Keeping It Healthy: Overseeding - How and when to over seed your lawn.
Overseeding should follow scarifying of a tired lawn.
Topping up bare patches or giving your grass a boost is what it’s all about.
Best time: September as an Autumn renovation job.
Next best: April or May as a Spring renovation.
How to do it
Mow the lawn as usual.
Your lawn should be scarified to remove dead grass and thatch so you can see the soil beneath.
Using the correct seed mixture and the correct amount.
Sow by hand: - apply seed mixed with coarse grained sand.
Or by seed spreader: - apply seed first then topdress with coarse sand.
How much do I need?
Once the seed is sown avoid walking on the grass as much as possible.
Continue to mow at the usual height when needed, seedlings will continue to grow even with a bit of disturbance from mowing.
Apply an Autumn/Winter fertiliser or a spring/summer fertiliser.
