Watered both plants this morning and went out this afternoon and the new leaf, still somewhat rolled is dry as paper. They've been outside for several weeks and have had several new pleats leaves in that time with no problem that I could visibly see. . The other is partial shade and seems to be doing fine. It's in the 100's here currently in Wichita ks and I water them a gallon every morning.

Sorry to hear that. A picture is worth a thousand words, though. We could be much more helpful if you posted one.

Varieties I supposedly bought: Manzano, Cavendish, Blue Java, Sweetheart, and Gros Michel.
What it seems I actually have: Brazilian, Cavendish, Namwah, Dwarf Red, Gros Michel, Pisang Ceylon, Veinte Cohol and SH 3640, and American Goldfinger. FHIA 1, Paggi and FHIA 17... Always room for one more.

Zombie Dave

Totally agree. Just gotta figure out how to host it.

Picture would help, but I think your post did state the problem.

Bananas need expire a lot of water thru the leaves to keep cool. They need a lot of water, especially during times of low humidity and high heat. Misting the plants 2 or 3 time a day helps to keep the plant cool and hydrated. Also, the plants will benefit from (partial ?) shade during the heat of the day (afternoon). ... You have two potted plants as examples: one in full sun not doing well; and one in partial shade doing fine as per you post.

Since these are potted, remember that pups growing next to the mother plant receives shade and cooling from thru water expiration by the mother plant. So pups and potted plants usually do not have the root development or pot size to support the water needs during high temperature days and low humidity. ... Florida excepted, it's a greenhouse down there.

What was the humidity and wind velocity? I have seen hot, dry wind kill new banana leaves. People often overlook the fact that wind increases transpiration.

Thanks for pointing that out. Since I mist my small nana patch daily if no rain is in sight, I have not considered even a mild blowing wind can quadrupedal the amount of water expired by the plant or evaporated from the ground.

especially in the plains hot and dry winds. from texas on up. Kansas and north have crops that flourish in july and on just because of that. to much moisture in the summer is devastating. in Kansas a banana with a permanent mister that was timed and used daily would probably be beneficial.

Another new leaf and hopefully picture. [IMG][/IMG]

1) the plant needs water and misting of the leaves.
2) Put some straw/mulch around the plant to keep the ground cooler and hold water in. the black mulch cloth doesn't do that.
3) the new sword leaf is growing through middle of the leaf with the curled edges. This looks like a 'choke' as the top of the pstem is bigger than the lower part. This is very odd looking.

May be Cinci will comment about the possible choke.

Sorry, I'm still learning the lingo. I've been watering them 2 gallons every morning. I'll up that. Posting a second picture and I'll add mulch. [IMG][/IMG]

You watered 2 gallon each morning????? ... Yesterday for my location, reported from the UGa weather center evaporation rate was .23 inches. Using a 5 ft radius around your plant (aprox 4 ft tall) for 80 sq ft. The approximate total water evaporation would be (80 s ft X .23 inches X .62) 11 1/2 gal of water. ... Not enough water daily! Use the drooping leaves as a quick guide. ... the soil shown in the picture is dry.

I can't find the evaporation rate for you location at the moment, but it is likely as much or more than my location.

Quoted from Banana Growing in the Florida Home Landscape:
"Bananas require large amounts of water and are very sensitive to drought. Drought results in increased time to flowering and fruiting,
reduced fruit size, fruit number, and crop yields. Bananas need about 4 to 6 inches (102–152 mm) of water per month for normal growth and production. Thus about 1 to 1.5 inches (2.5–4 cm) of water should be applied per week. This is especially important during prolonged dry weather conditions."


Using an average of 16ft circle around a mature banana plant, the 1 to 1.5 inches of water would be 125 to 190 gallons per week during drought & dry conditions. ... Roots can be as much as 16 ft laterally from the plant. I use half that as being the main root mass & ball for my calcs, but increase water if needed. Use leaf droop as a guide. ... Banana plants NEED a lot of water.

The 11 1/2 gal of water above only replaces/offsets the water lost to atmospheric evaporation. Additional water is needed for the expiration losses by the plant and to replenish available ground water if needed.

Sorry for the long post and another lesson. ... but many Nana growers do not realize how much water their plant really needs. Then under water the plant for fear of causing root rot by over-watering. ......

yes and some good mulch. and a watering can instead of a milk jug so you don't expose the roots.

Ok that makes a lot of sense. So definitely need a bunch more water. I'm on it. I'll hopefully be able to get mulch tonight. I read about choking now looking at it... that makes sense too. I didn't know if it was because its a different variety but the leaves on this one are very close to the leaf it grows out of. I really enjoy these plants and want more but need to learn more. You've helped a bunch! Much appreciated. [IMG][/IMG]

Zombie Dave

Another great point with the watering! Thank you!

edwmax

It could be the lack of water and heat stress causing the leaves to be so close together. No energy to push further. Improved watering should make to plant to grow and improve that situation. Sever heat stress can cause choking.

It's a basjoo also! When my basjoo gets 100F it looks pretty bad also! Mulch will help a lot! Leaves, straw, grass clippings, cardboard! Anything you have to cover the ground. They do prefer a thick layer of something they can get their roots up in though. 90% of Musa roots are in the top 1 foot! Very shallow. So keep that in mind also. You still look ok. It will recover just fine.

all that black, bet you couldn't step on it barefoot in the middle of the day. has to be drying up the ground. same with the blue tarping that has to be hot. make the whole thing like an oven. light layer of gravel?

I'll try and figure something else out for helping shade it. The black was to kill the grass. It's still not pushing the leaves up and out. Didn't know what kind it was. Now I know! I'll get more mulch and remove the black weed stop along with the blue tarp add continue to water and if it's still choked how do I rectify that? I'm misting also on top of the increased watering.
