What kind of Palm Tree are the two palms? Are you referring to the Canary Island Date that is also known as the Pineapple Palm?

Please let me also know the name of this type

That is a Canary Island Date Palm Tree. Very nice. You have had them 8 years now you said in that very same location? How much and how long did it snow for?

Botanically known as the Phoenix canariensis it can withstand temperatures down to 25 degrees. How long was is it snowing for? It still looks healthy to me. I do see the tips browning which is most definitely a result of the snow and freezing temperatures. I would recommend maybe taking some precautions before it may snow again. Or before it may go below 30 degrees F. You can use a wrap made of any clothe material to wrap the trunk. You may also bundle the leaves together and wrap them up as well with any type of clothe. This can prevent future damages to the Canary Island Date. You can also spray the palm with liquid copper fungicide, this can help the palm leaves from damaging and turning brown. The most important part is the spear. The spear is the newest leaf that is visible or a leaf that is coming out of the middle, it may be small but it is the life line of the palm tree. There is nothing you can do to reverse the browning already done but you can prevent more browning by using liquid copper fungicide and maybe a heating lamp or flood lights to keep the spear from dying. Also wrapping the leaves together can keep the inside a bit warmer. Add some mulch to the bottom area around the trunk. This will also help from the roots freezing. How cold does it get?

Well at the moment its 43 degrees F that very cold for this time of year and when it snowed it went down to 30 degrees F. It snowned for two days and didnt clear for a week, and their is some sign of brown leaves in the inner plant, so i pray that its just getting over the freezing weather.
Thank you so much I'm learning lots, my palm are my pride and joy, in this country you usuallly dont see them growing this well out of pots and i get lots of lovely comments from passer bys. I will definitely try your remedies.
Just to clarify wil i find the liquid copper fungicide at any garden centre? and do i spray it now even though the leaves are already brown?

The palm will resprout new fresh foliage when the weather warms ,i live in zone 8b and this happens every other year where it causes them to defoliate and brown and they recover RAPIDLY in the hot summer sun hehehe they should be ok so BE HAPPY!

[toni41264]

My palms are recovering brillantly, and one which im sure is female is actually sprouting fruit about five pods around base which is a delight to see ... im so happy that the snow didnt destroy them that they now get extra special treatment.

Do you have a picture of what it looks like now?

Wow, thats pretty interesting, I guess if you keep it covered and warm during the winter it would work, but its always dark and dreary in London, you probably have to spray it down for fungicide 3 or 4 times a year.

Wow That's terrible. Let me try and help you, What type of fertilizer are you using? What type of palm trees are they? How is London? Iv'e always wanted to vacation there but never got the opportunity to travel to that side of the world.
