To water or not to water? That is the question when it comes to roses. But before you reach for the hose, there are a few things to consider.
First and foremost, roses require consistent moisture in order to thrive. So unless there has been ample rainfall, watering every day may be necessary. However, too much water can be just as detrimental as too little.
The key is to ensure that the soil around your rose bushes remains moist without becoming saturated. Rule of thumb: for most climates and soils, deep watering once a week is sufficient for established rose plants.
In hot weather or sandy soil conditions, daily watering may be required, but make sure the depth of the water penetrates below shallow root zones. During cool or cloudy weather in fall and winter, cut back on daily watering since evaporation rates decrease sharply.
Another important factor is the time of day you choose to water your roses. While early mornings bring dew, dampness, fungal growths, and leaves rot due to extended night dampness, avoid watering after dark. Instead, time your irrigation for early morning hours or late afternoon/evening times before sunset.
But really, the best way to determine if your roses need watering is simply by checking the soil moisture level. Stick your finger into the top couple of inches of soil. If it’s dry, then give them a good soak. Having said that, your roses would truly appreciate an inch of compost being added periodically.
Keeping these basic tips in mind will help ensure your rose bushes remain healthy and vibrant all season long without being overwatered or thirsty.
