  • There are a lot of ways in which you can provide water to your green onions. Some of these methods include furrow irrigation, drip tape, and overhead watering. While drip tape irrigation is something that is largely preferred by many people, furrow and overhead watering has its own set of advantages. A large part of choosing the methods depends on where you live, how many green onions are you growing, and how much water is available with you. 
  • One should never water green onions according to a fixed schedule. One thing, it never works and second, it leads to the plants getting destroyed untimely. Watering green onions should be a rare phenomenon.
  • Nonetheless, it should be very thoroughly done. This is because it helps the plants store water for longer periods of time, thus saving you from committing the crime of underwatering green onions. 
  • To avoid extreme watering conditions, consider applying moisture to about 1 inch of your soil. This way, you always stay on a safer side while saving yourself from loads of energy and time. 
  • If you face difficulty in telling when the right time to water is, use the finger test or knuckle rule to know when to water your green onion plant. Insert your finger in about 1 inch depth of soil. If your finger comes out dry, it indicates that your plant needs water. On the contrary, if the soil feels sticky on your finger on your knuckle, keep the water away from your plant for another week. 
  • Depending on the rainfall that your area receives, you should water your plant by upto 1 inch of soil once or twice a week. Remember that the intensity of rainfall that your area receives plays a major role. To measure the level of water that the soil of your plant has, install a measuring device and get a better idea. 
  • Watering your plant frequently (more than twice a week) can lead to issues like root rot and overwatering. 
  • If you do not want to conduct a finger or knuckle test to check the water levels of your soil, you can instead have a look at the colour of the bed of your green onion soil. If it is darker than usual, it means that your soil bed has ample water and doesn’t require more. However, if there are any visible cracks with an orchid colour, install a drip irrigation system and start moisturizing the base of your soil. 
  • To avoid leaching of your green onion yields, it is suggested to use a furrow irrigation system as it allows your plant to soak up all the moisture and water made available in a steady and thorough manner. It also helps you identify early signs of disease, so you can terminate the furrow irrigation method at an earlier stage and avoid the destruction. 
  • If you are growing your green onions plants indoors, you can conveniently change your water schedule by a week or two, since indoor plants require less water than outdoor plants for many unstated reasons.

  • Green onions do not complain much when it comes to providing ample sunlight.

The soil temperature on the other hand is considered to be the best when it is around 45 degrees Fahrenheit. Germination periods demand warmer and more humid temperatures. 
  • Go for a fertilizer with a balanced NPK ratio. Preferably, the one with a 20-20-20 ratio of nitrogen, phosphorus and potassium respectively. If you have trouble finding an evenly balanced fertilizer, the one with high nitrogen levels would also do wonders. 
  • Know when the growth of green onions has reached its plateau and set a goal for why you are growing it.
