Waging war on dandelions, which have deep-reaching taproots and are easily fertilized, has often resulted in defeat. To identify shepherd’s purse from dandelion look at the lobes in the rosette leaves, if the leaves come to points towards the center of the rosette, it is a dandelion3. Even hay with a small amount of contamination can be problematic as pyrrolizidine alkaloid poisoning can accumulate in the livestock over months of feeding. At bolting, horseweed sends up a single, erect stem upon which flowers are produced. Hairy fleabane (also called asthma weed and flax-leaf fleabane)is an annual (sometimes biennial) herb that is not native to California. Whereas single hairy fleabane plants have been estimated to produce up to 20,000 seeds per plant, horseweed plants can produce more than 200,000. Hairy fleabane populations with resistance to glyphosate and with resistance to both glyphosate and paraquat have been confirmed in California. Dandelion only has one flower per stalk. Photo by L. M.

Apply to newly seeded or sprigged turf after third mowing or when tillering and secondary root development has occurred. The youngest leaves are egg-shaped with shallowly-toothed edges, the base of the leaves may be purple on the underside. On the other hand, dandelions brighten up their environment with their shining yellow flowers, especially at the beginning of summer, and blowing the seeds from the clocks is a source of great fun later on for children, and adults who are young at heart.

Dandelion root and leaves have a cleansing and purifying effect on all major body systems. In the early spring, new sprouts will emerge from the taproot, which can … Species differ with respect to their emergence timing, life history traits, competitive interactions with the crop, potential to harm livestock, and sensitivity to available herbicides, among other characteristics. Flowers (0.3 to 0.4 inches [8 to 10 mm] in diameter) are pale yellow; flowering occurs, typically, from April to October. Individual flowers are approximately ½ to 1 inch in diameter and are grouped together in clusters.

The health benefits of dandelion greens cannot be overstated. The common dandelion (Taraxacum officinale) is a prolific intruder of lawns, primarily blooming in spring with an encore appearance in fall. The separation was partially based on genetic studies. This blog post has been developed to help you distinguish among these species. Individual seeds possess a pappus (0.12 to 0.16 inches [3 to 4 mm] in length) on one end that facilitates wind-dispersal. The first leaves are football-shaped; later leaves are elongated and club-shaped with weakly-toothed margins or are deeply- and pinnately-lobed with rounded indentations. Properly identifying these and other species is the first step in developing a safe and effective weed management program in crop production systems.
