My new 'Miss kim' Lilac bush, planted last fall, as a twig is now looking very-very shabby. In spring it showed great promise but mid to late summer took a turn for the worse. Yellow to brown spots and speckles developed on leaves and now leaf edges tattered, torn and brown. Stem is also speckled with a white scab-like texture, very small bumps, but maybe thats its normal constitution---I'm not sure... my new magnollia tree also has this texture on its'stem.

To some extent what you are describing on the foliage could be related to the soil conditions and/or lack of soil moisture, but there might also be a pest or disease problem at work. Unfortunately, I am also not able to tell you if the bumps you are seeing on the bark are normal, or not, based on your description. (They might be scale insects which would need to be treated.) For this reason I would strongly suggest you consult with your retailer and/or county extension for a more specific diagnosis of the problem(s). If it is something that requires treatment, your county extension will have the most up to date information on what to use and how/when is best to apply it. Good luck with your plants!
