Short answer: Colour doesn’t equal growth. Lawns can stay green while growth slows if roots and soil biology aren’t functioning properly.
This happens a lot in lawns that are regularly fertilised but exposed to heat, compaction or repeated stress.
What’s really going on
Fertiliser can boost leaf colour without improving what’s happening below the surface. If soil is compacted or biologically inactive:
• Roots struggle to develop
• Nutrients aren’t accessed efficiently
• Growth stalls, even though the lawn looks healthy
Why more fertiliser doesn’t help: Growth depends on root activity and soil processes, not just nutrients. When soil function drops, fertiliser delivers diminishing returns.
What helps instead
Long-term improvement comes from:
• Supporting beneficial soil microbes
• Improving root–soil interaction
• Allowing the lawn to grow naturally, not just green up
Where a plant probiotic fits: A product like Naturalift supports soil biology, helping lawns access nutrients already present and recover more consistently during stress.
Takeaway
If your lawn looks good but won’t grow, the issue is usually below ground. Fix the soil system and growth follows.
