I asked what they were fertilizing with (thinking they were applying too much nitrogen), and to my surprise both replied: 10-10-10. I said, That'll do it.. What I don't know is why anyone would think 10-10-10 is fine for their gardenâor how to help them fix the problem they've caused.
Garlic mustard (Alliaria petiolata) is a cool-season biennial herb that may reach up to 4 feet in height at maturity. Both the stems and leaves have a strong onion and garlic odor when crushed.It is this odor, particularly noticeable in the spring and summer, that helps to distinguish mustard weed from other mustard plants commonly found in woodlands.hen infestations are small, hand-pulling plants is the best way of killing garlic mustard. Pull plants early in the season before they flower. Also, pull plants, being sure to get as much root as possible, while the garlic mustard weeds are small and the soil is wet.
Alliaria petiolata is a biennial flowering plant in the Mustard family, Brassicaceae.It is native to Europe, western and central Asia, and northwestern Africa, from Morocco, Iberia and the British Isles, north to northern Scandinavia, and east to northern Pakistan and western China (Xinjiang).epending upon conditions, garlic mustard flowers either self-fertilize or are cross-pollinated by a variety of insects. Self-fertilized seeds are genetically identical to the parent plant, enhancing its ability to colonize an area where that genotype is suited to thrive.
