    It sounds like you have a grub or nematode of some kind in the roots of the plants. On the stunted ones, try gently lifting the roots and examining them for unusual root growth (knobby or enlarged roots) which would indicate nematodes or grubs, worm-like pests that are normally brown or gray in color. These pests would cause that kind of growth.

    If you have sparse blooms, it is most likely from a lack of sunlight or a lack of fertilizer. Have the soil tested and if the soil shows no deficiencies, consider ways to get the bush a little more light.

    Those dry sticks have to come out. They are likely making it difficult for other stems to grow in properly.

    Since it is not blooming well to begin with, I would recommend rejuvenation pruning. It should be done ASAP (it is suppose to be done in late winter or early spring). Rejuvenation is basically cutting the plant off a few inches above the ground. It likely will not bloom this year, but as you can use something heavier to remove those woody stems, it will get rid of the dead growth that is hurting the plant. The following years, it should return to its former glory.

    Yes, you can remove the dead growth and also the spent blooms.

    In the spring, cut off the dead wood on the shrub and you should be fine.
