Dangerous Plants: Wild Parsnip | Your Garden GalOntario has been invaded by several noxious weeds that can be quite hazardous to your health. From the age-old poison ivy to stinging nettle, Ontario is no stranger to plants that strike back! One of the most dangerous and also the most invasive is the dreaded Wild Parsnip. It’s reported that wild parsnip has been noted in every province in Canada as early as 1943. However, it really only began to take a serious hold by 2011-2012. By 2015 it was officially placed on the Noxious Weed list.

Wild Parsnip is part of the carrot family. While the root of the plant is, in fact, edible, the rest of the plant causes various degrees of dermatitis. The chemical compounds of the plant react with sunlight on your skin and cause inflammation and third-degree burns. They are biennial plants which means they take 2 full years to complete one life cycle. The first year they are simple green juvenile plants with no flowers or seeds. However, in their second year of life they will flower, as well as seed and then die. They can only reproduce by seed so if you can rid of these plants before they seed, you will minimize their ability to spread. Knowing the stages of life and reproductive capabilities of this weed will help you eradicate this weed on your property and help to keep you, your family and pets/wildlife safe.

Eradication of Wild Parsnip

There are several modes of transportation that wild parsnip seeds can take. It can be carried to your property by the wind, wildlife, motorized vehicles such as trucks, ATV’s and tractors and even by you! On the bottom of your shoes, the cuff of your pants. Light-weight plant seeds can travel quite the distance. This makes it extremely difficult to completely eradicate but there are ways to help lessen the spread!

Some will tell you that in order to stop the spread that you must spray the cancer-rich product ‘Round Up’ by Monsanto. This is in fact not true. With some diligence, persistence and patience you can drastically lessen the parsnip population. Keeping in mind that one fully mature plant can drop up to 950+ seeds – I really stress that you need patience lol.

The key is to pull them out. One by one. Removing them at the taproot of the plant in early to mid-July before they get the chance to seed. This will lessen that plant’s opportunity to spread to zero. Since these are biennial plants, after a few short years of completing this task – you’ll eventually just lessen the population down to whatever blows in by the wind, which will be minimal and controllable.

Yes, it takes a lot of time and patience – this is a no-chemical way to help minimize and eradicate the species. It’s probably your best hope but also the most dangerous if you do not know what you are doing. Because you have to touch these plants, there is a high risk of exposure to its noxious traits if improperly handled – if you are unsure, you should always call a professional.
