Now that the first flush is almost done, will it flower again? Do I have to feed it? What about pruning? ( I've been removing dead flowers daily) Actually I have 4 bushes - one at each corner of my pergola. The one in the ground has flowered its socks off, while the three in large pots have not done nearly as well. Any advice very welcome. Here's a pic (hopefully) of the one in the ground, taken two weeks ago.
