Roses generally prefer morning sun and afternoon shade in hot climates. They also require ample water during periods of extreme heat. Once the winter is over for good in spring, or in early fall, try relocating your rose where it will be protected from hot afternoon sun, but gets a good dose of full morning light.

Just in case your question is serious.... most plants find salt deadly, but there are a few that are somewhat salt tolerant. Look for info online, or see if you can get your hands on a copy of Michael A Dirr's book 'Manual of Woody Landscape Plants' which lists some salt tolerant plants. If your talking abpit a great deal of salt, it will likely kill most anything you put there, except for the weeds of course.

Few plants are salt tolerant. Dirr lists Rosa rugosa as being salt tolerant, even living on the seashore in pure sand. If you need a salt tolerant rose this would be your best bet. Most are around 4-7'tall. 'Fru Dagmar Hartopp' is listed as being 3'Hx4'w. This would likely be your best replacement for 'Nearly Wild'

Are they growing in moist, but well-drained soil? Are they getting several hours of sun a day? Is the soil staying bone dry? Is the soil always wet? Too much water, or too little will stunt growth, and often leads to plant death.Plant roots need air to breath in the soil, and if the ground is constantly wet, like from sprinklers running everyday, the roots suffocate. Check this out first before suspecting disease, or insects.

Are you feeding your roses? Roses are heavy feeders. I feed my roses the same food as my tomatoes, and I use organic products. I use compost tea with a little epsom salts. Make compost tea by mixing 1/4 compost and the rest water in a gallon jug. Steep this for three days and water your roses with it. Add a little epsom salts. Chopped banana peels buried under your roses are heaven to them. If you look at fertilizer packages, you will see three numbers 3-4-7. For roses, the middle number is the most important: that is your phosphorus, which promotes blooming. The first numer is nitrogen, responsible for the leaf growth. Try to choose an organic fertilizer with the middle number higher than the other two.

Nearly Wild is a floribuda, a cluster-flowered rose. Floribundas were bred from hybrid polyanthas, which have specied and China roses in their ancestry.
