The most effective way to transplant a Confederate rose bush is to bury a cutting in sand and transplant the developing bush when it is about six weeks old. The supplies you need are two 1-gallon nursery buckets, pruning shears, a garden hose, a cold frame, a clear plastic bag, potting soil, mulch, sand, perlite and a shovel.
- Prepare one of the nursery buckets
Fill a 1-gallon nursery bucket with 4 parts clean sand and 1 part perlite. Agitate the mixture with your hands until the perlite is distributed evenly.
- Soak the sand mixture
Saturate the sand mixture using a garden hose, then remove the hose and allow the sand to drain for an hour.
- Make the cutting
Snip an 18-inch stem section from the base of a Confederate rose bush. The ideal cutting is about as thick as a pencil.
- Trim the bottom of the cutting
Use the pruning shears to slice the bottom of the cutting at a 45-degree angle.
- Embed the cutting in the sand
Stick the angled end of the cutting into the wet sand mixture. Push the cutting down until the bottom half is embedded in sand, then press the sand in and around it.
- Cover the container, and place it outside
Place a heavy, clear plastic bag over the cutting, and set the bucket outside. The ideal location is in a cold frame or against a wall that faces south.
- Water the cutting
Check the sand's moisture level frequently, and add more water when the top 4 inches feel moderately dry. Pour the water gently around the cutting. Do not flood the bucket.
- Wait for root development
Give the cutting six weeks to develop a root system.
- Test the roots
After six weeks, test for root development by tugging gently on the stem's base. Keep the cutting in its rooting bucket until it manifests additional signs of growth, such as small leaves or branches.
- Prepare the second bucket
Fill the second 1-gallon nursery bucket with potting soil.
- Transplant the young bush into the second bucket
Once the bush develops leaves, scoop it out of the rooting bucket, and place it in the container of potting soil. Set the plant in a shady area for about two weeks.
- Transplant the bush into the ground
Slowly pull the bush out of the bucket. Dig a hole in a sunny location, at least 10 feet from other bushes. Set the new bush in the hole, cover the roots with soil and spread a 2-inch layer of mulch around the base of the plant.
