Tomatoes in Greenhouse

pauldreed

Has anyone planted their tomatoes out in a unheated greenhouse yet??
Mine are getting too big for the propogator, but unsure if it's too early and cold to plant them in the greenhouse.

Mine have been out for a couple of weeks and are growing on nicely

I see that you are in Southern England where it's a bit warmer, I'm in South Yorkshire, but if yours have been OK for the past couple of weeks maybe it's OK now here too.

Paul i`m in South Yorks too and mine have been out for a few days now, my greenhouse is unheated too.

If it helps the best investment for me (after many night time walks to rescue plants) is a min-max thermometer with a hygrometer and a memory. Keep it in the greenhouse for a few days to see what the temperatures are doing.

Mine have been in the greenhouse for 2-3 weeks and are doing ok.

I have already done that, and the temp drops hasn't dropped much below 8 deg C for the past 10 nights or so, but I don't know what temp the tomatoes need to grow, without a check to their health. (it's the first year I've grown them!).
They are looking really healthy at the moment, and will be gutted if they fall over and die!!

Sunnyday - if yours are thriving, then I'm tempted to give it a go.

Just keep an eye on the overnight weather forecast and cover them up with some agricultural fleece if the temp is likely to drop down to 2/3 degrees. Newspaper will do at a pinch.

They are fine, i`m just keeping an eye on the weather forecast just in case though.

They are only about 2" high but seem ok. My dad still has his on the windowsill inside the house (he has no central heating) and they are really strong plants so he will be putting them out tomorrow.

Pauldreed - working from memory, tomatoes need 50F to maintain growth - but they won't shrivel and die if it gets a bit below that.

Personally, I think misskool has it right - keep a check on your maximum/minimum temperatures.

My tomatoes (and peppers etc etc) are in a cool greenhouse in the SE of England. I won't switch the heat on unless it gets below 40F. If I didn't have heating, would still take the chance and resort to fleece if we hit a sudden cold spell (always possible in this country!).

By coincidence, I have just found an article in a weekend magazine written by Monty Don (good to see he's back writing!) in which he claims the minimum night temperature for tommies should be 10 deg C, otherwise they'll get a chill...

Which is, yes 50F!

I think that I'll take the plunge and plant them out, but I'll get some fleece first as a safeguard.

Thanks for the help.

I know I should be putting mine out soon but I feel really protective of them and don't want them dying on me. Think I will move them out and plant some more seedlings up in the space I will make inside the house so all my seedlings get the best start.
