Using historical climate data from NOAA, Plantmaps has created a new interactive map displaying average annual first frost dates for Iowa as well as major cities in Iowa which will assist gardeners and growers with frost protection:
First Frost Date Map for Iowa
The interactive first frost date map can assist gardeners and growers trying to decide when to plant seeds, when to plant a garden and what type of plant frost protection to use.
Plantmaps has created a new interactive Iowa Drought Conditions Map based on the Palmer Drought Index produced NOAA. A drought index is produced for each climate division in Iowa. Each climate division is assigned a drought level based on it’s current drought index value. If the region is suffering from drought conditions, the interactive drought conditions map reports the amount of rain needed to alleviate the drought. Other data that make up the Palmer drought index that are incorporated into the interactive maps are: Average Temperature, Average Precipitation, Upper and Lower Soil Moisture and a crop moisture index.
Interactive Iowa Drought Conditions Map
In addition to the interactive drought conditions map, plantmaps.com also has several other valuable tool for Iowa gardeners, farmers and environmentalists such as the interactive Iowa USDA hardiness zone map
, the interactive Heat Zones map
and the interactive Ecoregions map
Plant Maps has added a new interactive Iowa Plant and Tree Hardiness Zone Map based on the 1990 USDA Hardiness Zone Map. Iowa covers a wide range of growing zones and this new interactive map allows the user to zoom to the city and street level to determine the exact gardening zone. Hardiness zone (sometimes referred to as Growing Zones or Gardening Zones) are used by gardeners to determine the ability of a plant or tree to survive a minimum temperature in that zone.
Plant Maps also allows users to locate their gardening zone by entering a zipcode in the planting zone to zipcode search tool.
