which weeds have seed on stem under the leaves

A weed can be any plant growing where you don’t want it to, but there are some particularly weedy species to keep an eye out for. These aggressive plants choke out the garden plants you’ve worked so hard to grow. Use this handy guide to identify weeds by photo and know how to best remove them.

Appearance: This garden weed has light green leaves that look like clover and cup-shape yellow flowers in summer and fall.

Where It Grows: Sunny or shady landscape, lawn, or garden areas

Appearance: This common lawn weed has a strong taproot; leaves are deeply notched. Yellow flowers mature to puffballs. Dandelion seeds are like parachutes that fly away in the wind—they’re the plants that you would blow on and “make a wish” when you were younger.

Don’t let these pesky plants crash your garden party!

Successful weed management is a combination of proper weed identification and timing of herbicide application and/or other management approach. The smaller the weed size (usually less than 5 inch), the increased likelihood that the post-emergence herbicide applied will be more effective with control. Weeds are broadly classified into two categories, monocot (grasses) and dicot (broadleaf) weeds.

Monocot (aka grasses) seedling identification can be challenging. Careful attention to detail is critical in proper identification as each step in the key is evaluated. In the key, check the drawings for key terms and structures you need to know to successfully identify these plants.
