5 Ways to Care for Roses in Summer
1. Depending on your rose type, you may need to lightly prune your roses after the first bloom is over.
Older varieties of shrub roses need a light summer prune once their first flush of flowers fades. This is not like the major cutting back done in late winter or early spring. It's a light prune to remove spent flowers and encourage leafy, new growth.
However, for newer rose varieties like Grace N' Grit™ and Nitty Gritty™, no pruning or deadheading is needed. Only prune these roses for size and shape if you desire. Always remove dead stems and limbs no matter the rose variety.
If you have roses that require summer pruning, here are a few tips:
- Don’t just deadhead and clip spent blooms; cut flowering stems back to two or three sets of leaves. Think of it like cutting roses for a bouquet and you’ll get the length right.
- Expect to see your plants back in full flower about four weeks from pruning.
- Stop pruning 3 to 4 weeks before the first hard frost to discourage new growth that may be damaged by the cold.
2. Feed your roses
No matter the type of rose you're caring for, you can keep it healthy by feeding it a well-balanced fertilizer. (Look for three numbers that are the same on the package, like "5-5-5"). Fertilizing roses is especially important if you're pruning them mid-summer because the new growth draws on the plant's energy reserves. Feed now and water as needed so plants aren't stressed.
Apply the balanced fertilizer or rose food around the base of the plant according to the directions. Follow this by a deep watering. Watch the video above for a visual guide.
3. Keep roses watered and mulched, especially in dry conditions
Whether your roses are planted in the ground or in containers, it's best to test the soil before watering. If the top 1-2" is dry, then give them a deep soak.
Create a watering well around the base of the rose. Do so by pushing soil out from around the base of the plant to form a basin, capturing water. Then, deeply soak at least once a week while roses are in growth and flower. Make sure the soil around your roses is topped with a layer of mulch (about 2 inches deep). Also, pulled back from the base of the plant.
Improved, own-root roses like Grace N' Grit™ and Nitty Gritty™ are actually quite tolerant of dry conditions once established. You may not need to do much irrigation after their first year in the ground.
Roses in containers will need to be watered more often, especially in dry, hot weather. Roses that are planted in containers look fabulous but do require more watering. This is because the soil dries more quickly than when planted in the ground.
4. Make a clean routine
Half the battle with keeping roses healthy, especially in summer, is stopping trouble in its tracks. Start with roses that are more disease resistant such as Grace N’ Grit™, Nitty Gritty™, or Seaside Swirl™ rugosas. Really any other notable varieties that have been bred for increased disease resistance. Grace N' Grit™ and Nitty Gritty™ roses have shown high resistance to disease in our extensive trials across the country.
To keep your older more disease-prone varieties healthy, try these tips:
- Clean up the debris such as trimmings, spent blooms, and dead leaves from the area under and around the plant. These are a breeding ground for fungal diseases such as black spot and powdery mildew.
- Make sure pruners are clean before starting to prune. Be sure to clean them when moving from plant to plant.
5. Stay ahead of trouble
While keeping plants healthy can reduce problems, it doesn’t make them immune from insects. Stay ahead of pest infestations by catching early and treating with the appropriate method. Take a tip from Monrovia's plant health team. Keep pests at bay with beneficial insects such as aphid-eating ladybugs (their larvae actually do most of the aphid eating). Get to know and encourage beneficial insects in your garden. Avoid the use of pesticides to avoid harming these natural allies.
Always start with the least harmful method of control and only “escalate” if you’re not getting results. Plant problems and solutions are often regionally specific. That's why we recommend consulting your local nursery or extension office for help identifying pests and selecting remedies.
