On another thread dtd and I were discussing the current (within the last two years) INVASION of the annual weed Cardamine hirsuta Hairy Bittercress to both of our properties. After a little poking around I learned that this weed can mature in a matter of weeks and produce seed, if it is happy (moist conditions), it can produce several generations in a season. Hairy Bittercress is usually considered an annual but if the seeds germinate in the autumn it can be biennial. Dtd learned What I read about this pest is that anyone who doesn't have it yet will, soon, at least if they buy any plants other than bare root ones. It's infested the wholesale potting soil supply and can be found at just about any nursery that buys stock from off-premises. Cold comfort, I guess, but we're all in this together, or we will be soon. I was shocked to discover in my garden this weed no older than two weeks and a total of 1" tall in flower which means that this very young plant would have been dispersing seeds in another week or so. In a very short period of time this plant has taken over my lawn, woodland, garden beds, walkways, and planters. Dtd plans on using the pre-emergent corn gluten to attack the problem but to be honest I am still in panic mode not sure what to do. My sister in Fla. who has this problem as well suggested I surrender to the mighty Bittercress and consider it a groundcover, a friend suggested that since it is eatable that I should make my fortune by becoming a Hairy Bittercress Farmer. What is your experience with this monster???
