I usually buy a bagged potting mix. Can I improve it by using this Potting Mix Recipe?
Absolutely! If you find it convenient to start with a commercially available potting mix, you can always improve the characteristics of this mix. So, for example, you can increase the moisture and nutrient-holding capacity of your regular potting mix. Use the Guide to add some or all the suggested ingredients in this recipe that perform those roles. This will be very useful to stop your bagged mix becoming hydrophobic (repelling water). It can also reduce the frequency you need to fertilise. If your regular potting mix does not contain slow-release nutrients, you can use the recipe to guide you what to add to feed your plants over time.
Does this Potting Mix recipe contain garden soil?
No! This is a soil-less growing medium designed for growing plants in containers with a balance of ingredients that are lightweight, provide excellent drainage, aeration, moisture retention, nutrients and neutral pH suited to growing most plants. It can also be used to plant straight into in raised beds as a solution to poor quality garden soil. The texture and properties of garden soils vary widely so are not generally suitable for container plants. Garden soil may not have the ideal particle structure for optimum drainage, have poor moisture-holding capacity and can contain pathogens, weed seeds and pests. Not what you want to introduce into your pots, especially if you’re growing indoors.
Potting mix is not the same as ‘potting soil’ or ‘garden soil’ which is generally sold as a commercial bagged mix containing a portion of garden soil along with other ingredients like sand and cheap organic material like composted bark and manure. This type of ‘garden soil’ or ‘potting soil’ is better suited to planting into garden beds as it’s a coarser mix.
I’m interested in making my own seed raising mix. Can the recipes in your Guide save me money?
There are 5 recipes you can choose from with low-cost or homemade ingredients, so you can tailor to your own budget using materials you may already have or make easily for free. This allows you to grow a more sustainable garden rather than paying for packaged seed raising mixes, with the embodied energy in manufacturing and transport. You can also sprinkle your own seed raising mix blend into your garden for sowing seeds directly.
Can’t I just make my own seed raising mix by sifting garden soil?
These recipes are soil-less. This ensures no soil pathogens are present that could cause damping off and other diseases that stop germination or healthy seedling growth. Pathogen-free growing media is essential for successful seed raising. By making your own blend, you control the growing environment. So you are more likely to avoid potential problems with soil-based mixes. Predominantly sandy soils won’t hold moisture or nutrients sufficiently. Clay soils may not contain adequate oxygen and air spaces for roots to breathe and can become waterlogged. Customers who have had poor germination previously, have shared their success stories by using the recipes in this Guide.
How was this Guide developed?
This unique recipe, comparison chart and instructions were developed as a result of three years of tried and tested research. It has been endorsed by Australia’s foremost potting mix guru, John Daly who makes commercial potting mix blends for major Australian company brands as well as his own.
