height. Sweet clover can bloom even at a height of 6 inches, but if it is burned or mowed in the following year in the late spring, it should be controlled. On steep sites, brush cutting can be substituted for mowing. Individual plants or small populations can be removed by hand -pulling. If seed production occurs, prodigious amounts of seed can be produced and spread, so pull before seeds appear or bag seed producing plants. Competition from native species also helps control sweet clovers and other weedy annuals and biennials. To some extent, Common burdock and common mullein can be treated similarly to sweet clover, since they are both exotic, biennial forbs that are typically found ig disturbed areas or restoration projects. rnri;- mustard Garlic mustard is an exotic biennial forb of woodlands and invasive and aggressive.

This can be difficult, since to break off at ground level. Chemical control i7w recommended except in cases where garlic mustard is growing in large monoculturalfatches. In such cases, a systemic herbicide may be appropriate. . Glyphosate is non-specific, and will kill any actively growing plant. One technique that has been effective is applying a water soluble herbicide during warm days in the winter, when no snow cover or only a thin snow cover exists. Garlic mustard rosettes (first year plants) remain green mostly all year round, and can be killed during the winter when nearly all other plants are dormant. Another successful technique is to use an herbicide specific to broadleaved plants, like triclopyr ("Garlon"), but one that is water soluble, which can be dispensed with a backpack sprayer or the like; this will not kill grasses or sedges.
