The right tool for a strip, a patch or a spot repair — and the wrong tool for a lawn. Some product labels prohibit handheld application outright, so read the bag before assuming this can apply it.
Genuinely useful within its range: a bare patch, a strip along a fence, seed into a repaired area, or ice melt on a path. It is not a lawn spreader, and the rate consistency of a hand crank cannot match a wheeled unit walked at a steady pace. One thing that catches people: certain pesticide labels forbid handheld or chest-mounted application — the trichlorfon grub curative we review is one of them — so the applicator can make a legal product unusable.

Product Reviews
Penn State: every spreader differs from every other and must be calibrated separately. So buy the machine that holds a rate, not one that arrives with it.

Product Reviews
Rotary spreaders are faster, drop spreaders are exact — and the deciding factor is what borders your lawn. Plus the 10-minute calibration both types need.

A bare spot smaller than your fist closes on its own. The bigger ones are a symptom — and the shape of the spot tells you which cause to fix first.
