Guide to Growing Roses in South Carolina
Growing roses in South Carolina is a popular pastime for gardeners, and who can blame them? Roses are classic beauties, and they are the national flower of the United States. Their color ranges, fragrances, patterns, and size varieties means that there’s a rose for everyone! Roses also make for gorgeous cut flowers, and are largely hypoallergenic.
But how do you grow roses in South Carolina? How do you make sure your roses thrive and produce gorgeous flowers in South Carolina’s unique environment?
With over 50 years of horticultural experience, we know South Carolina gardening, and we want to help you ensure that your roses grow and thrive. We also sell gorgeous roses in our Seneca garden center each April, and if you buy a rose from us, we want to set you up for success. So, here is some guidance on how to grow roses in South Carolina.
Light
In general, roses need six hours of sunlight starting in the morning. The morning sun allows the night’s dampness to evaporate quickly from the rose’s foliage. Also, too much afternoon sun can stress roses during summer’s hot temperatures.
Watering
Water your roses in the morning to allow for evaporation throughout the day. Avoid getting water on the foliage. The less water you can get on the foliage, the more you reduce the possibility that fungus and mildew will infest your rose.
Water newly-planted roses every one to three days depending upon how humid the weather is and how much precipitation your area gets. For established, in-ground roses, give them one to two inches of water each week during the growing season. Established roses in containers require more water since soil in containers dry out faster than soil in the ground.
Fertilizing and Soil Requirements
Roses need well-draining soil that has a balanced mixture of sand, clay, and silt (called “loamy” soil). Including organic materials may help with the soil’s drainage. Roses do well with two to three inches of mulch on top of their soil, and they want a soil pH of 6.5 to 6.8.
For fertilizing, use a slow release fertilizer and feed the roses in the spring during active growth and/or when you prune them. You can also add composted manure on top of the soil to give your rose additional nutrients.
Pruning
Pruning your rose can help remove diseased or dead wood and encourage new growth. Plus, pruning spent flowers can encourage your plant to continue producing roses.
Prune roses in the early spring in South Carolina before the leaf buds open. Focus on dead wood and diseased wood. You can tell if the wood is dead if it is brown as opposed to green. Cut the dead wood all the way to the base of the plant.
Also, prune back any weak growth (think anything thinner than a pencil) as well as foliage or stems that stop you from clearly seeing each stem of the plant so that you can clearly identify any diseases or pests.
Consider sealing large cuts with a sealer to prevent rose borers and rot from entering the plant through the cuts.
Pests
Although roses are fairly hardy, they may be susceptible to aphids, black spot, fuller rose beetles, Japanese beetles, midges, powdery mildew, rose chafers, rose sawflies, scales, spider mites, and thrips. For guidance on how to get rid of these pests, visit our post, “Common Plant Problems & How to Fix Them.” For more guidance on how to treat your roses for disease, read our post, “A Beginner’s Guide for Growing Roses in South Carolina.”

When to Plant Roses in South Carolina
The ideal time to plant roses in South Carolina is when the outside temperature is between 40°F and 60°F. So, plant roses in spring or fall and after the risk of hard frost has passed. Consult our guide on South Carolina’s last spring frost to see what the earliest date is for when you can plant your rose.
How to Plant Roses
When planting your rose, ensure that your rose bush has enough room to grow. This means that you need to find out the expected height of your rose variety when it is fully grown. You can look this up online or reach out to a gardening expert at Head-Lee Nursery for help.
Then, use a measuring tape to ensure that your rose will have that needed space in the area in which you want to plant it. Plant your rose at least as deep into the ground as its first branches if you have an “Own Root Rose,” which means that it’s grown from cuttings and has its own root system. If your rose bush has a graft, then plant your rose bush up to the graft or up to the first buds.
