Rose Needs During and After Heat of Summer: August 2019 was the second hottest August in Las Vegas as temperatures hit the triple digits. Roses use up a lot of their resources dealing with the stress heat brings to plants and so it is time to replenish those resources. Take a look at your rose canes and stems. Some will be black and hopefully some will be green. Adding 1/4 to 1/3 cup Epsom Salt will help the bush to set new canes.
Pruning: The dead canes and branches can be pruned to the base of the plant. As the temperature becomes cooler cut the top growth by 1/3 to stimulate new growth. Sharpen your pruning shears and remember to sanitize the blades between bushes to eliminate any disease if present.
Fertilizing: Roses do well when adding fertilizer, especially during the year at intervals. In September you can add a balanced fertilizer such as 10-10-10 or your regular brand and soil additives, 1 cup soil sulfur and ½ cup superphosphate. For larger blooms add a soluble fertilizer every two weeks. When done sit back and enjoy the fall blooms.
Sun and Shading: Roses as most plants need 6-8 hours of morning sun. If your roses face south or west and get afternoon sun provide some shade. Shade can be provided with shade cloth, trees/shrubs, and or umbrellas.
Watering: Roses like water. If watered with an irrigation system September 1 starts the 3 days a week schedule. Adding wood mulch helps retain moisture in the soil. When in doubt about whether roses need watering, use a moisture meter to find out.
Now that you have done all this, sit back and enjoy roses’ second bloom this fall.

Come and join Master Gardener Lori Evans and learn how to help your garden survive the winter. Register at (Winter Garden).

Create a Native Flower Wash in Your Yard. Master Gardener Gail Brandys will share a PowerPoint presentation on how she created a Native Flower Wash in her front yard. She took dozens of photos of the process from start to finish of this two-year project. It was designed to provide some color and interest (to an area of the yard that was just gravel and weeds and no irrigation system) and to attract local wildlife. Step by step details will be provided from design to planting to enjoying and then collecting seeds and cutting back for the winter. Also, a discussion of future plans for improving the wash even further will be included. Register at (Native Flower).
