Noxious & invasive weed: Common Baby’s Breathe

Noxious & invasive weed: Common Baby’s Breathe (Gypsophila paniculata)

DO NOT HAY THIS PLANT!  IF YOU SEE THIS SPECIES IN DITCHES OR HAY FIELDS, GO AROUND!!!!

Most people are familiar with this ornamental plant, particularly in flower arrangements.  What most people don’t know is that in 2010 it was listed as a NOXIOUS Weed in the Weed Control Act.  This means it MUST BE CONTROLLED.

This perennial reproduces by seed only (1000’s per plant) but spreads easily through its tumbleweed nature. Commonly found in hay fields surrounding old homesteads and cemeteries, this noxious weed is a moisture thief with its enormous tap root often extending 4 metres.  It competes very well against hay crops and can rob crops of precious moisture, particularly in drought years.

The first step in battling Baby’s Breathe is to prevent seed set.  Mowing prior to seed set (BEFORE you see those white flowers), combined with a selective herbicide will be your best chance at controlling the population long term.  Also, physically damaging the root (by chopping), down to at least 3 inches is a good idea.  Pulling the entire root is near impossible because it can be up to 4 metres deep!  Because of this deep taproot, fall is an excellent time to apply herbicide to translocate deep into the root system.  You must be very diligent not to let the plant flower before then though!  This weed is common all over the Special Areas, so scout your hay fields often and carefully.
