How To Prune and Train Roses

Every gardener wants beautiful, flourishing roses in their gardens, but how do you achieve that? The answer is simple: You prune and train your rose bushes. The techniques in this article will help promote better rose growth, increase flower production, and create an attractive shape for your plants. Let’s explore the step-by-step process of pruning and training roses. In the video above, This Old House landscape contractor Roger Cook prunes a rose bush and installs a support structure for climbing roses.

What Is Rose Pruning?

Pruning is an element of rose care that involves removing dead, diseased, or weak growth to encourage healthy development. When done correctly, pruning can improve the overall health and appearance of your rose bushes. By eliminating parts that hinder growth, you make room for new, vibrant flowers and robust canes—the stems that support the plant and produce flowers.

When To Prune Roses

Prune at the right time so you don’t accidentally remove flower buds and you optimize your roses’ blooming season. If you’re unsure of the type of rose bush you have, consult a local nursery or gardening expert. The best time to prune roses depends on the type of rose and your climate. Here are a few examples:

• Spring-flowering roses: Prune immediately after flowering.
• Repeat-flowering roses: Prune in late winter or early spring.
• Climbing roses: Prune in late winter before new growth begins.

Tools for Pruning Roses

Before you start pruning, gather the following tools:

• Bypass pruning shears
• Heavy-duty gloves
• Long-handled loppers
• Long-sleeved shirt
• Pruning saw (for thicker branches)

Use clean, sharp tools to make clean cuts and prevent the spread of disease. Dirty tools can transfer pests and illnesses between plants, so sterilize your tools before use.

Pruning Techniques for Roses

Follow these steps to prune your roses effectively.

Removing Dead and Weak Growth

Begin by inspecting your rose bush for old, dead, or weak branches. These can be identified by their lack of foliage, poor color, or minimal flower production. Using a pruning saw or bypass pruners, cut these branches at the base of the plant. This allows energy to be redirected to healthier parts of the bush.

Deadheading Roses

Deadheading is the process of removing faded flowers to encourage more blooms. To deadhead, locate a faded flower on the rose bush. Cut about 1/4 inch above a leaf stem with bypass pruners. Make sure the cut is at a 45-degree angle to promote water runoff.

Deadheading throughout the growing season will help maintain your plant’s appearance and encourage continuous blooming. This also prevents the plant from directing energy into seed production, which can be taxing for the rose bush.

Shaping the Rose Bush

Shaping your roses improves their looks and ensures sunlight and air can penetrate the canopy, reducing the risk of fungal diseases. After removing dead growth and deadheading, follow these steps to shape your bush:

1. Cut back the remaining canes by about 1/3 of their length.
2. Make cuts at a 45-degree angle just above an outward-facing bud.
3. Remove any crossing or rubbing branches to improve air circulation.
4. Thin out the center of the bush to allow more light and air to reach the inner branches.

Training Climbing Roses

Training climbing roses helps create an attractive display and promotes better flowering. This process involves guiding the plant’s growth along a support structure.

Installing a Support Structure

To train climbing roses, you’ll need a suitable support structure. In the video, Cook demonstrates how to install a horizontal support using cedar split-rail fence sections. Cedar split-rail fences provide excellent support and add rustic charm to your garden. These are the steps Cook follows:

1. Dig 3-foot-deep holes for fence posts on either side of the rose bush.
2. Set posts in the holes and confirm that they’re level.
3. Attach horizontal rails to the posts using a small sledgehammer.
4. Backfill around the fence posts with soil.

Tying Rose Canes to the Support

Once your support structure is in place, gently tie the rose canes to the horizontal rails. Use soft, flexible material like jute twine to avoid damaging the canes. Space ties evenly along the cane for proper support. Tie them loosely to allow for growth and movement.

Training roses horizontally encourages the growth of lateral shoots, which produce more flowers. This method of training will encourage your climbing roses to develop a full, lush appearance, with blooms distributed evenly across the plant.

Ongoing Care for Pruned and Trained Roses

After pruning and training your roses, continue to care for them to achieve healthy growth and abundant blooms. 

Soil Preparation and Fertilization

Well-prepared soil provides the necessary nutrients for your roses to thrive. Fertilizing in the right proportions encourages strong root development. Prepare the soil around your rose bush by following these steps:

1. Remove weeds from a 3-foot circle around the base of the plant.
2. Apply a balanced fertilizer to the soil. Cook uses a fertilizer with a 5-10-5 formula, or five parts nitrogen, 10 parts potassium, and five pasts potash.
3. Gently rake the fertilizer into the top 2–3 inches of soil.

Mulching

Apply a 2-inch layer of mulch around the base of the rose bush to suppress weed growth, retain soil moisture, and regulate soil temperature. Cypress bark mulch is an excellent choice for roses, as Cook demonstrates in the video. Mulching conserves moisture and adds organic matter to the soil as it breaks down. This continual source of organic material helps maintain soil structure and fertility.

Watering

Roses prefer a consistent watering schedule that keeps the soil moist but not waterlogged. Early morning watering allows time for any excess moisture on foliage to evaporate, reducing the likelihood of disease.

Provide 1–2 inches of water per week. Water deeply and less frequently to encourage deep root growth. Avoid wetting the foliage to prevent fungal diseases.

Common Problems and Solutions

Rose bushes, like most plants, can be prone to pests, diseases, and nutrient deficiencies. Here’s how to address these problems.

• Pests: Aphids, spider mites, and Japanese beetles are frequent pests on roses. Regularly inspect your plants, and if you notice an infestation, use insecticidal soap or neem oil to treat the affected areas.
• Diseases: Fungal diseases like black spot, powdery mildew, and rust are common. Ensure proper air circulation, avoid over-watering, and remove affected leaves to keep these diseases at bay. Planting disease-resistant rose varieties can help.
• Nutrient deficiencies: Yellowing leaves can indicate a nutrient deficiency. Conduct a soil test to determine the missing nutrients and amend the soil accordingly. Balanced fertilizers and organic compost can replenish essential nutrients.

Roses: Seasonal Care Tips

Roses require different care techniques as the seasons change. By adapting your practices, you can have healthy roses year-round.

• Spring: As new growth begins, it’s time for a thorough pruning. Apply a balanced fertilizer and start inspecting for early signs of pests and diseases. Mulch the base to retain moisture as the weather warms.
• Summer: Water your rose bushes regularly, deadhead spent blooms, and keep an eye out for pests. Applying a slow-release fertilizer can support continuous blooming.
• Fall: In regions with harsh winters, start preparing your roses for dormancy. Reduce watering, stop fertilizing, and mulch heavily around the base to protect the roots from freezing.
• Winter: Pruning should be minimal in winter. Focus on preventing damage from heavy snow and ice. Covering the rose bush with burlap can offer protection in extremely cold climates.

Pruning and training roses are the key to healthy, beautiful rose bushes. By following these techniques and providing proper ongoing care, you can enjoy abundant blooms and attractive plants throughout the growing season.
