If you come for a summer farm tour at Johnston’s Cranberry Marsh in Bala, Muskoka, Ontario, you’ll discover how we ‘bloom and grow.’ Cranberries blossom in July and, by August the berries have formed. It’s now near the end of August, and we have lots of green berries on the marsh. The development of cranberries starts in June with the ‘hook’ stage. These tight flower buds start to open, progressing through partial bloom to full bloom and then into fruit set. (For more information on blossoms, click here.)
Another interesting development in August is the formation of the bud that carries the potential for next year’s crop. This bud sets in mid-August at the tip of the cranberry upright. From now until harvest, we’re managing two crops. After that, we have to manage the vines carefully through the winter to ensure that potential survives.
It looks like a good crop this year – we’re counting the days to harvest!
