I have a 17 ft green house and have got 25 tomato plants in a staggered row down one side. Are they too close together. Will I encourage blight by pacing them in so much. They are a mix of brandywine heritage tomatoes, Alisa Craig, and Shirley. I could move some of them outside against a south facing wall. I already have about 8 plants outside. The Alisa Craig and Shirley. I have never had blight before and would be gutted if I got it now.

IMO they're more likely to get blight if you put the outside. Trim off the bottom leaves so that more air circulates. -
If they are zig-zagged you should be ok but you will have to be vigilant with removing armpits & bottom leaves.sigpic“Gorillas are very intelligent, but they don't have to be as delicate as chimps -- they can just smash open the termite nest,”

Congestion inside us more likely to lead to botryis due to lack of air circulation
Some of us live in the past, always talking about back then. Some of us live in the future, always planning what we are going to do. And, then there are those, who neither look behind or ahead, but just enjoy the moment of right now.
Which one are you and is it how you want to be?Comment

>>> I've crammed a fair few into my GH ..... When they're still fairly small they look ok, but as they grow and fill-out, they soon get overwhelming >>>
I'm determined to stay on top of them tho - as almost all germinated I had far too many, really, gave a few away but had to compost some ..... it was heartbreaking ....
So, hoping with plenty of 'hacking' away at unnecessary bottom leaves, armpits- I might get away with it....

Bal! The secret behind it as all others have said is Good ventilation! As long as ya get good airflow, and also damp down the floor for good humidity, they'll be fine!

I thought that blight is spread by rain and associated splashes ?
If I'm wrong then my GH growing plans are all looking a bit wonky...sigpic

I've no idea how it's spread I have never had it before so don't know what to look for or the conditions that precipitate itDogs have masters, cats have slaves, and horses are just wonderfulComment

Yes, that's correct. It survives over winter on living plants or tubers and seeds, which then grow up and release spores into the air. The spores drift on the breeze and stick to wet leaves or are deposited by rain. When the weather is warm and humid, the blight fungus grows rapidly.Originally posted by Baldy View Post
The plants in the greenhouse should be pretty safe from blight as long as you keep water off the foliage and keep the air flowing, because any spores that find their way in can't grow and develop on dry leaves. It's only if everything gets too crowded the humidity goes up and the leaves become susceptible to blight or botrytis.Comment

Botrytis is far more likely in the Greenhouse than blight and like everything else more likely when you get overcrowded later in the season. The plants look fine at the moment IMHO just watch and trim as they growComment
