Can feijoa's really take subzero temp of - 17 C/ 1.4 f . I am growing three varieties two of which are unknown and one jemini. All over the web there are statements that the plants handle such low temps, so my question is ..... do the plants start to have cold damage at this temp , or is this the temp on which the plant is killed to the ground ?? If the latter , can anyone shed some light on the stages of cold damage for feijoa for the leaves , young twigs , older wood etc. and on what temps have u all witnessed different cold damage stages . As usual thanks for any inputs !!☺
