I used heroic measures to save the one Japanese plum tree (Shiro) that had weathered winter lows of -12F by using tarps and heaters, etc. to protect the tree from a recent deep freeze. The bloom is near full now and being the lone hot spot in town is attracting heavy bee activity (>100 insects at a time). The only source of pollen for cross-pollination is a Methley that grows about 20 feet away. This tree was unprotected and only has about 2% of its normal number of flowers, and surely,given the temperature exposure, the ovaries of those flowers are dead. Still, the bloom attracts moderate bee activity (maybe 10 insects at a time). So this is all I have left of my crop - should I be looking for alternate sources of pollen (no easy task) or should these injured Methley flowers be expected to still provide viable pollen to cross-pollinate the Shiro. Tough question I know, any opinions?
