The summary

  • Analysis: a liquid organic fertiliser with an NPK of 2-7-4, with amino acids, enzymes and trace elements.
  • Dose per watering: 1 to 4 ml per litre of water, increasing gradually.
  • When to use: from the appearance of the first flowers until harvest, in the same watering can as Bio-Grow, which continues during flowering.
  • Away from the pond: for pots and separate growing loops, never in the fish water.

Organic flowering fertiliser to feed tomatoes, peppers and strawberry plants right up to harvest

BioBizz Bio-Bloom is a liquid organic flowering fertiliser, NPK 2-7-4, for tomatoes, peppers, courgettes and strawberries. It is dosed at 1 to 4 ml per litre of watering, from the first flower to harvest, with Bio-Grow in the same watering can. In aquaponics, it only feeds pots or a growing loop separate from the pond.

When a tomato plant is covered in flowers, its needs change: it has finished most of its foliage and now devotes its reserves to forming fruit. It then needs less nitrogen and more phosphorus and potassium. Bio-Bloom, from the BioBizz range, is the liquid organic fertiliser designed for this phase, with an analysis of 2% nitrogen, 7% phosphorus and 4% potassium, written NPK 2-7-4.

🌸 What the formula contains

These three major nutrients are accompanied by amino acids, enzymes, trace elements and plant-derived hormones. Phosphorus is involved in the plant's energy transfer and supports flowering, while potassium regulates the movement of water and sugars towards the fruit, determining its size and flavour. Because the formula is organic, some of the nutrients are in a form that the micro-organisms in the grow medium must first mineralise, that is, convert into ions the roots can absorb. You therefore feed both the plant and the soil life around it.

Bio-Bloom complies with the European regulation on organic production, which means you can use it in a vegetable garden run organically. It is used in soil, compost and coco fibre, and its use is also intended for hydroponics and aeroponics. On coco fibre, a grow medium with no microbial life at the outset, it is advisable to adjust the pH of the solution and to combine it with an enzymatic activator such as Acti-Vera, which speeds up the release of organic elements to the roots.

Tomatoes and aubergines

From the first flowering truss to the last autumn harvests, with a dose that increases week by week.

Peppers and chillies

A long, staggered flowering period, to be supported without excess nitrogen, which would make the foliage leggy.

Strawberry plants

Successive fruits over several months, which draw a lot of potassium from the grow medium.

Courgettes and cucumbers

Fast, abundant production that needs regular feeding at every watering.

Top up the calcium when you water with rainwater

Bio-Bloom provides phosphorus and potassium, but not enough calcium to make up for water that has none. Rainwater or reverse-osmosis water contains almost none, and this shortage shows up on tomatoes as a black patch at the end of the fruit, blossom end rot. A calcium magnesium supplement added to the watering water before the fertiliser restores the balance. You keep the flexibility of soft water without exposing your first fruit to this defect.

Keep this fertiliser out of the fish water

Bio-Bloom is dosed for a grow medium or a nutrient solution, not for water that houses fish. Its organic matter breaks down in water, consuming dissolved oxygen and releasing ammonium, two effects that a pond tolerates poorly. Water your pots away from the pond, and never let drainage water reach the circuit.

Shake the bottle before each use, then add 1 to 4 ml per litre to your watering water. The recommended working dose is between 2 and 4 ml per litre: start with the low dose at the first flowers, then increase it as the fruits form. For a 10-litre watering can, that means 20 to 40 ml at full production. It is applied at every watering, in the same can as Bio-Grow, the growth fertiliser from the same range, which the programme also keeps going during flowering. In the last week before harvest, water with plain water only.

🐟 Bio-Bloom and aquaponics

In a classic aquaponic system, known as a coupled system, the same water circulates in a loop between the pond and the plants. The fish waste, converted by the bacteria in the filter, provides most of the nutrition, and everything you add for the plants also passes through the fish's gills. This is why Bio-Bloom is not used in this system: its organic load would add to that of the feed, whereas the biofilter is sized to handle only the fish waste. It still has a place with an aquaponics grower, provided it stays in the plants' water only.

The first solution is decoupled aquaponics. The fish water is sent to a separate growing loop that never returns to the pond, so the plants' solution can then be supplemented freely. Your tomatoes and peppers receive the nitrogen from the fish there, along with phosphorus and potassium from a flowering fertiliser. The second, simpler solution is to grow fruiting vegetables in pots beside the system, in potting compost or coconut fibre, and water them with water taken from the pond and topped up with Bio-Bloom.

In the coupled system itself, the deficiencies you will most often encounter involve potassium, calcium and iron, and they can be corrected with fish-safe products. Potassium and calcium are supplied as hydroxides when the pH drops, and iron in chelated form, at a rate of 2 mg per litre every three weeks. Potassium bicarbonate plays the same buffering role while also supplying potassium to fruiting plants. The article on deficiencies in aquaponics helps you identify the missing element from the leaves.

🧴 Sizes and storage

The 250 ml bottle is enough for a season on a few plants grown in pots, since it makes up about 80 litres of solution at 3 ml per litre. The 1-litre size covers a balcony of fruiting vegetables or a small vegetable garden, and the 5 and 10-litre containers suit a greenhouse or a large garden watered every week. Close the cap tightly after use, keep the bottle out of the reach of children and protected from frost, and always shake it before measuring, because a natural sediment forms at the bottom of a liquid organic fertiliser. Prepare the solution on the day of watering rather than storing it.
