Arugula plant originated from Southern Europe and Western Asia. The botanical name is Erica sativa and the common name is Arugula. Arugula is actually an herb and is also a leafy-green commonly grown annual as a salad green. Arugula plant is easily grown throughout the United States as a cool-season crop in outdoor gardens. Arugula plant can also be grown indoors year round for harvest as a leafy green or as micro greens.
Growing Arugula plant
Light requirements for growing Arugula
If you actually have a south-facing window that really gets full-sun exposure for a minimum of 4 hours per day, then you might be able to grow arugula plant indoors there using just only natural light. Although you will likely have a better result if you grow the Arugula plant under a fluorescent grow light fixture. This is particularly true if you intend to grow the arugula plant through winter when the days are shorter. Make sure you use a timer to keep the lights on for about ten to fourteen hours each day
Soil requirements for growing Arugula
You have to fill the tray, small pot or window box with a moisture-retentive potting mixture. Use a container that is at least four inches deep, this allows plenty of room for root development. Make sure you always use a container with holes in the bottom for drainage.
Arugula Sowing Procedure
You need to water the soil thoroughly few hours before planting so that it’s evenly moist but not soggy. Then scatter the arugula plant seeds about half inch apart on the surface of the soil, and then scatter 1/4 inch of soil over the arugula plant seeds. You need to water the soil gently after sowing, taking care not to disturb the arugula plant seeds.
Arugula Thinning Technique
Arugula plant seeds germinate very quickly, and the seedlings can emerge in less than 1 week. You can thin them when the seedlings are a few inches tall, just carefully remove some of them so that the remaining individual Arugula plants are four to six inches apart.
Fertilizer and Water Requirement
You need to keep an eye on the soil’s moisture level, and also make sure you water the Arugula plants on a regular basis so that the soil remains moist but not soggy. Water the Arugula plant carefully from above so that you don’t damage the Arugula plants, or you can set the pot in a tray filled with one inch of water so that the soil will soak up water from below. Make sure you don’t allow the pot to sit in standing water if the soil is saturated. You can begin fertilizing when the Arugula plants are four to six inches tall. You can use a balanced such as 10-10-10 liquid fertilizer diluted with water to 1½ the rate recommended on the fertilizer’s label. You can use the fertilizer-water mixture to water the Arugula plants’ soil every 2 weeks.
You can begin to harvest the Arugula plants when the Arugula plants are about six inches tall, which is about 4 to 6 weeks after the seeds are sown. You can harvest the plant’s outer leaves by cutting the plant leaves close to the base of the plant and then leaving the inner leaves to continue growing.
If you want to harvest the plants as micro greens, you have to cut them with a sharp scissors just above the level of the soil. You can harvest just after the emergence of the first set of the true leaves, and then replant the seeds immediately in other to get started with a new crop.
