Sorry about your potatoes! Just wanted to say, it is fine to compost blighted plants, as the blight spores need a living plant to survive and will not survive in compost. (Any affected tubers probably best hot composted for this reason). It’s of course fine if you choose to burn them, but it is not generally necessary as blight is not soil borne in the UK (it can be in other parts of the world though, as you say).
The Allotment Kitchen Garden that’s fantastic information! Thank you!!
Self Sufficient Hub there was a very in depth article in the RHS magazine a couple of years ago - it might be possible to dig it up if you are interested. It did talk about blight being soilborne, but as far as I understand it there’s no evidence of this in the UK so far.
I tried a blight resistant main potato variety last year (we didn’t get blight until much later in the year though so couldn’t test this!) and this year I grew the same from homesaved last years potatoes, but due to the dry summer the tops have gone over weeks ago - will be harvesting them soon. It’s the third year in a row that I get more slug damage on main potatoes than blight - but I’m in the driest part of the country!
I find second earlies like Casablanca do really well as they are ready way before blight starts, and they get quite large too (though texture is not quite right for jackets, as I just found out!)
All my potatoes are no dig! 👍
The Allotment Kitchen Garden thank you!!
It’s something we really need to get to grips with as we rely so heavily on our potato crops.
Self Sufficient Hub I know what you mean - I don’t have enough growing/storage space for being self sufficient in potatoes so I am exploring other root veg that can just be left in the ground until needed (my husband and two kids love their potatoes but are not so hot on other roots though!)
I also find potatoes take a lot of mulch input, which is another limitation in my particular situation (even though I don’t “Earth”up)
I prefer growing potatoes in containers, even though they are slightly less productive and need more watering than in the ground, but I can reuse the compost after the harvest (I use my own rough compost for this). I’m very slowly growing my collection of recycled/reused containers for this purpose!
The Allotment Kitchen Garden I have the problem solved ! czcams.com/video/nDeVuVtYtoI/video.html
Dear Carl, Hello there. Catching up on the old videos. Great data on the potato blight. Thanks for sharing.
Hope all is well with you and the Family?
Best, Alex - NetZero Homestead
That’s tough Carl - really sorry. We are currently chitting six different varieties of potato and have such high hopes...I know how I will feel if our crop fails or doesn’t do as well as we expect. Thanks for sharing though. It is of real benefit to understand and see not just the highs but also the lows of trying to be as self sufficient as possible. Fingers crossed it’s the only setback you have with the rest of your harvest. Cheers Deb and Geoff.
Geoff and Deb Shipton thank you so much 😊
Problem solved! Free potatoes! Gleaning crops for free

Thank you for sharing your wonderful video
You’re welcome Teresa, thank you for your lovely comment 😊👍
Hard lines mate, at least you got a video and some potatoes out of it 👍 my next door plot has potato blight, mine have one or two brown spots on a few leaves so just going to chop my tops off and leave in the ground for a few weeks to harden the skins (I think I'll get away with that) don't think they're too big though
Thanks.
Yes it’s a really bad year for blight, I even lost all my indoor tomatoes to it!!
Gutted for you mate but thanks for sharing! Keep positive as there's always something else to take its place and harvest at a later date.
Matt Seldon thank you mate ❤️
I think I may have a solution which is super exciting but that will be the subject of another video (hopefully) in a few days.
I don’t want to mention it yet so as not to jinx it lol
Here’s my solution! Free potatoes! Gleaning crops for free

@@SelfSufficientHub Amazing idea! Wish I had the confidence to do something like this. How many did you manage to salvage afterwards?
Matt Seldon I got half a sack in about 20 minutes but was in a bit of a rush, am going back Saturday morning with my kids and will collect more 😊
I know excactly how you feel right now but seens this farming/planting is not just a thing and kind of spiritual if imay say, it having hope to harvest the potatoes. Something you've added your hope in and giving love daily and now reeping quite the opposite of hope. The lesson is that plants need love care and maintainance every day even if you will reep them in 3 months. Coz this deasise only takes a day or two to spread and you were there 3 days ago.... I know you are going to plant them againnow with more experience because it it is in your hearts. Take care farmer
Blight survives on live tubers, so make sure you remove any volunteers that pop up - a good reason to use crop rotation. Thinking "oh good some free potatoes" could cost you dear if they infect your entire crop.
Good advice, thanks 🙏
There is no need to burn blight-affected leaves as blight only thrives on living tissue. It is destroyed by composting or digging into the soil. It survives the winter on living plants and one of the biggest spreaders of the disease is the volunteer potatoes left in the ground from a previous harvest.
Hope this helps, Steve
Thanks Steve 😊👍
Frost. hmmm. well that makes it much more convenient for me in my crop rotation. Now I am having a hard time finding evidence for this. If it were true it would make my garden much easier to plant. I live in zone 3 so my frost is 8 months and my winters are as cold as -40 at times.
why cut when plants are coming up, have you sprayed with Aspirin to help protect naturally
@4:00 *living in Canada with only 88 day grow season and -30c for 8-9 months of the year, find out about potato blight after planting all my spuds and worried. Hear about frost killing blight, laugh, never worry about blight* Lol
Hi. I’ve just got blight on greenery now so if I cut off all above ground & potatoes seem okay below can I leave the rest of the potatoes under ground until I need them or is it a necessity to harvest them all together now even if they didn’t get affected?
I have been growing my potato plants for about. 2-1/2 to 3 months. I recently found little brown spots of the leaves. How do I know if this is Blight or just the plant dying?
what about copper fungicide? I use that on my tomato plants when they blight. That's what we do in New England.
I have heard of that but it’s not something I’m particularly familiar with
Spraying with baking soda , natural soap and vegetable oil works for me , spray once a week or two , never had a problem
Thanks 😊👍
do i mix all three in the same bottle?
Does it help against the trump cult virus as well
I use this too .... on many different veggies and fruits in my garden.
@@ben1000033Yes, look up diy fungal sprays and you will find tutorials 😊 (it also works to smother aphids).
Interesting video. Not sure about bonfire tho!
Thanks 😊👍
bro ,i grew the potaotes and in a month a part of the plant top wilted ,if you see this what might be the cause of it?
It could be a lack of water?
Was there any discolouration?
@@SelfSufficientHub no it just turned all black, on the topmost part of one of the shoot. I am damn sure it's not because of lack of water.
@@niveds6907 does it look like the blight in the video?
@@SelfSufficientHub can I have your Instagram link sir ,I can share the photo if you are not busy...?
It's nothing much but only a few potatoes in a big pot ,but those few are enough for me show my resolution , so I am caring too much 😄 I guess you can understand
I already have tomato blight. I already have the spores, are my potatoes going to all die then?
Not necessarily, make sure you dispose of the infected foliage to prevent spreading.
Do you see signs of blight on your potato plants?
@@SelfSufficientHub I saw the tiniest black spots. I removed those leaves.
@@eatme9970 I would earth up and cross my fingers but I’m not an expert 🤞😬
Cut the tops off
👍😊
