I only use BFB in Spring, on the veg plot and around herbaceous plants. The blood gives a quick dose of nitrogen, the Fish meal feed feeds through the summer, the bonemeal breaks down slowly and feeds roots and gives a strong plant for winter. Many plants, if you feed late in the season, you get soft growth which is more prone to fungal rots over the winter and frost damage.
Plants in pots need feeding with a soluble fertiliser like phostrogen or they become nutrient deficient very quickly. You could use osmocote which will last for 12 weeks.
