Hydrangers

I gave my hydranger plants a good handful of lime - went on holiday for 10 days and got home to HUGE flowerheads some measuring 22cm I am thrilled as they were tiny when planted 3 years ago

mine are looking so stunning at the moment I planted out 6 more along the front of my deck. A small growing one called raspberry crush. Well I liked the flowers when i 1st saw them - a nice deep raspberry colour, but I must have acid soil because they have gone a deep rich purple, beautiful!

Hydrangea.
Lime will alter the colour.

some are from cuttings so I hope I get the time right to take more cuttings (they don't always take for me)!

Lime is just to keep the colours, reds and pink etc. you need the other stuff for Blue, I forget the name. If they are in the right place they are so lovely. ????

Take cuttings in autumn-they strike easily for me then.I cut the stem with two lots of buds,and the lower buds are covered by the potting mix.
To make them blue,add Alum to the watering can.Plant shops sell it plus hydrangea fertiliser-all in one if I remember right.

My mother puts rusty metal pieces around hers . Lime for pink . alum as above for blue .
Not sure what you do for white ones . Anyone know please ?
I have a lovely white one out flowering . plus the popcorn flowered one and a double about to flower . very special .

I sometimes just take cuttings and place in vase of water . leave in our ensuite where light is good but no direct sun . They soon develop roots .
I sentimentally took many from one plant in the section about to be bulldozed in front of our townhouse . I like that we have the original now growing. actually about 5 of them out the back .

I love hydrangeas.My garden is mostly in shade,so I have hydrangeas under the trees and they look lovely with ferns.I also have fuschias in tubs and stone paths.

The newer white varieties have been bred so they keep their white colour no matter what your soil pH. Some of the older whites would get a tinge of pink or blue to them.

Yep.
I have some pink ones on the south side of my house . pink against brick doesn't do it for me, so about 4 years ago, I gave them a dose of acidy type feritiliser & this year they have turned a sort of light mauve-ish/blue colour.
I'll do it again

A guy I know grows them commercially. He has some stunning examples

My white has a tinge of green. Delightful.
