How to - Sunburned plants

[Jdiaz31089]

I sooo wish I had an established canopy! I have two d. baronii that were in mostly full sun and had been doing great until this last heat wave. We hit 109 degrees F several days in a row. My poor baronii got a terrible sunburn. And it wasn't for lack of water either - I water these things religiously so as to make sure they don't dry out. 

I planted them where they are in full sun, expecting they'd eventually be shaded by some fast-growing queens several feet behind them. Now I'm wondering if I should move them. What would you do for these guys? The bases of the petioles are not damaged, and the trunks are not damaged either. Should I shade them and move them later? Will they grow more tolerant of sun exposure with age?

This is the one with the worse burn - planted to the right of the Phoenix reclinata. You can see the burned out frond laying over the succulents.

The center spear is still green - only slightly burned.

The small sucker is also damaged, but in better shape than the larger stem.

Dypsis onilahensis fared better, but some of the old fronds burned a bit.

They look too bad. I had the same experience with other small palms and always, after weeks or months, death.

Same like yours, burned leaves, green petioles and spear, but the spear never grow and always is browning or roten.

I think baronii is not a full sun palm in a climate like yours.

May be this is a good oportunitiy to plant other palm better for this place.

For the most part, I've had fatalities after overexposure as well. With my 2 Jamaican Tall coconuts, I saw leaf burn early on 2 fronds and put a cover overhead for them.  They are now healing and pushing fronds.  If you are able to "tent" them, it may give them a sporting chance at least.  Good luck, and as Monover said, it may just give you an opening for something better if they don't make it.

Shade cloth is really your best option until they mature or canopy is established.

As bad as it was, be glad 109f was the worst you experienced. You should see all the damage 119-124f has done here.. Don't ever recall seeing fried, established Oleander, or obvious sunburn on Date Palms, ever. Hammer is right, shade/ shade cloth can be a life saver, all though it may not be enough to completely stop sun damage. Lots of stuff I threw under shade/ into shader spots around the yard/ under the patio got badly torched. Even so, there have been some unexpected surprises.

I feel ya bruh! I'm surprised that my 3 gallon D. leptocheilos youngins are burnt even in a covered and screened patio! What the actual heck?!!  Did I miss something? Is this a palm whose seedlings need full shade?

Best way to go.
