2. When To Water Arugula Vegetables?

You may not know the exact amount of water to water your arugula each day as it depends on the hot weather or rain and the moisture in the soil. So you should watch for some signs of arugula to water as needed.

  • Withered leaves, drooping plants: For any plant, when there is a lack of water, there is a phenomenon of wilting and drooping leaves. Therefore, you need to quickly water more to prevent the plant from being severely dehydrated and dying.
  • Dry soil: You can test the moisture in the soil by poking the soil about half an inch with your finger. If you feel the soil is dry, water gradually because arugula have shallow roots, they will quickly absorb water from the surface.
  • During extreme weather: If you live in areas with high temperatures, you should water regularly in the morning and evening to ensure that the Arugula is getting enough water. They have shallow roots so they also quickly lose water because they can’t get water from deep within the soil.
  • Clay: Arugula is a vegetable that can thrive in all types of soil. However, they will grow best when planted in sandy or loamy soil. A soil pH between 6.0 and 7.0 is best. So, if you grow in an area with a lot of clay, you should water more often because clay soils dry out quickly and don’t hold as much water as loamy soils.
