Care of potted Hydrangea....

summiebee(44601)June 1, 2006

I am planning on potting a red forever and ever hydrangea in a clay pot. When late fall/winter comes. Do I just bring it into the unheated garage like I would a rose tree? I want to make sure this is doable before I "do" it. I really like the way they look in a traditional clay pot and thought this may be a good idea to keep from having to plant this large clay pot with flowers each year.

I guess I should also ask if this is the best one to pot for the most blooms for the longest time?

Plants in pots usually have to be 1-2 zone down from your zone to survive well outside. Make sure place you put it in winter is very well protected.

From Dan at Heronswood...'for those in less benign climates wishing to containerize hydrangea - plant a 1 gal hydrangea directly into a 15 - 25 gal container of bark based soilless medium. Fertilize and water as for those planted in the ground, replace potting medium every three years or as needed. Move to garage, unheated porch, greenhouse for winter, protecting only during the coldest months. '

THanks for the info. I will have to try this and see how it works out. :) I have the proper sized container and soil. SO I will go buy one tomorrow and put it in my garage nov-april. :)

Few more tips,
-don't forget to water it sometimes during the winter as you probably do with a tree roses. What I usually do, when we got a fresh snow (not so often), I throw one-two showels of it at the base of the plant and let it melt naturally.
-though you could bring hydrangea out of garage earlier than roses, late winter/early spring freezes could kill swelling flowering buds and all your troubles will be for nothing.
On another side, in dark garage new growth will be yellowish, weak and succeptible to powdery mildew or leaf spot.
Therefore, if you put your large 15-25G pot on a some kind of cart and will be able to carry it in and out of garage starting from March you'll do good to the plant and make your hauling much more effortless. 25G pot with mature hydrangea could weight around 100lbs.

I'm in a warmer end of z6 and hydrangeas in ground blooms for me in 4 years out of 5, but I need it in a one place where it can't be planted, so I'm doing pot overwintering and it works perfectly.
