Frequently Asked Questions

1. Which fertilizer is best for onions?

There are a few different types of fertilizer that can be used on onions, but the best type to use depends on the specific needs of your onion plants. If your plants are young and just starting to grow, you should use a fertilizer with a higher nitrogen content. This will help promote leaf growth and make your plants strong and healthy.

If your plants are already established and you’re looking to encourage bulb growth, then a fertilizer with a higher phosphorus content would be a better choice. Whichever type of fertilizer you choose, make sure to follow the instructions on the package carefully so that you don’t end up over-fertilizing your onions.
