The present disclosure relates to a plant protection device having two substantially hemispherical portions, two rim portions, each attached to a perimeter of one of the substantially hemispherical, two connectors capable of attaching the two rim portions and the two substantially hemispherical portions to each other in a substantially a spherical shape, a first opening in one of the two substantially hemispherical portions, and a second opening in one of the two substantially hemispherical portions. The first opening and the second opening may be positioned to accommodate a first and a second portion of branch or plant part, respectively.

A biodegradable layered composite includes at least a first layer and at least a second layer. The first layer of the biodegradable layered composite includes a paper layer having a top surface opposite a substantially planar and parallel bottom surface. The second layer of the biodegradable layered composite includes a non-woven polymer layer having a top surface opposite a substantially planar and parallel bottom surface. The non-woven polymer layer is bonded to the paper layer, forming the biodegradable layered composite. The biodegradable layered composite allows for at least one root of at least one seed to penetrate and grow through both of the paper layer and the non-woven polymer layer of the biodegradable layered composite.

A plant raising apparatus: a light source that emits light traveling toward an aboveground part of a plant; a heat insulating portion that has a light transmitting property and that partitions a space at a side of the light source and a space at a side of the aboveground part; and an air blowing mechanism that generates an airflow at a space between the light source and the heat insulating portion. Thereby, it is suppressed that the heat of high temperature air staying above the heat insulating portion having a light transmitting property adversely affects the plant.

Disclosed is a grass protection mat including: a plurality of bodies formed with grass passing spaces; and one or more contraction-expansion compensatory connector(s) connecting the plurality of bodies and compensating for contraction or expansion of the mat units.

A method and system for inhibiting the growth of unwanted plants at and about the base of trees, shrubs, and other ornamental and/or commercial plants; while providing protection to the trunk, stalk, root crown, and/or plant roots from damage inherently caused by mulching material itself, and from damage caused landscaping or cultivation techniques, while promoting the oxygenation of the plant, and additionally avoiding and/or treating pathogen infection or infestation of the plant.

An adhesive pest trap is provided, that includes: a substantially planar substrate having first and second substantially parallel surfaces and an outer perimeter, wherein the first surface includes a non-drying adhesive material coating, and wherein the outer perimeter is configured for fitting within a rim of a plant growing container. In one example, an adhesive pest trap can be adapted to cover a soil surface in a plant growing container, where a perimeter of the adhesive pest trap additionally includes one or more attachable surfaces adapted for attachment to a rim of a plant growing container. A related method of using an adhesive pest trap includes applying the adhesive pest trap over a top surface of a plant growing medium in a plant growing container.

A tree guard assembly includes a plurality of corner sections, each corner section including a first wall with a first flange comprising at least one flange aperture, the first wall includes an opening configuration pattern and a second wall with a second flange including at least one flange aperture, the second wall meets the first wall at a corner.
