Organic inputs in small quantities can be expensive or hard to purchase. BOGI buys commercial quantities of key inputs and distributes that in our 'shop' but strictly for members only.
They can be bought at the monthly meetings or by contacting the BOGI shop coordinators on
So here are our products, what they do, how much to apply and how to apply them.
This organic form of boron is safe to plants unlike other forms. One application will supply boron to the plants for two years. This is particularly important in sandy soils and in crops such as paw paws, avocado, and zucchini. Use at 100 g per 10 metres square.
For fruit trees: each fully grown fruit tree generally has a root area over about 4 to 8 square metres so apply 40 to 80 g spread over this area.
And yes, measure the quantity on your kitchen scales and get the rate right.
Supplies calcium to the soil in a form that allows the soil bacteria to rapidly make the calcium available to the plant. Apply as regular soil drenches using 4 ml liquid lime mixed in water to each square metre. Initially use every 2 months. After 6 months use every 6 months. Shake well before use.
This seaweed product is a booster for the plant and soil microbial life. It supplies minor trace elements and plant growth agents. Apply prior to planting as a soil drench and then monthly as a foliar spray or in a watering can. For quantities and how to apply, see below.
This fish product supplies nutrients to the plants and soil microbes. Apply the same as Liquid kelp.
This microbial product contains microbes to assist soil and plant functions. Apply the same as Liquid kelp.
How much and how to apply kelp, fish and microlife?
Foliar sprays: 10 ml per litre - mix in a spray can and spray the leaves on both sides till
they are moist. Do this monthly for best results.
These rates may appear low. However, repeated monthly in addition to the base fertiliser before planting, they give best results.
Soil drenches: 2 ml per meter square. These are best done before planting as part of base fertilising.
Calculate the area to be treated in square metres: e.g. a three meter long and one meter wide bed is 3 meters square,
Multiply that by 2 to find the millilitres needed, in this case 3x2ml= 6ml.
Mix 6 ml of the product in a watering can and water evenly over the bed.
Molasses not in stock
Molasses boosts general microbial life. It is available in small quantities at many shops.
Measure the area to be treated in square meters, multiply this by 8 to find the millimetres needed, mix this in a watering can and water evenly over the bed.
