🍁 Autumn Lawn Care Canberra: FAQ Guide

Q1: What autumn lawn care steps should I take in Canberra?

A: Autumn is key to rebuilding after summer stress and setting up for winter. Key actions include:

  1. Aerate to relieve compaction and improve water and nutrient uptake. Core aeration is optimal now.

  2. Fertilise with a slow-release, potassium-rich blend to strengthen roots.

  3. Dethatch if thatch exceeds 1 cm, using a power rake or fork.

  4. Overseed patchy spots after aeration and dethatching for a denser lawn.

  5. Top-dress with a fine soil blend to smooth the surface and boost root zones.

Q2: When should I apply pre-emergent weed control in autumn?

A: Ideal timing is early to mid-autumn, before winter weed seeds germinate. Pre-emergents like Oxafert create a protective barrier for up to 12 weeks. Avoid overseeding in treated areas to ensure seed germination isn’t blocked.

Q3: How should I adjust mowing practices in autumn?

A: Gradually increase mower height to 5–7 cm to protect grass from cold and shade. Keep mowing regularly to remove leaves and prevent smothering, using mulching to recycle nutrients into the soil.

Q4: How much should I water during autumn in Canberra?

A: Water only when needed (usually once or twice a week with 10–15 mm) due to cooler temperatures and occasional rainfall. Use soil moisture tools or manual checks to avoid overwatering.

Q5: Is autumn a good time to lay new turf or reseed?

A: Absolutely. Cooler temperatures support root establishment without heat stress. Prep the soil, apply starter fertiliser, and water lightly but consistently until the turf roots firmly.

Q6: What turf type considerations are relevant in autumn?

A: Use warm-season grasses like Kikuyu, Buffalo, and Couch; autumn is their growth finale before dormancy. For cool-season lawns (e.g., Ryegrass), autumn is a peak period for growth; mow lower to encourage sunlight penetration.

Q7: How do I prevent pests and weeds in autumn?

A: Autumn brings weeds and pests; tackle them before they establish.

  • Use selective herbicides early to control bindii, oxalis, and clover.

  • Watch for early signs of grubs or armyworms and treat reactively after summer exposure.

Q8: Should I use wetting agents or soil conditioners in autumn?

A: Yes, wetting agents reduce surface runoff, allowing better moisture absorption. Soil conditioners improve structure and prime your lawn for winter.

Q9: Is it safe to prune trees and shrubs in autumn?

A: Yes, pruning improves light access, prevents leaf debris from accumulating, and reduces shade on the lawn.

Q10: What special maintenance tools are recommended in autumn?

A:

  • Mechanical core aerator or garden fork for aeration

  • Spike roller to prepare for overseeding

  • Fine-blade mulching mower for precise leaf and grass cutting

  • Soil moisture meter to guide watering decisions

Using quality tools ensures efficient, effective autumn care.
