Q

I grow lots of hy­drangeas of dif­fer­ent colours, and all of them live in pots. I wa­ter them only with rain­wa­ter be­cause I have heard that they dis­like it from the tap. How­ever, I have emp­tied my wa­ter butts due to the dry weather. Is there any­thing I can add to tap wa­ter to make it more ac­cept­able to them?

Rain­wa­ter is def­i­nitely the best choice for your plants in pots. It’s good for the en­vi­ron­ment to be col­lect­ing rain­wa­ter like this and it’s also the most suit­able for acidlov­ing plants which don’t like the hard­ness of tap wa­ter. How­ever, as a tem­po­rary mea­sure it’s fine to use tap wa­ter. Your blue hy­drangeas may turn pink over an ex­tended pe­riod as they lose their abil­ity to ab­sorb alu­minium from the soil, but once you re­sume rain­wa­ter, things should re­turn to nor­mal.
