The last month for fruit pruning and keep picking to encourage re-growth, proecting autumn raspberries with netting.
You will have a great month harvesting all kinds of vegetables too - Pick beans regularly.
Weather dependent you will probably be required to water your crops daily - even if you get a shower, it isn't always enough to feed thirsty plants! If you're planning a summer holiday perhaps you can share watering duties with a plot neighbour!
Keep your eye out for pests and disease and treat where necessary and of course there is always a bit of weeding!
