Garden Plants to Install in Coastal Areas
Many homeowners that own beachfront properties are faced with the challenge of finding what to use when having a landscape install, having a beachfront property is great but when it comes to choosing plants for your garden there are certain plants that can and will tolerate salt sprays.
Therefore it is important in knowing which plants will work for us and which plants will not. In this article, we will be looking at some plants, grasses, and shrubs that will serve us well giving us that closeness with nature.
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 garden.
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. Pests such as the bougainvillea lopper can become a problem. Insecticides such as Sevin and soap sprays will help.
The disease of bougainvillea is called Bacterial leaf spot which is caused by a fungus. Bacterial leaf spot appears as a brown to reddish spot on the younger leaves, the leaves then appear rusty, and as the disease worsens 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 ask your nurseryman for more suggestions with a choice of fertilizers. Remember the label is the 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. Scaevolas 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 the law.
3. Oleanders are great flowering plants that have a nice showy bloom, the flowers of the oleanders are white, purple, light pink, yellow, white, or dark pink. When pruning be very careful because the sap can irritate your skin. The soil of these plants should be somewhat moist. The main pest problem includes aphids, caterpillars, and scales. Using liquid insecticides such as Telstar, upstar,t, 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 infected parts. When watering water at the base of the plant so that water does not get on plant leaves. Also applying a fungicide to your plant will help. A good fertilizer for oleanders is 10-10-10. Follow directions when it comes to using chemicals and fertilizers.
4. Yaupon holly will add that much- needed color to your landscape with its red berries, this plant makes a great garden feature. Keep holly well watered. Pest problems include mites, scales, leafminers, and spittlebugs. Applying insecticidal soap sprays will bring this problem under control.
Black Root Rot is caused by a fungus, this fungus lives in the soil and attacks the plant roots causing the plant not to perform as well, infected roots are black to dark brown, the plant also experience stunting of terminal growth and yellowing of leaves. Providing good drainage as well as applying a fungicide drench can help. Fertilize with 20-20-20. Read and follow directions when applying.
5. Star jasmine is a beautiful plant that shoots white flowers and has a wonderful aroma, adding this plant to your garden can really lighten up your garden area. Make sure to keep your jasmine plant well watered.
Scales and spider mites are the main pest problem, use insecticidal soap and your jasmine will be good as new. The disease of star jasmine includes wilt that destroys the roots. Signs include small roots becoming black but can be treated with a Bordeaux mixture.
Leaf blight is another disease that appears as brown-reddish spots on the leaves, leaves may also curl. The disease cause decrease in flower production. Applying Bordeaux to control the spread of disease. Fertilize jasmine with 10-10-10-10 0r 20-20-20.
Vines and ground covers
Vines and ground covers can also add that touch of flavor to your landscape and garden areas. Here are a few you can try
1. Lantanas makes a great ground cover, I have worked with lantanas and found them to do very well. These plants come in an array of colors and attract butterflies, they are low maintenance and can grow really well in little water. Pest problems include mealybugs, lace bugs, mites, aphids, whiteflies, and lantana leaf blotch miners.
Control these pests by using insecticidal soap sprays. The disease of lantanas includes botrytis blight and powdery mildew that is caused by a fungus. Powdery mildew appears as a white substance on the leaves of lantanas. The plant also loses leaves and leaves are deformed.
Prune infected parts and apply a fungicide. Lantanas are drought tolerant and over watering may cause root rot, allow the soil to dry out, and apply a fungicide drench will cause your lantana plant to bounce back. Fertilize lantanas with bloom booster or triple 10. read and follow the label when applying chemicals and fertilizers because the label is the law.
2. Portulacas are also great and can survive the salt sprays. This ground cover grows very dense and shoots small beautiful flowers. This is a low maintenance plant that can survive on small amounts of water. Portulacas are attacked by fungi that cause the plant to become diseased with root rot and white rust.
The use of a fungicide will bring these problems under control. Aphids are a known pest and applying insecticidal sprays will bring this insect under control. Fertilize with triple 1o.
3. Sea Purslane is great and really do their job, this ground cover spreads really well and can completely cover your garden area, care should be taken when installing. Plant in masses around palm trees, the flowers are small and may not be that showy but it adds to the overall garden design. Sea purslane can survive on very little water. Sea purslane has no known pest problems.
4. Geranium Ivy is are wonderful showy plants, I have worked with these plants over the years and in my opinion, they bring that soft touch. These plants are very delicate and should be handled with care. Geranium is often planted in hanging baskets and can be placed on porches or patios. Make sure that soil is moist, allow the plant to dry out a bit, and then water again.
The main pest problem includes aphids, spider mites, and whiteflies. Using a liquid soap spray will get the job done. The fungi of geranium ivy cause a disease known as gray mold, dying flowers, or drying leaves begin to rot once the rain and cold set in. Remove diseased parts and apply a fungicide, Fertilize with a light application of bloom booster. Follow the label when applying chemicals and fertilizers, because the label is the law.
5. English Ivy makes a good ground cover, these plants are known as climbers and can do wonders for your garden area but be careful because this plant grows vigorously and can take over your garden. It is best to plant them by themselves or under tall trees.
Ivies can survive on small amounts of water. Pest problems include mealybugs, aphids, scales, and spider mites. The use of insecticidal soap will get rid of the pest.
Botrytis blight is caused by a fungus, signs include gray fuzzy mold that causes dead patches to appear on leaves and stems, the upper parts of stems, and eventually, the plant will die. Prune infected plant and thin for proper air circulation. Apply a fungicide, bacterial leaf spot signs include dark patches on wet leaves, the patches turn brown and forms a yellow cycle around spots, stems will dry up, and then death sets in.
Remove diseased parts and thin plant for proper air circulation and then apply a fungicide. Be careful not to overwater because root rot may occur, decrease watering and drench the soil with a fungicide. Fertilizer with triple 20, triple 10, etc.. follow the label and apply fertilizers and chemicals as directed.

Also, infected areas are pink to reddish, Remove infected plants. Fertilizers include nitrogen, potassium, magnesium, manganese, and boron. Read and follow as directed because the label is the law.
2. Cabbage palms are good salt-tolerant plants, care should be taken, however, and be careful not to damage the trunk, keep well watered. Palms can grow to 30 feet.
The main pest of cabbage palm is cabbage palm caterpillar which is a pinkish small bug, Control of this bug is difficult and you should contact a person trained in this area.
A serious disease of sable or cabbage palm is called Ganoderma root and Butt rot which is caused by a fungus. The first signs of infections are withering and dropping of older fronds, younger growth is pale green or yellow in color, and stunted. The trunk collapses and the head of the palm may fall off.
Palm may also have a hollow sound when knocked, flat mushroom looking material is seen at the base of the plant which is known as Conk. At this stage palms, life expectancy is short and Palm may die within the first three to five years.
Remove palm parts that are dead, always avoid injury to the trunk of the palm when mowing. So far to date, there is no chemical control for this disease. Fertilize with palm special and remember to follow directions because the label is the law.
3. Bottle palm is a showy palm because the trunk is shaped just like a bottle. These palms grow to about 15 feet and should be given a good drink of water. Use palm special fertilizers and follow as directed.
