What can I use to give my hanging baskets a boost?

What in particular is bothersome? Could a granular fertilizer or fish emulsion help? I also use soil moist in all my baskets and planters

I use organic fertilizers. I also like to use tea bags, we talk about it in this post: https://chemistrycachet.com/free-potted-plant-food/

I use Miracle Grow...

Epsom salt.

Time release fertilizer and enough water

Fertilizer stakes work great, you just push them in and they time release.

Miracle grow!
