I have an escalonia hedge [80 shrubs] planted about twenty years ago in a heavy clay soil. It was enormous when we decided that it needed to be cut back - about five or six years ago, and it took a few years to get it to grow back up to a reasonable, maintainable hedge size. However, the blossom has been a rare occurance since. We've bought a number of feeds from the garden centre but to no avail. Can anyone suggest what I should do to get this beautiful hedge in healthy bloom again? Thanks for your time.
