I trimmed my hydrangaes last summer in the beginning of August as told so I would not cut off next years flowers. I did not get any blooms this summer but lots of foliage. What can I do for next summers flowers?

Most hydrangeas bloom on new growth which develops on old growth. Pruning in August won't affect the flowering next year, but hydrangeas are typically pruned in very early spring, just as new growth begins. As long as there is old wood on which new flowering shoots can grow each year, you should get flowers. If your hydrangea regularly freezes down to ground level, you may not get flowers from it. If this is the case you might want to consider replacing it with one of the varieties that will bloom on new wood. Endless Summer is a good choice. Aside from that, hydrangeas need about 4 hours of morning sun in order to bloom well. Hope this helps!
