What is SUPERthrive® Plant Vitamin Solution with Kelp?

SUPERthrive® Plant Vitamin Solution with Kelp is a vitamin supplement for plants, not a fertilizer. It combines essential vitamins with kelp, a natural source of growth hormones, to help plants recover from stress, strengthen roots, and boost overall growth. Use it alongside your regular fertilizer or plant food for best results.

How much of the mixed solution should I pour on my plants?

Once mixed, water your plants as you normally would — just enough to moisten the soil without soaking it.

  • Larger plants (trees, shrubs, bushes): Apply enough to wet the root zone, especially if the soil is dry.
  • Smaller plants (flowers, herbs, or containers): Use less — stop when the soil feels evenly damp.

Tip: SUPERthrive® Plant Vitamin Solution with Kelp enhances regular watering; it doesn’t replace it. 

Please remember to follow the instructions printed on the product's label for the best results.

Can I use SUPERthrive® Plant Vitamin Solution with Kelp with my regular fertilizer?
