Step 1 – Take a stocktake of your garden and lawn

Take a good look around your garden to check the health of your plants and lawn and to see what’s going on and what has been affected. Here are a few things to consider:

  • If a plant has died, remove it to reduce the possible flow-on effects of pests and diseases. Take note of the spot for future planting.
  • Check for burnt foliage to prune when the weather cools. If hot conditions persist, leave pruning until cooler weather arrives to prevent exposing new foliage to burning.
  • Weakened plants are more susceptible to pests and diseases. To prevent problems spreading, remove diseased or pest-affected foliage and stems.
  • Ensure prunings are put in the bin, not the compost. If the plant doesn’t look like it will recover, consider removing it.
  • If the lawn is looking a bit stressed and yellow from the heat and overuse apply Sesaol Organic Iron for Deep Green Lawns to help revitalise, strengthen, and green the lawn. Apply once a month until the lawn improves!

Step 2 – Look at ways to improve your house and garden for next summer

The right plant and lawn selection for your location and climate can be the difference between a garden that flourishes and one that struggles. Following a few tips now and throughout the year can prepare it for the summers ahead.

  • Take note of the plants that are flourishing and love summer. Late in autumn is a good time to divide or propagate these plants as a cheap way to have more summer-tough plants to grow.
  • If you have plants that have survived but are not growing well, they may benefit from being moved to a better location. Do this in autumn or winter.
  • Consider planting drought-tolerant, sun-loving plants to replace those that you have moved. Mediterranean and grey foliage plants such as lavender, olives, rosemary or cacti and succulents perform well in hot summers.
  • Examine a spot in the garden to put a tree to cool the house and provide a shady canopy for future plants. Trees don’t have to be big.
    • For a courtyard or pot on a balcony, consider a citrus, dwarf evergreen magnolia, dwarf flowering gum, Japanese maple, or forest pansy (Cercis ‘Forest Pansy’).
    • For a larger tree check out an ornamental pear, birch, holm oak, compact eucalypt or maple. Warmer climate options include crepe myrtle, poinciana, tulipwood (Harpullia pendula), leopard tree or Cape chestnut.

Step 3 – Soil health.

Soil is the major building block for a vibrant garden, healthy plants and lawn. Having fertile soil ensures moisture and nutrients are available for plants, plus it increases worm and microbial activity. It’s also the first step to ensuring successful autumn planting.

When looking at your soil, rake back the mulch to better see its condition. If you have organic mulch such as lucerne or sugar cane mulch that is beginning to breakdown, incorporate it into the soil then top up with fresh mulch.

Put your hands into the soil to check its condition. It could be very dry and may be hydrophobic (when water is pooling, not going into the soil). Apply a soil wetter such as Seasol Super Soil Wetter & Conditioner to help overcome this.

Apply organic manure and homemade compost and/or Seasol Super Compost to revitalise and add nutrients back into the soil. If your garden is full of plants, use a no-dig option such as Seasol Liquid Compost to avoid root disturbance.

Let the soil rest for a couple of weeks before planting to give all the good things time to get to work to improve the soil.

Step 4 – Autumn Lawn Care

Autumn is the time for lawn recovery and rejuvenation after the heat of summer. It’s time to take a good look at the lawn to see what damage has occurred. As the weather cools and days get shorter, repair and maintenance are key activities.

  • Maintenance As the weather cools, it’s a great time to repair your lawn, with aeration, sowing seeds or planting runners to fix bare patches, or improving lawn and soil health with Seasol Lawn + Soil Booster.
  • Irrigation Water the lawn based on the weather conditions. Early autumn may still be hot so lawns still require extra water. As the weather cools, less water will be required. Check the lawn and soil and water as needed.
  • Feeding Autumn feeding is important as the grasses resume growth in response to milder conditions and rain. Apply Seasol for Lush Green Lawns or Seasol for Buffalo Lawns to revitalise lawns and promote strong, lush green growth.
  • Mowing Continue to mow the lawn with the blades raised to leave extra leaf blade to help with photosynthesis (the green lawn’s natural ability to make nutrients) and to protect the lawn’s root system while it’s still hot.

Step 5 – Autumn plant care

Autumn is about improving plant health and feeding plants. Early autumn may still have hot conditions, but it will cool down as the season progresses.

Plants may be suffering after the stresses of summer or thriving if summer was kind in your part of the world. Whatever their condition, improve and strengthen plant health with regular fortnightly applications of Seasol applied via a watering can or hose-on.

Clean up the garden by deadheading summer flowers and harvest the last of the edible produce. Don’t leave produce on plants once it is ready to harvest, as this can stress plants, soils and produce tasteless crops.

Look after summer-flowering bulbs by allowing them to die back naturally after flowering. Apply a granular fertiliser such as Seasol plus Nutrients for Roses and Flowers to feed next summer’s flowers and growth.

Prune back overgrown foliage, especially around pathways and driveways, remove diseased and damaged foliage and give your plants a gentle feed with Seasol Advanced hose-on to strengthen plants for autumn growth.

Step 6 – Autumn pot plant care

Plants in pots have different stresses from those in garden soil as they can’t send their roots out for moisture and nutrients. Autumn is a great time to rejuvenate potted plants.

  1. Take indoor plants outside on a cool day and give them all a good spray with a soaker spray to remove dust and dirt.
  2. Check potting mix as it may have reduced in volume over summer. If the plant has become too large for the pot, repot it into a larger pot using a premium potting mix such as Seasol Advanced Potting mix. Check out our successful pot planting guide for more tips.
  3. If the potting mix is in good condition, revitalise it with the addition of the beneficial microbes in Seasol Potting Mix Booster.
  4. Prune back damaged and diseased foliage and deadhead any flowers. Wipe leaves and apply EarthCare White Oil insect spray as a leaf shiner and to protect against pests.
  5. Give all the plants a liquid feed with PowerFeed Indoor & Potted Plants spray for lush foliage, beautiful blooms and tasty produce.

TIP: Reposition your potted plants into their ideal autumn position as the weather cools. Move outdoor plants slowly into a sunnier position and move indoor plants closer to a window for more light and heat.

Step 7 – Gardening tips for autumn

Autumn is the perfect time to brighten up your indoor and outdoor space with lush new foliage plants, bright flowers and tasty autumn produce. Whatever the space, try one of these:

  • If there is a dull spot in the house, why not add a new indoor plant or plants if there’s plenty of space. A new indoor plant buddy will add vibrant colour and make you feel good.
  • Plant colourful annuals such as viola, pansy, lobelia, sweet pea, alyssum and calendula in pots and garden beds around outdoor entertaining spaces, balconies and pathways for autumn and winter colour.
  • Plant the autumn vegies you love to eat in the vegie patch or a large pot. Delicious options to grow now include English spinach, silverbeet, beetroot, onions, kale, broccoli, cauliflower or lettuce. Feed regularly with PowerFeed PRO SERIES for Tomatoes & Vegetables. For all you need to know about growing different vegies check out our vegie guide.
  • Clean up around the garden, check gutters and remove debris, wash down decks and outdoor furniture and add a splash of colour with new cushions.
  • Clean the garden shed, recycle or clean old pots, check on fertilisers and potting mix and clean and maintain gardening tools, especially pruners for autumn pruning jobs.
