Here’s what garden and patio plants you can save for next spring. As the temperatures start to drop and sweater weather arrives, you may start to look sadly at your beautiful, lush garden plants.
Likewise, winter temperatures can sometimes drop below the averages used to delineate winter hardiness zones, making it necessary to cover plants even in areas where plants are typically quite hardy.
Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bedding plants which are sown in heat in winter or early spring, and planted outside after all danger of frost has passed.
It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F (−1.1 to 4.4 °C). Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale.
Deciduous plants lose their leaves; evergreens curtail all new growth. Going through an "eternal summer" and the resultant automatic dormancy is stressful to the plant and usually fatal. The fatality rate increases to 100% if the plant does not receive the necessary period of cold temperatures required to break the dormancy.
David Mizejewski, a naturalist with the National Wildlife Federation, said removing leaves from your yard or garden deprives the area of nutrients while simultaneously destroying a wildlife habitat.
Trees may snap as they are dormant and fragile during winter weather. Pine trees are also victims of ice storms as their needles will catch the ice, but not be able to support the weight. In February 1994, a severe ice storm caused over $1 billion in damage in the Southern United States, primarily in Mississippi, Tennessee, Alabama, and Western ...
Map of average growing season length from "Geography of Ohio," 1923. A season is a division of the year marked by changes in weather, ecology, and the amount of daylight. The growing season is that portion of the year in which local conditions (i.e. rainfall, temperature, daylight) permit normal plant growth.
