And you have to burn it in the winter because it won't die otherwise and it just spreads. (I am actually watching some burn as i type this for that reason.) Pulling it isn't enough. It roots multiple places, breaks off, etc.
Blackberry and dandelion can be tough but I can and do eat and use them. (I can understand why others don't feel as I do.)
Today Hank talks with Dr. Cara Nelson about invasive plants that use toxic chemicals and rapid reproduction to outcompete native plants, and Jessi brings some adorable invasive birds. Dr. Nelson is a professor of Restoration Ecology at the W.A. Franke College of Forestry and Conservation, University of Montana.

Mulch with cardboard (not the best, but solid enough) covered with 10+cm of normal mulch seems to keep it from sprouting. I’ve heard rumors of lawn rollers covered with yoga mats, but haven’t tried that yet.

Wild Parsnip (Pastinaca sativa) is a big problem here. It's an invasive, and a relative of the feared Giant Hogweed. It grows up to 6' tall, and the sap of the plant will cause extreme photosensitivity in skin - if the sap is exposed to UV rays while on your skin, you get more or less immediate blisters. When they leave, you often have a dark spot on your skin in that area for a couple of years, and lifelong photosensitivity in that area. If the sap gets into your eyes, it can cause blindness - this has happened to both children and adults alike - a lot of people will use a string trimmer on them without knowing the danger of the spray that gets generated.
The root is edible apparently, but still has a low concentration of the irritant that is in the sap. For some people, it's fine, others get mouth blisters. I haven't tried it to see which group I fall into.
It will grow anywhere with adequate sun. It's in all the roadside ditches, field boundaries and wherever else around here. It's all over my property, and it means that I need to strictly control the areas my children go in the summer.
The frustrating thing is that the province has declared it a noxious weed, and landowners are technically required to control it on their property or face fines. But the municipalities don't do anything about it on all the roadside ditches and common areas, so the seeds just blow in every year thick and heavy.
We live in a rural area, and if one of my kids was to have their bike go off the road into the ditch, they would be covered in the stuff.
There's few plants I would ever advocate spraying for, but this is one.

It makes my face swell when working around it’s blooms.

Have you had these same reactions when handling cultivated Amaranth?
By the way, the human reaction to poison ivy (Toxicodendron radicans) is also actually an allergic reaction.

Brace yourself while corporate america tries to sell us its things. Some day they will chill and use tiny ads.
