I have a hedge consisting of some 150 plants. It suffers from yellowing of leaves but has plenty of flowers. Several suffer with "small leaves" and any newly planted shrubs fail to develop (ie: stay spindly, and poor leaf growth). What fertilizer do you recommend?

I would actually recommend that you have your soil tested. This would be the best way to find out for certain what, if any, nutrients might be missing that could be causing the problem. Then you can find a suitable fertilizer based on that.
