Washingtonia robusta overwintering

6 posts in this topic

Hello, i live in Europe, in Czech Republic. My place is in zone 7a/b, this year was a bad winter with low of -12°C (for y'all imperialists 10°F), usually about - 8°C (17°F). My idea is to make a box from polycarbonate, cover the ground inside the box with styrofoam, roll the tree into some light wraps and then with heating cable (64W 4m, y'all imperialists 13ft). Is this possible or does anyone have a better idea how to protect the palm? I can get a lot of materials for free. I planted the tree this week, its like 60-80 cm high.

You should have procured a washingtonia filifera so you wouldn't have to protect it.

The winter in my country is extremly wet and filifera 1)isnt available anywhere 2)would rot.

filifera doesn't rot any more than robusta in the winter. I  can send you a few seeds to germinate and try.

According to a tests by few guys that grow palms in our country (although in colder part, i think they post here too as experimental garden in 6b) filifera can't survive our winter because of the high quantity of water (its not that cold but it snows and rains and how temps jump between + and -, the snow melts and the ground is extremely wet) Its true that these guys have their garden in a very wet part, my garden is highly affected by oceanic climate (unstable weather) but it is drier than the rest of my country, mainly in summer (temps about 30-35°C, sometimes doesnt rain for few days or a week)

If you have seeds of clean filifera i would be interested but i dont know how bout the shipping price. Thanks

    • Palm advice please
      By Plantasexoticas
      Hi everyone, so I purchased a Washingtonia around a month ago. It was in the nursery sitting in a lot of cold water with around 20 others. They all looked quite healthy so I got one. Since putting it into the warm and dry it has pushed up 2 spears both of which are partially rotted, the first has opened but has lots of brown marks, the second is worse but it's still pushing up the spear. Question is if the spear is being pushed up and it doesn't pull out should I worry? Or just let it push them up until healthy growth recurs? I did photograph and show them to the nursery and I said it was probably due to sitting in cold water over winter (they had flooding)- they have since moved them to the dry.

      I know, washies are easily germinated, but I love when I see that first little blade emerging for all of my seeds. Why not share the moment. 
       

    • Washingtonia Robusta in Virginia Zone 7a/7b?
      By PalmTreeDude
      I was thinking in March that I would plant a Washingtonia robusta here in Virginia (zone 7a/7b). Do you think I should do it? Of course, every winter (starting in early November, when tempature start getting below freezing) I would protect it. I heard they are a good palm to protect in this zone because every spring, since they are so fast growing, they come back nicely and look great in summer. That would really be an eye catcher here. What do you think?
    • How Do I Get Water to These Seeds? Help!
      By PalmTreeDude
      So I am trying to germinate these Washingtonia robusta seeds that are on a heat mat but the water keeps evaporating before the seed can get to it, every time I pull the paper towel out it is dry and the top of the inside of the bag has water drops all over it. Is there a way to fix this?
