Review: Quality at reasonable price. - The best plant fertiliser I’ve ever had. Difference to outdoor potted plants noticeable in 24 hours. Can be heavily diluted with water but still shows results. Good container which when squeezed measures out required amount in a built-in cup at the top. Price very reasonable and will purchase again.
Review: Love it. - This is the best purchase I’ve ever made. The quality of the feed is very good, and you only need a small amount for the five litre can. My flowers are looking happier and stronger now. It’s a great value for money, and I’ve been using it for a month now, and there’s still plenty left. The smell is fine, but that’s not the most important thing to me. I love the size and design of the bottle, and how they made it is incredible.

## 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
