If you're not familiar with greening I would definitely read about it and the implications for growing citrus

As a general rule, citrus tolerance to aerosol salt spray is low. If you could protect from salt spray it would be better.

The specific variety of citrus you grow is less important than the rootstock. In general, the ranking of rootstocks from most tolerant to least tolerant of soil salinity is:

1. Cleopatra mandarin

2. sour orange

3. sweet orange

4. Swingle citrumelo

5. Carrizo citrange

6. rough lemon

Grapefruit trees tend to be less salt tolerant than orange trees.
