I have heard that it is inadvisable to grow cucumbers and tomatoes in close proximity and even not to grow in the same greenhouse. Why is this? Many thanks.

I have no problems in growing them in very close together in my greenhouse. Ideally, tomatoes like a dryer atmosphere than cucumbers, but most of us to not have two greenhouses!

Never had a problem apart from a glut of cucumbers, I wish I could find a way of spreading out the crop a bit. It doesn't matter how late or early I plant the seed they are a bit like buses all come at once. Mind you I suppose that applies to the tomatoes as well. Pickling them is never as nice as the fresh fruit.

Cucumbers and potatoes do not go together. You may be confused as pots and toms are from the same family. I have never had a problem with them being near to each other.

Sorry LPM, tomatoes are from Solanaceae (potatoes, chili and sweet peppers, aubergines etc)and Cucumbers are from Cucurbitaceae (melons squashes courgettes, marrows);
I've grown them together without a problem but there may be reasons why not to too!

Logissimo. I do not think i replied very well to the question. Cucumbers attract blight to potatoes that is why they do not grow well together. However the poster asked about tomatoes and cucumbers. I was suggesting the poster may have thought that as tomatoes and potatoes are from the same family that the same applied but it does not. I hope this reply is clearer.

No.

Thanks LPM, I follow that, and just hope they can settle thritr differences in our greenhouse!

I have grow cucumbers, tomatoes and peppers in the same GH for years without any problems.
How? Cucumbers are not affected by blight so why would they attract blight to potatoes?

Maybe as blight is an air borne disease the cucumber plant takes it in but is not affected but the potato is. Its like every living thing some have resistance that others do not. Like people some you encourage and others you dont. Some people live well side by side and others hate each other. Thats life as they say. I just find it interesting to read these facts after years of gardening without this knowledge.

Still quite curious as to your sources of info LPM;
I don't see any reason why cucumbers should attract blight to tomatoes since they do not suffer from blight (Phytophthora) but they do suffer from mildew which does not attack tomatoes.
Intriguing!
My problem is that I'm growing melons in the GH with tomatoes. All are very healthy and my melon plant are rampant, loads of flowers but all male, no signs of any melons though. Perhaps I've overdone the nitrogen plant feed.

Has LPM got in a bit of a muddle with cucumbers, potatoes and tomatoes? I should imagine loads and loads of us are growing cucumbers and tomatoes in the greenhouse together with no problems. And no blight - so far, fingers crossed. Incidentally, I've never had blight on peppers, either.

Cucumbers have their preferences as do tomatoes. In an ideal world we should grow them separately but life is not always ideal so we compromise.
And we get a decent crop of both.
As to melons?-I have a baby . And about time too,been `introducing` them for ages and the females just got bored and dropped off-but one is growing

To make it completely clear. There is no problem with growing cucumbers and tomatoes together as i have already stated twice. The problem is with cucumbers and potatoes and blight. The original poster was asking about a problem with cucumbers and tomatoes. The reason i pointed out the problem was because tomatoes and potatoes come from the same family but only potatoes have the blight problem if planted by cucumbers. I thought i had made myself clear but i obviously had not as several posters have read my reply completely wrong. A lesson for me to not give helpful information out as it just confuses people.

Don't be sad LPM!
My lovely wife is always telling me off for trying to be helpful, writing messages with loadsof typos and incomprehensible things in them. I try to read everything twice just to be sure and yet daft things seem to slip through all the same.
We do appreciate your advice and we can only read what is there in front of us, perhaps you were writing with an east end accent!?
I still however see no reason at all as to why cucumbers should cause potatoes to catch blight any more than carrots for example. Perhaps I am just being thick?
Link to this forum: Cucumbers and toms grown in same greenhouse
Logissimo
Your wife is right you should listen to her.
Maybe you would like to explain to me what an east end accent has to do with this. I thought you speak with an accent not write with one. You obviously have more understanding of it than i do. Maybe your lovely wife should tell you off for being rude.
I suggest you read your last message twice and think about apologising to people from the east end.You obviously are very familiar with the area to know so much about it. No wonder your wife has to bring you down to earth.

Oh dear,
I have upset you LPM. I'm sorry, is that enough? It is only meant to be a friendly debate and I have obviously touched a raw nerve; Clearly my wit has missed its mark on this occasion.
Let's stick to debating more interesting things like vegetables and diseases.
Sorry once again, I mean it.

The original question asked about cucumbers and tomatoes growing together and blight. There is no problem because they belong to completely different families and blight (Phytophthora infestans) does not affect Cucurbitae and if a blight spore was to land on the leaf it would fail to germinate and thus die. Only some members of the Solanacae and in particular potatoes and tomatoes are affected by blight.
However, introducing the point that cucumbers and potatoes should not be grown together because cucumbers attract blight although they are not affected is very misleading. If this was true then we would not be growing many plants together because of the risk that one of them might attract disease to the other. Many diseases are spread by air bore spores so in conditions suitable for disease development and spore production the atmosphere will be full of spores.
Plant pathogens are specific to certain plant species and often within a plant pathogen there are races specific to a particular variety or varieties.
<quote>...Maybe as blight is an air borne disease the cucumber plant takes it in but is not affected but the potato is.

I read some were that one difficulty in growing toms and cucumbers together was one liked a high humidity level but the other didn't.
Does the humidity level in a GH have a connection with blight in toms
Link to this forum: Cucumbers and toms grown in same greenhouse
Yes, toms prefer low humidity but cucumbers grow best with high humidity. Red spider mite will rapidly kill a cucumber plant if it is hot and dry. Various leaf moulds will affect tomatoes if the GH is too humid and water condenses on the leaves overnight.
I grow both together, but usually lose the cucumber to red spider mite halfway through the season. One year I kept trays of water beneath the plants and watered the path everyday, resulting in all of the tomatoes getting leaf-spot. The cucumbers did really well though!

Phew, thanks for getting us back onto the debate.
I can confirm the different requirements of this range of plants. Last year I tried toms, sweetpeppers, melons, cucumbers and aubergines in my new greenhouse.
First I was told not to grow melons with cucumbers or the melons would taste like cucumbers. So I replanted the cucumbers outside. Everything went well until the aubergines started getting speckling on the leaves. Yes spidermite; it wiped out the aubergines; Nothing else was affected. This year I'm growing aubergines outside and no problems so far.
Also surely there should be a degree of humidity for toms, wetting the path is recommended in hot weather to favour pollination oconditions
PS eeh bah gum, this was written with a Yorkshire accent.

Well, reading this thread has just brightened my day. A bit of healthy banter is good for us all.
I say throw caution to the wind and grow both together, I do and never have a problem.
Mine is a brummie\yorkshire accent, in case you hadn't realized lol x

I posted a simular question on here about 2 months ago after I was told by the local garden centre I bought mine from not to grow them in the same green house unless I could put a divider in between them because they need different temp's. I still put them together without a divider, as I only have small poly house & they are all doing well. Loads of tom's coming & already had 1 large cue & plenty more to follow.
