Scatter 50–75g\/m² and water in well. The fine granules settle between the grass blades and break down at the soil surface, improving root depth, drought tolerance, and soil biology. Apply 2–3 times per season. For a complete organic lawn feed, combine with Nitrogen Meal — the nitrogen drives the green-up and the seaweed provides trace minerals, stress tolerance, and soil conditioning that nitrogen alone cannot.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-sm-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-sm-faq5\"\u003eIs it safe for all plants?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eYes. Seaweed is universally beneficial and safe for all plants: vegetables, fruit, herbs, flowers, roses, trees, shrubs, lawns, houseplants, succulents, and hydroponic crops. The bioactive compounds in seaweed operate through fundamental plant processes that are common to all species. There is no known plant that is harmed by seaweed meal at recommended application rates.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-sm-faq6\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-sm-faq6\"\u003eDoes it smell?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eIt has a mild, slightly salty marine smell — similar to being near the coast. It is not strong or unpleasant, and it dissipates quickly once the meal is watered into the soil. It does not attract flies, pests, or animals. For indoor use in houseplant pots, the smell is detectable briefly after application but fades within a day or two as the granules absorb moisture and begin breaking down.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-sm-faq7\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-sm-faq7\"\u003eCan I make a liquid feed from the meal?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eYou can steep seaweed meal in water for 24–48 hours to make a cold-infusion tea — the dissolved minerals and organic compounds produce a useful liquid drench. However, seaweed meal does not dissolve fully — it is a granular, not a soluble product. For a true liquid seaweed feed that dissolves completely with no residue, use Dr Forest Seaweed Powder instead. The powder is specifically processed for liquid application and delivers a more concentrated, immediately available biostimulant effect.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-sm-faq8\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-sm-faq8\"\u003eHow should I store it?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eStore in a sealed bag or container in a cool, dry place out of direct sunlight.

It is measured with a refractometer — a simple handheld instrument that reads the refractive index of a drop of sap and expresses it as degrees Brix (°Bx). A tomato at 4°Bx is watery and bland. A tomato at 8°Bx is sweet, complex, and flavourful. A tomato at 12°Bx is exceptional.\u003c\/p\u003e\n    \u003cp\u003eBrix is not just a flavour indicator. It is a \u003cstrong\u003ecomprehensive proxy for plant health\u003c\/strong\u003e. High-Brix plants photosynthesise more efficiently, produce more secondary metabolites, have stronger cell walls, accumulate more vitamins and minerals, and — critically — are naturally more resistant to insect pests and fungal diseases. This is not coincidental. Insects are attracted to plants with low sugar density and high free amino acid content — the biochemical signature of a poorly photosynthesising, nutritionally incomplete plant. Raising Brix moves the plant out of this vulnerability zone.\u003c\/p\u003e\n    \u003chr class=\"drf-sep\"\u003e\n    \u003ch3\u003eSeven growth promoters — how each one drives Brix upward\u003c\/h3\u003e\n    \u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e01\u003c\/span\u003e\u003ch4\u003eTriacontanol — the Photosynthesis Accelerator\u003c\/h4\u003e\n\u003cp\u003eTriacontanol is a C30 primary fatty alcohol found naturally in plant leaf waxes and beeswax. When applied exogenously (as a foliar spray), it directly increases the rate of photosynthesis by improving the efficiency of Rubisco — the enzyme that fixes CO₂ into sugar during the Calvin cycle. Research shows that triacontanol-treated plants fix more carbon per unit of light, producing more sugar per hour of sunshine. More sugar production means higher Brix, more growth, and greater dry matter accumulation. Triacontanol also stimulates the production of growth hormones by the plant itself, amplifying the effect of the other six promoters in the formulation.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e02\u003c\/span\u003e\u003ch4\u003eCytokinins — Cell Division \u0026amp; Anti-Senescence\u003c\/h4\u003e\n\u003cp\u003eCytokinins drive cell division in meristematic tissue — the growing tips of shoots and roots.

It is measured with a refractometer: squeeze a drop of sap onto the lens, close the cover, and read the scale through the eyepiece. A basic optical refractometer costs £15–£25 and requires no batteries or calibration beyond an occasional zero check with distilled water. Higher Brix = sweeter, more flavourful, more nutritious, and more pest-resistant crops.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-bx-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-bx-faq2\"\u003eWhat is triacontanol?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eTriacontanol is a C30 primary fatty alcohol found naturally in plant leaf waxes, beeswax, and some plant oils. When applied exogenously as a foliar spray, it directly increases the rate of photosynthesis by improving Rubisco efficiency — the enzyme responsible for fixing CO₂ into sugar. Research consistently shows that triacontanol-treated plants produce more dry matter, accumulate more sugar, and show higher growth rates than untreated controls. It is one of the most potent natural plant growth regulators known, and it is the signature compound in Brix+.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-bx-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-bx-faq3\"\u003eIs Brix+ a fertiliser?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eIt is a biostimulant, not a primary fertiliser. It contains modest nitrogen (0.26%), potassium (1.65%), sulphur (0.37%), and magnesium (0.15%), plus 74 trace minerals — but its primary value is the seven growth promoters that drive photosynthesis, cell division, stress tolerance, and sugar accumulation.

High-Brix plants have lower free amino acid levels (they are being incorporated into proteins efficiently), higher sugar concentrations (which insects struggle to digest), and greater concentrations of phenolic and terpene defence compounds. The net effect is that high-Brix plants are less attractive, less digestible, and more chemically defended than low-Brix plants.
