Hi everybody,

My mint has finally decided to bush out after much worry but the leaves have white spots on them.  I've had a quick inspection and can't see any infestation plus the basil and parsley pots look alright (i.e. no spots on them) and they are next to each other.

Here's an example I found of what it looks like:

 I've checked around and can't see any insects plus the neighbouring pots of basil and parsley are not showing similar signs.

Does anyone have any advice?

I have also bought this bug spray from B&Q http://www.diy.com/nav/garden/garden-care-watering/pest-weed-control/insect_control/-specificproducttype-insect___bug_control/Bug-Clear-Ultra-Gun-750Ml-33-Free-11907627 but abit hesitatnt on using it incase I poison myself.  I heard soap and water works just as well.  Does anyone have any advice?

 

Many thanks!

Hi Mizzli  Can you try to post the pic again please - click on the little tree on the toolbar and you'll get the instructions.

Hi Dovefromabove,

Thanks for your post - I noticed half my post was cut off when I submitted it. It's happened quite a few times now when I have created a post.  Must be a bug!

Thats a similar image I found on Google but will post one up of my mint leave when I get home later this evening!

Dovefromabove

I don't think it's an infestation - it might be a deficiency in the soil - do I remember that this mint got a bit waterlogged?  Have you potted it on recently and now it's bushing out and growing well?  

I really wouldn't worry about it - it's really hard to kill mint, particularly at this time of year.  Don't spray it with anything as I presume you're going to eat your mint.  I think it'll grow out of it  and even if it doesn't it's not a problem - there are some variegated mints so it might have a bit of variagation in its DNA.

Hi Dovefromabove,

Thanks for your advice.  I think my mint was over crowded and growing from the kitchen windowsill.  I bought it from a supermarket with four plants in one pot and it began to get leggy.  Afterwards I repotted it and split then put it outside and it has grown relatively well again - except for the white spots!  I will post up a picture of them tonight when I get back!

Thanks again.

Finally got a pic of my mint leaves: 



If it's a deficiency in the soil, do I need to add anything like supplements? It was repotted not that long ago.

 

Hi Mizzli

I think the white spots are physical damage perhaps caused by hail. The young leaves which have emerged perhaps after the hail storm look to be unaffected.

Quite a few of my plants look very similar. The white spots took a few days to appear after the hail, but I have seen it before.

I have the same white spots on all my mint  plants.  The cat-nip has leaves that have white spots and the whole leaves are ghost like. I live in California and these plants have never had hail.  All plants are in pots, all got spots at about the same time this year.
