Since this post sort of brought it up. I figured I might as well ask. As it's my first go at growing tomatoes in a foreign land without mommy close by to hold my hand and ask for advice. :P Should the weather take a turn for the worse and go down to 0 degrees Celsius or thereabouts so we would get a possible frost night. Do you think that my little 'greenhouses' as seen in the image behind the cut would be enough to protect my tender little tomato plants. Or is it better not to risk it and take them inside if it looks like it might possibly go cold overnight? And since I'm on the silly newbie questions. This thing about always growing tomatoes and other plants like it that want it hot in black plastic pots (on the assumption that black soaks up the heat rather than reflect it and keeps their roots nice and warm), that I've picked up from somewhere - probably from mum or her father - as a child. Just an old wife's tale?
