When should I put weed and feed on my lawn?

If you’re wondering when to apply weed and feed to your lawn, you’re not alone. It’s a very common lawn care question and the answer depends on season, weed growth, and the type of product you use. Seasons vary greatly throughout Australia and it is important to use the right weed and feed bundle at the right time.

Weeds need a herbicide designed to kill them. Your lawn needs a fertiliser designed to feed it. Mixing the two together tends to create a compromise.

That’s why a two part weed and feed system (a dedicated herbicide + a concentrated fertiliser) is recommended.

The Best Time to Apply Weed and Feed in Australia

Australia’s climate varies, but the rule of thumb is:

✔ Apply weed and feed when:

• Weeds are actively growing
• Your lawn is not overly stressed
• No heavy rain is forecast for 24 - 48 hours

✔ Avoid applying when:

• The lawn is significantly stressed
• Frost is present or expected
• Soil is waterlogged
• You’ve just mowed (or are about to)

☀️ Warm‑Season Application (Spring & Summer)

Recommended Product: Weed & Feed Bundle

During warmer months (especially September to March) weeds like bindii, clover, oxalis and cudweed grow aggressively. This is the perfect time to use a dedicated herbicide paired with a high quality fertiliser.

The Weed & Feed Bundle is ideal because it includes:

• A professional herbicide designed to target broadleaf weeds
• A concentrated fertiliser formulated to feed your lawn
• Two separate products, meaning each one works at full strength

This approach gives you:

• Effective weed kill
• Deeper green colour
• Stronger root growth
• Longer lasting results

❄️ Cool‑Season Application (Autumn & Winter)

Recommended Product: Lawn Juice Liquid Weed & Feed

In cooler months (April to August) lawns slow down and many granular products become less effective because they rely on plant uptake through the roots.

That’s why a liquid weed and feed bundle is the better choice.

The Lawn Juice Liquid Weed & Feed is formulated to work in cooler conditions by delivering:

• A liquid herbicide that absorbs through the leaf
• A liquid fertiliser absorbed through the leaf to promote colour and growth

This makes it perfect for maintaining lawn health through winter and controlling broadleaf weeds.

🌿 Final Thoughts

You should apply weed and feed whenever weeds are actively growing, but choosing the right product for the season makes all the difference.

• In warm months, use the Weed & Feed Bundle for maximum weed control and lawn nutrition.
• In cool months, switch to the Lawn Juice Liquid Weed & Feed for better absorption.

This simple seasonal approach keeps your lawn greener, cleaner, and healthier all year round.
