Roses increase the visual value of any garden regardless of their color, shape or size, but no rose draws as much attention as a purple rose. These roses come in different shades of color ranging from pale to deep purple, and range in size from small tea roses to the large floribunda types. Purple rose hybrids are hardy roses that can withstand the presence of pests such as aphids and spider mites, and yet require no more care or attention then standard rose breeds.
Use a small shovel to dig a hole for planting in an area that receives full sun for at least eight hours per day. Ensure the planting hole is large enough to accommodate the root ball of the rose.
Water the purple rosebush well after planting using a soaker hose. Water until the soil is moist to the touch, but not soaked. Water the rose weekly or as needed to maintain good moisture content. The soil around the base of the rose should always be moist to the touch.
Add a layer of mulch around the base of the rose to help hold moisture close to the roots of the rose plant and to help keep down the presence of weeds.
Feed the purple rose plant using rose food from your local garden specialty store or nursery, after planting, and once per month until the first frost of winter.
Lightly prune the purple rose plant throughout the growing season by pinching off dead blooms to encourage new growth.
Prune the purple rose heavily after the first frost of winter. Remove any long, scraggly growth from the rose. Do away with any dead or canes, and cut back all the growth about 3 to 4 inches to encourage thicker, new growth the next growing season. Complete the pruning using sharp pruning shears to make smooth, even cuts.
