New plants any advice appreciated

Hi guys,

I have just taken delivery of 2 Salix Flamingo trees any advice as to how to give them the best start? Also a Cherry Almond tree (Prunus Triloba). As a novice I don’t know what these mat things are do I need to keep them or are they just to stop the soil coming out during transit?

Thanks in advance

 

Those plants just need planting out.
Don't think I would pot grow them but others might.
See what they say.
Those things on the barbqe look really tasty, not.

I'd guess just there for transit.

 

The mat things will help suppress weeds and grass around the trees.

 

Thanks Nigel
