What Weed Is This in My Lawn? Free Lawn Weed Identifier - Identify Lawn Weeds by Picture Online Free

Photograph the weed from above and upload it, and the tool returns the most likely scientific name. Common answers include Taraxacum officinale (dandelion), Trifolium repens (white clover), Digitaria (crabgrass) and Glechoma hederacea (creeping Charlie).

Crabgrass has wider, lighter green blades than most lawn grasses and grows in low, sprawling clumps that spread outward from the center. It is an annual that dies after the first frost, leaving bare patches.

Both have scalloped leaves and small purple flowers. Creeping Charlie spreads with long runners that root along the ground and smells minty when crushed, while henbit grows upright from a single base and has leaves that wrap around the stem.

Most common lawn weeds are not a major risk, but some, like creeping Charlie, can be mildly toxic to horses and other animals in large amounts. The bigger danger is often weed killers, so keep pets off treated lawns as the label directs.

Many broadleaf weeds such as dandelions flower in spring, while crabgrass germinates as soil warms in late spring and is most visible in mid to late summer. Identifying weeds early makes them easier to manage.
