Hydrangea in zone 5a

20 Jan 2012
Cloudy -5°C / 23°F

Spent yesterday trimming houseplants. Having trouble with hydrangea. I wanted to let it grow over the winter but it has other ideas. So I trimmed it up and moved it to up stairs where is about 62-66 degrees. Hopefully moving it from the living room will make an improvement. Right now it has 2 leaves that are brown. I do see a bud on one branch. Anything else I should do for it?



I have several young hydrangea plants that I am overwintering in the greenhouse. The greenhouse has a minimum temperature of 5C (41F), and so far most are still in full leaf, but one or two of the very young plants have lost most or all of their leaves. However the plants are not growing, which is just as well for with the low light levels, even in the greenhouse, any growth would probable be weak and spindly, and eventually have to be cut out.

I would prefer that all the plants lose their leaves and so have a proper winter rest, also keeping their leaves makes them more prone to insect infestation, but other plants in the greenhouse require the temperature that is set.

So my advice is to let the plant rest: keep it as cool as possible – cooler than you have at the moment, do not let it dry out but don’t saturate the soil. When the time is right it will start to grow again of its own accord, then it will want plenty of light and obviously more water.

Avoid cutting back any stems on your plant, the leading buds on last years stems will carry this years flowers,(while this applies to the majority of hydrangeas, there are a few exceptions)

Why do you keep it inside? Just want it as a houseplant? I always leave mine outside over winter. It is behind decorative bricks shielded by the brick porch and house, so it is protected from wind, but no matter how cold or how much snow we get, it comes back even better the next year. Just curious as I love Hydranges’s and if they were easy as houseplants, might consider doing some inside.

I brought it in since I have had 2 die on me. This one really had no growth this past summer and I figured it was weakening. My soil is like clay. Gets hard as concrete during the dry spells. Just thought I’d try to save it. I have moved it to my second storey hall. south facing. temp range 60-66. It is the coolest part of the house. Thanks for all your help. It is appreciated. Karen
