How quickly will climbing hydrangea grow on a wall and what are ways to stimulate this growth?
Growth rate is dependent on the aspect,the soil fertility,the exposure and drainage among others.


Hydrangea petiolaris is best suited to a shady position,if you have an established plant feeding with a seaweed based liquid food will help growth.Should you be considering planting,open the soil by adding coarse gravel to improve drainage,incorporate compost into the soil and keep well watered until the plant is established.
Reply:Hydrangea petiolaris is quite a slow grower and will probably outlive you. It thrives any soil. An application of fertilizer and an occasional mulch will keep it healthy but won't make it grow any faster.


The good news is that it requires little pruning ----just remove the dead heads off the flowers ----- and attracts birds which like to nest in the thick branches.


Good choice.
Reply:The clue is in the word Hydrangea. They like plenty of water (hydra). Mine has started flowering today in the Midlands. I don't think you will need to encourage it much, they are quite prolific.
