  • Not at all.  Most Soil Dynamics customers are up and running with ease. It's just like forming a habit, except it's in your garden and with our Free online gardening course you can see exactly how we do it at home. 

    Plus, of course, any hurdles you come across, just reach out to us as we truly want you to succeed.

  • Jurassic Juice is your solution for existing gardens. Apply weekly at the higher rate of 50-100ml per 9lt watering can for 6 weeks, then drop back to monthly. For a permanent fix in new garden beds, use Coastal Cure. It’s dug in at planting and permanently converts sandy soil so it holds moisture naturally, letting you truly build your soil from the ground up.

  • Jurassic Juice helps open tight, compacted clay soils, allowing water, air, and nutrients to move freely. This improves soil structure, supports healthier root growth, and helps your fertiliser work more effectively.

    Follow the same Initial Treatment and Intensive 6-Week Program as the Hydrophobic Soil Solution above, then continue with regular maintenance applications.

    Continue rotating other liquid products alongside the Jurassic Juice throughout this program — you can mix our products throughout this time, so add Jurassic Juice in with all your other liquids for ease.
