Yellow Leaves on Butterfly Bush

Q: My butterfly bush has yellow leaves and is growing very slowly.  What can I do for it?  I doubt that it will bloom this summer.  Jan - Nevada
A: Things were blooming late this year because of the harsh winter.  Fertilize with 10-10-10 or 10-15-20 around the butterfly bush.  You could also use Miracle-Gro Shake N Feed to fertilize.
