Madagascar Palm leave tips turning yellow/brown

[stephenAZ]

This Madagascar has been beautifully healthy all year since planting in the early spring. Every leave was a perfect healthy green all summer.

Suddenly, it has the tips of leaves turning brownish or yellowish.

Any advice on what this might be? We had an unusually hot summer this year, but it seemed to be doing fine through all of it until recently.

Or is it possible it’s a fungus of some sort?

Whenever I see brown leaf tips, I first think of under or over watering.

You mentioned the plant is just getting established this year and it has been unusually hot, have you been providing supplemental water with what appears to be an irrigation line sitting next to it? If not, perhaps the establishing plant needs a bit more water acclimating during this heat?

If you are providing water, are you waiting long enough between watering that the ground dries out under it so the lower ends of the roots are not sitting in wet soil for prolonged periods of time? One long drench and waiting until the soil dries out is much better than frequent short waterings. Also, not sure how your tap water is there but if using it frequently, perhaps salt or chlorine might be impacting the roots/leaves?

Although I have never experienced it, I have heard that excessive salt from fertilizers can also cause brown tips. If you are using fertilizer, perhaps back off on this?

All complete guesses on my end but this is where I would start.
