Watching from 7 minutes and 22 seconds on in this video

there is a brief discussion of an experiment showing the results of using no fertilizer, slow/continuous release fertilizer and finally a water soluble fertilizer.

For sure it isn't a rigorous use of the scientific method but It did get me thinking as to my fertilizing routine:

I have used this Canadian made fertilizer 'forever' for our container annuals

I checked the application instructions and as I had thought, there is no mention of "dissolving" this product in water but mixing it into the soil pre planting and then 'scratching' into the surface of the soil post planting, once a month, through the growing season. So a slow release food.

I noticed this year that I had a few pots that had still not not done the usual growth spurt and here it was late July into August :(.

And so I decided to use the "fast food" of fertilizer i.e.

And after two applications of this water soluble food (about 8 days apart) I have been impressed with what I have seen in our containers.

I'd love to know what my gardening friends here do regarding feeding your potted annuals for the season. What product? How often? Etc
