Frequently Asked Questions

When can I start using GreenThumb?

You can adopt our services at any time of the year. There is never a ‘bad time’ to start improving your lawn.

Do I have to be at home when you come and treat my lawn?

The majority of our customers are not at home when we call. Since all our vehicles and Lawn Operatives are self-sufficient, we can carry out your treatments as long as we have access to the lawns.

If you would prefer to be in when we are treating your lawn, we will do our best to accommodate your request.

I have children and /or pets. What should I be aware of?

We recommend that you keep off the lawn until any liquid part of the treatment has dried (approx. 2 hours). This stops it being walked off. And this is especially true of our NutraGreen Autumn Long Treatment, we recommend that you keep off the lawn for more than 2 hours then as it could stain a carpet or wooden floor, if it were walked into the home.

Grazing pets such as rabbits and guinea pigs should be kept off the lawn for a minimum of two weeks or three cuts, whichever occurs latest, to avoid ingestion of Ragwort, in particular, which becomes poisonous to them as it dies back.

Do I have to sign a contract?

No, we want our customers to continue with GreenThumb based on our merits in creating a healthier, greener lawn for them - not because they are stuck in a contract. Of course, with our treatment programmes, you will need to sign a Direct Debit Mandate with the relevant T&C's which relate to this payment option.

Do we need to apply Oasis when we have had so much rain or it’s raining?

Yes, Oasis is more than just a water conserver; it is a water management treatment that incorporates a very important bio-stimulant benefits which result in a stronger, greener lawn.

After rainfall ceases, soil moisture depletion can occur rapidly. However, Oasis maintains soil moisture levels near the roots for extended periods, aiding in situations of excessive dryness. This facilitates rapid soil rehydration around the roots when moisture is present again (either through watering or rainfall), promoting plant recovery. Crucially, the inclusion of a bio-stimulant ensures optimal nutrient
utilisation from the soil. Working in tandem, the water management system and bio-stimulant effectively direct nutrients to the plant, enhancing the efficiency of fertilisers, benefiting the grass throughout the season.

How to keep green grass during dry spells?

Keeping grass green in dry conditions requires more than just watering. During hot weather, lawns can quickly lose moisture through evaporation, especially in exposed areas. The key to maintaining vibrant, healthy turf is deep root hydration and efficient moisture management.

That’s where Oasis comes in. It acts as a wetting agent for lawns, improving the movement and retention of water in the soil's root zone. Unlike surface watering that quickly evaporates, Oasis ensures moisture reaches—and stays—where it matters most. This not only keeps your grass greener for longer, but also reduces the frequency and cost of watering your lawn.

Plus, Oasis includes a powerful bio-stimulant, which enhances nutrient uptake and strengthens the plant against stress. It’s a complete solution for dry lawn care and green lawn maintenance, especially during UK summers.

How much does a new lawn cost?

The cost of a new lawn can vary greatly depending on size, turf type, soil preparation, and labour. On average in the UK, laying new turf can range from £10–£20 per square metre, including installation. Larger or more complex projects may incur additional fees.

However, the real cost isn't just in the installation — it's in the long-term care and maintenance. Without proper aftercare, a new lawn can struggle to establish, particularly during dry spells. That’s why we recommend using Oasis to boost hydration and nutrient uptake from day one.

This helps your investment thrive by reducing the need for reseeding, patching, or excessive watering. By keeping moisture locked into the soil, Oasis protects your turf from drought stress, supporting healthier, stronger root development.
