Ideas for moderate shade area Arizona


AZPalms

Recommended Posts

So my Ptychosperma completely defoliated this winter after our week long cold snap with ultimate 25f low. It was pushing a spear then. Well fast forward to today. With the heat picking up (mid to upper 90s) I noticed the spear emerging white and brown rot. Gave it a tug and it came right out. Now all that’s left is the trunk. I have two options, 

1. Leave it and see if it pushes growth. 

2. Dig out and replace with something new. 

If I do replace it, any ideas on a smaller palm for a area in Phoenix that receives morning sun until Noon? It’s near a patio.

Mike at MB Palms showed me a lytocaryum last weekend that he said had no damage in the high 20's. I forget the species, but he's easy to reach. It was a very nice looking small palm, and from what he says it sounds very tough.

If you don't already have one,a triangle palm might be a good fit.I've had 1 planted in my yard for 20 years now in Mesa,Arizona.Went in as a 3 gallon plant in 1999 and it's done well,surviving our occasional freezes without any protection.(although it has completely defoliated a few times) It currently has less than 5 feet of trunk,so,gains height slowly,even though it produces several new fronds each year under our conditions.

I do have a Triangle on the east side. Does great with heat and cold! I’m bummed about this Ptychosperma

Try cutting crownshaft down on the damaged palm an inch at a time till you hit all clean tissue.Apply hydrogen peroxide to sterilize.It just might come back and surprise you!

A couple more friendly palm (no thorns) sugestions I've had very good luck with here in the Arizona desert.They've never shown any freeze damage after several years planted in the ground. First up - Ravenea xerophila.

Thrinax species also do very well here - I've grown dozens from seed,including the ones in my garden.

Thrinax radiata - very tropical looking and tough!

Thrinax,now Leucothrinax morrisii, is a slower grower but just as tough.

I poured some hydrogen peroxide into the the crown. Crossing my fingers it pulls through. I’ll give it a month or two and see what happens. 

How quickly has the T. Radiata grown? I have a small double and it’s been slow.

Both of the Thrinax I've just shown are 10 years old from seed planted at the same time.

Any of the Gaussia species will also work well in your described conditions.Be aware that this species does pull towards the light over time.You can dig and reset if it becomes a problem as they don't seem to be bothered by root disturbance.Great looking palm when younger as they have the appearance of a bottle palm but hardier.

You really need to cut the crownshaft flat to be sure you have removed the rot and it will also allow the area to dry out.Pouring H2O2 in the hole where the spear used to be just leaves water sitting on top of the rotted area,often making things worse.If the palm has a chance,you will see the new spear moving within a few days from the decapitation.

Well I’ll be darned. A week after pruning it’s head off and removing dead material, we have life. Part of the old spear poking its head out. Will it live? Will it die? Stay tuned to the next episode...

Unbelievably the palm continues to grow. I carefully revmoved it from its site. No root loss or damage. Check it out.
