This is a guideline only, if in doubt contact the manufacturer or start on a lower setting to be safe. Many thanks A1Lawn **Q: For pre seeding in november (now) should i use this or the other 'a1 pre seed'? thanks** A: I believe this is for use on established turf only. My turf (not seed) was laid at the end of February. I was recommended to use an autumn feed around October. I chose this product as it seemed straightforward and easy to use. I have not been disappointed in the results. **Q: When can you use on newly seeded lawns?** A: We would suggest using it from around 4 weeks post germination. **Q: is this product child and animal recommended ?** A: Hello, This product is safe for pets and children one the granules are fully dissolved. Normally this will occur around 48hours after application with plenty of rainfall/water in that time.
