Why do my Knock Out roses look like they are dying?

Answered by Tom Adger

I’ve had a similar experience with my Knock Out roses looking like they were dying, so I understand your concern. There can be a few reasons why this might be happening. One common issue is drought and high heat. These roses are generally quite hardy, but they can struggle in extreme weather conditions. During drought or periods of high heat, the roses may not be getting enough water, causing them to wilt and develop brown spots.

In addition to the lack of water, the plants may also be dropping their old leaves. This is a natural process as the roses redirect their energy towards new growth. It can be alarming to see the old leaves dropping, but it’s usually a sign that the plant is prioritizing its resources.

To address this issue, it’s important to ensure that the roses are getting enough water. If your garden is experiencing a prolonged period without rain, consider irrigating the roses on a weekly basis. This will help keep the soil moist and provide the roses with the hydration they need. You can use a drip irrigation system or a soaker hose to water the plants deeply and efficiently.

Another helpful tip is to mulch around the base of the roses. Mulch helps retain moisture in the soil and also helps regulate soil temperature. This can be particularly beneficial during hot and dry periods.

It’s also worth checking the roses for any signs of pests or diseases. Insects like aphids or diseases like black spot can cause damage to the leaves and make the plants look like they’re dying. If you notice any signs of pests or diseases, you can treat the roses with appropriate insecticides or fungicides.

It’s important to provide your Knock Out roses with the care they need, especially during challenging weather conditions. Regular watering, mulching, and keeping an eye out for pests and diseases can help ensure the health and vitality of your roses. With proper care, they should bounce back and continue to provide beautiful blooms.
