Pruning rose bushes
Home & Garden - posted Mon., May. 7, 2012
Prune back your rose bushes after the first bloom. You can either dead-head the spent blooms or do a major cutting back to keep them tame and under control.
Cut back all weak and dead wood, as well.
Lastly, clean up all the spent or fallen leaves – especially if they suffered from black spot.
If black spot is a problem on your rose bushes, use this homemade formula: Mix one tablespoon of baking soda and a 1/4 teaspoon of dishwashing detergent in one gallon of water.
