Remember–To bloom and produce fruit, tomatoes need 50 degrees.

That’s right, tomatoes like it hot. Well, at least warm. This means they will bloom and produce more fruit when the night-time temperature is at least 50 degrees.  You can accomplish this with a little trick.  Put  ‘Walls o’ Water’ around them from the first day you set the tender plants outside, and they will collect heat in their little water chambers (arranged in a teepee-shape when filled) then dispense it at night to the plants inside.  If you take care of your ‘Walls’, they will last for years.
