How to Grow Blue Hydrangeas [And Keep Them Blue]

Acidic soil and compost will gradually turn more neutral over time, so the hydrangea flowers will slowly return to pink or red unless you keep topping them up with aluminium sulphate. Hydrangeas will only produce blue flowers in acidic soil, and if your hydrangea is blue and you haven’t made any changes to the soil, it’s most likely because the soil is naturally acidic.Keep your four-legged friend cosy and comfortable this season with our range of Dog Beds.
