Castaway Soil Enhancer is not just a fertilizer. Herrick advised that if gardeners wanted to try using saponin-rich plants, that "applying them as slurry or some way that would breakdown quickly with irrigation is key. Marie Johnston, an honorary fellow in the UWMadison Department of Soil Science, and I recently completed a study investigating the thermal tolerance of jumping worm cocoons. Jumping worms replace soil with their worm castings, which are small, loose, hard pellets, resembling spent coffee grounds. Rather than create a casting pile or middens like European earthworms and night crawlers, jumping worms will leave loose, granular soil particles with the same consistency as spent coffee grounds. They can move across the ground in an S pattern like a snake. Some sources suggest allowing the bag to sit in the sun to kill the worms first. These worms, which can reach 6 inches in length, are much more active than European nightcrawlers.

In addition, a new-to-Wisconsin species of jumping worm, Metaphire hilgendorfi, was discovered at two residential properties. Variously known as jumping worms, snake worms, Alabama jumpers, and Jersey wrigglers, common Amynthas species are a super-powered version of the more familiar, squishy languidness of the garden . Jumping worms are noticeably fast moving, highly active worms with a strong rigid . In addition to Amynthas agrestis, researchers report a co-invasion of closely-related Amynthastokioensis and Metaphire hilgendorfi. Using innovative, sustainable techniques, Ocean Organics produces seaweed-based products that are richer than others but with fewer solids and inert ingredients. By changing soil characteristics, they contribute to a number of other ecosystem shifts that may ultimately increase allergies and Lyme disease, reduce crop and forest productivity, and reduce forest biodiversity. One of the most common species in the United States, and probably what you had, is Gordius robustus, also named the Gordian knot. I contacted one of the leading researchers on Asian jumping worms, Brad Herrick, and he reported that In our small trials with Early Bird (saponin based fertilizer), we found that it was extremely effective at killing jumping worms, but direct contact was needed. These invasive worms are members of the genus Amynthas and live in the organic matter or the topmost layer of soil. Here is what we know about various treatment ideas: Early Bird fertilizer: This is a fertilizer. This research indicates that tea seed meal, a natural by-product of tea oil manufacture, and containing natural surfactants called saponins, is effective for expelling earthworms and suppressing casting on playing surfaces. The mode of action is similar to that of mowrah meal, a mainstay for managing earthworms on golf courses a century ago. Tea seed meal has been formulated into an organic fertilizer (Early Bird 3-0-1) suitable for use on fairways and putting greens by Ocean Organics Corporation. It wiggles like mad when touched, making it extremely difficult to catch and giving it many wiggling and jumping common names.

Tea seed oil, pressed from seeds of the Chinese tea oil plant, is used for cooking in eastern Asia, and in soaps and shampoos, margarine, ointments, and other products. Although tea oil websites claim efficacy for earthworm control, a 2007 search of the worldwide scientific literature found no references or data supporting that claim.

Earthworm-toxic soil insecticides, like diazinon, bendiocarb, and carbaryl, have been replaced by chemistries that are more selective., This article describes a promising new approach to managing excessive earthworm casts on golf courses using tea seed meal, a by-product of tea oil manufacturing that contains natural surfactants called saponins., Early turf culture evolved in rainy Great Britain where earthworms are very abundant. Rolling was the main management practice before 1890, but it was eventually recognized as having negative effects (e. g. soil compaction). Two other main approaches evolved; one based on cultural control and the other on chemical control that uses pesticides or expellants (6).. Research is moving forward on understanding jumping worms and developing ways to manage them in a yard and garden setting. 2023 The research on earthworms generally and biochar found there is a limited short-term negative impact on earthworms and no long-term negative impact on earthworms when using biochar.

These non-native earthworms (introduced from Europe) usually range from 2-3 inches and create mostly horizontal burrows in soil. The cocoons, which are about the size of a mustard seed, will survive the winter and hatch in mid-April after temperatures reach 50F for a consistent period. , Many of the turfgrass pesticides used from the 1970s to mid 1990s were acutely toxic to earthworms and suppressed them when applied for grub control (12). Most of the older worm-toxic pesticides have been cancelled, although two that remain are still sometimes used off-label to suppress worms and casting. There presently are no pesticides labeled for earthworm control in the United States., Another widely used approach used for earthworm and cast suppression from early in the 20th century until about 1960 involved the use of chemical expellants (6). The method, pioneered by British greenkeeper Peter W. Lees during the 1890s, was so effective that it had become the mainstay for earthworm suppression on European and United States golf courses by the 1920s (4, 5, 7, 8, 9).
