How to Prune Overgrown Miniature Roses
Miniature roses offer delicate blooms of color, often covering the entire plant during early summer and filling the air with the sweet scent of roses. When a miniature rose bush matures, it sends out new shoots farther from its base, causing the delicate boughs to drop downward and reducing the blooms in the center of the plant. If you have an overgrown miniature rose bush, follow some easy techniques for pruning it back and producing a compact blooming habit. Does this Spark an idea?

1
Perform periodic pruning during the height of the bloom season on miniature roses to encourage new blooms. With a sharp pair of garden shears, cut the spent blooms from the rose bush. On miniature roses, the blooms cluster on the end of one rose spray, containing up to 30 roses at a time. When the blooms die, the rose bush expends energy on making the little seedpods known as rose hips.

Nip off an entire cluster if 90 percent of the blooms are spent. Cut the main support stem just below the uppermost common node before the branches spread outward from the stem.

Use very sharp nippers to keep from tearing the green stem and inviting bacteria and fungus growth. With the spent blooms gone, the rose bush will send its energy into the production of new flower buds.

Save major pruning of a miniature rose until late in the fall when the rose is beginning to go dormant or in the spring before the green appears in the stems. Major trimming to a blooming rose bush may shock the plant and stunt its flower production. The general rule when pruning roses is to never cut off more than 1/4 of a green stem.

Prune a dormant overgrown miniature rose by snipping off the end of the stem just to the outside of a stem node. When the plant begins to grow, it will send out new branches below that node, creating a compact shape. When dormant, you can prune a miniature rose back to within 2 feet of the base. However, prune a climbing miniature rose by cutting back the side stems only to encourage an upward growth pattern. The same holds true for miniature rambling roses.

6
Remove all dead or damaged rose stems in the early spring as soon as the stems begin to show some green coloring. Dead stems drain the plant of its energy as it continues to send energy to the damaged area.
-
7
Try using dormant oil spray when pruning your overgrown miniature roses in late winter. Although this is optional, the best time to apply dormant oil is just after you’ve pruned the bush (see Resources).

Tips & Warnings
Sharpen any garden shears or nippers before pruning. The cleaner the cut, the less likely it is that the rose will develop a fungus or bacteria problem.
