Row covers can reduce the drying effect of wind, and can provide a small amount of warming in a similar way to unheated cold frames, greenhouses and polytunnels, creating a microclimate for the plants. The first commercial-scale use of polyethylene row covers in the US was in the 1950s, and by the 1980s their use was widespread. [1]
Typically it is raised further above ground level than a normal cold frame, so that the plants can be seen better when in flower. They are often used for the cultivation of winter-growing bulbs which flower in the autumn or spring. The covers are used in winter to provide some protection from very bad weather, while allowing good ventilation.
Deciduous Shrubs and Small Trees: Some patio plants or trees that drop their leaves can be brought indoors for the winter. Place them in an area such as a unheated basement or garage.
The abundances of plant species are often measured by plant cover, which is the relative area covered by different plant species in a small plot. Plant cover is not biased by the size and distributions of individuals, and is an important and often measured characteristic of the composition of plant communities .
So many healthy, happy blooming plants were displayed. Vicki had over 40 entries. There were stunning colors and single and double blooms with ruffled edges on the blooms and foliages.
The cover material is vapour permeable to prevent unwanted condensation from destroying transparency and to discourage the growth of mildew, fungus and bacteria. However, bags have been patented for protecting the fruit, vegetables and small plants by Kollath and Huffman (2000). [ 22 ]
If you don’t have the time or funds to buy a cover before a deep freeze, Tuscaloosa Emergency Management Agency suggests a quick DIY method involving rags or t-shirts, plastic bags, and tape.
Transplanting seedlings from a plant nursery to the field is a more effective sowing technique. Aerial seeding has a low yield and require 25% to 50% more seeds than drilled seeding to achieve the same results. [4] Aerial seeding is also often used to plant cover crops. Some plants often seeded by this method are perennial rye (Timothy, Red ...
