On Test: Lawn Weed, Feed and Moss Killers

By May 29, 2018Articles

Give your lawn a boost with a combined feed, weed and moss killer treatment.
There are both chemical and organic formulations to choose from, says Tim Rumball

Weigh the appropriate amount of products, make a 1m sq measure with canes, lay it on the lawn and sprinkle evenly over the area. Note coverage, and spread the rest evenly over the whole area at a similar density

LAWNS don’t have to be hard work to keep in good shape. Regular cutting plus a combined feed, weed and moss treatment a few times a year from April until August will give you a sward to be proud of.

Ten years ago most combined treatments were based on chemicals. They work quickly and effectively, but demand from gardeners for a greener approach has resulted in a range of organic alternatives.

Organic treatments (which can be smelly!) generally work on the basis of promoting grass health and strong growth to out-compete weeds and moss, so their effect on these undesirables is likely to be slower. However, they will save you the job of raking out dead moss, which is a feature of fast-acting chemical treatments.

With organic treatments there’s also no need to compost clippings before using them as a mulch. Packs with a built-in spreader are easy to apply,
while for the others you need to buy a calibrated spreader or make careful measurements.
