Roses - first year care - Knowledgebase Question

I just bought several Rose bushes at Home Depot. Rosa Knockout and two other types. I followed the instructions for location, planting, watering, but was wondering if I need to do any other maintenance in this first year to be succesful (is food needed?)

Flower Carpet roses will grow in any sunny location. They need no special care or feeding aside from frequent watering. They?re hardy in North American Zones 5 through 10, from Florida to Maine, making them a hands-down choice for gardeners across the country who want a hardy, beautiful rose for their gardens.

Shrub roses should be fed 3 times a year. Many rose lovers come up with all sorts of "secret" feeding formulas. The truth is, however, that most hardy shrub roses grow beautifully when fertilized three times a year: spring, mid-summer, and early fall. Use a balanced fertilizer such as 16-8-8. Organic products such as home made compost also work well. For the last feeding in fall I often use a high phosphorus product such as 12-24-12 or 10-20-10. A low nitrogen and high phosphorous blend encourages less vigorous growth while increasing winter hardiness.

Best wishes with your new roses!
