Guide To Gardening Zones

Being familiar with gardening zones can save the average gardener time and trouble. Gardening zones are a guide to the lowest mean temperature variants and estimated frost arrival times of various regions around the world. Gardening zone guides can help a gardener decide what to plant, how to plant it, and when to plant it.

Having a familiarity with the gardening zone you reside in, as well as the individual gardening needs of the varieties you intend to plant, can greatly increase your chances of raising a successful garden.

Gardening zones, sometimes called hardiness zones, are updated every year and keep a running tally of each region’s vital statistics. The lowest winter temperatures are averaged and each region is given a zone number. While relying on the planting advice of the gardening zones and regions, be aware that there are also criticisms with the zoning system.

The demarcation of regions into gardening zones does not take into consideration higher temperatures of that region. Regions with a more temperate winter climate but a hotter summer temperature could be categorized into the same gardening zone as an area that is temperate all year round.

Another factor not taken into consideration by the gardening zone placement is the accruement of snow. Regions with a heavier snowfall tend to have more blanketed ground insulation. Thicker ground insulation can lead to more temperate ground conditions and therefore a longer growing season.

Gardening zones do not record the amount of snowfall, so regions that receive heavy snowfall that lasts a long time on the ground can be placed in the same gardening zone as areas that receive no snowfall, or where snow initially falls but doesn’t linger on the ground.

Gardening zones are particularly effective in determining an average winter temperature. Low winter temperatures can be one of the major factors in the survival rate of plants. Because gardening zones are determined by several years’ worth of average winter temperatures, they are moderately reliable, but not infallible.

Summer temperatures can also be a factor for plant life survival, and winter temperatures can occasionally be unseasonable warm or cold. But gardening zone recommendations can serve as a good general indicator of the success rates of different plant varieties in a particular region.
