#ProPlantTips for Care:
The Red Onion is easy to care for! This is a great plant to put in a beginner garden, especially if you want to start providing food for the family. Plant the Red Onion in a full sun location as this is their ideal location to be happy and grow to their fullest. Simply till or fluff your soil then plant your onions a few inches apart. Water your Onions regularly. This will ensure consistent moisture so the Onion doesn't dry out and be sure to not overwater. You can always use the Finger Test to see if the soil is dry or not. Put your finger in the soil near the Onion. If it's dry, give it a little soak for the day!
It is best to wait to harvest the large onions until their foliage browns. Once their tops wilt and turn brown, it's time to harvest your sweet, stunning onions. Locate the onions beneath the dried foliage, then gently pry them out with a spade or spading fork. You can let them sit on top of the soil in the sun for a few days to help dry the roots down before tying the tops together in bunches and hanging them to dry in your garage to hand for a while. Then store until you're ready to eat.
