RASENBLITZ is a lawn-care brand featured in an advertorial promoting a liquid spring fertilizer made in Germany. Its flagship product, RASENBLITZ Frühjahrsdünger, is presented as a concentrated formula derived from fermented organic and green waste, with nutrients tailored to lawns recovering after winter. The advertised blend includes nitrogen, sulfur, phosphorus, potassium, magnesium, and iron, intended to support growth, nutrient uptake, root strength, and green color.

The fertilizer is applied using a spray head connected to a garden hose, rather than a spreader, and is promoted for quick, convenient treatment of lawns of different sizes. The page claims visible results within seven days and says the lawn can be used once dry. Product sizes are listed for areas from 100 to 1,000 square meters; some options include a spray bottle and grass seed. The advertorial also mentions free shipping, a 100-day money-back guarantee, and RAL certification. These benefits and performance statements are promotional claims in the supplied material, not independently verified information.
