Mint leaves turning brown on tips/shivering up

5 years ago

My mint which I had for two and a half week first started with mint rust. Tried with hydrogen peroxide diluted with water; one formula for spraying the leaves (kills fungicide on leaves) and another for watering the soil (kills fungicide on the root). Watered once every week (which is about the same time the soil dried).
I've stop spraying the leaves with the diluted hydrogen peroxide since beginning of this week since I saw that the leaves still shriveling up starting from the tips, even though I'm pretty sure there's no sign of fungus (white dust, colorful patches).
Right now I'm confused on what's going on, it's current situation is in my porch receiving direct sunlight from 7 in the morning till 6 PM. Being in Florida humidity goes from 70% all the way up to 90%.
I've heard that mint might prefer partial sun more often than full sun but I'm not sure, which is why I wanted to ask what should I do and what might be the problem with my mint? -Thanks

you have a lot of expectations of how fast things work in nature ... youve only had the plant 2 weeks.. and look at the list of things you have done to it ...

its stressed .. and it needs to settle down ... water it properly.. and ignore it for a while ...

i would never put anything i sprayed with anything .. in direct sun for at least a month or so .. i wouldnt want to burn the leaves from the remnants of whatever i slathered on said leaves ...

and next time you buy/get a plant ... and find anything wrong with it within days of receiving it.. return it to the seller ... or demand your money back ...

mint roots rather easily ... you might want to try rooting a few clean pieces.. and then perhaps.. just get rid of this mess???

on some level.. yo might be loving it to death ...

ps: its not uncommon to have browning leaves after spraying something.. especially if you went too strong with the spray .. or did it in sunshine.. in others words ... this may be related back in time.. and not something new happening ... so lets not try to harm it more by trying to fix an old issue ... or creating a new issue ... leave it alone for a month.. and just water it properly ....

I see no signs of rust on your mint. And if it did have rust within two weeks of purchase it already had it when you bought it and should have been returned. Stop spraying it and put it outdoors in semi shade. It looks as if it was grown in a greenhouse being sappy, soft and slightly etiolated. Healthy mint doesn’t need support. Yours needs to toughen up under natural conditions.
