Totally Tomatoes April update: Potting on

I have tomato seedlings dancing before my eyes: dozens of them now, all doing really well and getting bigger every day. The lovely thing about tomatoes is that once you’ve got them up, they are really vigorous plants and so rewarding to grow as there’s not a lot which can stop them.

Frozen greenhouses aren’t good for tomato seedlings

Except, perhaps, this. We had a ground frost this morning, so typical of the weather in early April when you can be lulled into a false sense of security by balmy, warm, sunny spring days then wake up to ice on the greenhouse windows.

The Primabella tomato seedlings indoors on the windowsill won’t have been affected by this, of course, and nor will the seedlings in the propagator which I’m keeping at 10°C (50°F). But I am trying to find a way to grow tomatoes without using energy-hungry propagators, so I’ve also got a number of seedlings in the greenhouse without any heating: and freezing is not a temperature they enjoy.
