How to grow arugula in containers

Here is step by step guide on how to grow arugula in containers indoors successfully:

1. Choose the best arugula variety

The first step to growing delicious and successful arugula starts with choosing good arugula variety. Some varieties of arugula are better than other varieties in terms of taste, flavors, and yields. So, choose wisely the variety you will grow. There are plenty of them. However, the most commonly grown varieties are Italian and common arugula varieties.

Another important thing to consider before choosing a variety is adaptability. Look whether there is a variety that is well adapted to your climatic conditions. You can find this arugula variety from your local growers.

2. Choose good container with reasonable size

Arugula loves to be spaced. Do not overcrowd them as this can cause diseases such as downy mildew and bacterial leaf spot. So, find a big container that is at least 16 inches wide and 6 inches deep.

Additionally, arugula does not like warm environment. So, use a container that is made from ceramic materials or clay. Do not use containers that are coated with black materials or made from plastics, and nylon. These materials (plastics, nylon, and polyethylene bags) can absorp heat and warm up the interior of the container, which eventually damage the arugula plant. Create holes underneath if the containers do not get one. This hole can help drain excess water out of the container.

3. Fill the container with potting mixes

If you want to use garden soil, you need to sterilize the soil with heat. This sterilization helps kill weed seeds and pathogens. Then, add compost or cocco peat, coarse sand, chopped wood chips, and agricultural lime. To this end, you can add your garden soil in the container.

4. Sow arugula seeds 0.25 inch deep

After you finish setting up the potting mixes in the soil, plant the arugula seeds in the container 0.25 inch deep. Gently cover the seeds with small soil. You can plant upto 4 seeds in the container and later thin out the less vigorous ones when they germinated.

5. Moisten the soil mix and seeds

After you are done planting the arugula seeds in the pot, gently spray water to moisten the arugula seeds and potting soil. Germination only takes place in moist environment. But, while moisture is required for germination, do not overwater the seeds. Overwatering can waterlog in the container and eventually damage the seeds. So, just water enough to keep the soil mixes and arugula seeds moist.

6. Place the container in cooled and Sunny environment

Find a well-ventilated place that receives about 6 hours of direct sunlight and place the container. Arugula loves full sun but does not like warm-weather environment. So, when you observe that the environment is warmer, move the containers to shade or indoors. Leaving the container in warm-weather environment can damage your arugula seeds, seedlings, or plants.

7. Feed your arugula with 10-10-10 fertilizer

From planting to germination and during the seedling stage, you need to mix in a small amount of slow-releasing granular fertilizer such as 10-10-10 fertilizer. When they have grown into mature arugula plants, feed them with a liquid fertilizer that is rich in nitrogen. You can alternatively use compost tea.

Arugula plants love a moist environment. So, water them regularly. But, do not flood your arugula seeds or plants with water. Water only around the base of the plant.
