|You can use a foliar fertilizer such as Miracle Gro or you can move the mulch and broadcast a time release granular fertilizer and then replace the mulch. One application in spring of a granualar fertilizer should be just fine; a liquid fertilizer should be applied every 4-6 weeks during the growing season. Best wishes with your Knock Out Roses!
