Do all the fruit drop?

Can you be more specific about the size of the fruit that drop?

temps have generally remained between 55* and 73* -- Was 55 the overnight low, or the daytime high on a cold day?

I can only guess about your fruit dropping. With the cool temps & all the rain the plants probably just aren't ready to produce fruit yet.

One thing I'm fairly certain of...with 7+ inches of rain in 1 month and you watering on top of that the roots are probably drenched.

it is mostly likely due to the flowers in question not being properly pollinated.

hi, thanks for all your help so far.

in the month of june the lowes night time temperature was 46* on the first (my plants were covered) ever since then night time low temperatures have remained in the low 60's occasionally dropping to 55*

daytime high temperatures have been in the low 70's or upper 60's.

the last time I watered my plant was in May this month the 7+" of rain have more then taken care of the plants watering needs. however since the soil in the raised bed is well drain it is only moist not soggy.

the fruit are very tiny when they drop maybe 1/2 CM in diamater basicly one blossom setsand then the fruit drops another blossom sets and the fruit drops again etc...... The plant has not set any fruit that havee not dropped.

My other plants are well behind the sweet 100 so they don't have blooms yet .

I think that the flowers are getting pollinated since there is most certainly a very small fruit that is set before it falls off. there have been a fw blossoms that did not get pollinated and droped but they didn't form baby fruit.

thanks,

What you may be seeing isn't really a tiny tomato that has set but just the ovary of the bloom which has a similar but much smaller appearance.

then the stem holding the fruit on to the bloosom truss yellows and the fruit drops off.

That describes classic blossom drop. It can be due to lack of or inadequate pollination or from other stress - in this case perhaps soil that is too wet. Constantly "moist" is still too wet. ;) The plants normal response to stress is to drop blooms and even fruit.

Just be patient until the weather cooperates and allows the soil to dry out so the roots can develop sufficiently to support fruit set.
