Night time temperatures: when is it time to take the fleece off?

The forecast here for NW London is for another couple of cool nights on Monday and Tuesday (4C predicted), after which minimum night-time temperatures are predicted to rise steadily to 10C by next weekend.

Should 6C or 8C be the trigger to remove the fleece from the garden?

I think it is more about cold winds than low temperatures and we shall be removing covers from Tuesday, then progressively all week.
Spring is unfolding nicely and yes, the weather looks warm from next Thursday or so!

Indeed – I couldn’t have organised the warmth to arrive better timed for my February tomato sowings, which are now ready to be put into final pots and will live outdoors from Wednesday (they will go in the garage Tuesday night).

Sicilian radish (from Real Seeds) germinated absolutely beautifully under a fleece and even the recalcitrant Lisbon White spring onions have shown a few crook heads now, although I suspect I will ditch those rows and replace them with the Ishikura modules, which have germinated quite brilliantly indoors in soil blocks.
