I planted these double knock out rose trees about two weeks ago. At first, they looked great. I made sure to water, water, water – since it has been very hot lately. Now, they look sickly, the leaves are rapidly turning yellow and the roses (that were already in bloom) have all died.


What is happening to these poor guys and how do I reverse it?

No! I went against my better judgement. Do you have a particular fertilizer that you would suggest for roses? I searched online, but there are so many options! I don't know what the good stuff is. :)

If you plant more roses dig some rotted horse manure (if available) into the planting hole but avoid major contact with the roots as it will burn them. Other than that chicken manure pellets have the same effect and can also be used as a general fertiliser after planting. I feed my roses two or three times during the growing season, the last feed in July so that it gives the roses a chance to settle down before their dormant season over winter. There are various rose foods available but I sprinkle Fish, blood and bone on the surface around the base of the rose then water it in. The same applies to the chicken pellets. :)

Hello Leila. I have only recently begun using this forum and I am already reconizing some familiar friends. Now then to your roses. Of course the rose season is long over for 2018 and we are soon to be seeing new buds on most plants. In your original post, you say that you planted these two roses a couple of weeks ago, that was then. I suspect they were container grown/supplied rather than bare rooted. You also mention that you feel you may have overdone it with watering. So in your area, the ground was very dry, so watering would not in my opinion affect them, as the water would have soaked away fast.
As a general rule of thumb, plants, trees & shrubs, container grown or bare root need a good soak prior to planting. This enables the body of the plant to quench it's thirst. In practice digging a hole and watering it is good but the water is alread soaking away from wtere the plant is going to sit. Enough about watering except, try and water in the cool of the day.

Most plants will undergo some set back when being planted. The leaves are usually the first indicators that there may be problems. Hence the yellowing etc. Sadly once the leaves pick up the signal that not is all well, the plant will automatically put up the shutters and prepare to close down. Don't waste money on chemical sprays etc.

Now on the brink of a new season. Give the plants a going over. Cut out Once new growth shows any weak, damage growth. Then prune to shape.
