In this article, we will be answering some of your frequently-asked questions on this subject, as well as give you tips and tricks on how to manage and use them. Soon enough, you will be handling onion grass like the skillful gardener that you are.

Without further ado, let’s get right down to it!


1. What Is Onion Grass?

Also known as “wild onion,” onion grass is a type of perennial weed and to be suitable for many type of soil, especially thrives in heavy soils. It is relatively hardy, able to withstand anything from cool weather to even drought.

That said, onion grass is a particularly resilient weed. It is given its name due to its spring-onion form (i.e. long, tall, and thin roots) and onion-like smell when broken and crushed.

2. Is It Harmful To Plants?

Like with any weeds out there, onion grass can adversely affect plant growth in your backyard, especially if you do nothing to get rid of it.

Even worse, onion grass can spread rapidly, due to the fact that it propagates through a number of different ways: dropping seeds, growing bulbs underground, etc.

Indeed, it is a vicious weed, and without taking any action to stop it early on, the more difficult it will be to remove them later down the line.

3. How Do You Remove It?

Considering its festering, rapid growth, onion grass is definitely one of the harder weeds to get rid of in your garden. However, the best thing to do is to detect the growth early on, so that you can take measures to destroy them before they spread even more.

A general rule of thumb is to keep your soil well-aerated, so that your plants can receive enough nutrients and be strong enough to fight against the weeds, if need be. As for getting rid of the already-present weeds, it is best not to pull them out, since if you accidentally miss any part of it, the onion grass will be sure to grow again at a fast rate.

Otherwise, it is advisable to regularly mow or trim your lawn: this process slows down the growth of the budding weeds and it gives you more time to consider getting herbicide to blast them away.

However, make sure that you get a brand that does not kill off the plants themselves, and once the onion grass have been eliminated, you will have to check closely to see if any of them remain, for extra good measure.
