Answer: Arugula requires the soil to be fertile and rich when seeds are sown, and your arugula plants will also need fertilization as they grow. Because arugulas are a “cut and come again” crop, they need plenty of fertilizer to help them keep producing new leaves for the next harvest.

What does arugula need to flourish?
Arugula is a cool-season annual, meaning that it is good in spring or fall. Plant in full sun and fertile, well-drained soil. Like any herb or vegetable that needs to grow green leaves, arugula will benefit from compost and/or fertilizer. Water when the soil gets dry.
How often does arugula need to be watered?
Like many vegetables, arugula needs regular watering for healthy growth and optimal flavor. It has a shallow root system. Keep the soil consistently moist but not soggy, watering as soon as the top inch of soil feels dry. In dry climates, this might mean watering every morning.
Does arugula like acidic soil?
Arugula does best in nutrient-rich, well-drained soil, but will tolerate a wide variety of conditions, making it a great choice for containers, raised beds, or traditional garden beds. It prefers slightly acidic soil with a pH between 6 and 7.
How often should you fertilize arugula?
About every two weeks
Arugula plants do best when they receive fertilizer and the soil is amended with organic material before they are planted. About every two weeks once arugula plants have their first true leaves, gardeners should apply a balanced water-soluble or granular fertilizer.
Does arugula like coffee grounds?
So what I do is take the leaves and the coffee grounds (and other plant residues I can get my hands on) and spread everything over my growing plot. This mixture breaks down through the winter and releases nutrients into the soil by the time spring starts. Arugula loves such richly enhanced soil and thrives in it!
What can you not plant near arugula?
Most plants in the nightshade or solanum family are incompatible with arugula plants. This is because nightshades prefer a more acidic soil pH of 5.5-6.5 while arugula prefers a more neutral soil pH of 6.5-7. It is not recommended to grow arugula next to eggplant, peppers, potatoes, or tomato.
How do you cut arugula so it keeps growing?
Use your hands, a pair of scissors or a serrated knife and cut the stems of the leaves about an inch from the crown or the leaf base. You can simply take a few leaves off each plant and leave the rest to continue growing for the next harvest.
Does arugula come back every year?
Standard garden arugula is an annual which won’t grow back the next year, but it can easily reseed itself, sprouting new arugula plants the following year. Wild arugula (Diplotaxis tenuifolia) is a perennial which can survive moderate frosts and grow back every year.
What causes arugula to bolt?
If you wait too long, it will bolt. Especially if you’ve planted a summer crop, as this plant favors cooler weather, it will bolt much more quickly under the hot sun than it might if you planted at another time of year.
Can you grow arugula in full sun?
Season: Cool season. Arugula tends to bolt in hot weather. Exposure: Full sun to partial shade.
What fertilizer is best for arugula?
Feed arugula plants every two weeks with a balanced water soluble or granular fertilizer, such as a 10-10-10 or a 5-5-5, diluted to half strength. Look for a fertilizer in which the three numbers separated by hyphens are equal or almost equal.
What grows well next to arugula?
Plant arugula with these companions: Bush beans. Beets. Carrots.
Can arugula grow close together?
Because arugula plants are relatively small and have compact root systems, you can plant them close together, or even in a pot. As leafy greens they have less need for full sun and will even grow in partial shade or where tall plants create shade.
How fast does arugula grow?
Arugula leaves are ready to harvest 35-50 days after planting from seed. Begin harvesting arugula once the leaves are 4 to 6 inches long. The flowers of bolting arugula are edible and add a distinctive peppery flavor to dishes. Arugula flowers develop into seed pods.
Does arugula need to be thinned?
Growing Tips
Don’t forget to thin plants as they are growing to avoid overcrowding and reduce risk of disease. Pick leaves in the evening to avoid wilting in the hot sun. Arugula is a great companion plant!
How far apart should arugula be planted?
Wild arugula has a sprawling habit and feathery, deeply indented leaves. Space plants 10-15cm (4-6″) apart in rows 30cm (12″) apart. Remember that this perennial plant will re-emerge in spring. Keeping the plants cut will encourage new, more tender growth.
How do I keep bugs from eating my arugula?
Planting trap crops, such as radishes, can deter pests away from your arugula. On the flipside, you can sow plants like yarrow and marigold to attract beneficial insects, such as predatory wasps and ladybugs to help control populations on unwanted insects.
When should I prune arugula?
For a mellow, spicy flavor and a tender green, harvest when the leaves are young — about three to four inches. If you prefer a stronger flavor and a thicker, crunchier stem, allow them to grow to five to six inches and cut the entire stem at its base. Arugula will grow back once cut, so don’t pull the stems.
Does arugula need nitrogen?
You see, arugula (as well as all other leafy green vegetables such as lettuce, lamb’s lettuce, chard, spinach and others) needs nitrogen-containing nutrients to grow. These help them perform photosynthesis and grow big, green leaves rapidly.
