How to Grow Arugula in Singapore: A Step-by-Step Guide

Before diving into the details, let’s begin with a brief introduction to arugula. Arugula is a cool-season vegetable that thrives in moderate temperatures, making it well-suited for Singapore’s tropical climate.

This leafy green belongs to the Brassicaceae family and is a close relative of kale, broccoli, and cabbage. Growing arugula at home not only provides you with a fresh and sustainable food source but also allows you to enjoy its unique flavor in various dishes.

Selecting Arugula Seeds

Choosing the right arugula seeds is crucial for a successful growing experience. Look for high-quality seeds from reputable suppliers or nurseries. Opt for varieties that are well-suited to Singapore’s climate, such as “Astro,” “Sylvetta,” or “Slow Bolt.”

These varieties are known for their heat tolerance and resistance to bolting, which is when the plant prematurely produces flowers and seeds. Consider organic seeds whenever possible to ensure a chemical-free growing process.

Preparing the Soil

Arugula thrives in well-draining soil that is rich in organic matter. Prepare the soil by removing any weeds, rocks, or debris and loosen it to a depth of around 8 to 10 inches. Incorporate compost or well-rotted manure to improve soil fertility and moisture retention.

Arugula prefers slightly acidic soil with a pH level between 6.0 and 6.8. Test the soil pH and make necessary adjustments using organic soil amendments if needed.

Planting Arugula

Arugula can be directly sown in the garden or started indoors and transplanted later. If sowing directly, make shallow furrows in the prepared soil, approximately ¼ inch deep. Space the furrows about 12 inches apart to allow sufficient room for the plants to grow.

Sow the arugula seeds thinly along the furrows and cover them lightly with soil. If starting indoors, use seed trays or pots filled with seed-starting mix. Sow the seeds according to the package instructions, usually about ¼ inch deep, and keep them in a warm and well-lit area until the seedlings emerge.

Watering and Fertilizing

Consistent and adequate watering is essential for the healthy growth of arugula. Keep the soil evenly moist but not waterlogged. Water the plants deeply whenever the top inch of soil feels dry. Mulching the soil around the plants can help retain moisture and suppress weed growth.

Avoid overhead watering to minimize the risk of fungal diseases. Arugula is a light feeder, and excessive fertilization can result in lush foliage but reduced flavor. Use a balanced organic fertilizer sparingly or incorporate compost into the soil before planting.

Managing Pests and Diseases

Arugula is relatively resistant to pests and diseases, but certain issues may still arise. Common pests that may affect arugula include aphids, flea beetles, and snails. Monitor your plants regularly and take appropriate measures if you notice any pest activity.

Use organic pest control methods like neem oil, insecticidal soap, or companion planting with repellent plants. Ensure good airflow around the plants to prevent the development of fungal diseases. If necessary, apply organic fungicides as a preventive measure.

Harvesting Arugula

Arugula leaves can be harvested when they reach a desirable size, usually around 3 to 4 inches long. You can either harvest the outer leaves individually or cut the whole plant about 1 inch above the soil surface.

Regular harvesting promotes continuous growth and prevents the plants from bolting. Freshly harvested arugula leaves can be stored in the refrigerator for up to a week. For longer storage, blanch and freeze the leaves or consider preserving them by making pesto or drying.

Storing and Using Arugula

To store arugula, wash the leaves thoroughly and gently dry them using a salad spinner or paper towels. Place the dry leaves in a resealable plastic bag or an airtight container lined with a paper towel to absorb excess moisture.

Store the bag or container in the refrigerator’s vegetable drawer, where the temperature is cooler. Properly stored arugula can stay fresh for up to a week. Remember to rinse the leaves again before using them in salads, sandwiches, stir-fries, or as a flavorful addition to pasta dishes.

Common Arugula Varieties

Arugula comes in various varieties, each with its unique characteristics. Some popular arugula cultivars include “Astro,” which has smooth, dark green leaves and a mild flavor, and “Sylvetta,” also known as wild arugula, which has deeply lobed leaves and a strong, peppery taste.

Another variety to consider is “Slow Bolt,” which is specifically bred to resist bolting and can be harvested over a longer period. Experiment with different varieties to find the ones that best suit your taste preferences and growing conditions.

Benefits of Growing Arugula

Growing arugula offers numerous benefits beyond the pleasure of harvesting and enjoying your own fresh greens. Arugula is a nutrient-dense vegetable, rich in vitamins A, C, and K, as well as folate, calcium, and antioxidants.

How long does it take for arugula to grow from seed to harvest?

Arugula typically takes around 30 to 40 days from seed to harvest, depending on the variety and growing conditions. You can start harvesting the leaves when they reach a suitable size for your taste preferences.

Can I grow arugula year-round in Singapore?

Arugula is a cool-season crop and grows best in moderate temperatures. While it can tolerate some heat, it may bolt or become bitter in hot weather. Aim to grow arugula during the cooler months in Singapore, such as from November to February.

How often should I fertilize arugula plants?

Arugula is a light feeder and doesn’t require heavy fertilization. Incorporating compost into the soil before planting should provide sufficient nutrients. If needed, you can apply a balanced organic fertilizer once or twice during the growing season, following the package instructions.

Can I save arugula seeds for future planting?

Yes, you can save arugula seeds for future planting. Allow some plants to bolt and produce flowers. Once the flowers dry up, harvest the seed pods and store them in a cool, dry place. When you’re ready to plant, simply remove the seeds from the pods and sow them according to the instructions.
