Now you can choose a Top Soil or Garden Soil from our UltraGROW Range that is just right for your garden.

Composting Wind RowsHere at Centenary Landscaping Supplies we really care about our soil and have worked hard to ensure our range is one of a kind. Right from the very beginning some 28 years ago, our focus and specialty was soil and specifically the development of a humble little soil known as Special Blend. At the time, Special Blend was so different to anything else available on the market and really became the basis on which all other soils in South East Queensland were modeled from. Since then we have worked very hard with top soil manufacturers, soil scientists and industry professionals to develop our fantastic UltraGROW range.

The bottom line is, we care about soil, and that is a rare thing these days.

Understanding Your Garden Soil, Top Soil and Plants:

What Do Plants Want?

There is probably a whole library full of books that tell us how to have a successful garden and how to make plants thrive but here we have tried to get to the basics of what you need to do to have a beautiful garden. What do plants need to thrive?

  • Sunlight
  • Water
  • Nutrients
  • Well Drained Soil

It needs to be remembered that there is a huge range of plants available at nurseries and that they may well require the above in differing amounts …some plant species like shade, others prefer full sun; some may like drier conditions and some wet. So make sure when planning your garden that you discuss what your particular situation is with the Plant Nursery so they can advise the best types of plants for your specific situation. Once you have chosen the best plants for your design and location, it is time to turn your attention to the garden soil you choose from your premium topsoil supplier, Centenary Landscaping Supplies providing you a wide range of top soil prices and types from organic to natural topsoil in bulk soil loads to your site to a trailer load or a shovel full.

Natural Top Soil Compared with Manufactured Organic Soils…

When starting a new garden or laying a new lawn, you are often confronted with one of two situations.

First, you might find that there is plenty of top soil in the garden but it’s been compacted over the years and has been depleted of most of its “goodness”. In this scenario, the existing garden soil needs to be rejuvenated by digging in some enriched compost such as our “Earthgrow” Compost or Enviro Premium Compost or one of our animal based composts. If you spread a layer of about 100mm across the garden and then dig it into approx. the top 300mm of the existing garden soil, along with an organic fertilizer such as “Organic Extra”, the area will be revitalized, have improved drainage and increased nutrient levels and it will be ready to accept the new plants. Also consider saving on water by digging in Hydrocell.

Secondly, (and indeed in most cases), we find that the natural ground is as hard as concrete; very heavy clay or shale rock, which is too inhospitable to work with. Here, we need to import organic top soil and that leads us to call Centenary Landscaping Supplies and ask for some top soil that will meet your needs. What we have at Centenary Landscapes, is a range of organic soils that consist of a sandy loam top soil base mixed with various composted organics and fertilisers. This is screened through a 20mm mesh sieve to remove all the larger lumps making it easy to use and dig.

But why are organics used in these manufactured organic top soil mixes? Why don’t we just sell “straight” top soil? Well we do but for plants to thrive, the growing environment needs to provide: water, nutrients and air to the root system. In a natural top soil without organics, the particles are very close together, which makes it hard for water to drain through the soils, and hard for air to penetrate down to the roots of the plant. Opening up the top soil by blending through organic material, we are providing space for the air and water to move around and a much better physical environment for your plants to grow. Having the organics also provides a source of food and in dry periods the organics can act as small storage reservoirs to help the plant survive. So remember that the organics play a very important role in the success of the top soil blends we offer from all the major manufactures in SE Qld.

Making sure that the ingredients are fully composted is critical. This can take between six to eight weeks or more. Using non-composted material in top soil mixes can lead to what is called “Nitrogen Drawdown”… basically as the “fresh” organic material breaks down; it sucks some of the goodness from the garden soil, which can hinder plant growth. The time it takes to compost properly contributes to differing top soil prices and when very low prices are quoted by others there is a fair chance that shortcuts have been taken. We can do this too but we have chosen not to as it only leads to disappointment for each of us.

So once the plants have been chosen, give us a call and explain what you are trying to achieve. Our knowledgeable sales team will be able to advise you on which top soil blend will suit your project, both from the plants’ point of view…. and your wallet! If they are unsure, they will seek further expert advice for you.

The Three Golden Rules For Healthy Soil:

    1. ONLY USE FRESH NEW TOP SOIL – People often purchase and store their bulk soils for their gardens or lawns before they are ready to use it. This is the worst thing you can do as soil is a living and breathing organism. If you spread it in preparation for new turf but then do not lay that turf immediately, your soil will dry out and become hydrophobic (water repellent) and you may kill many of the microbial bacteria that are so important to your   soil. The same can happen if you stockpile it prior to placing into a garden bed. Garden soil needs to be alive with microbial bacteria.
    2. NEVER MECHANICALLY COMPACT – Top Soil is full of organic matter that breaks down over time and because of this, soils can be easily compacted, either by driving on it or driving over with compaction machinery. The soils structure needs to remain open so that air and water can freely pass through the top soil to the root zone. Along with nutrients, these are vital for good plant growth.
    3. REGULAR FEEDING – All our natural and organic top soils have a fixed amount of nutrients and trace elements necessary for good plant growth and plants will thrive initially. As plants use up these valuable nutrients, they will need to be replaced in the form of added fertilisers to maintain strong healthy plant growth. It is advisable to feed garden soil and lawns 3-4 times during the growing season, and at least once in winter when most plants are dormant, using either “Eco 88″ or “Organic Extra” fertiliser.

