There is very little that is as good for your soil as leaf-mould - worth its weight in gold to the gardener. It really improves the structure and water retention of the soil. We rake up every fallen leaf we can lay our rake on each autumn to make leafmould
For fertiliser I use Fish, Blood and Bone which is an organic slow release fertiliser and chicken manure pellets. I apply these twice a year.
I also use specialist Clematis feed (as directed on the packs) for the clematis and other climbers as they are such hungry feeders, and also tomato feed, not just for the tomatoes but also for pots of bedding plants and other flowering plants such as roses etc. Tomatoes only get fed once a month or so, but pots of bedding plants get fed once a week.
It's important to make sure that granular/dry fertilisers are watered in well as otherwise they do no good at all.
In the summer I water pots and containers just the same, whether or not there's been any rain, because as you say, the foliage sheds most of the rain. I usually water my largest containers about twice a week, giving them a really good soaking, but small pots need watering every day in hot weather.
