Gardening;fertilizing my hydrangeas for BIG blooms / quick thrift trip

We're taking a little break from gardening since the weather is not cooperating Not much you can do in the rain All the flowers that I bought are hiding in the garage So let's pop over to value Village let's see what they have Rocco wants to come along And then I really need to get on fertilizing my hydrangeas. I bought Holly tone. I hear all good things about this product, which is not readily available here in Canada. I've ordered it on Amazon waiting for it to arrive.
