Hi gibsongirl, This might not be the orthordox method, but it works for me. When I plant my roses I always use a liquid seawed/fish fertilizer from the time I plant, I use a reduced rate so it is in the soil as the plant takes hold, once the new root shoots start they can uptake the food in the soil. So every time I water I just add a small amount to the water can. Hope this helps.

Are these bands or potted plants? I don't give anything except water for most of the first year. If you must, apply at half strength to the soil. Nothing on the leaves.

I only water new first year rose plants also...

I use an old Miracle Gro dispenser and mix in fish emulsion with the water soluble fertilizer. I then hook up a hose to the end of the dispenser and attach that hose to an oscillating sprinkler. This has produced great results for me in the past.

Good idea Adrian!
