Keeping your lawn lush, green, and weed-free doesn’t have to break the bank but it helps to know what you’re working with. In 2025, the cost of lawn weed and feed treatments varies widely, depending on whether you’re a DIY enthusiast or prefer calling in the professionals.
In this blog, we’ll break down lawn weed and feed cost, what you’re really paying for, and how to get the best bang for your buck so you can enjoy a healthy, thriving garden without overpaying.
DIY vs. Professional: What’s the Cost Difference?
If you’re happy to get your hands dirty, DIY weed and feed products are a great money-saver. On average:
- 10–15kg lawn feed bags cost between £25 and £35
- Covers up to 700m², depending on the brand
- Works out around 4–6p per square metre
But if you’d rather leave it to the experts, professional lawn treatment services (like us at Lawn & Gardens Sussex) charge around:
- £45 per visit for a standard lawn
- Monthly maintenance plans starting from £15 per month
- Tailored to your lawn’s needs fewer mistakes, faster results
Pro tip: Bulk-buying your feed or booking seasonal packages can save up to 25% compared to one-off purchases.
What Affects the Price of Weed & Feed?
Several things determine what you’ll pay whether you’re doing it yourself or hiring someone in:
1. Lawn Size
The bigger the garden, the more product you’ll need. For example:
- A 100m² lawn may only need 4kg of feed
- A 500m² lawn could need up to 20kg
2. Lawn Condition
Got moss? A thick weed invasion? You’ll need stronger solutions or repeat treatments which can drive costs up.
3. Product Type & Quality
Premium brands cost more, but they often work faster and last longer. Some even come with moss killer and growth boosters in one.
Popular 2025 UK lawn feed products include:
- A1 Lawn Double Strength Weed & Feed (10kg) – ~£30
- Greenforce Moss Killer & Feed (15kg) – ~£34
- Elixir Complete Lawn (20kg) – ~£55
.
Is It Worth Paying More?
Absolutely, if it means your grass grows faster, greener, and weed-free. Here’s why spending a little extra can pay off:
- Stronger feeds often mean fewer applications
- Combined moss killer and feed saves time
- Hiring a pro might cost £180–£250 per season, but includes expertise, time savings and stronger formulas
According to Checkatrade, most homeowners in the UK spend around £200 annually on lawn care, including weed and feed.
How to Cut Costs Without Sacrificing Quality?
Here are a few money-saving tips:
- Apply feed in spring and early autumn when grass is growing strong
- Use a spreader for even application and no waste
- Aerate and scarify first helps nutrients reach the roots
- Combine feed with water if it’s granular better absorption
- Book seasonal packages with your local gardener

When’s the Best Time to Apply It?
Timing matters! For the best results:
- Spring (March–May): Kickstart growth and knock out early weeds
- Autumn (September–October): Strengthen roots before winter
- Avoid frosty or bone-dry days, and always follow product instructions
FAQs
1. How much does weed and feed cost per m²?
Roughly 4p–6p/m² for DIY products. Hiring a professional? Expect 20p–25p/m² including service.
2. Can I apply it more than twice a year?
Yes, but space out treatments by 6–8 weeks to avoid overfeeding or burning your lawn.
3. What’s the cheapest way to treat weeds?
Use iron sulphate for moss (~£6 per kg) and spot-treat weeds with a selective herbicide. It’s cheap, but takes effort and know-how.
4. Is lawn feed safe for kids and pets?
Once it’s watered in and dried, most lawn feed is safe. Always check the label or opt for pet-safe versions.
