Floribunda roses are characterized by a bunch or group of roses on each stem -- unlike the tea rose or the type of rose you buy from a florist that has one flower per stem. Floribunda roses do not always have a scent, but they are more disease- and drought-tolerant than other types of roses. They can be purchased in the spring as bare-root plants packed in sawdust and wrapped in plastic or as container-grown plants most times of the year. They are tolerant of cold weather in USDA horticultural zones 5 through 9.
Find a place in the garden for planting that receives about six hours of sun each day and has good air circulation. Unpack the rose bush from its wrapper and remove all packing material. Soak the bare roots in a bucket of water for 12 hours before planting.
Dig a hole deep enough that the rose bush will be planted at the same level it was in the nursery container. On a bare-root rose bush, look for the soil line where it was previously planted at the base of the plant just above the root zone. Make the hole wide enough that the roots can spread out and not be crowded.
Mix soil that was removed from the hole with compost before adding back into the hole. The soil placed back into the planting hole around the roots of the rose bush should be 1/2 soil and 1/2 compost mixed together well.
Add water to the planting mix while adding the soil and compost mixture back into the planting hole to eliminate any air pockets that may form around the roots. Lightly pack the soil around the plant to stabilize it.
Add a 1-inch layer of mulch over the root zone. Leave a 1-inch gap between the rose bush trunk and the mulch so the damp mulch will not cause mildew problems on the rose bush stem.
