Please HELP!!!: When to leave dead fronds or cut them off?

I have a Dypsis Lanceolata aka Ivovowo Palm aka Madagascar Blue Bamboo. Yes, it's exotic and rare, unfortunately, but visually it's not far off from the common King Palm, main diff being the lower trunk has a rich green cucumber-like skin segmented by white rings. Hence, giving it a bamboo look.

I bought it at a nursery that kept them under shade cloth. It was perfectly healthy and the fronds were green. When I got it home I discovered it was too tall (12') to fit under my shade cloth (11' high). I knew it was in immediate danger of too much sun exposure but I tried my best to find it partial shade though its height was an issue wherever I put it. Sure enough, within two weeks the fronds were barbecued well-done reddish brown, including the central spear. However, two months later there's a second spear shooting up and it's perfectly GREEN!

So here lies my dilemma. Do I cut off the burnt limbs (including the brown spear) to reduce stress, reduce spreading, and allow it more energy to produce new fronds? Or does the tree need the damaged fronds and dying spear for some reason I'm unaware of?

Trimming off the dead stuff will allow it to fit under my shade cloth. The guy at the nursery that grows these trees said to leave the dead stuff on no matter how bad it looks.

I honestly don't know what to believe.

Anyone?

Maybe you could ask the guy at the nursery why exactly he advised what he did? Perhaps he just meant to leave the plant some leaves with which to photosynthesize as well as it could, while it generated new growth?

Once a plant part is dead, removing it has no effect on the plant. Neither does leaving it. Neither option "reduces stress" nor promotes or prevents the plant expending energy on the dead part - since that part is dead, it's not expending energy on it anyway.

If the dead parts are providing shade to the new growth, and you remove the dead parts be prepared to protect the new growth. You say you can move it under your shade cloth, so do that promptly.

Dead fronds will also protect the tender growing tip from frost, until it has sprouted well enough to be strong enough to protect itself. Once that has happened the old parts can be pruned off. It is not now frosty, and the new growth is growing long enough before the frost comes that it probably won't need the protection of the old leaves (especially under the shade cloth), so, again, cut them off.

Thanks for the input.

If the tree doesn't care either way about the dead parts, it makes more sense to remove them and move the tree out of the scorching sun and under the cloth. That might be its only gain and should be a huge one. Otherwise, it stays where it is and continues to burn.

Is there any way you could DIG down and plant the palm in it's container into the hole made to take the pot, this sinking the pot INTO the soil will allow the palm a bit more growing room at the top.

IF the containers are to be placed on slabs or concrete etc, then the only improvement I can think of is to make a shade / shelter up from an old sheet / cloth, sink 3 very tall 2X2 inch wood stakes into the area and tie the cloth like a flat sale above the palm.

It seems so sad to watch a majestic plant burn itself to a frazzle IF there could be a solution for a bit of shade.

Hope you can save your palm as it's working hard to try make it through the overpowering heat and direct sun.

Best of luck and Kind Regards.
