers well-draining soil rich in organic matter. The ideal soil pH for arugula is slightly acidic to neutral, ranging from 6.0 to 7.0. You can improve your soil's fertility and structure by adding compost or well-rotted manure before planting. This will provide the necessary nutrients for the plant and improve water retention in sandy soils or drainage in clay soils.

When to Plant – Best time of the year for planting Arugula

Timing your planting correctly is key to maximizing your arugula harvest. This section will help you determine the best times of the year to plant arugula in your garden.

Early Spring Planting

Arugula is a cool-season crop, so your first opportunity to plant is as soon as the soil can be worked in the early spring. In many areas, this is often a few weeks before the last spring frost. Arugula seeds can germinate in soils as cool as 40 degrees Fahrenheit, and young plants can tolerate a light frost.

Fall Planting

Another optimal time to plant arugula is in the late summer or early fall. Planting arugula about 4-6 weeks before the first expected fall frost allows the crop to mature in cooler weather, which enhances the flavor of the leaves.

Succession Planting

To have a continuous supply of fresh arugula, consider succession planting. Sow a new batch of seeds every 2-3 weeks throughout the planting season. This will ensure that as older plants mature and are harvested, younger ones are ready to take their place.

Remember, while arugula is quite hardy and adaptable, it does best in cooler temperatures. Very hot weather can cause the plant to bolt and the leaves to become more bitter.

Seed Selection – Choosing the right seeds for your garden

Choosing the right seeds is a crucial first step in growing arugula. This section will guide you on how to select the best seeds for your garden to ensure a successful and bountiful harvest.

Watering – How often and how much to water the plants

Proper watering is crucial to the health and productivity of your arugula plants. This section will guide you on the frequency and amount of water needed to keep your arugula hydrated and thriving.

Frequency of Watering

Arugula prefers consistently moist soil, but it's important not to overwater. Overwatering can lead to soggy soil and increase the risk of root diseases.

In general, watering your arugula once or twice a week should be sufficient. However, this can vary based on the weather conditions and the type of soil in your garden. Sandy soils drain more quickly than clay soils and may require more frequent watering.

During hotter weather or periods of drought, you may need to water more often to keep the soil moist.

Amount of Water

When watering, aim to wet the soil to a depth of about 6 inches. This encourages the arugula's roots to grow deeper, making the plant more resilient during dry periods.

Watering Tips

Here are a few tips to water your arugula effectively:

1. Water Early in the Day: Watering in the morning reduces water loss due to evaporation and helps the plant prepare for the heat of the day.

2. Avoid Wetting the Leaves: If possible, water at the base of the plant to avoid wetting the leaves, which can lead to the growth of fungal diseases.

3. Check Soil Moisture: Before watering, check the soil moisture by sticking your finger about an inch into the soil. If the soil feels dry at that depth, it's time to water.

By following these watering guidelines, you can ensure that your arugula plants receive the right amount of water and stay healthy and productive.

Fertilizing – The type of fertilizer needed and how to apply it

Providing your arugula plants with the right nutrients can help them grow stronger and more productive. This section will discuss the type of fertilizer that's best for arugula and how to apply it effectively.

Type of Fertilizer

Arugula prefers a rich, well-fertilized soil. An organic fertilizer high in nitrogen is a great choice as it promotes leafy growth, which is what you want with arugula. Compost or well-rotted manure can also provide a slow-release source of nutrients.

If you're using a granular or liquid fertilizer, look for one with a balanced N-P-K ratio, such as 10-10-10 or 14-14-14. N-P-K stands for Nitrogen, Phosphorus, and Potassium, which are the primary nutrients needed by plants.

When to Fertilize

It's a good idea to add compost or well-rotted manure to the soil before planting. If you're using a granular or liquid fertilizer, apply it when the arugula plants are about 2-3 weeks old, and then every 4-6 weeks after that.

How to Apply Fertilizer

To apply the fertilizer, follow these steps:

1. Determine the Amount: Check the instructions on your fertilizer package to determine the correct amount to use.

2. Prepare the Fertilizer: If you're using a granular fertilizer, you may need to mix it with water. Liquid fertilizers are typically ready to use.

3. Apply the Fertilizer: Pour or sprinkle the fertilizer around the base of the arugula plants, avoiding the leaves.

4. Water In: After applying the fertilizer, water your arugula to help the nutrients soak into the soil.

Remember, while fertilizing is beneficial, too much can harm your plants. It's always better to under-fertilize than to over-fertilize.

Disease and Pest Control – Common diseases and pests that can affect arugula, and how to manage them

While arugula is generally easy to grow, it can sometimes be affected by diseases and pests. This section will outline some common problems you might encounter and provide tips on how to manage them.
