Can you bury a tree slightly in a raised bed?

Hi there,

Along the edge of my garden I have a palm tree and I believe an olive tree (although it never has olives so probably not) and was looking to make a raise bed along that side, if I put in a fence and fill no more than a foot deep with soil, would that affecy the trees? If their trunks are a foot deeper in soil?

Many thanks in advance,

Jason

    Most trees will suffer if you bury the base of the trunk and roots under more than a couple of inches of soil.  The trunk can easily rot at the base but the main problem is that there are roots surprisingly close to the surface and those need air which will be cut off when buried.  Have a look at this pdf from some experts:

    You may get away with it in some cases - depending on what type of palm it is, that may survive.  Can you post some photos to try and identify your trees?

    Hi Bob,

    Thank you for the info, I will give the PDF a read, these are the two trees, info you are able to ident them that'd be great as I'd love to know more about them.

    Regards,

    I'm not great on ID'ing palms but I think that might be a windmill palm (Trachycarpus fortunei) and the tree looks like a Eucalyptus, but couldn't tell you which one.
    Personally, I wouldn't risk burying the roots of either and would probably try and dig up the palm and replant at the higher level.  Obviously you can't do that with the eucalyptus and killing that one would leave a dangerous situation (it could fall) so I would cut that one down and hope it re-grows after you raise the border.  Eucalyptus are fast growing trees and if burying the roots doesn't kill it, it will soon be shooting back up into the sky.

    Thank you, I will look those up. I don't know if I'd dig up (and risk killing) the palm.... what I think I may do is make a raised flower bed and then make an inner fence around both trees allowing them to be at their original level and then maybe put some decorative stone/bark on the soil around them allowing them to breathe and also avoid rotting.
