Dig By Hand

Onions grass grow in clumps, so here’s a way to deal with it without having to use too much effort: remove the first onions grass you see using either a weeding fork or manure fork.

Then, be sure to pull out the entire onions grass plant – roots and all – and discard it in the trash so that its seeds don’t become airborne and spread.


The best way to take out onion grass is by using a non-selective herbicide or boiling water. Both of these liquids destroy any neighboring plants with which they come in contact.

So it’s best to mark the affected area with flattened cardboard boxes so as not to get any textiles mixed up in the process of taking out these unwanted weeds.


After hand-pulling existing onions from weeds:

Use a glyphosate to destroy additional seedlings in the area, like dandelion or crabgrass. This method can be effective before or after planting the onion bulbs, but it has to be done on a warm, sunny day.

Follow packages instructions and keep in mind that glyphosate is a broad-spectrum herbicide to kill not just weeds but also other plants like grass.

Check back after three days to see if the grass begins to wither and reapply if needed.

Stay Vigilant

Maintain a constant watch on your grass and take immediate action once you see the first signs of onion grass.

Pulling the bulbs in small patches is a great place to start. Another tactic is to apply glyphosate twice a year as a preventative measure.

Because onion grass is perennial, these applications should be performed in late fall and again in late winter.

How can you Harvest Onions & Get Dirt Off?

When harvesting onion bulbs, make sure to begin after the leaves have turned yellow.

The cultivated varieties of onions can be classified into three types primarily based on their pungency level – mild yellow or white varieties, sharp red ones and storage onions.

Green onions are harvested as immature plants, while bulb onions are dug up, cured and processed (rather than eaten raw).

Bulb onions tend to store more successfully than green ones and don’t need any washing at all, although it’s highly recommended you remove excess dirt before storing them to avoid making a mess.
