Biocast applications:



Biocast is a must-have product for the home gardener wanting a lush, healthy garden. From lawns to hedges, pot plants, flower beds, veggies and ornamental trees; the living microbes and their byproducts found in Biocast will help you out. We have yet to meet a plant that doesn’t like it!

Suggested uses

Here are some ideas for how Biocast can be applied in your garden, based on what customers have already tried and given their positive feedback on. For information on how exactly to apply it see Application.

A vibrant garden – general health

To keep your garden looking its best, we recommend a monthly foliar application (on the leaves) of Biocast diluted 20:1 with water.

Establishing new gardens, landscaping

If you want your new garden to look like it’s been there for ages, use Biocast as a transplant drench when planting your new plants. New root growth will be stimulated, allowing the plant to get growing straight away. To help it along, use a foliar spray/ watering can once a fortnight in the early days then once a month.

Establishing new lawn

When your lawn is laid, water it in and then apply Biocast as a foliar (we suggest a watering can for most urban sized blocks, or backpack sprayer with coarse droplets). Add Part A and Part B to your watering can as per the mixing instructions then dilute 1:20 with water. Water at a reasonable walking pace to wet the grass – no need to soak. We recommend an application on the first day then once a week for the first month. Apply monthly to keep your lawn looking great!

Fruit trees that aren’t fruiting well

The ability to bare copious, full and flavoursome fruit is a sign of a plant’s health. Biocast works to increase that health naturally through the action of microbes and their by-products. We recommend foliar (leaf surface) application of Biocast diluted with water 20:1 up to once a fortnight between the first sign of buds and the end of fruiting for plants that look tired, and once a month for maintenance.  Also check that your trees are well watered and have enough mulch. If they still have deformed or discoloured leaves and fruit after a couple of months of Biocast it is likely that you will need to address a soil nutrient deficiency.

Flowering shrubs (including roses) that aren’t flowering well

We have had wonderful stories such as the rose bush that flowered and had a flush of new growth with Biocast after five years of nothing. We recommend a monthly foliar application of Biocast diluted 20:1 with water using a watering can or backpack sprayer with coarse droplets and seeing what happens!

Vegetable gardens

Biocast is excellent for growing your own nutrient-dense, flavoursome food! Use a watering can to apply Biocast diluted with water 20:1 to the leaves of all your veggies weekly for fast growing plants such as leafy greens, and fortnightly for other plants. As with fruit trees, give your plants the best chance by also providing adequate water and mulch, and addressing any mineral deficiencies.

Pot plants

Separated from healthy, living soil, pot plants need all the help they can get! To keep your pot plants looking good we recommend a fortnightly foliar application by diluting Biocast with water 20:1 in a watering can, up to once a week for plants which are struggling.

Pests and diseases

Biocast works to bolster the plant’s health and immune system so that it can have a better chance of overcoming pests and diseases itself. Being packed full of a diverse array of microbes it also provides competition on the plant surface for  bacterial and fungal diseases. This means that Biocast is not killing the disease, rather it is helping to keep it in check. Some of the things Biocast can assist with include mildews, black spot, even caterpillars and stink bugs. Please note that for sooty mould and scale, ants must be controlled. We recommend weekly foliar applications (on the leaves) until the plant looks recovered, then a monthly maintenance application. Biocast is not effective against birds and mammals which want to eat your plants!
