What’s The Best Fertilizer For Onions?
If you want to know, how to grow onions bigger, then having knowledge about plant foods will be beneficial. These include the best fertilizer and nutrients that will keep them thriving. Onions grow best in soil that is well drained with a pH of 6.0 to 7.0. The growing medium should also be high in organic matter for your plant to get sufficient nutrients.
Conducting a soil test will help determine if the area you choose to grow them is suitable for planting. Also, a combination of compost and manure is recommended to enhance their size. This is because both are rich in nitrogen, phosphorus, and potassium which are key elements that feed the plant’s root system.
You can also topdress the soil with a sprinkle of fertilizer at least three months before planting. Make sure you choose onions that are adapted to your area since they come in short and long-day varieties. As soon as the tops die down, you can use a composted manure-based fertilizer at one pound per 100 square feet. You’ll also want to add an all-purpose granular fertilizer at the rate of 1-2 pounds per 100 square feet.
Is Epsom Salt Good For Onions?
Yes, Epsom salt is good for onions and this is another key factor in enhancing their growth. This salt is a compound that contains magnesium and sulfate with numerous natural health benefits that are good for onions. It is an inexpensive, effective way to increase your crop size with little effort.

How Many Times Should I Water My Onion In A Day?
Everybody wants a good yield, be it a seasoned or a start-up gardener. As mentioned above, onions grow in all shapes and sizes. Water is an important component of plant growth especially if you’re looking forward to a decent yield.
Onions are shallow-rooted and need only a little water to survive. Depending on time constraints, you can choose to water them every day with a light sprinkle or once a week to a depth of 2.5cm. Seedlings usually need more water than the actual onion plant. However, keep in mind that overwatering will make the plant rot. For this reason, it is best to test the soil before you water it.
If the leaves of your plant start to turn yellow, it is best that you stop watering. This is a sign that the plant is starting to rot. Ideally, you should stop feeding your onion plants at least 8 to14 days before harvest. During this time, you should see the green leaves start to fall over which is a clear sign of maturity.
