Lawn recovery in March: bare patches, scarifying and first feeding

TL;DR

March is the ideal month for lawn recovery: grass starts to grow, soil warms up, and seeds germinate well. First check where you have bare patches and dead spots. Scarify (rake out dead organic matter), overseed bare patches with grass seed matching your existing lawn, apply spring feed (nitrogen-rich), and water regularly over the coming weeks. A lawn you tend in March grows thick and lush all season. Upload your garden photo to [gardenworld.app](https://gardenworld.app) to see how a healthy lawn fills out your front yard.

Why March is ideal for lawn recovery

March is biologically the perfect moment. Soil temperature rises just above 8 degrees Celsius, which is the awakening threshold for most grass species. Winter damage (frost, snow, fungal disease) begins to lift, and grass grows actively again. This is when your recovery work has maximum impact.

Moreover: moss and weeds are also just waking up, so you want to make your grass stronger than them so the grass wins. A lawn you recover now grows stronger than moss and weeds all season.

Finally: lawn recovery in March saves time. If you wait until April or May, you have far more mowing and trimming ahead. Professional gardeners start lawn season in March.

Step 1: Inspection - where are the problems

Walk your lawn on a sunny day in March. Look for:

• Bare patches: Complete dead earth without grass
• Thin grass: Areas where grass is very sparse
• Moss patches: Green mossy areas
• Compaction: Spots where water pools (poor drainage)
• Dead grass: Dark brown, dead areas from winter damage

Make a quick map or photo with notes. This helps prioritise.

Step 2: Scarify - remove the dead

Scarifying means pulling dead grass and moss litter from your lawn. This is done with a scarifier (rental machines available at most garden centres) which drags sharp tines along the ground.

Why is this important? Winter causes a buildup of dead grass plants on top of living roots. This "thatch" or organic debris layer stops water and oxygen penetrating. By mechanically removing it, your grass breathes again.

How to scarify:

1. Mow your lawn very short (2-3 cm) before scarifying.
2. Scarify in one direction, then opposite direction (criss-cross). This pulls out more dead matter.
3. Do not scarify too deep - tines should just penetrate the thatch layer, not damage roots.
4. Rake up all loose material and compost it.

After scarifying, your lawn looks rough. This is normal. Your lawn recovers in 2-3 weeks.

Step 3: Overseed bare patches

Once you have scarified, overseed the open patches. This is crucial: bare earth attracts weeds. Fill those gaps with grass and we prevent weeds.

Which seed to choose:

• Look at your existing lawn: Is it fine and dark green? Choose "Premium Sport" or "Sports Grass"
• Is it coarse and pale? Choose "Wildflower" or improved grass blends
• Garden centres stock mixes suited to different lawn types. Ask for advice.

Seeding:

1. Loosen the bare patches with a rake (5 cm deep)
2. Sow seed densely (25-30 grams per square metre)
3. Work seed lightly in with the rake
4. Roll (press down gently) so seed contacts soil
5. Water well, keep moist over the coming 3-4 weeks

Seeds germinate in 10-14 days if kept warm and moist.

Step 4: Address drainage and compaction

If you have spots where water pools (especially after rain), you have a drainage problem. This can be from compaction (too much foot traffic) or clay soil.

Light compaction:

• Aerate lawn with a garden fork or rental aerator
• Makes holes so water and air penetrate better
• Do this in March when soil is still soft

Heavy clay:

• Work sand through your lawn (1-2 cm over entire area)
• This gradually improves drainage
• Repeat for three seasons for maximum benefit

Step 5: First spring feed

After scarifying and seeding, your grass will grow vigorously. Give it the nutrition it needs.

Choose a nitrogen-rich spring feed (e.g. 20-10-5 NPK ratio):

• Nitrogen (N) stimulates leaf growth and green colour
• Phosphate (P) supports roots
• Potassium (K) strengthens the plant

Apply feed in early March (first two weeks), ensuring even distribution. Many gardeners use a spreader for even coverage.

Water well after feeding so nutrients dissolve and penetrate the soil.

Step 6: Regular water and mowing schedule

Over the next 4-6 weeks, regular watering is crucial:

• First week after seeding: water lightly daily
• Weeks 2-4: 2-3 times per week
• After month 1: as grass strengthens, less frequently

Mowing schedule:

• First cut: When grass reaches 8-10 cm, mow to 5-6 cm
• After that: Mow weekly during active season, to 4-5 cm
• Not too short: Short grass stresses and invites moss

Step-by-step

Step 1: Inspect your lawn

Walk around and note bare patches and problems.

Step 2: Scarify

Rent scarifier, mow short first, scarify in two directions, rake off.

Step 3: Seed bare patches

Loosen earth, sow grass seed, roll gently, water well.

Step 4: Improve drainage

Aerate with fork or spread sand if needed.

Step 5: Feed

Apply spring feed, water in.

Step 6: Water and mow

Water regularly for first 4-6 weeks, mow when grass reaches 8-10 cm.

Frequently asked questions

Can I scarify and seed on the same day?

Yes, this works and is actually ideal. Scarify first, rake off, seed immediately after. The open patches are then perfect for germination.

How much seed do I need for my lawn?

Roughly 25-30 grams per square metre for overseeding (for complete renovation you need more). A 10 kg bag of grass seed covers substantial area.

My lawn was full of moss - what now?

Scarifying removes much moss. Then: ensure grass grows stronger (feed and water) than moss. Moss thrives on waterlogging and weak grass. A strong lawn displaces moss naturally.

Can I use chemical moss killer?

Yes, but far less effective than strengthening the grass. Chemicals kill moss but do not address the cause (poor drainage or weak grass). Better: fix the lawn itself first, chemicals are secondary.

How long until my lawn recovers?

6-8 weeks. Newly seeded grass reaches full cover in weeks. Existing grass recovers in 2-3 weeks after scarifying. By late April you have a renewed lawn.
