\u201cIt’s in a sheltered morning sun, afternoon shade position. Thank you for any tips that I may have overlooked.\u201d<\/p>\n
In order for hydrangeas to turn a shade of blue, it all boils down to the pH of the soil.<\/p>\n
The colour of a hydrangea flower depends on the chemical makeup of the soil it is planted in. If the soil has a low pH, the hydrangea flower will be blue. If the soil has either a high pH, the hydrangea flower colour will be pink.<\/p>\n
Lowering the pH of the soil to make it more acidic can be done by adding organic matter and one item gardening enthusiasts recommended was to use tea bags.<\/p>\n
Martin Leachford commented: \u201cI\u2019ve heard putting tea bags around the base helps if you want to turn pink hydrangeas blue.\u201d<\/p>\n

I turn them a gorgeous shade of blue every year by putting used tea bags in the soil around them.\u201d<\/p>\n Marie Dean wrote: “My dad said that tea bags are fantastic for this. He would put them in the hole before planting to turn them blue, it always worked.\u201d<\/p>\n Carole Griffin instructed: \u201cPut used broken tea bags around the roots, it will turn a stunning blue colour in no time. Mine turned blue, but preferred the pink so took the tea bags away the blooms went back to pink eventually.\u201d<\/p>\n Tea bags are a staple in most British households. For those looking for the cheapest ones, they can be picked up in Asda for 34p, at Sainsbury\u2019s for 70p and 79p at Morrisons.<\/p>\n Other group members suggested adding nails to the soil to turn hydrangea flowers blue. Marion Chapman said: \u201cThe age-old tale if you want them blue put a load of old iron nails in the soil under where the roots will go.\u201d<\/p>\n Kay Ruffle wrote: \u201cBury old rusty iron debris near the roots, it turns the blooms blue.\u201d Bee Mcginn commented: Rusty nails turned my blue years ago. But now I prefer pink.\u201d<\/p>\n Debbie Grice claimed: \u201cMy mum used to put rusty nails in water and leave them for a couple of weeks and then put the brown water in the watering can. Stayed blue all the time.\u201d<\/p>\n However, one gardener highlighted that there are only some types of hydrangeas that have their colour altered.<\/p>\n Gilbert Collins said: \u201cNot all hydrangea blooms change colour. It depends on the variety of hydrangea.\u00a0 I have a steel stem one that is purple and all my lace caps changed to bright pink.\u201d<\/p>\n The main types of hydrangeas that can have their colour changed are hydrangea macrophylla\u00a0or\u00a0hydrangea serrata.<\/p>\n
