Doff Patch Fix Plus 800g

Doff Patch Fix Plus 800g is an all-in-one lawn patch repair mix that combines grass seed, coco coir and a starter feed in a single bag. The coco coir acts as a growing medium that holds moisture around the seed, while the feed gives the new grass the nutrients it needs to establish quickly. The result is a hard-wearing, low-maintenance lawn that knits into your existing grass without leaving obvious bare spots behind.

Whether you've got dog patches, wear marks from the kids' football games, or thin areas where moss has been raked out, Patch Fix Plus is designed to repair up to 25 patches of around 20cm diameter from one 800g bag. The formulation is fast-germinating, so you'll see green shoots in days rather than weeks, and the resulting turf is tough enough to handle the high-traffic areas of a family garden.

Where to Use

• Bare patches in the lawn — thin or dead spots where grass has failed to establish.
• High-traffic areas — patches worn thin by footfall, children playing, or regular walking routes.
• Pet damage — yellowed or bare spots caused by dog urine and digging.
• Post-moss or post-thatch — areas where moss or thatch has been raked out and need re-seeding.
• After weed removal — thin or patchy areas left behind after weeding.

How to Use

• Prepare the patch: rake out any dead grass, moss or debris so the soil is loose and level. For compacted ground, lightly fork over the top 2–3cm.
• Water the area first: dampen the soil so the seed has moisture to start with.
• Spread the mix: sprinkle Patch Fix Plus evenly across the patch to a depth of roughly 5–10mm, covering the bare soil completely.
• Firm down gently: press the mix into the soil with the back of a rake or your foot so it makes good contact with the ground.
• Water in: give the area a thorough but gentle watering. Keep the patch moist (not waterlogged) for the next 2–3 weeks while the seed germinates.
• First mow: wait until the new grass is at least 5–7cm tall before mowing, and set the blades high for the first cut.

Key Features

• 3-in-1 formula: grass seed, coco coir growing medium and starter feed in one bag.
• Repairs up to 25 patches of approximately 20cm diameter per 800g bag.
• Fast germination — formulated to sprout and establish quickly, even in cooler UK conditions.
• Coco coir base — holds moisture around the seed and protects it from birds and dry spells.
• Hard-wearing results — produces a tough, resilient lawn that handles regular foot traffic.
• Knits into existing grass — blends with the surrounding turf for a seamless finish.
• Low maintenance — once established, the new grass requires no special aftercare.
• Easy to apply — no special tools needed; just rake, sprinkle, water and wait.

Frequently Asked Questions

How long does Doff Patch Fix Plus take to grow?
You should see germination within 7–14 days, depending on soil temperature and how consistently the patch is kept moist. Full establishment typically takes 4–6 weeks.

When is the best time of year to use it?
Spring, summer and early autumn are ideal — any time the soil is above 8°C and there's no frost forecast. Avoid sowing in the middle of a heatwave or during prolonged dry spells.

Do I need to cover the patch after applying?
No covering is required. The coco coir in the mix holds moisture around the seed and helps protect it from birds. Just keep the area watered.

Can I use it on shaded areas?
Yes — Patch Fix Plus will establish in partial shade, though germination will be slower than in full sun. For heavily shaded patches, a shade-tolerant seed mix will give better long-term results.

Is it safe for pets and children?
Once the product has been watered in and the area is dry, it's safe for pets and children to use the lawn as normal. Keep pets off the freshly sown patches until the new grass is established.

Will the new grass match my existing lawn?
The hard-wearing ryegrass-based mix blends well with most UK family lawns. For best results, overseed the surrounding thin areas at the same time so the whole lawn thickens up together.
