What products would you recommend to fill large, deep cracks in a lawn? And we have a pet rabbit, so we need grass that rabbits like. 

• To fill the cracks, spread Tui Lawn Preparation mix over the surface and water it well to fill the gaps.
• This process may need repeating a couple of times to blend the mix into the existing lawn soil.
• Next, sow your chosen Tui Superstrike Lawn Seed over the bare patches and water it in. Avoid walking on the area or placing the rabbits on the grass until it is well established.
• Rabbits eat most types of grass, so plant varieties that suit your region and property.
• It might be worth addressing why the cracks are there which will be due to a lack of water. Try and water the lawn at least once or twice a week, the cracks will close up over time, but the addition of Tui Lawn Preparation mix will help improve the soil structure.
