Zac from Berkeley, California was worried about his potato plants flopping over so I asked him to send in a picture. I thought maybe YOU and I could help him.
Here is what Zac had to say:
I have six 30 gallon plastic grow bags full of potato foliage and now flowers on some. After hilling them in as much as possible, I’m now staking the stakes to keep them upright.
This is the photo I took this morning. Not all of them have been staked (yet). But I’m on the alert if I have to do so. I’m figuring that they’ve reached their height potential now as flowering buds are starting to form on most.
I did some searching on the Internet and got mixed opinions about what’s going on with them. Some folks said not to worry about it since its the roots we care to eat. Others thought it would be best to prop them up to allow them to grow more! I just began staking them after a few of the larger stems snapped off!
Well Zac, I think your potato plants look great. But, I am worried your grow bags are not deep enough. If there was a way to set your grow bags in deeper ones, remove the old bags and add some more soil, you might get a larger crop of spuds. But otherwise I think you are right, your potatoes are nearing the end of their cycle.
