Hydrangea macrophylla (teller)

Hi,

We have bought a couple of nice strong looking Hydrangea Macrophylla from The Range of all places.

One is a White and the other a Blue and the question is are these varieties still prone to the colour change due to ph ?

Our soil is just below 7ph so the Blue should be fine ? but what about the White , would its colour be affected by a higher or lower PH ?

 

No, white will remain white Ricky
The blue though will prob turn pink or pinky blue at that ph level

 

Hi ricky 101, You can buy granules (Hydrangea Colourant) at Wyevale that you mix with water to keep the PH around 4. I feed mine with Ericaceous feed.
