Potato Failure..

AndyRVTR · « **on:** May 19, 2024, 12:35 »

I sowed my maincrop potatoes in one of the raised beds on 30th March, varieties were Mozart, Maris Piper and King Edward. All the seeds were chitted and planted using exactly the same method, however, the Maris Piper & Mozart have totally failed to grow, I mean not even broken the surface! The King Edward were my own saved seeds from last year and they are absolutely thriving, unfortunately, after digging a few of the others out, the chits are the same size as when they were planted. The MP & M were bought from the supermarket, but saying that, I bought MP from the same supermarket last year and they grew ok?

So the question I was once asked by a farmer who is one of our patients.... why are you planting main's so early when you are going to store them?
I was like you sowing in March.
I now follow our local farmers. Mains go in first weekend of May, my earlys 2nd weekend of April.
Done this about 4 years now and always get very good crops, others on site are moaning coz they have lost a good few due to more than average raInfall. They will not learn!

That's a great point re storage Aidy, this year however, mrs R and myself arent storing any as we're not eating potatoes (keto lifestyle).
I'm just growing them for family to use as and when they're ready, I just don't understand why half grew and half didn't, could they have been treated with something to prevent them growing as normal?

A fair amount of fruit & veg gets growth suppressant but I didn't expect spuds did given the state a lot are when I get round to eating them. Get to the supermarket and buy some organic ones.

Unless they are certified seed potatoes, you really shouldn't buy potatoes from the supermarket for planting. You have no way of knowing what viruses they may be carrying.

That's interesting Aidy. I have always followed the advice given by the late Joe Maiden, who used to have a radio show on Radio Leeds, and whose book Grow with Joe is an excellent one. He recommended planting all types of potatoes at the same time, 1st earlies, 2nd earlies, early maincrop, maincrop and salad. His rationale was that early potatoes take approximately 12 weeks, second earlies 16 weeks, early maincrop take until August and maincrop until September.
I follow this method, usually planting mid April here in Yorkshire and it works well for me.

I agree with hasbeans that your supermarket potatoes have probably been treated with a growth inhibitor. I also agree with Yorkie that it's best to get certified seed potatoes, especially if you are growing on an allotment where disease can spread to other plots.

We have a chap from Ireland on site, his way is... "in with Paddy, out with Billy"
So 17th March he was on sowing them, not long after he was F ing and Jeffing coz they were sat in water for days, he has lost at least half his crop!
Our last frost date is around end of April now so this why I always hang on.
You find the best way that works for you in your area.
Good luck hope you get a good crop.

Some supermarket potatoes are treated with growth inhibitor, some not. Very hit & miss & won't save you money in the long run. Buying good quality seed potatoes is more reliable, safer regards viruses & keeps the seed merchants in business for next year.

Regards when to plant earlies and main crops- they don't go in early & late, they're faster or slower at growing & are ready early or late if planted at the same time!
Same goes for other early varieties such as peas. You can sow "early" peas late in the season & get a quick crop before winter because "early" just tells you how short a time it will be from sowing to harvest.

My Grandad always planted his spuds on Good Friday, whenever it fell.
I plant mine after the last lamb is born (also very variable) just because I have time then.
The weather plays such a huge part that they always seem ready about the same time whatever I do!

So did mine!

Did you ever know why that date? My granddad worked in the iron ore mines, and I guessed it might be something to do with it not being Sunday, but never knew for sure.

Sorry, he never said, but I think it was quite common.

I'd guess it has a lot to do with people not keeping track of time & dates except by way of the Church calendar. The spuds is the one we remember but there were others.
Not all Church dates now but people here still put the rams with the ewes on Bonfire Night & bring them back in on Christmas Eve. You monitor your hay by having half left by Candlemass (Feb). Lambing starts April Fools day.
If you didn't read & write maybe you at least always knew when Good Friday was?

I just grow first or second earlies and put them in when the ground is warm enough, checking from the equinox. It was warm enough by the second week of march thanks to the mild winter I suppose (8.5c recorded 4 inches down), I put them in on the 23rd. We could potentially get frosts into may and I just mulch the shoots and cover with cardboard and cloche if frost threatens, which it did this year end of April. Last year we had a -3c that killed the shoots end of April as I couldn't get out to cover them. It did put them back a few weeks

AndyRVTR · « **Reply #12 on:** May 22, 2024, 07:49 »

I've always put them in in or very close to 'Good Friday', only because my brother and Dad did. They used to tell me that it was because 'Good Friday' was a day they could remember easily rather than a 'date'!
The only reason I used supermarket potatoes this year is because my local Wilkos closed down and local garden centres were charging an arm and a leg for minimum 2kg bags.
That and the fact I'm growing in raised beds in my own garden, so no chance of contamination anywhere else and as space is limited, I only needed a few potatoes as seed, so cost was also a main factor!

My dad and grandad planted potatoes good Friday Easter Monday as it was labour intensive compared to planting out most things.
And due to them working full time they knew that this was probably the only opportunity they would get to devote the time required.
