Weeds are broadly divided into broadleaf plants dicotyledons or narrowleaf plants monocotyledons. Most narrowleaf plants are grasses, but this group also includes sedges, such as yellow nutsedge, which are important weeds. Another way to classify weeds is by when they germinate and grow. Many common weed species are winter annuals, germinating mainly in fall, growing through winter and spring, and dying as summer approaches. Summer annuals germinate in spring, grow through summer and die as the temperature drops in the fall.
Irrigation can alter the germination time of weeds and prolong the life span of some annuals and delay their senescence. A few weeds complete a life cycle in 2 years and are referred to as biennials e.
Some of the worst weed species are perennials; weeds that live for 2 years or more. These include bermudagrass, creeping woodsorrel, and nutsedge that persist through their vegetative propagules stolons, rhizomes, or tubers. See the Common Weeds in Floriculture and Ornamental Nurseries table for a list of these and links to photographs and more information on them.
Growing site and production practices largely determine which weeds are likely to become problems at a site. For example, weeds commonly associated with container nursery production include creeping woodsorrel, common groundsel, lesser-seeded bittercress, northern willowherb, and prostrate and spotted spurge. Sometimes annual bluegrass, liverwort, or pearlwort are a problem.
In greenhouses, weeds that thrive in moist conditions often proliferate. These include liverwort, mosses, and pearlwort. In field sites, weed species vary greatly but the weed spectrum can be influenced by management practices in the field and by the environment. Because of these variations, each type of production situation is addressed separately in this guideline.

These plant families also happen to include the majority of the world's food and fiber crops. While this is not a key or identification guide, the information herein is intended to familiarize you with the world of weeds from a taxonomic identification and genetic relationships point of view, and to offer examples of some of the features to look for when identifying weeds. The world's flowering plants are divided into two sub-classes: the Dicotyledonae dicots , and the Monocotyledonae monocots. The plant embryo within the seed of a dicot has two cotyledons seed leaves , while the plant embryo of a monocot has just one Fig. When the seed germinates, the embryo becomes a growing seedling, and draws upon food reserves in the cotyledon s or the endosperm a nutrient-rich seed tissue that is not part of the embryo itself as it develops its first true leaves and an expanding root system. The true leaves often differ greatly from the cotyledons in shape and size. Dicot seedlings usually have a distinct primary root, which grows vertically down into the soil, sometimes becoming a taproot as the plant grows. Monocot seedlings tend to grow a cluster of several roots spreading out from the site of germination, which branch further to form a fibrous root system Fig. Figure 1.

Best known for their yellow flowers, dandelions have a thick tap root that is dark brown on the outside and milky white inside. Their long jagged leaves form a rosette lying close to the ground. A strong wind can carry away dandelion seeds miles away from its parent plant, traveling like tiny parachutes. The perennial white clover features white flowers and stems that root at its nodes. Its trifoliate leaves have three egg-shaped leaflets, each of which is widest at the apex with an indentation at its apex.
It is not only helpful to know which weeds are noxious but also what methods are effective in eradicating them. Here are a few items of interest regarding some of the more commonly found noxious weeds in our area.

Broadly speaking, weeds are plants in the wrong place. In beds and borders they compete with other plants for light, water and nutrients, making it harder for other plants to grow. Check out this advice on dealing with annual and perennial weeds. Nettles, for example, provide food for the caterpillars of red admirals, commas and small tortoiseshells. If you can, make room in your garden for an uncultivated patch where weeds can grow freely. Choose a tucked away spot so you can focus your energy on the more visible areas of the garden. Boost the biodiversity in these areas by creating dead wood habitats or a stumpery for insects.

Summer annual weeds emerge in the spring or early summer, grow during the summer, produce seed in mid to late summer, and are killed by frost in the fall.
