How To Feed Lemongrass To Guinea Pigs

When it comes to lemongrass, you can either feed them the herb fresh or mix it with other foods.

Feeding them Fresh Lemongrass

If you’ve grown some lemongrass in your garden, start by cutting at the bottom of the stalk. At the top of the stalk where the leaf starts at, cut off the leaf from it.

Then peel the outer layer off the herb. This is a hard layer that the guinea pigs won’t be able to chew through. You may have to peel another layer under it if there’s another one.

Once all the layers are peeled, you’re left with the soft part of the stalk. You can give them the entire lemongrass stalk or cut them into smaller pieces.

Mixing with Other Foods

You can mix the lemongrass with other food or pellets. This is a great way to give them a boost in nutrition.

Cut or slice the lemongrass into tiny pieces and mix it into their food. The guinea pigs probably won’t notice any of the herbs.

How Much Lemongrass To Feed Guinea Pigs?

If the guinea pig has an allergic reaction, it will either have diarrhea or an upset stomach. Stop feeding them lemongrass.

On the other hand, if the guinea pig doesn’t have any allergic reaction, and they seem to like it, you can continue to feed them.

Guinea pigs should only be fed lemongrass in moderation. This is due to the citronella that’s in the herb.

Also, lemongrass doesn’t have a lot of nutrition that guinea pigs require each day. Like other herbs, lemongrass should only make up 10% of their entire diet. The rest should come from quality pellets, hay, and fresh vegetables.

About 1/8 cup of pellets once a day, some vegetables, and an unlimited amount of fresh timothy hay should be provided for them.

Therefore, lemongrass can be fed to them, once or twice per week.
