Fertilizer people ar eusing?

[Miami Al]

For years I used the Laguna once a year spikes, they were amazing. They've been out of stock for a year, so I presume they are discontinued. What options are out there?

The plants are in the fabric pots with pond soil. Mostly grass from a local pond, I don't fertilize them, those are fine. I do have two lillies, I'd like to feed them so they grow well.

Pondtabbs

I have used the Pondtabbs and Osmocote which I use currently. I think the Osmocote lasts better. When I used the Pondtabbs, my lillies would slow down noticeably during the summer unless fertilized again.
