I've bought a hydrangea plant (macrophylla blue) and plan to keep it in a container. At the weekend I plan to put it into a larger pot than the one I bought it in, and intended to just use multi purpose compost. However, googling info about hydrangeas, it seems to be suggested that you need acid soil to keep blue hydrangeas blue - so do I need to use ericaceous compost? It says nothing on the instructions with it about acid soil, but I do want the flowers to stay blue!

Yes you defo need ericacious compost, it might (depending on the variety) survive in normal stuff but pretty much all of them prefer acid soil (they grow really well around here) it won't flower blue. Most soil in the NW tends to be acidic, if you have room you might be better putting it direct into a border.
Some of us live in the past, always talking about back then. Some of us live in the future, always planning what we are going to do. And, then there are those, who neither look behind or ahead, but just enjoy the moment of right now.
Which one are you and is it how you want to be? -
No border at all, let alone room in one! I am strictly a container gardener, having no actual garden. I will get some ericacious compost at the weekend then. Glad I found out about that before I repotted it.Originally posted by Alison View PostComment

They do look nice in pots but make sure you water with rain water not tap water to keep up the acidity - you can also buy special ericacious plant food which helps.
