What Are Mustard Greens For Bearded Dragons?

Mustard greens are another leafy green vegetable family that encompasses various different plants. The term mustard greens, when referring to keeping of bearded dragons at least, is most commonly applied to curled-leaf mustard or American mustard. Other subspecies exist across the world however and all are related if they are members of the Brassica juncea family.

The mustard plant is cultivated and grown across the world and the Brassica juncea is grown in the US, Canada, UK, Denmark, Bangladesh and India. It’s often grown in these countries to produce the seeds which are then ground into a spice, known as the condiment, mustard. Which, if you like that sort of thing, is delicious (and I do).

How Should I Feed Mustard Greens To A Bearded Dragon

Mustard greens can be fed as part of a balanced staple green leafy vegetable diet. You can mix them up with other vegetables and place them in a dish. Cut away any fibrous stems as they’ll be too hard and unappetizing for your bearded dragon.

The greens can be placed in the vivarium in the morning once your bearded dragon has warmed up (it’s best to let them bask for a couple of hours before feeding if possible) and can be left in place throughout the day. If they become dried out or mostly eaten they’ll need to be replaced.

You can dust the leaves with a good quality calcium supplement every few days.

How Much Mustard Green Should I Feed A Bearded Dragon?

Mustard greens can be fed every day. They should be placed in a suitable dish in the morning and can be left in the vivarium all day – replacing when they get too dry or have been mostly eaten. You’ll not overfeed mustard greens to your bearded dragon so don’t worry if they eat loads.

Mustard greens should be dusted lightly with a calcium supplement to increase the calcium content at least twice a week. They can also be lightly sprinkled with some water before being placed in the dish to help keep them a little bit more fresh throughout the day.

Place the mustard greens and salad mix at the cool end of the vivarium so that they last longer before drying out. Dried mustard greens aren’t going to be appetizing for your bearded dragon. You may find you need to replace them at least once throughout the day if your bearded dragon hasn’t eaten them before they go dry and wrinkly.

You should mix in other vegetables to give your dragon some variety, but there’s no upper limit on how much they can have.
