Cant grow pears? Losing pear blooms to frost? If you have a recurrent issue every spring where you lose all your blossoms to frost maybe your growing the wrong pear
" Description - # Colette Everbearing Pear Tree
Outstanding quality that keeps going. Broad for its kind, this shapely tree repeat-blooms and bears until hard freeze. First crops are of Bartlett size with superior quality, yellow skin, and a light pink blush. Smooth and aromatic, grit-free white flesh is excellent for fresh eating but also retains its flavor when canned. Subsequent fruit is set when other pollinators have finished blooming – a unique trait of its somewhat self-fertile nature. Originates from Illinois, introduced in 1953. Cold-hardy. Harvest mid- to late-September through hard freeze. Partially self-pollinating. Best pollinators: Bartlett or Beurre Bosc. " - Colette Everbearing Pear Tree - Stark Bro’s
Seems that a decade ago it was a good pear. Maybe things have changed. I recently saw a good review on one of my FB groups that the poster says it is self fertile…as they do not have any other pear trees.
