Frost Damage in Saskatoon Bushes

POSTED IN For Growers ON 5/19/2016

Well, we had quite a chiller go through this past weekend, and some have seen frost damage. While saskatoon bushes are pretty harder throughout the winter, they are a bit more suseptable when they are in blossom. In Northern Michigan they have seen some signs of damage, though not as threatening as with some other crops.

Elsner_Duke_2013_CroppedDr. Erwin ‘Duke” Elsner, Small Fruit Educator with Michigan State University Extension recently helped us understand how to tell if your plant has frost damage, and what to do about it:

Frosted tender leaves will show darkened margins, almost black in color.  The injured tissue doesn’t grow or stretch as the rest of the leaf continues to grow, so the leaves look more crooked or crumpled the season continues.

Lightly frosted flowers just show some browning of the petals.  

Nothing needs to be done to these light frost injured plants. Under most circumstance they will continue to grow and produce this season.

Best wishes to all you growers and harvesters this season.  If you find that you have unusual damage due to cold temperatures, please let us know.
