What plants are you talking about?

I talking about tomato plants, Better Bush, Mr Stripey, Current Yellow. I thought I was in the tomato section, that's why I didn't say in my OP, sorry.

Oh, I didn't notice the topic heading. I suggest taking MR. Stripey and tossing it into the compost bin, it's a terrible tomato. I tried it twice and disgusting both times.
Tomato plants, both determinate (better bush) and indeterminate (Mr. icky and Current Yellow) will take 5 to 7 weeks to flower from the day they germinate based on cultivar even as short as a foot tall. Your Plants clock started ticking sometime in February so they had more than enough time to make babies (seed) and flower, and were tall enough.

Tomato roots grow over an inch a day so they may have an adequate root system by now to grow a tomato, but the tomato will always have priority for nutrients, followed by the roots with the plant last in line. Plant growth may slow down with hanging tomatoes if the root system is to small. If my indeterminate plants were to small I'd pick off the blossoms to let the plant grow bigger. The better bush I'd probably let the blossoms stay, I never mess with my determinate tomato plants and do remember some flowering early but never picked them off. I don't remember how the plants turned out because I grow 20 to 40 determinate plants each year for the last 20 years. I planted 16 indeterminate plants and 31 determinate plants today which I started April 9th indoors and are about 8"+ tall.

BTW, there are no male or female flowers on a tomato plant. Tomato flowers have both male and female reproductive parts and are self pollinating.

Thanks Kevin for that info. I've never had much luck with Mr. Stripey either although I have gotten a few sandwich sized ones over the years but that's about it. I've had the best luck with the Better Bush and this is the first time for Currant Yellows for me. I guess I'm getting mixed up on male/female flowers from reading up on growing pumpkins, watermelon, and cantaloupe.
