Hi i set early potatoes in grow bag in early march in greenhouse and the stalks are all collapsed over night. Is this a bit early and they never flowered either. ????

[Gautama]

Sounds early. Was it cold last night, inverted greenhouse effect and all that? Choose one plant and dig it up. It there are reasonable sized potatoes there you're laughing. Otherwise it's something else.

Yvonne I agree with Guatama but I would dig in from the side low down to preserve the plant. If it has not flowered and has collapsed has it being getting enough WATERl It is odd for the stalks to collapse overnight and without flowering. This could be (but I sincerely hope not) BLIGHT.

It,s not Blight as far as i know, with Blight the leaves go brown very quickly, i mean within a couple of days, but do not collapse first, are thay getting enough water or did they get overheated. Post a picture if you can.

more likely cause is shortage of water, they will recover if given a good flooding.

Hi Yvonnehouli,

I had the same problem the first time I grew potatoes in the grow bags. They need a little more water that spuds in the ground. Do as Michael Brennock suggests and give them a good watering and they will recover. Also watch out that there are no green potaotes at the top of the bag, if there are just cover them up as you would if they were in the ground, you would earth them up.

Don't give up on them yet!!

You might also have overwatered them, that happened to me a few weeks ago, they do recover.

[yvonnehouli]

ya the lack of water could be possible as i was away for few days and might have forgot to water them when i got back.
