A Guide to Pruning Roses

It's that time of year again! March is the time to prune your roses. Pruning roses leads to larger flowers, longer stems (important if you enjoy cutting your roses to enjoy in arrangements!) and all around better looking bushes. Here are a few rules that will have you pruning your roses like a pro in no time!

Rule #1: All roses need to be pruned. This is a must if you want healthy plants and lots of flowers. Unpruned bushes quickly become overgrown and messy looking.

Rule #2: Always use the proper tools for the job. Hand shears are good for cutting canes up to 1/2 inch in diameter. For larger stems, use two-handed ones or a small handsaw. Be sure to store your pruning tools away from temperature extremes and moisture to prevent rust and cracked handles. Also be sure to make sure your tools are sharp. Dull blades damage canes, which can lead to disease. A pair of gloves to protect against thorns is also a must.

Rule #3: Don't do any heavy pruning on own-root roses until they have become established, usually after two to three years. Grafted roses can be pruned after the first growing season.

Rule #4: Angle your cuts at a 45-degree angle, about 1/4 inch above a strong, outward-facing bud. This will keep new stems from growing into the center of the plant, leading to a fuller, more compact, and more attractive bush. It also opens up the bush to more air and sunlight. Good air circulation is crucial for disease prevention.

Rule #5: For most roses, pruning should take place in the spring before new growth begins. (The exception to this rule is for roses that bloom on old wood, like many climbers and once-flowering roses.) Start by removing any dead canes and stems on live canes. Next, cut away any weak, spindly growth and any stems that will eventually cause crowding.
