What fertilizer do I need to use? My mock orange has not had any flowers for 6 years. I have used 10-10-10, have "pruned" and used a fertilizer heavy on phosphate. Please help!

If you have not pruned in a while then it may be in need. Pruning can help rejuvenate the shrub and improve its overall health and blooming, as well as its appearance. You can do this once flowers have faded out by one third. As for fertilizing, it generally needs little, other than an occasional all-purpose rose-type fertilizer. If blooming still seems to be an issue following pruning, your soil may be lacking phosphorus. Add some phosphorus, such as bone meal, to the soil.
