OAK TREE - planting oceanside #903240
Asked May 28, 2025, 9:33 AM EDT
We recently acquired two (2) red oak trees for planting at our oceanfront home.
Although the local conservation group has decided that this is a good thing, my concern is that it may be a ‘good thing’ for some homeowners further inland.
But that for our property. There is simply too much exposure, and the soil is too sandy (basically, it’s sand – with ‘some’ organics)
I would appreciate your thoughts on the concern. (Any insight at all will be greatly appreciated in advance.)
The property is on the southern shore of Long Island NY (https://maps.app.goo.gl/dqTLnHoRLL8TfX5z8)
Suffolk County New York

Hi Mark,
I can address generally the suitability of red oak to this growing environment but it would make sense to have a certified arborist visit the site and assess specifics before you commit. A coastal gardener's challenge is not just low organics in soil and wind but also salt damage. Plants are vulnerable through root absorption and salt spray on the foliage. Beyond 1/8 mile from the sea, salt tolerance becomes less of an issue, so perhaps your siting is not vulnerable.
Red oak are considered highly tolerant of very sandy coastal soil like yours but you would still need to amend the planting area with organic matter and mulch the trees to maintain moisture. Red oak is not known, however, as a salt tolerant species. I am linking you to a List of Trees and Shrubs for Coastal Environments from the University of Massachusetts that can guide you to some possibilities, if you feel salt is a prominent consideration. If in doubt, send a soil sample for testing at a Cornell Cooperative Extension lab.
I am also linking you to this article on Coastal Gardening in the New York Region from NYBG's Plant Information Service which includes general information on maintaining plant health in your setting.
To find a certified arborist to advise you can use the International Society of Arboriculture "Find an Arborist" tool.
Good luck with this exciting planting project!
Kind regards,
Leslie
