A power cultivator including a power source, a shaft and a cultivating head having a pair of cultivating blades is described. The cultivating head includes an assembly that opens and closes the blades using a mirrored arcuate motion. The cultivating head itself is also part of the invention in that it can be attached to a standard string trimmer in place of the standard string trimming assembly. The power cultivator is effective at cultivating small areas of soil, in which a gardener usually uses a common goose-neck garden hoe.
