Rhubarb is a plant that is known for its tart and tangy stalks, which are commonly used in pies, jams, and other delicious desserts. However, despite its delectable taste, rhubarb is not a favorite food of deer or rabbits. In fact, they tend to avoid it due to its toxicity.
One of the main reasons why deer and rabbits stay away from rhubarb is because of the presence of oxalic acid in the leaves. This compound acts as a natural deterrent for animals, as it can be toxic if consumed in large quantities. Even a small amount of oxalic acid can cause digestive issues and kidney damage in deer and rabbits.
I have personally experienced this aversion to rhubarb in my own garden. I used to have a problem with deer grazing on my vegetable patch, but they would always bypass the rhubarb plants. It was as if they knew instinctively that it was not a suitable food source for them. This was a relief for me, as I could enjoy growing rhubarb without worrying about it being devoured by these pesky critters.
It is important to note that while the stalks of rhubarb are safe for human consumption, the leaves should never be eaten. The high levels of oxalic acid in the leaves can be harmful to our health as well. It is always best to err on the side of caution and discard the leaves when preparing rhubarb for culinary purposes.
In addition to the toxicity of the leaves, the texture and taste of rhubarb can also deter deer and rabbits from consuming it. The stalks are quite fibrous and have a strong, sour taste, which may not be appealing to these animals. They tend to prefer tender, leafy vegetation or sweeter fruits and vegetables.
If you are concerned about deer or rabbits damaging your rhubarb plants, there are some additional measures you can take to protect them. One option is to install fencing around your garden or individual plants to create a physical barrier. This can be especially effective for rabbits, as they are smaller and more likely to be deterred by such obstacles.
Another option is to use deer or rabbit repellents, which are available in various forms such as sprays or granules. These products typically contain natural or chemical ingredients that emit odors or tastes that are unpleasant to animals. However, it is important to follow the instructions carefully and consider the potential impact on other wildlife or pets in the area.
Deer and rabbits are unlikely to eat rhubarb due to its toxic leaves and unappealing taste. The presence of oxalic acid acts as a natural deterrent for these animals. While this can be a relief for gardeners, it is crucial to remember that the leaves should never be consumed by humans either. Taking additional measures such as fencing or repellents can further protect your rhubarb plants from potential damage.
