Hi @kimjay
You're absolutely right not to apply weed and feed products to your newly laid turf! Using chemical weed killers on lawns under six months old can seriously damage or kill the grass while it's still establishing its root system. Your caution here shows excellent gardening instincts, and waiting until next spring will give you much better results.
Why New Turf Needs Special Care
The issue you're facing is incredibly common with newly built properties, especially those constructed on derelict sites. Builders rarely prepare the ground properly for turf laying, often simply rolling it out over disturbed soil that's packed with dormant weed seeds. Once these seeds get moisture and light, they germinate alongside your new grass, creating the weed explosion you're experiencing.
Manual Techniques for Immediate Action
For now, focus on manual removal techniques that won't harm your established lawn. Hand weeding is your best friend here, particularly for the larger perennial weeds like nettles, dock, and dandelions. These are easier to remove when the soil is moist, so tackle them after rain or watering. For bindweed, carefully untangle the stems and follow them back to the root system, removing as much as possible without disturbing the grass roots.

Strategic Mowing to Suppress Weeds
Lowering your mowing height temporarily can help suppress many of these weeds whilst your grass establishes. Most weeds hate regular cutting, and frequent mowing at a lower setting will weaken annual weeds significantly. However, don't go too low as this can stress your new turf. Aim for around 2cm height and mow little and often rather than cutting large amounts off in one go.
Building Long Term Lawn Health
The key to winning this battle is establishing a thick, healthy lawn that can outcompete the weeds naturally. Ensure your new turf gets adequate water during dry spells, as stressed grass is more susceptible to weed invasion. Once your lawn is six months old, you can start a proper feeding programme that will help the grass grow more vigorously and crowd out unwanted plants.
Spring Strategy for Established Lawn
Come next spring, you'll be able to use selective lawn weed killers and weed and feed products safely. This is when you can really tackle the persistent perennial weeds that survive winter. Apply these products when the weeds are actively growing in April or May for best results, followed by overseeding any bare patches where weeds have been removed.
Border Management
Don't forget about that 20cm border strip around your fence. This area will likely need to be completely cleared and replanted, as it's probably acting as a weed reservoir that's seeding into your lawn. Consider installing a proper edge between lawn and border to prevent future weed migration.
