Autumn in Australia is the perfect time to be fertilising your garden.  The cooler temperatures and warm soil make great growing conditions for all those winter vegetables.

Keeping your garden well-fed and nourished is essential to help you grow healthy and thriving plants. Happy, healthy, well-nourished plants are more resistant to pests, diseases, heat stress and frost. Fertilising the garden is easy to do, but you need to apply the right fertiliser for your plants at the right time of the year.

What is the best fertiliser to use in Autumn?

Autumn in Australia is a glorious time to be out in the garden. The mild conditions create a great combination of cooler air temperatures and warm soil for root growth. It is ideal to fertilise your garden to encourage your plants to keep growing.

Vegetables & Herbs:

Apply a generous layer of OCP Eco-Aminogro to your garden beds to prepare and replenish your soil for winter vegetables.  It is also a good idea to check your soil pH with the Manutec Soil pH Test Kit and neutralise the pH if needed.

Fruit Trees:

The top four key jobs for your citrus this Autumn is

  • Feed regularly
  • Consistency with the soil moisture
  • Control pests & prevent/manage disease
  • Protect from birds and possums

Feeding Citrus Trees in Autumn

Regularly feeding your citrus is essential – they’re very hungry plants!  Apply Yates Thrive Citrus Liquid Plant Food every 1-2 weeks to give your citrus the nutrients they require to produce a bounty of fruit.

Soil Moisture for Citrus Trees

Did you know that citrus trees have a very shallow root system causing them to dry out quickly.  Apply Seasol Super Soil Wetter and Conditioner specifically around the root zone and add a layer of mulch to help retain the moisture.

How to Get Rid of Citrus Pests

Use Yates Nature’s Way Citrus & Ornamental Spray regularly that will control aphids and scale, and help to prevent Citrus Leaf Miner damage

Possums, birds and rats like to feed on ripening fruit.  Protect your citrus trees with Ryset Wildlife Friendly Bird Netting to prevent the fruit being damaged.

Laying Lawn Turf

Lay turf when the Autumn rains arrive.  Start with removing any weeds and apply a good layer of OCP Eco Seaweed crumble to prepare the soil.  This will give the new roots of your turf the TLC they need to become established.  Water in the new turf.

Lawn Weed Control in Autumn

Early autumn is a good time to scarify your lawn, capitalising on both the weather and the conditions of the ground. Scarifying / de-thatching removes any thatch, moss, and other organic matter from a garden surface that can prevent water and air from getting into the soil.

When the Autumn rains arrive, feed all natives OCP Eco Seaweed to help promote healthy, new autumn growth.

Indoor Plants:

Give your plants a “spring clean” twice a year.   Give the leaves a wipe with a wet cloth.  This will remove any dust that will be blocking the tiny holes in the leaves and will help them breathe.   A quick spray with Yates Leaf Shine Spray that will clean them and protect them from dust.

Don’t try this with hairy-leaved plants — they generally don’t like water sitting around on their leaves.

Top up the plant’s nutrients with Munash Seaweed Tonic every 2 – 4 weeks.
