When to sow tomatoes in propagator

hahaha     was wondering that myself yesturday   lol  so i just this min done a few to try   i know its too early  but couldnt resist it   nothing ventured nothing gaind  try a few   gl.

I will be starting some soon, but they are destined for a heated greenhouse where I can maintain a minimum overnight temperature of 10^o C.

Hi Barlume,

As others have indicated, it depends where you plan to grow the plants. I grow them in an unheated greenhouse and outdoors, so it's still way to early for me to plant.  I usually sow my seeds, like you, in an unheated propagator on a window sill, and I start them off in late March or early April. That gives them plenty of time to grow and be potted on, without becoming too leggy,  before I plant them in their final position towards the end of May.

Good luck!

mid March for me.  To go out into an unheated greenhouse at end of April or later, depending on the weather.  Even so, most years I have an anxious few days when caught by a cold snap.  I have paraffin heaters, but they don't do much because my greenhouse isn't lined with polythene or bubble wrap.
