I have some mint in a container that was growing fine.  It started to grow very rapidly and started taking over some other herbs in my bucket, so I cut it down.

Now, I have read somewhere that the brown spots could be overwatering, so I moved the bucket to a more sheltered area, but it seems to have got worse.

Any advice is welcome.

canwe see a photo of the mint Martin? Mint grows quickly and soon looks poor in a container. It needs a container to itself or it will swamp the rest

I suspect it could be rust. Mint aften becomes beraggled at this time of year. A photo as nitcutlet says would help diagnose the problem

Thanks for the replies, I shall get a picture up ASAP.
I hope its salvagable! If not, I suppose I can put it down to experiance.

It dies back in winter, you can repot some roots and all will be well

Righto, a picture

 Is there a way I can save mint over winter? I.e bringing it inside?

I'd cut that back Martin, it's over for this year. A bit more room for expansion next year as well, a deeper pot for just the mint.


You could try potting up some root and bringing it indoors, nothing to lose. I've never done that so I don't know it it works. Leave some in a pot outside for next year though, it will be back

I like the refections on that container. Is it stainless steel?

Thanks Nutcutlet.

If I cut it back and re-pot it at the same time would that be ok?

Yes it's stainless

You can force mint by putting some of the root in a container and keeping it in a gentle heat indoors or in a greenhouse. It soon shoots and you should be able to keep it going all winter. Lay a length of root in a seed-tray, cover with compost, keep moist and warm. I think your problem is over crowding coupled with it being the end of the season. However, if it is rust, chuck it away and scrounge some more to grow for next year.

The old way of growing mint was to grow it in an old sink, which was then buried. It is deep and big enough to get a good amount of growth, without letting it take over the whole herb patch, which it will do given half a chance.

Yes.Martin, take the top off, split it up, tear it apart, do as Adam suggests with some of it and leave some outside in a pot for next year. You can be rough with it, all those roots will grow.

Just a bit concerned - are there any drainage holes in the bottom of that container?  I know mint likes damp feet, but waterlogging isn't good even for mint. 

20/09/2013 at 12:35

I never thought of that Dove

Thanks for the advice guys.  When I get home I shall take a closer picture of a leaf so we can rule out rust.

The container does have holes however, I may need to put more in.  I shall take the mint out and put it in its own bigger container.

Thanks again.

Interesting question MartinGT.  Those answers have been helpful to me, too.  Thanks everyone, Maggie
