WATERING
It is important to water thoroughly and deeply for roses to thrive. Inadequate water slows or halts growth or bloom. While is important to water roses, it is also important to not over water them. Much depends on the climate and the seasonal availability of water. It is best to check the soil before watering. Moisture meters can help you decide whether it is necessary to water. Interestingly, older and bigger plants need more water than smaller plants. However, you will need to water newer plants more frequently that older plants.

Basin flooding or a drip irrigation system is the preferable way to water roses in the Pacific Northwest. Wet leaves, stems, and flowers can be a breeding ground for disease and insects.

FERTILIZING
Fertilize new plants about a month after planting. For established roses, fertilize them as soon as new growth appears in early spring. Regular applications of liquid fertilizer approximately every two weeks is beneficial to roses. Granular fertilizers should be applied every four to six weeks. It is best to use fertilizer that is specific to roses.

WINTER CARE
Roses need added winter protection below 20-25 degrees. Roses should not be planted in locations that will expose them to direct cold winter winds. Mulch at least 10 inches over the crown of the plant. Cut back extremely.
