In spring, give the plants a feed with chicken manure, before mulching well which will help to retain moisture and keep weeds at bay. When newly planted, water in dry weather, but once they are fruiting and ripening hold off on watering because this can cause the fruit to split.
Finally, when they are shiny and firm, they can be harvested. Usually this is between June and September. In addition, be sure to harvest them as whole trusses rather than picking individual berries on a dry day.
