Ecothrive Charge 3.5kg is a premium organic soil amendment made from naturally produced mealworm frass. With a balanced NPK of 3.5-2.5-2, beneficial microorganisms and naturally occurring chitin, Charge improves soil fertility, supports nutrient cycling and helps create a biologically active root environment for strong, resilient plant growth.
Charge is one of Ecothrive's flagship soil amendments and can be used across potting soil, living soil and coco coir. It can be mixed through growing media before planting or applied later as a top-dress, making it an extremely versatile organic input for propagation, vegetative growth and productive crops.
The current Charge formulation is supplied as small compressed frass chunks rather than the older loose powder. Ecothrive introduced this format to reduce dust, simplify application and increase concentration. The compressed product is approximately 50% more concentrated than the previous mealworm frass powder by volume.
This is why the current 3.5kg pack replaces the old 10L Charge format. Application rates should therefore be measured by weight using Ecothrive's current gram-based guidance rather than by comparing the volume of the new product with the old loose frass.
Charge is also Soil Association approved for organic cultivation, making it suitable for growers looking to build fertility and biological activity using naturally derived inputs.
Insect frass is the material produced during insect rearing and includes insect waste together with residual feed material and fragments of shed exoskeleton.
Ecothrive Charge is produced from organically fed mealworms. The resulting material provides organic plant nutrition while also supplying carbon and other compounds that support biological activity within the growing medium.
Unlike a conventional soluble mineral fertiliser, Charge works closely with the biology of the root zone. Microorganisms break down its organic components and cycle nutrients into forms that can be used by plants.
This makes Charge particularly relevant to living soil, organic growing and other systems where growers want to maintain an active soil food web rather than relying exclusively on soluble mineral nutrition.
One of the distinctive characteristics of Ecothrive Charge is its naturally occurring chitin.
Chitin is a structural material found in insect exoskeletons. Mealworm skins and other insect fragments within Charge provide a natural source that can be utilised by microorganisms in the growing medium.
Chitin acts as a food source for particular beneficial microorganisms, including fungi. As these organisms proliferate and break the material down, biological activity within the root zone increases.
Ecothrive also highlights chitin's role in stimulating natural plant defence responses. Plants recognise compounds associated with chitin and can respond by activating their own defence mechanisms.
Charge should therefore be viewed as more than an NPK fertiliser. Its combination of organic nutrition, microbial activity and chitin is central to how the product is intended to work.
Ecothrive changed Charge from its traditional loose mealworm frass powder into a compressed crumb format in 2024.
The small compressed pieces significantly reduce dust and make measuring, mixing and top-dressing cleaner and easier.
More importantly, Ecothrive states that the new compressed Charge is approximately 50% more concentrated than the previous powder form by volume.
As a result, the current 3.5kg bag is the replacement for the previous 10L format. Growers familiar with the old product should follow the current weight-based application rates rather than attempting to use the new material at the same volume as the old loose frass.
Charge can be thoroughly mixed into potting soil before planting. Ecothrive recommends adjusting the rate according to plant age and required fertility:
Mix Charge evenly through the growing medium before planting so the amendment is distributed throughout the root zone.
Follow-up top-dress applications can be made approximately every 2-4 weeks during active growth where required. Ecothrive recommends making the final Charge application approximately five weeks before harvest.
Charge can also be mixed through coco coir to introduce organic nutrition and biological activity into the root zone.
Thoroughly distribute Charge through the coco before planting. Follow-up top-dress applications can be made every 2-4 weeks where required.
Charge complements a coco feeding programme rather than automatically replacing the crop's complete nutritional requirements. Irrigation, EC, pH and base nutrition should still be managed appropriately for the crop and growing system.
Charge can be applied directly to the surface of established pots and living soil beds, allowing additional organic nutrition and biological inputs to be added without remixing the growing medium.
Spread the measured amount evenly, lightly scratch it into the upper 2-4cm of growing medium and water after application.
Top-dressing can be repeated approximately every 2-4 weeks during active growth according to plant demand and the wider nutrition programme.
Charge is equally suitable for outdoor beds, borders, vegetable gardens, fruit crops and ornamental planting.
Apply approximately 250-500g per m². Prepare the planting area and lightly fork Charge into approximately the top 10cm of soil before planting or sowing. A follow-up top-dress can be made four to six weeks later.
Apply approximately 80-160g per m² around established plants and water thoroughly. Applications can be repeated approximately every four to six weeks during active growth where required.
The total coverage depends heavily on the growing medium and fertility level required.
At 1-4g/L, a 3.5kg bag can amend approximately 875-3,500 litres of potting soil.
At 2-6g/L, a 3.5kg bag can amend approximately 583-1,750 litres of coco.
At 50-100g/m², a 3.5kg bag provides approximately 35-70m² of top-dress coverage.
These figures demonstrate why the compressed 3.5kg format provides substantial coverage despite appearing physically smaller than the old 10L bag.

Yes. Charge can be used at reduced rates for seedlings, cuttings and lower-fertility mixes, allowing young plants to benefit from organic nutrition and biological activity without using the higher rates intended for established plants.
Yes. Charge can be spread over the surface of pots or beds, lightly scratched into the upper 2-4cm of soil and watered in. This makes it easy to supplement established plants without disturbing the root zone.
For container-grown plants, Ecothrive recommends follow-up top-dress applications approximately every 2-4 weeks where required. Outdoor established crops can generally be top-dressed every 4-6 weeks during active growth.
Yes. Charge can be incorporated into outdoor soil before planting or applied around established vegetables, fruit, flowers and ornamental plants as a top-dress.
Charge supplies valuable organic nutrition and biological inputs, but whether it provides all required fertility depends on the crop, growing medium, container size and cultivation method. It can be used alongside other compatible Ecothrive amendments where additional or stage-specific nutrition is required.
Charge is a single premium mealworm frass amendment focused on organic nutrition, beneficial biology and chitin. Life-Cycle is a broader multi-ingredient amendment containing Charge alongside insect meal, neem, rock phosphate, seaweed, minerals and other ingredients for building and rejuvenating complete living soil mixes.
The 3.5kg format is ideal for growers using substantial volumes of soil or coco, larger living soil beds, commercial horticulture and anyone regularly using Charge as part of an ongoing organic growing programme.
