How is the Spreader L used and for what purpose?

When it comes round to the time to fertilise your garden again, the GARDENA Spreader L is your best option. You can use it to conveniently apply the optimum amount of fertiliser or even road salt over medium-sized areas. It is easy to operate using the open/close function on the handle, on which the spread rate can also be adjusted. The cover slide with sealing lip seals the spreader so tightly that nothing trickles out when standing, filling or after use. The special spreader roller within the GARDENA L Spreader distributes the product completely evenly, cleanly and exactly where you want it to go. The spreader can easily be cleaned with water.
