Too much or too little water, picture of leaf

nph · 07-31-2010, 07:48 PM

Hi,

Is this a sign of too little or too much water? It is triple digits in the Dallas area right now. I have seen this on more than one banana so the timing tells me that there was a day that they were too dry or too wet due to sprinklers, but on the other and with near triple digits everyday I am leaning toward too dry.

What do you think?
Thanks

-Peter

P.S. For some reason the picture is rotated 90 degrees when I upload it. On my computer it is vertical and looks ok, sorry about that.

You can rotate it in your gallery if I am correct.

If anything, too little water. However, in 100+ temps, it may be unavoidable regardless of how much you water. The problem is made worse in low humidity situations such as AZ.

I was thinking the same thing about my plants. I had to cut some down because they looked terrible. I was watering quite a bit since it has been sunny and 105-110F daily. I turned the drip system off about 5 days ago and haven't watered since. None of the plants look water stressed yet and a dwarf cavendish remains to do quite well. I cut down an ice cream and cardaba. Both are sending up new suckers that look healthy and without water-stress.

Other plants in the area that haven't had water in 5 days are queen palms, dwarf dates, king palm, and cannas.

A lot depends on your soils ability to hold water.

How much are you watering it?
Looks dry to me.
Starting tomorrow it is predicted to be 95-100 for three days I will be watering 2 gallons per large plant each day.

I know it's more humid here, mine seem to thrive in hot weather as long as they get water.
The more water the bigger te plant.

looks like leaf burn maybe keep the sprinkler on it to keep it cool. Even though they are tropical, banana plants begin to slow down at about 80° F and stop growing entirely when the temperature reaches 100° F. High temperatures and bright sunlight will also scorch leaves and fruit, although (generally speaking) bananas do best in full sun.

I think this is a really good point! I think bananas in hot dry conditions can't move enough water from the roots to the leaves regardless of how much water is in the soil. I think that is what happened to my plants. They looked like your picture, so I stepped up the watering. Within a week, they looked 10x worse. Since I stopped watering, they have started to improve.

What's the humidity like?

nph · 08-01-2010, 11:50 AM

Well this is Dallas so humidity is right now 45% so during the day I would expect it to be between 30 and 40%.

I think your best option (if possible) is to dig down a bit and feel the soil.
