Winter Tomato Project

Allen Park, MI(Zone 6a)

I'm experimenting to see whether or not I can get some heirloom plants to produce fruit in the greenhouse.
We have a 1000W grow light to aid mother nature.

I have a variety of plants.

As for pollination I hung a fan from the ceiling blowing directly on the plants about 6 hours a day.

If anyone has any suggestions please let me know

First off, I say get them potted up in larger containers- those are in tiny cell packs, and are way overgrown!

Paul, use really deep pots for tomatoes - 3 gallon or bigger nursery pot for each plant would be good. They like to send their roots really deep! Tomatoes are originally tropical plants, and can last 2 or 3 years, but they get really woody and ungainly, and less productive.

I used to rescue tomato plants from my garden in Utah and keep them going on a sunny windowsill in the basement there all winter. If I could keep the right temperature, they would set fruit nicely. (gotta watch not to bring in bugs if you rescue from the garden, though) Keep the soapy water spray handy, I spray at least once a week to keep aphids and whiteflies at bay.

- Lots of water, and as much sun as possible.
- Night temperature is pretty critical for fruit set, between about 50 and 65 night time temps work best. 70 to 80's daytime is fine. They love heat.
- You can use a tiny paint brush to pollenate the flowers if your "wind" doesn't work. The fan will help you keep fungal diseases like powdery mildew at bay.

Here are 'Momotaro' tomatoes I grew from seed planted in September. Flowering and about to set fruit if it will only stay warm! Second pic are my Earth Boxes growing grape tomatoes, eggplant, peppers and two kinds of broccoli.

We have a automatic irrigation system, I have the heat set on 75 but on sunny days it gets to 85 or higher.

Thanks for the info

You might want to let it fall to 60 - 65 or so at night, Paul. If it's too warm at night the plants will stop setting fruit, too!

Down here in the summer that's when we know tomato season is over, when the nights get too warm and the tomatoes stop setting. Usually some time in May.
