Our take on the National Plant Network 28-oz 15-30-15 Fast Release Water-soluble Tablets All-purpose Fertilizer

These are water-soluble fertilizer tablets with a 15-30-15 nitrogen-phosphorus-potassium ratio, sold as a 50-count pack. The high phosphorus share suits flowering and fruiting plants and root development more than leafy growth. The fast-release formula feeds for up to about 14 days, so it needs reapplying more often than slow-release granules. It is a simple option for container plants and beds where you want quick, measured dosing, but it is not OMRI listed for organic growing.

Pros
  • Pre-measured tablets avoid scooping and mixing powder
  • High phosphorus ratio supports blooms and roots
  • Fast release acts quickly

  • High phosphorus ratio is a poor fit for lawns and leafy greens

Questions and answers

What does the 15-30-15 ratio mean?

How long does one application last?
The fast-release formula feeds for up to about 14 days. Plan to reapply through the growing season.
How do I use the tablets?

Is it suitable for organic gardening?
No. It is not OMRI listed, so it does not qualify for certified organic production.
Can I use it on my lawn?
It is an all-purpose plant food, but the high phosphorus ratio is not ideal for lawns, which want more nitrogen. Use it on flowers, vegetables and containers instead.
