Phoenix Canariensis Dying

Hi,
I bought several Phoenix Canariensis a week ago and now they look all but dead, I took them back to the garden centre that I bought them from but they will not give me a refund or exchange them, am I doing something wrong to lose so many of them please, pictures attached.

 

Have they been left outside overnight? Although we've had warm sunny days recently, it's been chilly at night (some frost here, but you don't say where you are). And were they kept under glass at the garden centre? If they were, the shock of moving them to the outside (cooler air, wind exposure, direct sun) might be the problem even if you didn't actually get frost. Even hardy plants need to be acclimatised gradually to the outside if they've been grown under cover, and these aren't hardy (H2 according to the RHS).

 

Where have you kept them, they are likely to have been grown in protected conditions and if you put them straight outside they wouldn't like it.
Have they been frosted?

 

Many thanks

From your replies I would say it has been caused by taking them from under cover and putting them outside, no frost but still chilly and windy here.

If I put them indoors over night will they survive and recover.

 

Well they are not dead but might take a while to look good, once the fronds are damaged they dont come back but they should grow new ones during the summer.

They will need potting on, and I see you are in Devon, but unless its very mild they will need winter protection at that size.

I cant grow them here in Kent, tried a few times and they just get killed by frost at a much bigger size than yours are.

 

Should I cut the dead fronds off.

 

No rush to remove them.
