Salt-tolerant palms aren’t rare. In fact, this article mentions more than 10 of them! You can grow lush palm trees even if your water has high salt levels. Whether you do this indoors or out is up to you.

In this article, I explain what salt tolerance means for plants and which trees, shrubs, and crops do best with this type of water. You’ll also read everything you need to know about gardening with salt-tolerant palms.

Are There Salt Tolerant Palm Trees?

 Many palm trees are salt tolerant. In fact, the added magnesium could be just what they need! Magnesium helps palm trees produce chlorophyll. This is what’s responsible for giving them lush green leaves.

Are Sago Palms Salt Tolerant?

Sago palms are moderately salt tolerant. While an added magnesium-dose will do this palm well, exposing it to too much could be damaging. Only plant a sago palm if you know your water doesn’t contain high salt concentrations, or you’ll be able to alternate it with water containing less.

What Is The Lowest Maintenance Palm Tree?

Generally, palm trees aren’t high maintenance at all. Here are some of the lowest-maintenance ones:

How To Garden With Salt Tolerant Palms

The concentration of salt that a palm tree can handle comes in three levels: high, moderate, and slight. Besides considering the weather, soil, and lighting conditions, you need to keep the salt concentration of your water in mind. 

  • High Salt Tolerance: You can regularly expose palms that have a high salt tolerance to water containing high salt concentrations. 
  • Moderate Salt Tolerance: If your palms are only moderately tolerant to salt, you should ensure they’re protected by plants with a higher tolerance. These will shield them and soak more salt from the soil.
  • Slight Salt Tolerance: These palms don’t really have a tolerance for salt. You should avoid exposing them to water with salt concentrations.

How To Care For Salt Tolerant Palms

Maintaining a salt tolerant palm is no different than caring for one that doesn’t prefer salty water. The only difference is that these palms are hardier to salt water and perfect for use in coastal gardens. You’ll still have to meet their soil, watering, lighting, and pruning needs. 

If your palm tree is hit by saltwater breezes, it’ll survive. Any salt absorbed through the soil won’t damage these palm trees, and they may even enjoy the extra magnesium!

Companion Plants For Salt Tolerant Palms

If you prefer having more than just palm trees in your garden, you should choose plants that pair well with them. Succulents are an excellent first choice, and there are many to pick from. You can add lots of color to your garden when using these, and even place them on your porch in pots if this is what works best for your aesthetics.

Shiny or waxy shrubs will look good next to your palm trees. I suggest selecting evergreen ones like the pink rock rose, Mediterranean saltbush, box-leaved honeysuckle, and fortune’s spindle. These will all do well in the wind, sand, and salty conditions. 

3 General Tips For Growing Palm Trees

  • Palm trees don’t care much for direct sunlight. Plant yours in a spot where it’ll get indirect light to ensure they’re not overexposed.
  • You don’t need to fertilize your palm trees, but they can be healthier if you do. Find a fertilizer that balances the saltwater levels.
  • Trim your palm tree with caution. You might be tempted to cut leaves short if you experience windy conditions, but over-pruning can make it harder for your tree to survive. 

Conclusion

You can grow salt tolerant palms indoors or out. Whether they’ll be hit with saltwater breezes or receive water with a high salt concentration, the palm trees mentioned in this article will thrive. Caring for them is pretty straightforward too. The only difference between salt-tolerant palms and others is that they like more magnesium!