How Much Do I Need?

This is a very important question and one which doesn’t necessarily have a simple answer. The first thing to establish is just how bad your natural ground is, that is, can it be turned at all and how hard is it?

If we assume that it’s almost bare rock, then for general planting of smallish shrubs approx. 300mm depth of top soil is recommended for planting … this way, the new plants will have enough “good” top soil to establish themselves before they have to send roots into the really hard surrounding natural ground.

Now, every situation is different and the 300mm is just a general guide for most situations so when planning your project, give us a call at the office or drop in and we are more than happy to help work out what is needed from your plans. A few rough drawings or sketches with measurements will help the decisions you make in discussions with us.

When working out the volume required, a good standard to remember is: 1 cubic metre covers 10 square metres at 100mm deep (or 4inches). So for the recommended depth of 300mm you will need three times that amount. So 3 x cubic metres of top soil will be required for each area of 10 square metres.

Remember the top soil you choose is there to support your expensive plants over many years. Get the volume right from the start and all you need to do in the future is plant, water, mulch and fertilize.

Caring for your UltraGROW Soil

Soil, like all other aspects of your garden is constantly changing and requires care and maintenance to ensure continued healthy plant growth. There are a number of things you can do to ensure your soil stays healthy, and a regular maintenance program is just as important as the initial soil selection.

The UltraGROW soil range comes jam-packed full of goodness, but remember, over time this goodness will slowly be used up by your plants. So it is important to keep up a regular fertilising regime. There are many fantastic fertilisers on the market to suit all planting applications, but one of the best is Organic Xtra which is now supplied with your UltraGROW soils when purchasing over 1 Tonne. Why not grab an extra bag and keep it in your shed!

One of the most important additions to remember when establishing a new garden bed with UltraGROW soil is the use of a quality mulch or bark.

So why is a mulch so important?

And what will it do to help my garden thrive? Here’s 4 Points worth noting…

      1. MOISTURE CONTROL– This is by far the most important reason for using a mulch. Without a good layer of mulch (100mm or 4”), the sun and wind will cause the top 100mm of garden soil to dry out very quickly putting your plants under extreme stress in a very short space of time. By adding mulch, the rate of evaporation is slowed dramatically and with water restrictions, any saving of water usage can only be beneficial not only to the environment but to our hip pockets too. Often we get complaints that plants are not growing well only to find when we visit that the garden has no mulch resulting in the garden soil drying out and even crusting preventing water penetration.
      2. WEED PREVENTION – Having a physical barrier on top of the garden soil will inhibit weeds. Once a seed germinates and reaches the garden soil surface it needs sunlight to photosynthesize (produce food for growth). If a mulch is in place, just its physical presence will prevent most, if not all, potential weed problems thus allowing your plants to thrive without competition. NB. Don’t use plastic under mulch, it prevents the passage of water and gases into the top soil and therefore this can hinder plant growth. We suggest you use “Weed Stop”.
      3. TEMPERATURE MODERATION– This is another benefit of having this physical barrier. In our Queensland climate, top soil will absorb a considerable amount of heat which in an un-mulched garden causes damage to sensitive plant roots near the garden soil surface. Also in those areas that have mild frosts, the mulch will again moderate the temperature making your garden soil a more “enjoyable” environment for your plants to grow!
      4. REPLACING ORGANIC MATTER – As the mulch decays, it helps maintain its open free draining structure. This can be seen if you walk through any rainforest or bushland where the ground underfoot is covered in decaying organic matter or natures mulch… nature’s way of composting or making a mulch.

This is a very common question and is a valid one considering we at Centenary Landscaping Supplies have over 17 plus to choose from! But when its all said and done, it is true to say that in general, mulch will all do the same job with regards to moisture, weed and temperature control.  In most cases, the buying decision for a mulch can be based on colour, texture and mulch prices to fit your budget.

There are, however, a number of questions that can be asked to narrow the mulch field and help you choose the best mulch for you: And we are here to help you answer those questions…just call 3373 4999 now.

        • Are you matching any other part of the garden with existing mulch?
        • Have you seen a mulch you like at the neighbors?
        • Do you generally like coarse or fine materials as mulch?
        • Is this a show garden, or down the back?
        • Am I just tidying the gardens up to prepare for the house to be sold?
        • Is it a vegetable or herb garden?

Now armed with this information, your UltraGROW Soil and your Organic Xtra Fertiliser we are confident you will achieve fantastic results!

Creating a New Lawn with our UltraGrow Under Turf Soil

Many new lawns are laid on little or no top soil which therefore require a lot of fertilisers and water in the future. To give your lawn the best possible start, lay a 150mm depth of top soil which will act as a water and nutrient reservoir for the turf and ultimately save you dollars. So, how much top soil do you need for 150mm depth? Use this simple formula to determine the volume of soil you need: AREA m2 x 0.15 = Vol m3.

Spring and early summer is an ideal time to top-dress your lawns which will not only level out any lumps and bumps but increase the water holding capacity in the lawns root zone and of course give it a boost of nutrients just when it needs it most.
