my new basjoo has a few brown spots on its new leaves too. it only has 3 but i just clipped one because it was almost completely dead. (i guess from shipping it).
it had one perfectly healthy leaf and one new sprout that is almost open but those seem to have small spots developing on them now too.

i have read that it is from over watering when the plant is not fully established and for letting water droplets sit on the leaves in the sun (or plant lamp in my case). i think my spots are caused by both of these factors.

do you think i should use a spray bottle to wet the leaves instead of dripping water on the leaves? more like a mist?

Please help!

take a look at my pictures to see the back left leaf that got clipped and the small spots on the other 2 leaves.

I had a couple brown spots on mine. I had spray misted the leaves on a down
cast day. Sun came out and there was some brown spots. Wet leaves and strong sun do not mix. I use more caution now. Haven't had a problem since.
Fungus can also cause this. You can try removing affected leaves if the spots seem to be spreading, as a fungus will spread.
Good Luck! Hope this helped.

yea i don't think its a fungal infection, it must just be the water situation. i know they are just baby leaves but im just so excited and eager to have a gull grown plant i cant help but worry! this is after all my first banana plant, let alone tropical plant.

i also have a Foxtail Palm tree on the way so that should be very exciting as well.

i just want to make sure the soil i have in my Basjoo pot is good for the plant if you guys don't mind...
its an all organic plant food comprised of earthworm castings. it is a very fluffy nutrient rich soil so i mixed sand in with it. about 75%soil 25% sand to help drain the water and provide air to the roots.

i also have it sitting about 2 feet under a plant growth light bulb that i screwed into an ordinary light fixture since the plant is indoors in my dorm room.

Default Re: what are the brown spots?

hello again!
i just noticed about a week ago a white powder on the clay pot i have my basjoo in. it is all around the outside of the pot and on the top and inner edge of the lip. ive tried cleaning it off with Clorox wipes and scrubbing the pot but it always comes back. ive read online that it may be a fungus and im starting to think it is because it looks fuzzy.
can this be whats causing the brown spots on my leaves? they just keep getting bigger (the spots not leaves)!
also the powder is not on the plant itself or soil at all... just on the pot.

any suggestions on how to fix this problem would help me out so much!

the first picture is from 9/17 and in one week the two small brown spots on the middle leaf (not the one that is still opening) have gone to about 2 inches long getting connected, and then a second large 2 inch spot formed on the tip of the leaf. that leaf is also browning on the edges as shown in the picture.

the other leaf in the same picture behind the one in the front had completely withered and got clipped.

now the new leaf that is now fully opend has some brown spots on the edges of the leaf.

the 3rd pic shows the white fuzzy powder (fungus?) on the pot.

Pleaseeeeee help me out i am getting worried and about to re pot the plant! (if i do will i be able to use the same soil?)

Hi Chris, I use mostly clay pots for my large collection of plants. White chalky
ness- on them is very common. This is caused by excess salts and is very hard to clean off. I have soaked my pots in clorox for days and it would reappear. Excessive salts is caused by a fertilizer buildup in the soil. Now, if the white looks like fuzzy puffs then it could be mealy bug attack. I personally do not reuse soil if repotted due to a problem. If you remove it from its pot,check for white wooly patches in the soil as this can mean an attack on the roots. I give my plants systemic treatment to prevent problems and to treat current ones. It is made by bromide and is an excellent product.
Again, your problem may be simply excess salts in the soil. Hope this has helped you. Good Luck! Raggedy

I just took a look at the pic again. It's salts. Repot in another plastic pot. Clay dries out too fast for banana plants. Use new soil. It should improve.

It's a leaf spot disease, caused by a fungus. It's not going to kill your plant, but it will not be aesthetically pleasing. I would recommend spraying with a copper fungicide, or other fungicide indicated for leaf spot disease. Sadly, the only way to get rid of it...is to defoliate your plant and destroy the affected leaves. You can try spraying the soil as well, or just repot into some fresh soil, making sure to wash all of the old soil away completely before repotting (that's what I would do). Try to keep the plant just a bit on the dry side if you are growing it inside. This fungus likes cool, wet conditions to thrive. Giving it the exact opposite conditions will hurt it. I would completely defoliate it though, especially since you only have a few leaves to begin with. You could wash the leaves off with a paper towel and a 10% bleach solution, and then spray the fungicide, and that may help to kill the spores. They hide in the middle of the black spots. If you get down there with a good magnifying glass, you can see them.

Default Re: what are the brown spots?

thanks guys, after looking at it again it seems to be the salts. i scraped some of it off with a razor blade and it wasn't fluffy any more. i guess it looked fuzzy because it was just building up a lot on the inner rim of the pot.
i just switched it into a plastic pot and re used some of the soil. i did put some more peat moss in the mix tho because i didn't have anything but organic earthworm casting potting soil and sand before.
however, while i was doing this a tragedy happened... the light i had clamped to my window sill had fallen on the plant and broke off the new leaf (the one that didnt have the bad spots on it, only a little on the edges). there is now only one leaf on the plant and it has the two big spots you see in my other post. do you think this plant will still be able to sprout more leaves? and will it bounce back from this quickly?

again thanks so much for the help!
