How do I apply Saturaid to a dry, patchy lawn and will it help with watering? 

• Saturaid breaks up the surface tension in soil and so water can penetrate down to the roots where it is needed most and will help with water retention.
• Break up the soil crust in areas where there are dry patches using a rake before applying.
• Top dress your lawn with Saturaid, spread evenly over the soil.
• Use at a rate of 50g per square metre (or 4 heaped dessertspoons), water it in well after application.
• Saturaid goes soapy to start with, that is the surfactant that is in Saturaid working dispersing water. 
• The pack instructions say to apply every 6 months, you can re-apply every three months, or as required. 
• The bare patches will need oversowing with lawn seed in spring or in autumn.
