Laguna Once-A-Year Fertilizer Spike, Aquatic Plant - 3-Pack

After using these spikes for several years, the results have been consistent and positive.

Unlike tab fertilizer needing once a month application, these spikes are slow release once a year application.

I purchased and used these for some water lilies that I had also purchased here on Amazon.

Note that the 3-pack contains the regular sized spikes, and the 6-pack (also sold here on Amazon) contains the Minis. For a one or two gallon pot, Laguna/Hagen recommends one REGULAR spike with a change frequency of one year.

Also, note that each individual spike is shipped with a protective clear plastic sleeve that MUST be removed (use a razor blade) before use. This plastic sleeve is NOT a component of the time-release feature, and must be removed (as confirmed by my phone call to Laguna's customer support line).

Since I just planted the water lilies, I cannot yet comment on the efficacy of the spikes -but assuming they work, this will be much more convenient than monthly feedings.
