    For the third year running, got the dreaded blight in my greenhouse! I have tried every thing to reduce the risk, just one thing left to try and that is to relocate the greenhouse to a different spot in the garden? I live in Wales, Swansea to be exact, and the summers are now damp and warm (perfect conditions for the blight) Anyone on this forum from my neck of the woods? if so, are you experiencing the same problem? I'm pulling my hair out. Again we had a good start to the season, plenty of sun then half way through, rain, rain and more rain!
    Brian. :( :( :(

    :scratch: Oh dear Brian that is terrible for you..... I am not that close to you, but not so far either... I have suffered with it over the years on & off & my answer is to empty my greenhouse of all it's plants, any that have it it I get rid of. Although in saying that I do know people who spray with Bordeaux mixture..... Sad I know but I feel I have to cut my losses & ditch mine & I then shut off my greenhouse & set off a fumigation bomb in there.. After thet has done it's work I then make up a solution of hot water with plenty of bleach & Armillatox in.. (You can use Jeyes fluid if you like) in the water & get a broom & slosh & rub every area of the frame with it..
    I do not have a solid floor in them so I then pour what is left all over it.. Go away for about 20mins & let it soak, then I get in there with the hose pipe & rinse everything off really well.. Leave it & all vents open to dry completely for at least 24hrs....
    :scratch: That is what I do & it works for me.. I have only had it a couple of times but not good I know.. I feel good ventilation helps allot.. I bought a couple of solar powered fans for the greenhouses & keep them in there now as well so my air circulation is good, I also put in extra slat vents & an extra window & it certainly seems to have knocked it on the head...... :dh: Well fingers crossed it has anyway.........!:wink:

    Brian; are you sure it's blight?

    I've used Bordeaux mixture within my greenhouse to stop the ravages of blight - it does work - although it doesn't cure blight it prevents it getting any worse, so providing you spray as soon as you see the first symptoms you'll be OK. Thats a better solution than discarding all your plants. Finally you could use a preventative spray if you are in an area where it is prevalent.

    Brian,as has been said, are you sure it`s blight? I look after a veg garden in the north of Cardiff and I have no problem, even though it`s been warm and humid.:thumb:

    Thanks for the reply John. Yes I'm sure it's blight, leaves have dark blotches and on the under side a silvery sort of colour leaves are limp, browning on the leaf stalk etc( I cut this away, and eventualy the whole leaf branch) I have sprayed with a solution made up of " Fruit and Vegetable Disease Control" from Bayer Garden which is slowing it down.
    Brian :(

    Sut mae Dai!
    The next leaf I cut away I will take a pic and post here, I dont think it can be anything else really (from the first signs it dont take long for it to spread, it goes like the clappers).
    Thanks for the reply
    Brian.

    Sorry to hear that Brian, yes that is blight by the sound of it.

    You have been unlicky to get it 3 years running and inside a greenhouse. I was amazed when I got blight in my greenhouse a couple of years ago, yet my neighbour growing tomatoes outside and only about 10 yards from my greenhouse escaped completely. :cnfs: I wondered at the time if the blight spores were in my water butt (I collect rain water off my shed roof).

    Surely keeping the foliage dry is the answer, only water around the base of the plants and I've removed some of the glass in my greenhouse in order to get the air flowing.
    I'm sure my outdoor plants will get it at some point, they always do these days, but I will spray with bordeaux at the first sign.

    Hi Pete, from previous in fections I keep the door and vent open at all times, change the border soil with compost, water the base only, and at the end and beginning of the growing season use the power spray (filled with jays fluid) and give the green house a good dousing. All this and I STILL get it!!!
    Thanks for the reply
    Brian

    Sorry to hear about your blight :(.

    We now tend to grow our toms outdoors in a sheltered position and seem to get better results. When we grew them at the bottom of our garden (exposed to fields) we were getting blight each year and the greenhouse sometimes got it later. We keep the greenhouse very well ventilated and this now seems to keep the blight away until we have been able to harvest most of the crop.

    The best results have been from our tomatoes we grow in a sheltered but well ventilated part of our patio. There is fence on three sides so the area gets the sun reflecting off the fence and keeping the plants dry. We, of course, only water from the bottom and have found that the toms ripen just as quickly as in the greenhouse. Blight only got to them just as they were ready to be pulled up anyway.

    [​IMG]


    So our formula now is:-
    outside for ventilation
    shelter for warmth and quick drying
    water from bottom.

    This wouldn't, of course, solve the problem of rain all summer.

    We still try growing them down the bottom of the garden and in the greenhouse as well :dh:

    ... but you do have Oscar, your secret weapon, to scare away the blight. :) What a handsome cat! He's obviously into beans as well as onions.

    I haven't grown tomatoes for years but I'm giving them a go (outdoors) this year. I've got lots of fruit, none of it anywhere near ripe, and I'm wondering whether anything will be ready for harvest before the monster blight strikes.:(

    Brian, we are only assuming that it`s tomatoes affected, is this correct? Let`s have some pics, are you sure it`s not Blackleg?:thumb:

    Don't worry Clare, they'll start ripening soon :gnthb: (Oscar told me :hehe:) k-l

    By the way, I just picked 120 garlic and put them on the table to dry, with the onions, and Oscar is fast asleep on the garlic :hehe:

    Hi Dai, I am only going on the symptoms that were diagnosed as blight the first year (a gardening friend came up and confirmed) as for black leg, I havent heard of this before (not surprising as I've not had a green house untill three years ago) I'm a novice when it comes to gardening so I dont know much any way! I will take some pics and post them on here. I must say, this site is such a help for me, so many people willing to help I find it so refreshing :cool:
    Oh and yes, just the toms.
    Brian
