Product Overview

iGrow Carpet Summer Advance 15-0-10 + 2% MgO

A controlled-release summer fertiliser that keeps your lawn thick, dark green and growing steadily through the warmest months. Iron free, so no orange staining on paths or drives. Safe for kids and pets when used as directed.

The science bit

Nitrogen (15% N)
Powers steady, lush green growth through summer. Drives photosynthesis and keeps your lawn looking its best when it's under the most pressure.

Phosphorus (0% P)
Deliberately excluded. Phosphorus moves slowly through soil and isn't needed by established grass in summer.  We've left it out and focused on what your lawn actually uses.

Potassium (10% K)
Helps your lawn hold moisture during dry spells and recover quickly from drought stress, keeping colour vibrant for longer.

Magnesium (2% MgO)
Fuels chlorophyll production, giving you a deeper, richer shade of green without the staining you get from cheaper iron-based products.

How To Apply Our Fertiliser

  1. Measure your lawn using our lawn measurement tool
  2. Set your spreader as per its instructions
  3. Use a spreader for even coverage — do not apply by hand
  4. Do not apply in frost
  5. Keep children and pets off the lawn during and after application until watered in and dry
  6. Apply at 30 grams per m² for best results (the product can be applied at between 25-35g per m²)
  7. Blow or brush any product off hard surfaces afterwards
  8. Water in thoroughly for 15 to 20 minutes, or leave if at least 20 minutes of steady rain is forecast within 24-48 hours. The sooner it's watered in, the faster it gets to work

Want to get the best results? Our free Beginners Guide to Fertilising Your Lawn covers everything from spreader settings to professional application techniques.

Q: When should I apply it?

June to August. Avoid applying during a heatwave or drought as you should wait for a cooler spell or before rain.

Q: How much do I need?

Our fertiliser can be applied at 25 to 35 grams per m². We recommend 30 grams per m² as the ideal rate as it gives great results while allowing for a little overlap around edges. Use our lawn measurement tool on the website to calculate exactly how many bags you need based on your lawn size.

Q: How quickly will I see results?

4 to 7 days after it's been watered in.

Q: What's the best way to water it in?

We recommend using a sprinkler as depending on your water pressure, a 15 to 20 minute soak is enough to get the product working. If rainfall is forecast within the next 48 hours that will also do the job, as long as it's not just a light shower.

Q: Will it stain my patio or driveway?

It shouldn't as our granular products are iron free. That said, it's always best to brush or blow any product off hard surfaces before watering in, just to be safe.

Q: How long does it last?

10 weeks in normal conditions. If there's been little rain and slow growth it can stretch to 12 weeks.

Q: Can it burn my lawn in hot weather?

Not when used as directed. Water it in within 48 hours of applying.

Q: Do I need a spreader?

Yes as a spreader gives you even coverage and prevents patchy results. Hand spreading isn't recommended.

Q: What spreader setting should I use?

This varies by spreader model and walking speed. We have a quick start guide on the learning hub.

Q: Can I apply it in the rain?

Light rain after applying is fine and will help water it in. Avoid applying just before very heavy rain as it can wash the product off the lawn before it has a chance to work.

Q: What if I accidentally over-apply?

Water the area thoroughly straight away to dilute the product and reduce the risk of any scorch.

Q: Can I apply it to a newly seeded lawn?

Yes, but also check out our Pre-Seeder which is specifically designed to give new seed the best possible start.

Q: Is it safe for kids and pets?

Yes, once watered in and dry. Grazing pets like rabbits and guinea pigs should be kept off for two weeks or three cuts, whichever comes first.

Very straightforward to use and with the desired results. The YouTube video series was excellent at explaining the best was to approach the job of spreading such fertiliser and being new to the lawn care scene they were much appreciated.

We built that video into a full course, its on the learning hub. Once you learn how to do it properly, it makes such a difference to your lawn!

Really looking forward to using it, got to calibrate my Einhall spreader that I bought from one of your other videos. I’ll come back to you in the near future. Thank you. Alan.

I have delays my annual renovations because it has been so dry and hot. I opted to go for this fertiliser instead of the spring version as this is summer weather. I was lucky in that it rained for three days after putting this down. Excellent product and you can definitely see where I missed areas. One obvious point - make sure you set your spreader up properly as the grains are pretty small and it would be easy to blast through a bag and overdose. Excellent product and will buy again.

Hi Anthony
Thanks for the review!
Good shout on the spreader settings, getting that calibration right is key for perfect stripes/
Since you mentioned missing a few spots, you might want to check out our free lawn feeding course on our website. It has a breakdown on how to get perfectly even coverage so you don't get those missed stripes next time.
Thanks again for the support!

Worked like a dream. Went away for two weeks & came back to very brown patches of grass. Mowed high, fertilised & watered after. One week later the grass is nearly back to normal. Very lush & very green.
