How often to water king palms?

[FlaPalmLover]

I have a quadruple king palm. How often should I be watering it and how much? It's been looking a little dry lately. Does a quadruple king need more water than a single? I'd assume so?

King palms are water hogs. The more the better. They’ll live happily in a swamp. Are these palms in the ground or in a pot? A photo?

In the ground. I'm not sure if rock mulch is the greatest choice? One of these pictures was taken in the wind so the fronds look like they're mushed together.

The rock mulch is good for drainage but wood chips are better for moisture retention. As long as the rock is only the top layer , you should be fine . Like Jim says , they love water so be sure they have access to a regular water supply , especially in warm weather. Harry

I think when I planted it I did two layers of mulch because of how water loving everyone said they are, thinking it would help to keep the sun from drying them out. I think there's a layer of wood mulch under the rocks. The rocks were there before I planted these.

I upgraded my irrigation a few weeks ago and am running the system 2x/week for about 10 minutes but I'm not sure if any of the heads hit this planter bed.

In Florida sun, drench em. My King in full sun has 3x 3gph drippers on it that run 3x a week for an hour. Even with that, it’ll get some crisping in the late spring droughts. Unless in mostly shade with heavy mulch, you need to give them their own dedicated water source.

Every chance you get won’t be enough.

@FlaPalmLover at that size I've been putting one 1gph dripper on them running 40min/day every day in the summer and every other day in the winter.  A quad will need more, I'd probably put 2x 1gph on them now and add another 1gph next year when they are bigger.  You can overwater young seedlings (like strap leaf sized) but bigger ones like that have been fine directly downhill from a gutter downspout.  The new leaves look fine on those, so whatever you are doing seems reasonable.
