Commercial products are marketed describing the percentage of light reduction. [1] In hot weather, plastic covers need to be vented to prevent heat-buildup or too much moisture under the cover, and may have built in vent holes. Fleece material is self-venting and will allow water and rain to penetrate the cover. [2]
Except for some parasitic plants, all land plants need sunlight to survive. [1] However, in general, more sunlight does not always make it easier for plants to survive. In direct sunlight, plants face desiccation and exposure to UV rays, and must expend energy producing pigments to block UV light, and waxy coatings to prevent water loss.
Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. [citation needed] Breathability or moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m 2 /d), [2 ...
An early light frost can wipe out your garden harvest for the season. When a light frost is expected, water your garden to wet the plants. When water freezes it produces heat.
Many hellebores (Helleborus spp.) have thick green foliage that tends to last all year.The plant's bright flower colors, such as pink, yellow, or white, will add a much-needed pop of color to the ...
Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form classification system. [ 2 ] [ 3 ] Storage organs often, but not always, act as perennating organs which enable plants to survive adverse conditions (such as cold, excessive heat, lack of light or drought).
By elongating the petiole sideways, the plant repositions its leaves away from shading plants to absorb more red light, though there is a trade off in leaf size. The leaves can also bend upwards towards potential light sources as a result of higher growth on the underside of the petiole than the top, a process called hyponasty. [ 9 ]
