Mophead Hydrangea

Hi All, second question of the day.

This hydrangea is new this year and started of blue in color. Summer is ending and i am wondering what i need to do with the plant to get it over winter. Things like pruning, thinning out or anything else. Can't see any noticeable change in the height yet, but....... Any guidance please.imageimageimage

Photo's attached.

Cheers John.

    It's usual to leave the dead flowers on during the winter, because next year's buds will be protected from the worst of the weather.

  • Im not sure that it'll grow much there ... It hasn't got much room image

    As Welshoninon says - you can leave the heads on for protection, no need to do anything else, but Dove's right - it doesn't have a very good location.

    Is it in the ground or in a pot of some kind? Whichever it is, it won't be happy there long term I'm afraid image

  • Fair enough guys so it needs to have more room but how much is enough ??. image

  • Well, it's base circumference of stalks coming out of the ground when it's adult will be about a meter Diameter most likely. It you don't want it getting that big give it less space. Leave on The heads and don't clip them off until last frosts have finished. Cut to just above a new bud. They love plenty of water In the growing season.  Good luck

    They can get big. image

    Like many plants, they'll grow to fit  a space until they reach their optimum height, and that can depend on the conditions you give them too. At full size here they can be six feet, and the same in diameter.

    It really depends what room you have available, but a big shrub doesn't perform to it's best if it's constantly being forced into a smaller space.

  • I recall reading somewhere that "Hydrangeas" will change to suit the soil that they are planted in - so if they are in an acid soil they will eventually go pink/red and conversely if planted in an alkaline soil they will ultimately be blue. Is this true? And further, if so how long is the transformation period?

  • Good advice from all many thanks. I will look for an alternative spot. What about a large pot image ?.
