Frequently Asked Questions

Vermi Trade has researched extensively and consulted with experts in the field of to provide this information to help you use your Vermi Worx® and other Vermi Trade products more effectively.

Can you save me money?

Yes! When compared to other organic recycling methods now in use or under consideration by a number of municipalities in South Africa, Vermi Trade offers waste producers significant savings. The capital investment involved in the Vermi Trade Vermicast system is 50% less than most organic waste recycling systems currently deployed, or under consideration by urban and agricultural waste producers.

Can you save me time?

Timing is everything! From start to finish – in less than four weeks – the Vermi Trade system produces a much more environmentally-stable, high-value product. Lower production throughput times, combined with lower initial capital investment requirements and the product revenue from castings make this your superior waste recycling option.

Do you deliver?

We deliver anywhere in Gauteng. Deliveries outside of Gauteng are at an additional cost.

Can I order in bulk?

Yes, we tailor solutions to our individual clients’ needs, including the sale and delivery of products in bulk.

Who can use Vermi Trade products?

We cater to EVERYONE’S soil and plant needs. Whether you are a large-scale farmer or garden enthusiast, Vermi Trade is for you. Worm casting applications can be used in organic farming, vineyards, golf courses, green roofs, green houses, urban gardens, organic turf care and soil replacement, and land reclamation.

What organic wastes can VERMI TRADE help me recycle?

We offer vermicasting technologies for accelerating the recycling of waste streams such as inedible plant biomass and human wastes, and returning this organic matter back to the agricultural food chain.

Do the Vermicastings smell?

Unlike other manures, the castings have a pleasant earthy aroma that won’t upset you or your neighbours. Any bad odour is a sign that fermentation has not reached its final goal and that the bacterial processes are still going on.

What do the castings do?

Castings increase soil health by providing a natural source of organic matter with high nutrient and moisture holding capacity. The addition of active, slow release microbial life to the soil supports the natural development of tender plant roots with valuable nutrients and trace minerals. Naturally produced organic matter improves soil texture, water retention and drought resistance. Castings also contain no toxins and so don’t contaminate ground water.

Why should I use Vermicastings instead of other soil products?

Worm castings contain a diverse microbial population. These microorganisms enhance soil fertility by turning complex substances into plant-available nutrients. Bacteria in the worms’ digestive systems synthesise a whole series of biologically active substances, including plant growth regulators. Castings contain up to five times the plant available nutrients found in average potting soil. And, unlike other potting soil mediums, nutrients in castings are water

My worms are trying to escape, what I am doing wrong?

Worms are very specific about what conditions they live in and if they don’t like them, they will try to leave – en masse. If this is happening, you must go back and check on what may be forcing them to want to leave. These include what you are feeding them, if the bedding material too moist, the pH level of the bedding material, etc. These problems can usually be fixed quickly and easily, and without losing too many worms.

I have ants in my worm bin. How can I get rid of them?

Having ants moving into your worm bin usually means that your bedding material is not moist enough. To fix this problem, gently turn the bedding material with a garden fork and water the bedding material remembering not to over water. Also, if possible, rest the legs of your worm bin in a container of water to discourage the ants from returning. Alternatively, you can make trenches on the upper crest of the tanks and keep them filled with water.

Little flies have invaded my worm bin. How can I get rid of them?

These little fruit flies are usually there because of any fruit and vegetable waste put into the bin. To get rid of them or at least control them, bury the waste into the bedding material a little, and cover with moist newspaper or jute bag. You may also sprinkle soil on the waste, or just leave it covered with a mesh.

My Vermi Worx® has become smelly and the worms haven’t eaten all the food. What have I done wrong and how can I fix it?

This is a sign that you have overfed your worms and they cannot keep up with the amount of food that is being added into the worm bin. To fix this problem, stop feeding them and remove any of the uneaten food, and then gently turn over the bedding material with a garden fork so as to aerate the bedding material. If acidic, add a handful of lime to correct the pH levels and then start feeding the worms again, only little amounts at first, so you can get an idea of how much they can consume so as not to over feed them again.

Whilst I am away on holidays will my worms starve to death?

No, they should be okay, but avoid adding any fresh food material and cover the bedding surface with moist newspaper or Hessian (gunny bags) to keep the bedding material from drying out. You may also leave mud pots containing water covered with lids, half buried into the pits/tanks. Even if the surrounding material dries up, the earthworms may move and stay beneath these moist pots. If you are planning to go away for an extended time (month or more) you may want to get a friend or neighbour to take over looking after your worms for the time you are away.

If I cut a worm in half, will I have two worms?

The answer is NO, so be careful when turning your bedding over so as not to cut any worms in half.

When is the compost ready?

The compost is ready when the material is moderately loose and crumbly, and the colour of the compost is dark brown. It will be black, granular, lightweight and humus-rich. To facilitate separating the worms from the compost, stop watering two to three days before emptying the beds. This will force about 80 percent of the worms to the bottom of the bed, and they will naturally move to the top tray where the food is. The rest of the worms can be removed by hand, and are ready to be transferred into the next round of compost making. The vermicompost is then ready for application.
