The new shoots on my rose bush are limp and wilting. The rest of the shrub looks healthy, and it has had plenty of water. What is causing this and what can I do to fix it?

There's a disease (Phytophthora megasperma) that causes wilt when roses are planted in poorly drained areas. The stems near the soil surface become water-soaked, dark green, and finally dark brown. New shoots wilt and die. Some cultivars are more susceptible than others. Check the drainage of the soil -- if water puddles or takes a long time to perc down to the roots of your rose bush, you may want to dig up the plant this fall and move it to a spot with better drainage.
