How about growing tomatoes and chili plants in Costa Del Sol, Spain during wintertime ? I already have plants that have been growing since may.
The average temperature for December in the Costa del Sol is 12 degrees Celsius, although temperature lows can drop to a rather chilly 8 degrees and in january the highest is est. 15 degrees Celsius. Only five hours of sunshine per day are estimated in the run-up to Christmas.
Would my plants just grow slow, die or simply just grow as normal ?

Hi, as long as the temperature doesn't fall below 50f or above 80f, there's no reason you can't grow tomatoes in winter, they will take longer to produce fruit, as there's less light, just give them as much light and air as possible, Derek.

Sounds great. What about Chilis and peperfruits ?

Hi, if it's warm enough for tomatoes, chillies and peppers should be fine, Derek.

So conclusion is that vegetables don't know what time it is... :)

Hi, they can't read either :-) Derek.

I would look for a south or west facing wall, to give them extra fruit-ripening warmth. Otherwise, it should be the same as summer!

I don't think the problem is how cold it gets, but wind chill. I know my plants have taken a beating from the wind. Commercial growers use the cheap plastic cold greenhouse tunnels for protection rather than a lot of added warmth, around here.

True, Wylie! In any place with "Costa" in the name, wind is likely to be a factor, too.

I have similar temperatures in the Azores, and while some may survive, most die. You can grow brassicas in the winter, and there are no white flies to bother them. Potatoes will also grow.
