Salt tolerant plants
I have worked with salt tolerant plants for many years and have seen first hand how they can survive the harshest condition when it comes to salt sprays and still looks as beautiful and healthy as ever.
Here are a few salt-tolerant plants that you may consider when installing your landscape.
1.Bougainvillea makes a good salt tolerant plant with its many colorful flowers, but be careful because in the midst of all that beauty these plants have thorns.
when planting in masses of different colors can give you that rainbow effect. bougainvilleas are low maintenance and can survive on very little water. Pest such as the bougainvillea lopper can become a problem. Insecticides such as Sevin and soap sprays will help.
Disease of bougainvillea is called Bacterial leaf spot which is caused by a fungus. Bacterial leaf spot appears as brown to reddish spots on the younger leaves, the leaves then appear rusty and as the disease gets worse the spots become dark. The edges of the leaves may also be deformed.
Treatment includes pruning diseased parts and applying a fungicide. fertilize bougainvillea with bougain, 21-5-20 or you can ask your nurseryman for more suggestion with fertilizer. Remember label is law, so when applying chemicals or fertilizers read and follow as directed.
2. Scaevolas makes a great hedge, I have seen persons with beachfront properties plant these in masses. These plants grow very dense therefore it is good to prune a few of the middle branches to allow the sun to be directed to the lower branches to ensure full growth.
Scaevolas are slow growers and require small amounts of water, keep an eye out for spider mites and aphids. Overwatering can cause the disease to set in, signs include leaf wilt. decrease watering and apply a fungicide. Fertilize Scaevola with a high nitrogen source. When applying chemicals and fertilizers read and follow the label because the label is law.

Using liquid insecticides such as talstar, upstar etc.. will keep your plant in tip-top shape
Leaf spot disease in oleanders includes leaves that have brown or yellow spots when this happens, prune off infected parts. when watering water at the base of plant ensure that water does not get on plant leaves. Also applying a fungicide to plant will help. A good fertilizer for oleanders is 10-10-10. Follow use of chemicals and fertilizer as directed.
