Description
Bio Bloom is a vegetable-based, all-organic complete fertiliser designed for use during the productive flowering and fruiting stage of plant development. Biobizz Bio Bloom has an NPK ratio of 2-7-4 to ensure theres a small amount of nitrogen and plenty of phosphorus and potassium to stimulate abundant floral and fruit growth.
During the flower and fruiting stage of development, plants need high levels of the key elements potassium and phosphorous. Both these elements play a vital role in helping plants form flowers and fruits. Usually, a shift to the flowering light cycle and a switch to a bloom nutrient with a high concentration of potassium will be enough to trigger the productive stage of the growth cycle.
As well as the key elements nitrogen, phosphorus, and potassium, Bio Bloom incorporates a range of trace elements and hormones as well as containing a carefully selected mix of enzymes and amino acids. This tailored formulation works to strengthen your plants, enrich the soil, and work with beneficial micro-organisms to promote healthy and vigorous production of flowers and fruits in a completely natural way. No chemical additives are necessary.
Key features of Bio Bloom include:
- High levels of potassium and phosphorous to boost flowering
- Enriched with amino acids, hormones, and 70 trace elements
- Ideal for organic gardeners growing in soil
- Increases and enhances the flavour of yields
- Made entirely from vegetable extracts
Our Opinion:
Bio Bloom is one of the original and best organic fertilisers for the flowering and fruiting stage. Weve had great feedback from our organic customers and it seems the mix of macronutrients, micronutrients, enzymes and amino acids is spot on for encouraging and stimulating flowering and fruit production. Overall, a great complete fertiliser from respected Dutch brand Biobizz.

Questions
When do I start using Bio Bloom?
From the first week of flowering. Biobizz's schedule leaves it out during propagation and vegetative growth.
Do I stop Bio Grow when I start Bio Bloom?
No. Biobizz's schedule runs the two together through flowering: Bio Grow at a lower dose, Bio Bloom rising as flowering goes on.
