rosebush died quickly (2 weeks from live to dead)
Sorry for the long post, this is my first time growing roses. I'll give a little history first then talk about the problem. I moved into this house in Feb 2007. Nothing in the yard had been taken care of for 2.5 years prior to me moving in. Prior to that 2.5 year period things had been very well cared for on the property. I learned this from the neighbors.
Many things were doing EXTREMELY bad to start off in the spring. I spent last spring/summer/fall carefully working to care for the rhododendrons, azaleas, Japanese maples, and roses to bring them back to good health.
Everything has taken off real well. This year there is new growth and great blooms on all of the plants that I have worked with. There was a lot of reading and research done on the web. I don't follow a totally organic process for the garden, but generally try to if I see there is a successful organic method for something.
For the roses, I have 4 bushes total. There were 3 when we moved in Feb of last year. Last spring I noticed a small shoot coming up in between 2 of the roses. I took care of it and it is now about 1.5 feet tall and has bloomed this year. Last year the largest bush had 1 bloom and the smallest of the original bushes bush had 1 bloom. That was it. Of the original 3 bushes, the 2 that each had one bloom last year exploded this year. They were blooming, I deadheaded and they continued to bloom. Even the bush that didn't bloom last year bloomed nicely this year.
My problem is that the largest bush has suddenly died. I last was out working with the bush 2 weeks ago. I had taken care of the bush and deadheaded. There were new buds that hadn't yet opened. It has rained a couple times here in the past 2 weeks so I didn't go around the side of the house to water or check things out. This weekend I went over and the rose is dead. All the leaves have fallen off and are on the ground around the bush. A few dead leaves are still stuck to the bush. The stems seem to be dying from the top down. There is still a good deal of green in the stems, but I see them browning at the top and it seems to be working its way down to the bottom. There are no leaves left on it at all. The only time I have ever seen anything die this fast was when weed killer was sprayed on it (no, I didn't spray it with weed killer).
The other roses are all fine, even the new 1.5 foot shoot that is next to it. I am worried that there was something specific that killed it and may hit my other roses.
The leaves that fell off were whole, not eaten. I didn't see any bugs on it or on any of the other roses. There were aphids earlier this year which I did spray all the bushes down with some bug killer that was safe for roses, but that was around 6 weeks ago or so.
Anyone have any ideas?
