A liquid organic fertiliser formulated for the intense nutritional demands of balcony and container plants — combining hydrolysed proteins, an organic boron complex, a full spectrum of organically chelated trace elements (Fe, Cu, Zn, Mn, B, Mo), and potassium salts to deliver complete macro and micronutrient support to plants growing in the most demanding container conditions. pH 5.5–8.5. Supplied in a bottle made from ISCC PLUS certified plastic — free from fossil petroleum content.
Dr.Soil Organic Fertiliser for Balcony Plants is the most nutritionally complete formulation in the Dr.Soil fertiliser range — specifically designed for the reality of balcony and container growing, where plants in restricted volumes of substrate are subjected to higher light intensity, faster drying, more frequent watering (and therefore more frequent nutrient leaching), and greater temperature fluctuation than garden-grown plants ever experience.
The formulation combines hydrolysed proteins (free amino acids as immediately absorbable nitrogen and protein synthesis precursors), an organic boron complex compounded with aminoethanol (for flowering, fruiting, and sugar transport to reproductive tissues), and a full spectrum of organically chelated trace elements: iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), boron (B), and molybdenum (Mo). These six micronutrients are chelated — bound to organic molecules that protect them from precipitation, soil lockup, and oxidation during delivery — ensuring that each element reaches the root cell in bioavailable form rather than becoming chemically unavailable in the substrate as inorganic salts frequently do. Potassium salts complete the formulation, supporting water use efficiency, stomatal function, and the movement of photosynthates to growing points and flowers.
The very wide pH tolerance (5.5–8.5) means this fertiliser remains effective across the full range of balcony plant species and substrate types without adjustment.
The bottle is produced from plastic certified to the ISCC PLUS standard (International Sustainability and Carbon Certification) — an independently audited European certification that guarantees the plastic is derived from renewable or recycled feedstocks rather than fossil petroleum. It contains no virgin fossil-derived plastic content. Chain-of-custody traceability is verified at every stage of production.
Balcony containers are nutritionally depleted environments by nature: the restricted substrate volume, frequent watering, and high plant density mean that nutrients are consumed and leached far faster than in garden soil. Conventional fertilisers replace macronutrients but neglect the micronutrients that become limiting precisely when macronutrient supply is adequate and plant growth is active. Dr.Soil Organic Fertiliser for Balcony Plants addresses the complete nutritional picture:
This formulation is designed for all plants grown in balcony boxes, window boxes, patio containers, and hanging baskets: petunias, geraniums (pelargoniums), lobelia, calibrachoa, bacopa, verbena, impatiens, fuchsias, begonias, bidens, diascia, osteospermum, surfinias, and all other balcony and patio annuals and tender perennials.
Balcony plants are selected and bred for continuous, prolific flowering in exposed, restricted conditions. This combination of high ornamental performance and challenging growing environment creates specific nutritional demands that a standard garden fertiliser cannot adequately meet:
Dilute 40 ml of concentrate per 1 litre of water. Mix thoroughly. Apply to moist substrate — never to dry roots. Apply as a soil drench directly to the container, or as a dilute foliar spray for faster micronutrient delivery during periods of high demand.
| Application | Dilution | Frequency |
|---|---|---|
| Soil drench (main method) | 40 ml per 1 L water | Every 1–2 weeks throughout the growing season, from planting until autumn |
| Foliar spray | 40 ml per 1 L water | Every 2 weeks; apply in morning or evening; particularly effective for rapid correction of visible micronutrient deficiency symptoms |
In hot, dry periods when watering frequency increases, apply at every second or third watering to compensate for the accelerated leaching of nutrients from containers.
Classified as non-hazardous under EU Regulation (EC) No. 1272/2008 (CLP). Non-flammable and non-explosive. Store in the original sealed bottle between 5°C and 30°C, away from children. Avoid prolonged skin contact; wash hands after use. If contact with eyes occurs, rinse thoroughly with clean water. Do not ingest. Do not allow to enter drains or surface watercourses.
