Title: Potato plants falling over
Post by: whaleroad on July 21, 2021, 09:45
Hi. I planted some Cara potatoes at the start of May. They were doing fine and flowered a few weeks ago but now quite a few are falling over. I've tried hilling them but they really want to lie down.
Some of the lower leaves look like they are dying back but it doesn't look like disease and isn't spreading rapidly.
I'm in London, but I suppose it's been very hot everywhere this past week and the south-east wasn't exceptional. Could the heat be to blame?
I've cut down one plant as it was interfering with its neighbours. That means it's only had 11 weeks' growth, rather than the 21 recommended - will there be some half-size potatoes down there or does it not work like that? I'm leaving them in the ground for now as they're recently watered - is that the right thing to do?
Any idea why they're falling over though?
Thanks in advance.

Good afternoon whaleroad, could it be that your spuds are coming to the end of their alloted lifespan?
Cheers,   Tony. :D

All my spuds are the same. Slowly falling over and dying back.  Seems very early to me.  I expect my spuds this year are going to all be gold ball size or less!  :(

Here, it has been very dry this month and suspect they needed more watering than they got  ::)
I'm not expecting huge yields this year tbh  ::)

Thanks all - all my searches for info seem to support your theory, that they are maybe coming to the end of their natural life. It does seem very early but I am a total novice so what would I know!

I don't mind having some small potatoes now, hardly anything else is ready and I've got another bed full of Maris Pipers that are [touch wood] still perpendicular.

Should I cut the Caras down and leave them a couple of weeks, or just stop watering for a couple of weeks and dig up the whole plant?

Water thoroughly if you can, then just dig up a root as you need them. The heavy rain & wind toppled some of mine a few weeks ago

Mine are the same, Charlotte, we've had some and they've been really good.
Continuing to water is fine, but do you leave the foliage on?

Cross your fingers a plot neighbour said his were similar in the heat here in the south.
Fingers crossed the spuds might swell after the heavy rain forecast for the weekend HH

Well I dug up two of the worst affected plants - I got some decent-sized potatoes from them, just not very many (about 10 from two plants). The skins are thin, like new potatoes. I don't mind that, I suppose it just means I need to eat them soon?

Anyway, my first ever potatoes and I think they look rather nice.  :)
