Frequently asked questions
Where does this weather forecast come from?
Forecast data is from Open-Meteo for the CR4 3FH postcode (South London) and refreshes every 30 minutes. The gardening guidance on top of it is produced by the Grass Barbers grounds team based on the season and conditions.
How far ahead can I see?
Up to 16 days — the maximum horizon the free weather model publishes. The first 7 days are the most reliable, so the daily mowing and watering advice leans on those.
Can I rely on this to plan mowing or planting?
It is a practical guide, not a guarantee. Use the mow, water and protect tags as a steer, and always check the sky on the day — especially for frost, wind and heavy rain.
Do you offer grounds maintenance in this area?
Yes — Grass Barbers covers Mitcham, Morden, Croydon, Sutton and the surrounding London and Surrey areas with scheduled grounds maintenance, lawn care and seasonal site care.
