I don't think it would burn the roots. There might be some loss of N from urea into the atmosphere as ammonia. IIRC, there is chicken manure in current RT, and this contains urea.

I tend to go by how hydrated the roses are when I apply the Rosetone. We've had fairly steady rain for the past few days, so today I just put down Rosetone, lightly mixed it into the loose soil on top, and covered it with mulch (which I was adding for the summer anyway). If it doesn't rain in the next day or two (the forecast is a bit iffy), I'll probably put my hose on a stiff spray and circle each rose a couple times to help the Rosetone sink in.

Normally I water the Rosetone in immediately after applying it. I personally don't think anything disastrous will happen if you have to wait a day or two, however.

Perhaps today just feed and water a portion of your roses, and then in a couple days, feed and water the rest. That might work. : )

I deliberately apply fertilizer when rain is NOT in the forecast and then don't water it in because our neighborhood is located adjacent to a tributary of the Chesapeake Bay (and the Bay has way too much fertilizer in it already). The dew and occasional rain showers gradually dampen it. I use Rosetone or Hollytone and the roses have not complained.

We had two inches of rain on Monday night so they were pretty well hydrated. But there is no rain in the forecast (of course!) so maybe I will wait a day or two and water in.

Thank you.

I have to water it in or my dogs will eat it. But I don't think it would hurt it not to water.

It doesn't matter with Rosetone to me. The amount of readily available nitrogen in Rosetone is fairly low, so the chance of it burning the rose period is pretty low....nonexistent in my opinion from the ridiculous amounts I use of it. Theoretically, it would be more liable to burn if it was dry and already in the soil, but this isn't really possible with rose tone as it needs the water to let it sink in to the soil anyways.

Personally, I try to put it down before it rains, because I like to have nature just do it job and it works the best then, but if it's sunny it's no big deal. I just water it in even if it's dry. I figure with such a low amount of readily available nitrogen, even if the soil is dry, the water will dilute the mixture and just mix in with the surrounding soil and the rose will enjoy the water to begin with...the added nutrients of the Rosetone are just another plus to make the rose happy.
