## Questions & Answers

**Q: How often do you need to apply it?**
A: I use once a week

**Q: How much to add to a lawn?**
A: Seller- please can you clarify. The dilution rate of 10ml per 5L is included on the bottle, but then it doesn’t state how many (e.g. watering cans) to then put on the lawn per  square metre. Without this information the dilution rate doesn’t really provide any guidance for application.

**Q: Can I use this on a recently (2 weeks) planted bay and rosemary?  They are quite young. Thanks.**
A: According to Envii, they recommend that gardeners only start treating cropping/flowering plants when they have an average of 3 leaves. Treating seedlings when they’re too young can possibly cause damage. Even when diluted, due to over fertilisation. Young plants will only have one root. However, when a plant is showing 3 leaves this indicates it has established root growth allowing them to take on additional nutrients. Hope this helps.

**Q: Is it available in 5ltr containers**
A: Yes on Amazon and the Bio8 website

Good product helps the grass to grow. All I would say it don’t use too much as it can cause ph imbalance in your soil, leading your lawn to go yellow
