GreenThumb Oasis Water Conserver

There’s a lot of science that's gone into Oasis, as there is with all our Lawn Treatments. Oasis is our solution to helping your soil make the very best use of any available moisture, whether it’s rain, recycled water or even morning dew. Oasis makes your lovely lawn flourish, keeping your grass greener for longer. We’ve now added a liquid seaweed extract to our Oasis Treatment, helping you see the visual impact of improved colour and quality on your lawn almost immediately. This innovative solution also improves your grasses root development and strengthens it against natural stress factors. 

This specialised water conserver treatment is applied as a liquid spray all over your lawn. Oasis compliments your regular watering regime, keeping your grass hydrated and healthy, but means you’ll need to water up to 80% less of the time.

Oasis - Water Conserver for lawn by GreenThumb


  • Improves absorption of any water received
  • Encourages root development, essential for healthy grass
  • Makes vital nutrients more readily available
  • Protects against the effects of dry conditions and sparse rainfall

Oasis’ triple action formula works like this:

  • Penetration: Significantly improves the movement of any moisture through the soil to the root zone where it’s required, rather than draining right through or sitting on top.
  • Spreadability: Effectively spreads water to the right places, this is essential for the roots to access nutrients due to water moving through the soil.
  • Retention: Retains water at the root zone for longer, making it more readily available for the grass plant.

Oasis can be applied from April - September, so all of our customers will benefit from this fantastic water conserver. If you’re on our Ultimate Programme, you’ll receive an extra application of Oasis with a separate visit (this extra Oasis is available separately to our customers on our Standard and Basic Programmes too - as a bolt on).
