Product Questions
Product Questions
I have just stumbled on this product and cannot wait to use it. I have just bought a cottage in Midhurst West Sussex and I have never ever had a garden like it. It is saturated sodden in the winter and like concrete in the summer. I have left a beautiful well stocked garden and landed with a garden with not a plant in site....and boggy grassy patchy lawn to boot.
I have only ever had a sandy garden before having always lived near a beach.
I have aerated the grass to an inch of it's life and can't wait to get going.
My question is, it is now coming into February. When is the absolute earliest I can start to re seed the baldy patches.
Thanks so much
Sue
Thank you for your enquiry. The grass sowing season is generally from March - September. You can confidently sow grass seed when temperatures are 8-10 degrees and above consistently for at least two weeks with no adverse weather conditions forecast. Always consult a two week forecast prior to sowing.
You may also want to consider our QUICK RELEASE: Pre-Seed fertiliser. It provides the soil and seed with all the nutrients they need. It helps to create a great foundation for sowing new seed whilst strengthening existing grass. It will also help increase germination and establishing a strong root system.
Congrats on the new house and we would love to see some before and after pictures of the garden.

I’m looking to over-seed a mixed/clay soil with few areas that are prone to moss and want grass that has fine grass blades - is this the right product?
Thank you for your recent enquiry.
IMPRESS: Clay Master Lawn Seed is a mix of fine fescue and perennial ryegrass along with a small amount of stalked meadow grass. Whilst it does consist of fescues which is a finer grass variety the ryegrass is slightly thicker, which is known for its durability and hardwearing properties. There are finer mixes available but this does grow extremely well in clay based soils. The tall fescue component has a strong deep rooting system which not only allows it to penetrate your clay soils effectively but ensures a drought tolerant lawn, especially in clay soils that are prone to dryness. It does have some shade tolerance due to the meadow grass in the mix. https://thegrasspeople.com/impress-clay-master-lawn-seed
If you have any other questions I would be happy to help
Many Thanks

I would like to apply a fast release fertiliser to help it grow.
Can I apply fertiliser now or is there a recommended grass height/time period after sowing ?
Thanks for your question. I wouldn't recommend applying fertiliser at this stage to help speed up growth - instead, you can apply a fertiliser after the lawn has had its first mow. The recommended height is 5-7cm and the lawn should be at the 6-8 week post sowing mark. If you want a quick release, I'd opt for our QUICK RELEASE: Spring / Summer fertiliser, or alternatively you could try our liquid feeds - Make it Grow or Make it Green will work well here and give you a luscious lawn for summer!
Many Thanks

How often should I water my new lawn: https://thegrasspeople.com/often-water-lawn/
The seeds are completely natural and not coated with anything – so aren’t bird repellent. We have a few recommendations on our blog on this but in short:
1. Use visual deterrents such as reflective objects
2. Use noise deterrents such as windchimes
3. Place netting over the area
4. Provide alternative food source such as bird food
Many Thanks
