During the vegetative phase, nitrogen drives leaf and stem growth. But once the first flowers open, \u003cstrong\u003ephosphorus and potassium\u003c\/strong\u003e become the dominant requirements — phosphorus to fuel the energy-intensive processes of flower formation, pollination, and fruit set, and potassium to control water balance, sugar transport, and the flavour compounds that determine eating quality. Continuing to feed a high-nitrogen fertiliser during flowering produces more leaves at the expense of flowers and fruit. The correct move is to switch to a high-P, high-K feed — and this is that feed.\u003c\/p\u003e\n    \u003cp\u003eBloom Booster is a \u003cstrong\u003esolution grade\u003c\/strong\u003e organic fertiliser — a concentrated powder that you add to water to create a fast-acting nutrient drench. The 2-10-5 ratio is deliberately weighted toward phosphorus, with moderate potassium and low nitrogen to support the reproductive phase without promoting excess vegetative growth. The nitrogen and just under half the potassium are \u003cstrong\u003efully water-soluble\u003c\/strong\u003e, delivering nutrients into the root zone within hours. The phosphorus and remaining potassium are \u003cstrong\u003emicronised to ultra-fine particle size\u003c\/strong\u003e for rapid breakdown even though they are not technically soluble.\u003c\/p\u003e\n    \u003cp\u003eThe formulation includes \u003cstrong\u003eamino acids\u003c\/strong\u003e enriched with humic and fulvic acid for enhanced nutrient uptake, \u003cstrong\u003esoluble seaweed extract\u003c\/strong\u003e providing growth hormones and trace minerals, and \u003cstrong\u003emicronised gypsum and magnesium mineral\u003c\/strong\u003e to keep calcium and magnesium balanced during the demanding flowering and fruiting phase. This is not a bottled liquid — you are not paying to ship water across the country.

Each flower bud that differentiates from a vegetative growing point requires an enormous surge of ATP — the phosphorus-dependent energy molecule — to power the rapid cell division and specialisation involved. Adequate phosphorus supply at bud initiation results in more flower buds, larger individual flowers, and a longer flowering period.

When potassium is adequate, sugar transport is efficient and fruit develops full sweetness, complex flavour, and dense texture. When potassium is deficient, fruit is watery, bland, and prone to splitting.

Bloom Booster is a fast-acting solution grade powder that delivers nutrients within hours — the on-demand boost when plants are in peak flower or fruit production. Use Bloom 2-8-4 as your regular granular top-dressing and Bloom Booster as a liquid supplement between applications, during heavy fruiting, or for plants in containers that need rapid replenishment.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-bb-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-bb-faq5\"\u003eCan I use Bloom Booster on orchids and flowering houseplants?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes — the clean solution format is ideal for indoor use. Use at the lower rate (¼ teaspoon per litre) every 2–4 weeks when orchids, African violets, peace lilies, and Christmas cacti are in bud or flower. The phosphorus encourages re-blooming in orchids that have finished their current flower spike. Reduce to monthly during vegetative growth phases and stop feeding during any dormancy period.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-bb-faq6\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-bb-faq6\"\u003eIs it just tomato feed by another name?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNo — although the high-P, high-K profile is similar to many tomato feeds, Bloom Booster is formulated more broadly. It includes amino acids, humic and fulvic acid, seaweed extract, calcium, and magnesium — components that most tomato feeds lack. It is designed for all flowering and fruiting plants, not just tomatoes: roses, soft fruit, annuals, orchids, fruit trees, peppers, courgettes, beans, and any plant that is in its reproductive phase. That said, it is an excellent tomato feed.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-bb-faq7\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-bb-faq7\"\u003eWill it burn my plants?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eAt the recommended rates, no. The amino acid nitrogen source is gentler than synthetic soluble feeds, and the balanced mineral profile (calcium, magnesium alongside PK) reduces the osmotic stress risk that causes burn. Do not significantly exceed the recommended rates. If in doubt, start at the lower rate (¼ teaspoon per litre) and increase if the plant responds well.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-bb-faq8\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-bb-faq8\"\u003eHow should I store Bloom Booster?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eStore the dry powder in a sealed container in a cool, dry place away from direct sunlight and moisture.
