\u00a0That may depend on the variety planted, but we will have to wait and see what the final answer is later in spring.<\/p>\n<p><a href=\"https:\/\/site.extension.uga.edu\/climate\/files\/2017\/02\/peach-county-chill-hours-2017.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-9965\" src=\"https:\/\/site.extension.uga.edu\/climate\/files\/2017\/02\/peach-county-chill-hours-2017-300x204.jpg\" alt=\"\" width=\"396\" height=\"269\" srcset=\"https:\/\/site.extension.uga.edu\/climate\/files\/2017\/02\/peach-county-chill-hours-2017-300x204.jpg 300w, https:\/\/site.extension.uga.edu\/climate\/files\/2017\/02\/peach-county-chill-hours-2017-203x138.jpg 203w, https:\/\/site.extension.uga.edu\/climate\/files\/2017\/02\/peach-county-chill-hours-2017.jpg 703w\" sizes=\"auto, (max-width: 396px) 100vw, 396px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Because of this year&#8217;s warm weather throughout the winter months, the accumulated chill hours that we have seen this year are even lower than last year&#8217;s values, and is only about 50% of what we usually expect by this time of year. \u00a0If we use previous years of weather data to project the range of [&hellip;]<\/p>\n","protected":false},"author":58,"featured_media":9965,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[25,6,8],"tags":[],"class_list":["post-9964","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-fruit","category-sources-of-weather-and-climate-data","category-tools-for-climate-and-agriculture"],"_links":{"self":[{"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/posts\/9964","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/users\/58"}],"replies":[{"embeddable":true,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/comments?post=9964"}],"version-history":[{"count":5,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/posts\/9964\/revisions"}],"predecessor-version":[{"id":9976,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/posts\/9964\/revisions\/9976"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/media\/9965"}],"wp:attachment":[{"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/media?parent=9964"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/categories?post=9964"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/site.extension.uga.edu\/climate\/wp-json\/wp\/v2\/tags?post=9964"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
