Abstract
A plant trimming guide apparatus, including a plurality of guide blades made of a resilient material, and a flat collar having a length, a width, an attachment surface, and made of a resilient material. Each of the plurality of guide blades has a pivot end that is secured pivotably with a common securement pin, and an opposed based end, with the plurality of base ends attached to and extending from an attachment surface of the collar, in a series along the length between the first end and the second end of the collar. Securing the first and second ends of the collar into a formed ring with the attachment surface facing outwardly causes the guide blades to extend radially from the common pivot ends and bend semi-spherically to the base ends, forming a spherical trimming guide.
