Powder Sachet Biostimulants: Rooting Agent, Deficiency Corrector and Boosters

Quick answer: Fertinagro's powder biostimulant sachets are fast-acting, highly concentrated products for specific moments: reviving a weak plant, kick-starting rooting after transplanting, correcting a visible deficiency, or giving a final push to blooming or fruiting. They differ from a maintenance fertilizer in that they solve a specific problem rather than replacing regular feeding.

Recovery and rooting

Product When to use it
BIO Universal Turbo Revitalizer A plant that's fading and needs a boost to recover
BIO Natural Super Rooting Agent Right after transplanting or when taking cuttings
Bulb and Seed Germinator At sowing time, to trigger germination

Correctors for visible deficiencies

Boosting bloom and fruit

Practical maintenance in pots

The BIO Organic Fertilizer Tablets are a slow-release fertilizer in pelleted tablet form: they're buried next to the root and release nutrients over an extended period, without the need to dose liquids every week.

How to choose based on the situation

  • You've just transplanted or taken cuttings: Natural Super Rooting Agent.
  • The plant looks generally unwell, with no clear cause: Turbo Revitalizer or Universal Deficiency Corrector.
  • Yellow leaves with green veins: Universal Greening Agent (or Anti-Yellowing Treatment for conifers).
  • You want more flowers or bigger fruit: the booster matching that stage.
  • You want convenience in pots without feeding every week: Organic Fertilizer Tablets.

Frequently asked questions

Do these sachets replace regular feeding?

No, they're a targeted boost for a specific moment (transplanting, deficiency, blooming). Maintenance feeding with a universal or specific fertilizer is still needed.

Can I combine several sachets at the same time?

Generally yes, as long as they address different needs (for example, a rooting agent after transplanting and later a bloom booster), but avoid duplicating two products for the same problem in the same application.

What's the difference between the greening agent and the conifer anti-yellowing treatment?

The universal greening agent corrects iron chlorosis in any plant; the conifer anti-yellowing treatment is specifically formulated with magnesium for pines and cypresses.
