The secret to thriving plants in spring is healthy soil - and autumn is the perfect time to give it some TLC. 

Like a chef blends ingredients to create a delicious balance of flavours, soil prep is all about getting the right mix of nutrients to create great growing conditions for plants.

Based on a one square metre area, the below is a step-by-step recipe for soil success. For best results, this recipe is best prepared and left to simmer for at least one week before planting.

The first step to perfect spring soil prep is digging out weeds and unwanted plants plus breaking up soil clumps in your chosen area.


Recipe for soil success

Step 1: Prepare your garden bed by removing unwanted plants, weeds and stones, breaking up clumps of soil as you go. This will also help to aerate the existing soil.

Step 2: If your soil needs a top-up, grab some fresh garden mix. If you're working with a small space or don't need to add too much to your existing soil, a great bagged option is Brunnings Naturally Good Garden Soil. For larger areas, our bulk garden mix is your best friend - we've got organic and premium options to suit every garden.

Step 3: Dig in half a bag of soil additive like Supersoil Garden Compost.

Step 4: Mix in two handfuls of Blood & Bone Based Fertiliser to give plants an extra boost. Skip this step if planting natives and flowering exotics such as rhododendrons as it may be too strong.

Step 5: If you have clay soil, add gypsum.

Step 6: Rake your garden bed to ensure the soil is level.

Step 7: Plant your new additions, ideally at least one week after preparing soil.

Step 8: Spread an even layer of Organic Sugar Cane Mulch to a depth of 5cm.

Step 9: Water your newly-planted additions deeply with a Seaweed Concentrate - you can add it to a watering can or use a hose-on pack. This will act as a health tonic and help them to establish well in their new home.

Step 10: Finally, spread a handful of Supergrow Organic Fertiliser Pellets across the surface to feed your new plants.
