Can Turtles Eat Sunflower Leaves? Are They Dangerous?


Can Turtles Eat Sunflower Leaves? Are They Dangerous?

Turtles are known for eating everything that you put in front of them. This is generally a good thing since they won’t refuse the food you give them. But this can also be dangerous because they might eat some fruits or vegetables that are not so good for them. But are sunflower leaves one of them?

Turtles can eat sunflower leaves, but should only eat very small quantities. Sunflower leaves contain phosphorus which inhibits the absorption of calcium, which is essential for the good health of the shell.

So sunflower leaves are not the best thing to feed your turtle. But they are not the only thing that seems harmless at first but should actually be avoided, the same thing applies to a lot of vegetables.

What Else You Should Avoid Feeding Your Turtle, Besides Sunflower Leaves

Almost all vegetables contain calcium and phosphorus. And as a result, most of them have a calcium to phosphorus ratio. So let’s take a look at what calcium does for turtles, what phosphorus does for them, and what is good calcium to phosphorus ratio is.

Calcium is essential for every animal in this world that has bones. And since the shell of a turtle is made out of bones, the calcium is even more important for turtles than for any other animal. Vegetables are one of the main sources of calcium that a turtle has, so making sure that you feed them vegetables with high amounts of calcium is important.

For humans phosphorus is a very important mineral that helps filter waste, repair tissue and cells, etc. But for turtles phosphorus is not that great. Phosphorus is what gives turtle shells a little flexibility, which is great because this little extra flexibility makes them more resistant to bites and other types of impact. But too much phosphorus can also make the shell a lot softer, and as a result much weaker when it comes to defending the turtle from predators.

In short, we can say that calcium is great for turtles and phosphorus is not so great for turtles in high quantities.

Most vegetables have a calcium to phosphorus ratio, this ratio can be 1:1, 2:1, 5:1, 1:2, etc.

A 1:1 ratio means that the amount of calcium is equal, or almost equal to the amount of phosphorus. So a vegetable with this ratio is not that great for turtles, but it’s not harmful either. But if possible such a vegetable should be avoided.

A 1:2 calcium to phosphorus ratio is bad, there are not many vegetables with this ratio, so don’t worry too much about them. Just remember that if a vegetable has more potassium than calcium you should keep it away from your turtle.

A 2:1 ratio is great, and this is what you should be aiming for, if the ratio goes higher it’s ok, but ideally this is the ratio that you are looking for.

With the help of this table you should be able to get a general idea of what vegetables you should feed your turtle. I personally like to feed my turtle Greenleaf and Redleaf salad, they are not too expensive and he seems to like it. And when I’m cooking something with vegetables I usually cut a couple of smaller pieces and feed them to my turtle, just to mix things up a little.

Fruits are somewhat similar to vegetables, so they also contain phosphorus and should be eaten by turtles in moderation.
