How to help these baby bananas?

5 years ago

Hello! I'm new here, new to bananas entirely, and mostly new to gardening. If anything isn't following the rules please tell me!
So anyway I got these two patupi (the seller says patupi) off etsy (probably not the best place, but at the time it was my only option). The one appears to be relatively okay however the other (I've only had them for a day) immediately has the smallest leaf turning lighter green. What doesn't help is this same plant had it's largest leaf damaged during shipping- I saw the plants prior to shipping and both looked fine, so I assume it was shipping to my zone 6a that did this...
Now I'm keeping them indoors in my basement, the room is climate controlled and humidity controlled due to my reptiles and fish. Temperature never drops below 68 (averages about 72-75 F) and humidity usually ranges from 60-80% (higher than a normal home) and never drops below 50%. We have bright florescent lights and a little west and a north facing window, so it gets mostly artificial light (but a lot of that). So, needless to say, it's about the best room in the house for tropical plants. I also will be leaving for university soon, but they have a commercial greenhouse there where they'll stay during the winter.
Soil is about sand castle consistency, it holds its shape and is damp but not wet or soggy. I haven't watered since yesterday since I'm letting them acclimate due to being dehydrated in the mail. I did fertilize them with balanced fertilizer but *VERY* lightly, just a half spoonful for each pot and distributed among the soil. I hope this didn't cause problems.
Again, I'm very new and I hope this can still be fixed. If there's a way to upload images please let me know!
So, what would be suggested? Thank you so much!!

    Thank you!


    Here's both of them. The one is clearly yellowing and other than what appears to be some small burns, the other is doing well. However, the smallest leaf on the better one is slightly yellower than I'm comfortable with. And, since I live in zone 6a it won't be possible to bring them outside until I get access to the greenhouse, which won't be until January

    I don't know too much about growing bananas, but looking at your pics am getting impression you don't water your plants properly. Plants growing in containers should be watered slowly and very thoroughly until the water starts showing in the saucer under the container. I assume your containers have drainage holes at the bottom. Discard the water in the saucer in about 15 min. to half an hour. You should water them about twice a week, but the frequency also depends on the humidity in the locale.

    I see now. The containers do have drainage holes, and I watered them until the saucer was showing it. Soil is sand castle consistency. I did not, however, do it exactly this slowly so hopefully this can be fixed. I don't think they should be watered again until the soil dries as I think they're supposed to have a drying out period?

    As I said I don't have personal experience growing bananas. There is good info on the Net, I think. Read, for example, here https://homeguides.sfgate.com/care-banana-tree-pot-46014.html: "Keep the soil in the container constantly moist, and do not let it dry out."

    Brandon, Banana trees grow like Jack and the Bean stock. If your plan is it to grow indoors you will eventually have to cut this down unless it is a dwarf variety. I bought a Banana tree from a garden center in Ontario. It was 2 feet tall. Within a year it was 9 feet and almost as wide. Had 13' ceiling and it just couldn't be managed. This summer at Metro Grocery Store I bought a few dwarf banana trees in July for $4.99 each in 5-inch garden pots. Look how much they have grown in three months. They are on the top shelf. My plan was to buy 5 of these and pick the one that had the best potential to grow to maturity. A full-size banana leaf is about the size of a surfboard so you just can't just cut them back indoors. The dwarf variety is the only choice for growing indoors in Canada. Yes, they like moisture, high humidity. Your potting mix looks a little dry. Use a mix that has higher organics.

    Not sure if patupi is dwarf because it can reach 10 feet in height when ready to produce fruit, however, I do have access to a commercial greenhouse by the time it'll get that large. Not sure if this helps or not, but it typically reaches harvest time around 9 months as it is short cycle. When I leave uni I'll have my own greenhouse and grow them outdoors when summer hits, and keep the smaller ones in a
    Heated greenhouse.


    As for the plants now I have the yellowing plant is remaining stagnant while the other one is beginning to grow a tiny bit, mostly in leaf stem and leaf length. The bottom leaf on it is beginning to yellow but I'd assume if it weren't healthy it wouldn't have gained even a tiny bit of height over just the week I had them. It's hardly noticable in the pics but it's definitely happening.

    Thanks for the input. I was worried they were weak. You get what you pay for on etsy. The one plant that's clearly droopy is that way due to being damaged during shipping. Anyway, do you suggest I give them more ferts? I gave a very small amount to start as I was afraid of burning the roots since they were so small I didn't want to overdo it. I have a balanced fertilizer which I use. Also, since the one plant has visibly grown about a centimeter this week (albeit somewhat leggy) what does this say about the condition?


