March is the start of rose planting season, which culminates in June. The newest varieties are found early in March. Plant them while available.
Visit my local guide: How to Plant Roses.
Six rose types are planted locally: Hybrid Tea, Floribunda, Grandiflora, Climbing, Carpet and Shrub roses. March is when each is pruned, cleaned and fertilized. Several columns are dedicated to cover each variety. This issue is dedicated to the hardiest of roses, shrubs.
Shrub roses are the easiest to care for and bloom the longest with minor disease and insect issues. The newest varieties of Easy Elegant and Knock Out roses have large, fragrant flowers. At first glance, they resemble a long-stem Hybrid Tea Rose.
Grown in pots, raised beds or directly planted in the garden, this new variety likes growing locally and March is the best season. The benefit of planting a shrub rose is the ease of care. They self-prune spent flowers and rebloom automatically for nonstop fragrance from May through October.
Upright shrub roses make bold statements in a garden because of their blooms and sprawling growth habit. However, these large shrub roses can be somewhat wild and ill-behaved in their growth and must be tamed through pruning that focuses on shaping them. Pruning is a simple process.
Start by removing any broken or diseased portion of the bush. Shrub roses should be pruned by cutting stems back to a healthy bud. After the cut, look for healthy white wood in the cut. If brown, continue to cut until you reach white wood. Make cuts at a 45-degree angle, about 1/4” inch above a bud. The goal is to remove all dead or broken canes, creating a pleasing shape that opens the interior to light and air.
Top Tips for Pruning Shrub Roses
Prune in March when new shoots begin forming on the canes.
Cut to about one-third of the desired final size. They typically triple in size after pruning.
Remove dead or damaged wood as you see it.
Remove one-third of old growth every two or three years to rejuvenate the shrub.
Rake all fallen leaves, twigs and branches away for your bush.
Apply 2-3” inches of Watters “Premium Mulch” over the root zone for longer bloom times.
Deadhead the Flowers
All roses benefit from deadheading, or pinching spent flowers. This extends the bloom period significantly.
Roses are heavy feeders and need several fertilizer applications during the growing season. We created a fantastic food that roses love called Watters All Purpose Plant Food. Feed at least three times annually in spring, again in summer, and a final application in the fall (March, July and October). Water thoroughly after each feeding.
Watering
Roses need water and appreciate being on a drip system. Remember how deep you planted the rose? Water must reach that level to get to the roots and keep the plant healthy and blooming. Water thoroughly twice a week if there is no rainfall. Set a watering schedule and adjust as dictated by the weather. Even though you may see fewer flowers during the summer, cooler weather will bring more flowers, so keep up the watering schedule. To discourage black spots and mildew, water in the morning and avoid moisture on the leaves.
Until next month, I’ll be helping gardeners plant better roses here at Watters Garden Center. QCBN
