Grass Seed

How To Grow Grass Seed - Beginners Guide

When Do I Sow A New Lawn?

If you want a fantastic lawn, but don’t want the expense of buying turf, sowing a lawn yourself is a great option not to mention extremely rewarding.  Grass seed germinates most effectively in mid-spring and early autumn. The soil tends to be warm, there’s enough moisture and the weather is neither too hot nor too cold. Please ensure the ground is free from frost as this will rapidly decrease germination.


How Do I Sow A New Lawn? 

  • Prepare the soil by removing any weeds, moss, stones and other debris.

  • Add topsoil if think the current soil is of poor quality or if you need to level out your lawn.

  • Rake over the site to leave a level and fine finish seedbed.

  • Three to five days before you sow the grass seed, lightly rake in our Pre-Seed Fertiliser to encourage growth and root development.

  • Sow the seeds at the recommended rate of 50g per m2.

  • After sowing, lightly rake over the area.

  • Firm down the seedbed by foot or by using a roller to improve contact between seeds and soil.

  • Give your newly sown seeds a good watering.


How Do I Overseed an Existing Lawn?

  • Scarify your lawn to remove any dead grass, weeds and moss.

  • Ensure the soil isn’t too compact by raking the area sufficiently.

  • Three to five days before you sow the grass seed, lightly rake in our Pre-Seed Fertiliser to encourage growth and root development.

  • Sow the seeds at the recommended rate of 35g per m2.

  • Make Sure the seeds are amongst the soil by raking the area.

  • Firm down the seedbed by foot or by using a roller to improve contact between seeds and soil.

  • Give your newly sown seeds a good watering.


Aftercare

  • Water your lawn daily until your lawn is fully established, this usually takes 6-8 weeks. Avoid this step if there is continuous heavy rainfall.

  • Your lawn is ready for its first mow when the blades of grass are hitting heights of 6-8cm. Don’t remove more than 20% of the grass in the first cut.

  • To keep your lawn healthy, remember to use fertiliser when required.

How To GROW Your GRASS SEED

BEST TIME TO SOW

Step 1: Prepare the SOIL

Good preparation = better germination

Clear the area THOROUGHLY. Remove weeds, rocks, and debris. THEN Loosen the soil – UsING a rake or tiller - SO THAT THE SOIL IS NOT COMPACTED.
IMPROVE soil quality by uSING A PRE SEED FERTILISER.

Step 2: SOW YOUR SEEDS

SPREAD THE SEEDs EVENLY

FOR SMALL AREAS  spread by hand. For lARGER areas WE RECOMMEND USING A SPREADER. CLICK BELOW TO CHECK out sowing rates for NEW Lawns or OVERSEEDING.

Step 3: RAKe & WATER

WATER WELL BUT LEAVE NO STANDING WATER

Gently RAKE THE SEEDS INTO THE TOP LAYER OF SOIL. LIGHTLY PRESS DOWN TO IMPROVE SEED TO SOIL CONTACT. LIGHTLY WATER THE SOIL AND BE SURE TO KEEP IT MOIST.
DO NOT LET THE SEED SIT IN STANDING WATER.

WATCH OUT FOR 👀

⏰ SEE GROWTH IN AS LITTLE AS 7 - 10 DAYS.

✂️ ONCE THE GRASS REACHes 7cm, IT IS TIME TO CUT.

💦 KEEP FREE FROM FROST & STANDING WATER.

SOME FAQ’s

How long does grass seed take to grow?

Patience, my friend! Our grass seed starts sprouting in 7-10 days, but full coverage can take a few weeks. Good things (and great lawns) take time! 🌿

When is the best time to plant grass seed?

Spring 

✅ The temperature is rising, so seeds will germinate well.

✅ Rainfall helps with moisture (but dry spells mean more watering from you!).

⚠️ Weeds are more active, so you might have to fight off some uninvited guests.

⚠️ Hot summer weather can stress young grass before it’s fully established.

Autumn

✅ The soil is still warm from summer, helping seeds germinate quickly.

Rainfall increases, meaning less watering for you!

Weeds are less aggressive, so your new grass has less competition.

✅ Roots have time to establish before winter, making for a stronger, greener lawn in spring.

Winter & Summer – Not Ideal!

Winter is too cold for germination. Seeds will just sit there, waiting for warmer days.

Summer is often too hot and dry, making it harder to keep new grass hydrated.

How often should I water newly sown grass seed?

Watering is crucial for seed germination, but balance is key—too little and the seeds dry out, too much and they might rot.

For the best results:

Water lightly once or twice a day to keep the soil consistently moist but not soaked.

Use a gentle spray or sprinkler to avoid washing away seeds.

Once the grass starts sprouting, reduce watering to once a day or every other day, depending on weather conditions.

When the grass reaches about 2 inches tall, shift to deeper, less frequent watering to encourage strong root growth.

Avoid overwatering—soggy soil can suffocate seeds and promote disease. The goal is damp, not drenched soil.

How can I make sure my grass grows?

Success starts with quality seed and proper preparation. Our seeds are DEFRA tested for high germination rates (+90%) — so growth comes down to how well you prepare the ground.

Key Steps to Get the Best Results:

Clear the Area – Remove weeds, old grass, and debris to give seeds the best chance to take root.

Loosen the Soil – Lightly rake or aerate the soil to improve drainage and seed-to-soil contact.

Apply Fertiliser – A pre-seeding fertiliser (like Grassias®) gives young grass the nutrients it needs to establish strong roots.

Sow the Seed Evenly – Spread seeds at the recommended rate, avoiding clumps or bare patches.

Press the Seed In – Lightly rake or roll the area to ensure good soil contact without burying the seeds too deep.

Water Consistently – Keep the soil moist but not waterlogged, watering lightly once or twice a day until the grass is established.

Protect from Birds & Foot Traffic – Use netting or a light covering if needed, and avoid walking on the area.

How do I make my lawn greener?

To get a greener lawn, focus on feeding, watering, and mowing correctly. Use a 6-9-6 fertiliser for balanced nutrients or iron sulphate to enhance colour and harden the grass. Apply fertiliser in spring and autumn for the best results. Water deeply but less often, preferably in the early morning or evening, to encourage strong roots and prevent evaporation.

Keep your lawn healthy by mowing at the right height, aerating compacted soil, and overseeding thin areas. If moss or weeds are an issue, iron sulphate helps suppress moss, while a selective weed killer targets unwanted plants. With regular care, your lawn will stay lush, green, and thriving.

Should I use fertiliser?

You don’t have to use fertiliser, but we highly recommend it if you want faster growth, stronger roots, and a greener lawn. Fertiliser gives your grass the essential nutrients it might not get from the soil alone, helping it establish quickly and stay healthy year-round.
