Fruit growers need to constantly assess the stage of development of their crops and the susceptibility to freeze injury. Unfortunately, spring freezes are almost a certainty in any given year. Picture Table of Fruit Freeze Damage Thresholds includes the same information and includes pictures. Tree Fruit Critical Temperatures is a table of common tree fruit with bud stage names and the critical temperature ranges that will cause between 10% and 90% injury to the flower buds, all on one page. Chop the candy bar into tiny pieces and freeze for at. Michigan State University Extension has two tables for the critical temperatures of tree fruit during development. Frozen Amys Minty candy pieces add bursts of minty flavor and texture to this thick and frosty shake. The stage of bud development determines how susceptible any given fruit crop is when freezes occur. Near bloom, the range between slight and severe damage is very small. As bloom nears, temperatures in the upper 20s can cause considerable harm to an early blooming species or variety and leave other fruit crops unaffected or with only slight damage. Early in development, at first green and green tip stages, temperatures need to drop into the teens or lower to cause significant bud damage. Amys Frosty Freeze « Back To Mifflinburg, PA 0. Early in development, there is often a wide range between the temperatures that cause little damage and those that cause severe damage. This range of damage coincides with the growth stages and fruit species and even the cultivar. As buds develop and begin to open, temperatures in the low 20s can cause harm to fruit buds and perhaps developing leaves. Early swollen buds can often withstand temperatures in the teens (degrees Fahrenheit) without any damage. ![]() As buds swell and development begins, the ability to withstand cold temperature changes with the growth stage. As we move into the warmer weather in March, April and May in Michigan, tree and small fruits lose their winter hardiness. ![]() Temperate fruits can tolerate very cold winter temperatures.
