It seems to me, living in CA this year is synonomous with slow tomato growth. Personally, I would not cut any tomato that was there, unless I was taking down the whole plant. I have a lot of slow growing baby greenies. My nights are still pretty cool, most the time around 50 now but have had a few really warm 75-80 days in a row. I can see an improvement in my worst (bacterial speck) plants putting out new green growth and blossoms. This is the first time I have ever planted so early 3-15, my last frost date, AND had such a string of cold Spring weather. I have never had bacterial speck before so I am just watching and waiting, while spraying with copper soap! Hopefully someone who knows more than me (just about anyone) will add their thoughts.

With no growth in 3 weeks then most likely what you are seeing is not a little tomato but the unfertilized ovule the base of the carpels of the bloom. See link below for pics.

I am having the same issue with my Goliath hybrid. Ten or so huge blossoms with no fruit. My other tomatoes have all set fruit, however it is not going to ripen in any sort of hurry with these cold nights. Today hit 90 and tomorrow 92 is the forecast but then back down to 80s and 50s at night all of next week. This is by far the coolest summer I have seen in 23 years living here. I would just give it some patience, they should explode when the time comes.

In my experience, if the blooms aren't pollinated then the plants will drop them (without your help) from the stems about a half inch or so above the blossom. If the tiny fruit isn't doing anything, then there isn't any energy from the plant going into making it grow. Maybe it will drop off later, but maybe it won't. Sometimes it does seem like there's a delay before they start sizing up, while sometimes there's just a delay in dropping off. Either way, it doesn't hurt to just wait and see.

Well, two weeks later (over a month total) and some of those spent blossoms are actually growing tomatoes! I'm so used to hybrids & cherry tomatoes that flower, fruit & grow. But, several of my heirloom tomatoes have these blossoms that dried up weeks ago & are just hanging out. Here's to hoping that they all produce tomatoes!

Good for you!!!! Always a dissapointment when they dont do what they are supposed to. Hope they all follow suit! Linda
