if later fruiting flowers drop in large numbers, it is probably due
to insufficient pollination.

Control and comments
No action required
Adjust planting date
Frequent bee visits are needed for pollination. If bees do not visit your plants, hand pollination is possible using an artist's paint brush. Look for bees between 7 and 8 a.m. Avoid use of insecticides that will kill bees.
