Gardening Tips for Autumn 2021

Autumn in our climate is short – typically starting early April and extending into May. This time of year is a LOT more comfortable to enjoy your garden than our long hot summer from December to March. With lower humidity and cooler temperatures, many pest insects exit stage left and there are so many more plant varieties you can grow.

 

April and May are prime planting times for our autumn and winter crops. We only have short seasons during autumn and winter (June/July) so it’s best to make the most of them. That means getting your timing right and being prepared to plant ASAP! Pests and disease problems are minimal so why not take advantage of nature’s window and get planting?

To enjoy a continuous harvest rather than feast or famine, aim to ‘sow little and often’. A technique called succession planting. By sowing a few seeds or seedlings every week or two, you are planting an ongoing supply of fresh ingredients. 

With recent rain, the soil should have a good reservoir of moisture. Perfect for transplanting seedlings and fruit trees. Pre-soaking in liquid seaweed first helps minimise transplant shock and boosts nutrients. If you’ve missed out on moisture in your garden, make sure it is watered well prior to and after planting. 

Preparing for Planting 

With all the summer growth, there are plenty of plants and grass clippings to provide free organic matter to make compost. Chop and drop weeds without seeds, arrowroot, comfrey, prunings, old pumpkin or cucumber vines and other unwanted plant material. Turn this ‘green waste’ into nutrient-rich healthy soil to feed your garden. 

Re-grow free plants from kitchen scraps or recycle as compost ingredients. Tired depleted soil won’t grow healthy plants, so prepare your pot or plot first. Learn how with 3 simple steps. 

What to Plant Now

 

All your leafy greens will do well as temperatures and humidity drop. Lettuces, kale, coriander (yes, it’s finally cool enough to sow those seeds), rocket, silverbeet, rainbow chard, Asian greens and celery to name a few. Grow these herbs and leafy vegetables as microgreens for fresh fast ingredients too. 

A few other crops to consider include: Peas (who can live without them?), beans, broccoli, cabbage, capsicum, cauliflower, eggplant, leeks (ready just in time for soups), nasturtiums, pineapple sage, spring onions, strawberries, zucchini and most herbs including dill and borage. Sow flowers like sweet peas, marigolds, calendula, cosmos and viola for colour and pollinators. 

If you haven’t yet sown your seed potatoes or garlic, wait until a root crop day for best results and prepare your soil well now. Both these crops do best in soil rich in nutrients (plenty of compost) and mulch

What to watch out for 

Aphids, QLD fruit fly, slugs and snails (they love the wet) and you may start to see white cabbage butterflies. 

Happily, you should expect to see grasshopper numbers start reducing as the temperatures become cooler! 

Remember a healthy garden ecosystem includes a BALANCE of pests to predators. i.e. pest insects are part of a food chain and you need more predators than pests! Plant flowers to provide nectar and pollen for bees, pollinators and beneficial predator insects. Many of these predators rely on nectar as a food source as adult insects, but their larvae eat pests like aphids and scale. Hoverflies and ladybirds are a couple of examples. 

Garden Tasks this Month 

  • If you haven’t yet mulched your garden or potted plants, do so now. Hold valuable moisture IN for the growing season. Rainwater is rich in nitrogen whereas town water contains chlorine and fluoride chemicals that build up in the soil. 
  • Fertilise citrus and fruit trees if you haven’t already. New season fruits and flowers place a high demand for nutrients on your trees. Topping up the soil ‘pantry’ ensures you will 
  • have a bountiful harvest of sweet juicy fruits. 
  • Harvest your basil and make pesto before it sets seed, or save seeds for spring planting. 
  • Prune and remove summer crops that have finished. Use in compost, liquid feeds or as mulch.
