Consulting Rosarian Tips for March:
The winds of March can be fierce and very drying. Keep checking your soil for moisture and water every couple of weeks if needed on days when the temperature will be over 40 degrees.

If you must get out in the yard and work on your roses, do nothing more than remove dead canes. It is too early to prune.

If the soil is workable you can get holes prepared for rose planting. When deciding on a location make sure the site will receive at least 6 hours of sun daily. The more sun the better. Know the mature size of the rose. Plan for proper air circulation around the plant. Look at the location; think about what shrubs, trees or other plantings that may compete with the rose roots. Dig the hole a minimum of 14 inches deep by 18 inches in diameter, the larger the hole the better. Amend soil with 1 part compost and 3 parts native soil.

March and early April are prime times to transplant roses from one location to another.  Their current dormancy will help reduce the stress of the move. Tips: Make sure the soil is moist but not soggy. Digging in soggy soil can cause compaction (bad thing). Digging up a rose in dry soil can cause the root ball to fall apart (annoying thing). Prepare the new location first. The rose will do best if it is out of the ground for the shortest time practicable. As you dig up the rose, try to maintain the root ball if possible. This can preserve the tiny root hairs, and help the rose get a better re-start. If the root ball falls apart, oh well, re-plant as a bare root rose. The rose may take longer to re-establish, but the success rate should still be good. Be sure to plant the graft or growth point at the proper level (See Growing Roses In
Colorado). Then cover with mulch, evergreen boughs, or burlap until the frosts are gone, and it is safe to turn the rose loose to grow.

IFor rose questions, contact a Consulting Rosarian in your area.
