Default Dwarf Banana Stunted Growth

As the title says, I believe my plant is suffering from stunted growth or even worse death. I have a indoor potted plant which is about 26 inches.

I've had the plant for about a month & a half and within the first week a leaf shot up and unrolled. Very shortly after that, about the 2nd week in october another leaf popped up. It has now been over a month and that leaf is still unraveling as opposed to the first leaf which unraveled in a week.

I ruled out the weather being the cause of the slow growth because two pups have sprouted and have been growing inches a week.

The only thing I can think of is being the cause is over misting.
Around the same time the second leaf was coming up, I started to mist my plant heavily several times a day until there were big droplets on the leaves. I read that when this happens the stomata closes up preventing photosynthesis from taking place. In addition, I read that when the mother plant is stressed she will give everything she has to the pups.

Oh and theres another problem lol. I bought an areca palm about 2 weeks ago and it had a fungus knat infestation. I was able to remove flies but I did notice a fly and a larvae in the soil of my banana plant. I know they feed off roots but I doubt this is the case because the stunted growth was happening prior. Anyway I'm going to dry the soil out so if flies do hatch the soil will be unattractive to them.

Any advice would be appreciated. I'm located in NYC.

Leaves take way longer to unroll indoors. Try getting more light on it. Picture would say a 1000 words.

In the following pictures is my Dwarf Banana Plant named Luquillo. As you can see from the picture there is an unrolled leaf which has been probably in that exact position for 2 weeks. However, the pups grew inches both within those two weeks.

Another thing to point out is the wilting of one of the leaves on the main plant. It has been incredibly slow whereas before the wilting happened within in 3-4 days.

Possible causes:…

Plant went into shock from being repotted while the second leaf was popping up so that stunted growth.

Fungus knats could've slowed down growth by eating at roots all though I have not seen one fly emerge from the soil for about a week now.

Plant went into shock from over misting. (I was misting heavily all day, until big drops would form on leaves, several times a day). Stomata closed and interfered with photosynthesis. Mother plant gave all her nutrients to pups to secure her replacement. This would also explain both pups shooting up fast within the last 2 weeks.

I'm assuming that ac unit is off right? Could probably use a bigger pot but at this time a year I would wait. Only 3 leaves from what I can see means less light intake = slower growth. Seems bright but remember behind glass is classified immediately as indirect light. More light is better.
In the last picture it looks like a cigar leaf coming through before the previous leaf opened. This happens when conditions change. I wouldn't worry till you see something negative. Leaves look healthy so plant is watered well. Pot is a little small but it'll be OK for winter. Whats the temp in that room?

Well its been getting cold last couple days. I would say temp in the room has been 65-72 max. The pot is 8 inches in diameter and I received it in a 6 inch pot in diameter. I read not to go bigger than 2 inches when repotting.

The reason Im worried is because the plants are wilting before they even unroll. As you see the unrolled plant in the middle, has a split already. Yes AC unit is off.

I have noticed with my plants when I separate a pup or repot sometimes they will pause a few weeks then start back up again. Seems to happen more when I disturb the roots too much. A lot of times I will have a new cigar leaf come through the not totally unrolled last cigar leaf. Most likely you will see new growth within a week or two with a new cigar leaf popping through. I wouldn't worry too much yet.

Hey guys today I picked up my pot off the saucer and noticed what seems to be a small white bug.

Im not sure if this is the fungus knat larvae or what. It was crawling and moving in different directions slowly. I can only think of it being that because of the the recent houseflies that have emerged from it.

Can anyone help me determine what it is.

Its the small white spec in the bottom center

Ok, so I lifted my potted plant off the saucer and today I saw a few pests. I'm almost 100% sure that larvae is connected to the Fungus gnat. Also there seems to be 2 kinds of white bugs. One seems to be a larvae thats crawling slow the other seems smaller and is crawling faster (is this larvae in earlier stage?)

Also there was a reddish/brown bug also in the saucer about the size of a grain of pepper, I filmed him in the first video. Im not sure what the hell that is and I don't think its connect to the fungus gnat? Could anyone help me out? All 3 videos are below. The reddish thing is in the first video I believe

Hiya Re: Dwarf Banana Stunted Growth

Ok,so I think I have identified all the pests/insects.

1) Fungus gnats: The flies caught around the pot and the sluggish white larvae on the saucer.

2) Spring tails: The small white crawling creatures on the saucer, that I thought were Fungus Gnat larvae but later changed my mind because these had legs.

3) Orabitid Turtle Mites: The reddish turtle looking insect found on the saucer.

I believe the last two are harmless and the first one is my real issue.


I attached 2 photos. The first photo is what I believe to be fungus gnat larvae. Elongated white body and very sluggish. Its enclosed within a green circle.

The second photo is what I believe to be Orabitid Turtle Mites and Spring Tails. They are encircled in blue circles. The Orabitid is on the left while the Spring Tails are on the right. If anybody agrees or disagrees can you post a response please.

Very hard to tell, but when I see white bugs I think aphids. Either way I would spray with a mixture of plain dish soap (not the ultras) and horticulture oil (or neem oil).

You are right. Yesterday after Doug more research I became even more confused & I'm second guessing my assumption of one of them being a springtails.

What I'm thinking now is a combo of Fungus Gnat & Root Aphids. Today I saw a clear red clear bug that was super small and I know that is not in the Fungus Gnat lifecycle.

Either way I ordered neem oil & it should be here by tomorrow. So I will take care of it hopefully. In the meantime I'm cutting back on the watering the
