Answer: We have had an unusual spring and it is possible that the weather has delayed blooming. It is also possible that the organic matter content, nutrient balance (and possibly pH) in the soil have changed over the years and it needs to be reworked or adjusted. I would suggest you run some basic soil tests and see. Your county extension should be able to help you with the tests and interpreting the results. Good luck with your roses!
