I am growing Long Green Bush Marrow; Vegetable spaghetti and Butternut
squash. Does one need to remove the male flowers from these plants,
please?


If you remove the male flowers you will get no fruit, the female flowers
will remain unpollinated and the embryonic fruit underneath will simply
wither and drop off.
What made you ask the question?
