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.
This species is a perennial weed that has a strong garlic or onionlike odor when cut. It is one of the first weeds to emerge in early spring. Wild garlic produces long, slender, mostly hollow leaves that are dark green and covered by a waxy substance.
