Tomatoes and night time temperature

[treepixie]

According to our local weather forecast the night time temps this week could be as low as 6c.

My toms are being grown outdoors will they be ok or should I cover them.

What a wonderful summer we are having!!

Wouldn't do any harm to cover them, but think about your own microclimate. If they up against a wall or fence they'll be warmer. Out in the middle of an exposed allotment site would be more of a problem!

as low as 6c? Should that not read as high as?

I find covering tomatoes is a bit of a two-edged sword. Tomatoes will survive low temperatures at night as long as it is not frosty, but throwing fleece over them can increase the humidity significantly. The last time I covered outdoor tomatoes with fleece they developed blight straight afterwards. This could have been a coincidence, but it was enough to stop me from doing it again.

Following on from the above...it's to be around 7 degrees tonight. Will my toms be ok in the blowaway? They have been out for a couple of nights now.

Mine have been out since the start of May with temps down to about 5C and it never bothered them at all.

When i first put them out i covered them with a sheet of newspaper overnight and removed it first thing in the morning.

Clever tom plants, eh Scoot, a bit of light bedtime reading, perhaps ......

One of them was a page 3 out the sun (it actually was). That might have helped.

I have tomatoes in a hanging basket out side now Jay they have been uncovered overnight for the last five days and they are ok, no discoloured leaves and starting to form flowers, I will cover them if the forecast is to be 4c or below but if they were in a poly shelter I would just shut the door

I've had some of mine out in the greenhouse for a while and they seem fine. Its been down as low as about 3 outside. Tomatoes will show you if they are cold - they turn a purplish colour and look sad, but even then they can recover as long as it isn't freezing. Its not ideal though.

My outdoor plants are on my hardening-off table. I think I'll bring them in to the greenhouse the next 2 nights because it's supposed to be quite nippy.