    As for temperate I keep the room in the 70's. Doesn't growth start at its prime in the 70's and it stops below 60°F? I make sure it doesn't get cold. Natural sunlight as of now would be at the expense of the plants' health, as upstairs not only does the rest of my family love it cold (too cold for me and I am a warm blooded mammal!) but we have cats and a dog who would gladly munch on the leaves. I will be moving to uni soon so they'll have a much better home shortly. I just need suggestions for them to hoof it for now. I'd like them to gain strength where possible, so any ideas I'd like to know.

    I'd avoid giving it a 'chemical cocktail'. Try organic fertilisers, they're usually safer. There's seaweed or fish based ones. Also lots of animal manure based ones. Those manure ones are usually well aged and not as deadly on plants as fresher manure.

    Plants have a variety of optimal growth temperatures. Some plants won't grow in the tropics as the temperature for growth is exceeded all day but not at night. Of course at night there's no photosynthesis, so the plant dies. Many tropical plants shut down with low temperatures and can also die.

    Not likely you'd know the history of the plants before you got them, so they might have been on an upward or downward trend. Any effects you see could be from either of those. It will take a little time to see the effects of their current conditions. Leggy growth is often the result of poor light.

  • 5 years ago

    I think it's difficult to tell what trend they're on. I'd like to say upward due to the shipping not being great due to my climate. For fertilizer we have turtles which have no shortage of manure- my slider in particular is very messy. Would this work?


    As for an update as of today. Both plants have grown a tiny bit yet (again) the bottom leaves haven't improved. The one plant has gotten most of its growth in leaf length and leaf stem length- the other gained a tiny bit of leaf length and it's clear it's trying to repair the large broken leaf due to it being less droopy at the base. Again, no new growth but improvement to the rest of the growth that isn't the bottom

    Update: I consulted a banana specialist for this. They said the pots are too BIG as they hold moisture too well and it won't dry out enough for plants so small. Never would I have thought pots too big would be a thing, but I guess that solves this mystery...

    Don't use fresh manure. I also have turtles but they're in a large pen outside with a couple of ponds. With lots of vegetation it's a natural setting so I don't see any manure, but guess it'd be like that of other animals. Manure needs to be left a while to break down a bit.

    Older leaves can die off quickly when the plant is in fast growth so don't worry too much about losing those if replacements are coming through. Once they're bigger, bananas are real water guzzlers, you won't have problems with over watering when they're in growth.

    Thanks, this definitely helps to know. I try to keep my tanks clean- our climate is too cold and full of predators and we can't dig deep enough for a pond so my 4" turtles are each in separate 55 gallon tanks with filters for 120 gallons. So there isn't really "fresh" manure. But once it JUST begins to build up in the filter I immediately clean the tanks and filters. So could I dilute the old stuff in the filter after washing it in fresh water and do just a tiny bit to not burn them? If it's in the filter it's usually broken down quickly by beneficial bacteria in a clean setup (which these tanks are crystal clear). If that doesn't work we also have guinea pigs, which I hear have a much lighter manure. Although they're not mine, they're my mom's, so she will expect me to be the cleaner of piggy poop if she sees me gingerly plucking out the feces! I spend a lot of time caring for the turtles so I'm short on time with that and school.

    And as for replacements, I haven't seen any new leaves, but they ARE focusing growing the newer leaf stems and newer leafs in length and width. They're also much more erect in their new tiny mug sized pots. So, I suspect new growth is on the way, it'll just take some time for them to adapt. I don't want to rush it, as they will pay off later.

    It is seven days after I got them officially. As tropicbreezent mentioned there's new growth coming in so they must be growing fast! The soil finally dried so this is why I watered it and it looks so wet inside. Doesn't help that it is clear, but the trees are much happier in here than the big pots. I didn't know pots could be too big, I've heard of too small but never the opposite counterpart. But for a tiny plant that needs good drainage a large body of soil isn't good, even if there is drainage. Learning new stuff by the

    There's never much said about turtle manure so it's difficult to find out much about it. Generally, manures decomposed anaerobically are considered more toxic than beneficial to plants. What degree of aeration there is in a filter I don't know so can't really comment. You could try it, but probably best when the plants have grown up more. If the plant starts to go backwards it should be strong enough to recover with a bit of flushing of the soil. Guinea Pig manure would still need to be aged. If you're into science you might find the chemical processes in decomposition interesting.
