Straw, rushes, or the like, used for making or covering the roofs of buildings, or of stacks of hay or grain.
To cover with, or with a roof of, straw, reeds, or some similar substance; as, to thatch a roof, a stable, or a stack of grain.
A mat of un-decomposed plant material (as grass roots) accumulated next to the soil in a grassy area (as a lawn)
The layer of dead stems that may build up beneath grasses and groundcovers resulting in reduced water and nutrient penetration.
a roof covering of straw, reeds, or other vegetable material, held in place by stones, ropes, or poles, or interspersed with layers or mud
Lawn thatch is the layer of dead turf grass tissue between the green vegetation and the soil surface that must be removed (a process known as dethatching) to maintain lawn health. Lawn thatch is derived from stems, leaves, stolons, rhizomes and roots.
The layer of dead stems that builds up under many lawn grasses. Thatch should be removed periodically to promote better water and nutrient penetration into the soil.
layers of old, non-decomposed grass clippings and roots at the soil surface of lawns.
A layer of organic matter that begins to grow between the base of a plant and the soil. Usually discussed as a problem with lawns as dead roots and stems accumulate. Proponents of the organic philosophy say that in an organic program where soil has achieved a healthy balance, microorganisms are present to feed on mulched grass clippings and prevent thatch. However, if long grass (generally meaning growth of more than a week) is cut and mulched, there may be an excess of clippings which is too great for the existing population of microbes to handle in a timely way. Use your own judgement in determining how much is too much, then remove excess clippings from the yard and put them into the compost bin. Clippings of any length that are wet or matted should be removed from the lawn and placed in the compost bin.
Dead grass plant parts (such as roots, stems, and shoots) that have accumulated above the soil surface of a lawn.
A layer of organic material between the crown of the plant and the true soil surface
hair resembling thatched roofing material
plant stalks used as roofing material
a house roof made with a plant material (as straw)
cover with thatch; "thatch the roofs"
Undecomposed plant material that accumulates at the base of lawn grass.
An intermingled organic layer of dead and living shoots, stems, and roots that develops between the zone or green vegetation and the soil surface.
a brown, spongy material consisting of dead grass stems and roots that may build up in a lawn
A matlike buildup of grass roots and stems (but not of grass blade clippings) that if too thick can inhibit healthy growth.
a roof covering of straw, reeds, or even living grass. In modern homes, most thatching is only decorative, simulated with shingles.
A layer of dead grass that builds up between soil level and the blades of the grass. It keeps air, water, and fertilizer from reaching the soil below.
The dead tops of clovers, grasses, and wildflowers.
A layer of plant debris that accumulates between the soil and the grass blades, and prevents the flow of moisture, air and nutrients to the grass roots.
A tightly intermingled layer of dead and decaying roots, stolons, shoots and stems that develops between the green vegetation and soil surface.
an intertwined layer of dead and living roots, stems and blades of grass plants. It holds water, pesticides and fertilizer like a sponge, preventing them from reaching the roots.
Straw, reeds, or other plant material used for roofing.
An organic layer that has living and dead matter mixed together within it. A thatch layer is one that has developed between the soil and turf surface.
