How to apply our fertiliser?

Learn how to apply Dusty Clay’s geographically-blended Smart Release fertiliser to produce the best results for your grass, crops and garden. Our Smart Release fertiliser, although uniquely developed for your soil, works like most other Smart Release fertilisers on the market. An inexpensive hand-held or wheeled fertiliser spreader is all you need. You could always simply toss around a small amount of fertiliser using a bucket or measuring cup, going around your garden in a uniform fashion.

Why should I use Smart Release fertilisers?

Smart Release fertilisers work by decomposing. Unlike other fertilisers, they can’t be overly concentrated to burn crops, and likewise, they can’t be diluted to the point of ineffectiveness. Smart Release fertilisers require less re-application frequency compared to others, making them great for covering a broad area.

Is your fertiliser pet safe?

Our fertilisers are composed of natural rock minerals and plant matter and are completely safe for pets. Due to the nature of Smart Release fertilisers, you should avoid spreading it in large clumps that would encourage a pet to eat the Smart-Release pellets.

Is it possible to overdose my grass or plants?

With any fertiliser, there will come a point where too much fertiliser becomes harmful. We tend to recommend 250-400 kilograms of our fertiliser per hectare for the most effective results, but we’ve found soil to remain safe up to five times that dosage.

Can Dusty Clay fertiliser be used on food crops?

Dusty Clay fertiliser is made from as many natural sources as possible and the health of edible vegetation will be preserved when using Dusty Clay. The developers of Dusty Clay are former grain and pasture farmers and found their formula to be a healthy, effective growth solution for edible crops.

How should I store Dusty Clay fertiliser?

Keep any fertiliser out of direct sunlight in a cool, dry place, with temperatures ideally below the low 30’s. If you’re storing fertiliser in a separate container, please make sure it’s air-tight.

Is your fertiliser safe for delicate plants?

Yes. Our fertiliser is safe for use on all plants, and we can create tailored blends for you if you’re particularly concerned about any delicate plants you have. When planting delicate plants or fertilising unhealthy plants, it’s always best to be delicate. Scale back the volume of fertiliser and increase the frequency of fertilising to keep a better eye on the state of your plants.

How often should I apply Dusty Clay fertiliser?

The benefit of Smart Release fertilisers is they’re low maintenance. For existing healthy plants and grass, we recommend applying Smart Release fertiliser twice in Summer, and once right before the start of Winter to keep them flourishing.

How much should I apply?

The amount you need to apply depends on several factors that vary from backyard to backyard. For most of our fertilisers, we recommend applying anywhere from 15-40 grams per square meter,  depending on your environment. See the inside label on your bag, you will find full instructions for your specific blend.

Is your product Organic?

While we use many organic ingredients, we have not registered as such. We are passionate about ecology and wouldn’t use anything harmful to your soil.

Why is your fertiliser so special?

The reason why we’ve developed fertiliser blends specific for each region is because different soil types require different nutrients. The problem with most off-the-shelf products is that they’re often developed in labs or in completely different environments. It’s like giving your garden a Red Bull, your garden will go hard for a while and then crash. You need to BALANCE the minerals for longevity.

Why fertilise my grass?

Fertilising your grass results in less water usage and better-looking grass. If you’ve got a species of grass that doesn’t seem to grow well in Winter, using a Smart-Release fertiliser tailored to your soil not only improves turf quality, root growth and colour but it also builds cold resistance into your grass. They’re also great for some TLC after harsh conditions – adding a quick top coat of fertiliser after a party on your lawn ensures it stays in great shape after being trodden on all night.

My grass looks dead, what should I do?

When you’ve got grass that’s dying, it’s important to address it fast; grass can usually be recovered and made to look a million bucks again quite easily. Re-applying seeds in loosened soil becomes necessary when you’ve actually got dead patches. If you’ve just re-applied some seeds or are trying to revive your dying grass, we recommend the following steps:

  1. Spray the grass or seed with water and expose it to sunlight. Make sure not to drown it – but give it a good soaking and then regular watering.
  2. As soon as you’ve noticed growth, apply fertiliser. Visible growth means the water has reached the root structure. Make sure the soil is still damp before applying fertiliser for maximum effectiveness.
  3. Keep watering it gradually. After a week since the initial fertilising, inspect your soil to see if it’s staying moist. We recommend using a tool, like a screwdriver, to see if the soil is still hard (which means it’s dry) down to 10cm below before continuing to the next step. In between watering’s it should be moderately damp between 5-10cm below, but not sloppy on the surface.
  4. In a few weeks apply a coat of foliar fertiliser once the grass has gotten to a healthy state, with soft soil about 5-10cm down. This will keep your grass in great condition.

We recommend using a Smart-Release fertiliser, such as our fertiliser products, which is tailored to your geographical area. This is especially important when reviving dead grass, because off-the-shelf fertiliser products use up to 30% urea, which can burn fragile plant matter rather than revive it. Likewise, Cheap Potassium fertiliser used in most commercial mixes not only destroys the exchange capacity of your soil, but the high Chlorine content kills off soil life.  We can’t stress enough, the importance of being gentle; grass can be revived easily, whilst lack of water is likely the first issue, drowning it in water to speed the process up only worsens the problem.
