An apparatus for performing a ground treatment, such as aeration or dethatching, is provided. The apparatus includes a base frame component to which a pair of angled side frame components are pivotally mounted. Each angled side frame can include first and second ends that are oriented to form a central angle. A first end of an angled side frame can be pivotally attached to a wheel and/or the base frame component, while the second end can include a mechanism for mounting a ground treatment component.

A handheld gardening tool includes a power source, a spike projection device adapted to roughen soil for the application of grass seeds or to ease pulling weeds, and a support arm connecting the power source to the spike projection device. The spike projection device comprises a housing supporting a plurality of spikes mounted within the housing for controlled extension from and retraction within the housing for engagement with soil.

An aerification system for controlling moisture content and gas exchange below a surface of one or more plant growing areas includes at least first and second sub-systems installed below the surface of the one or more plant growing areas. The first and second sub-systems each having a water permeable layer overlying a respective water impermeable layer, where the water impermeable layer defines a respective boundary of each of the first and second sub-systems. The system also includes at least one conduit connecting the water permeable layer of the first sub-system to the water permeable layer of the second sub-system, and at least one pumping system for pumping water therebetween. The pumping system is configured to alternate between pumping water to the first sub-system and the second sub-system in order to periodically raise and lower a water level in the water permeable layer of each of the first and second sub-systems.
