I have several heirlooms that blossom but are not setting fruit,,they are drying up and falling off..but my other toms are setting fruit..Celebrity, Homestead, Bhn 444,..i have looked up other forum replies in the past and I just can't understand why under the same weather conditions,,,low being upper 50-60 and and high being lower 80's..that the others are setting fruit and the heirlooms fail..they all get the same treatment. Everyday I go out and examine the garden..give the stalks a lil tap tap tap..it has been a lil bit windy so I figure that will help too,,..My Caspian pink is huge,,,and the Amish Paste as well..as others,,i read about using an electric toothbrush..to help pollination..does this actually work?

Finally why are the other toms doing so well and the heirlooms stubborn? I know that they are particular and usually picky about growing temps,,but I haven't even hit the heat of the summer here.

The weather here has been overcast in the morning and clears up to full sunshine by 10am..

Happy Gardening.
