In San Diego, the Rose Society maintains the rose gardens in Balboa Park. Every January they hold pruning demonstrations in the park, open to anyone, which is an excellent way to learn about proper pruning procedures. They also have helpful guides for year-around rose care on their website, free to anyone.

I have my 16 rose bushes in raised beds due to poor soil in my yard, and use drip irrigation for them. I feed with Ada Perry’s Magic Formula (available at Walter Anderson Nurseries in San Diego) which I apply twice annually: once as soon as new growth starts after pruning in late January, and once again in July. I do a light summer prune in August and that is it, except for deadheading at least weekly throughout the flowering season. I am fortunate that I have had, in 12 years, no problems with diseases or major insect problems. I have used ladybugs to combat aphids (successfully) on two occasions in the spring. My roses are very close to my tomatoes, so I want to avoid use of any potentially toxic sprays or pesticides.
