Are there any tomato breeds that are more resistant than others
to cold weather? I am wondering if any of them could come close
to being perennial, even if their fruit were kind of small, or
That way they'd almost count as perennials.
if the frost does not see them off the blight will. as the winter gets cold
and more to the point damp. I have never had any survive through the winter
even in a green house. having said that the green house is not heated. may
be heat would make a difference, but would it be economic to have heat on
?. it would not for me so I have not done it. hope this helps you.

The three tomatoes I had in my greenhouse I planted last November in 3
gallon pots... I bought them in 4" pots.
They wintered just fine even with all the "damp" in the greenhouse!
They are now blooming and setting nicely. :-)
I opened the front screen door during the day when it was above freezing
to let the house dry out a bit and at night, I ran a single 75 watt
lightbulb in a clip lamp to heat it.
The greenhouses don't have to be kept really warm, just warm enough to
keep the inside temp above 32 degrees! They got down to maybe 40 at the
lowest even on the coldest nights.
My greenhouses are 8' x 8' x 7'.

There is no need to change the world. All we have to do is toilet train the
The Russian tomato varieties do better in cool weather. Look at the
Territorial Seeds website -- they sell a bunch of Russian varieties.
Also, if you live near the coast, composting seaweed right on your garden
beds will lower the temp that plants can survive by a few degrees. Or
buy kelp fertilizers. (If you can get actual seaweed, you don't need to
hose the salt water off it. Just layer it on your beds and let it rot or
dig it in, or mulch the beds in the fall with it.)
