How to overwinter this type of hydrangea
Hi,I heard I should put my hydrangea before frost and it should’ve been brown and dry by now. But mine is still flowering.
Someone also said this is different type of hydrangea.
How can I overwinter this type of hydrangea?
Regards,
Natalia

Yes, you can overwinter this type of hydrangea (which is a 'Hydrangea macrophylla') in a pot, but it can be tough.
If you wanted to keep it over the winter, it needs to be placed in a cool yet frost free place at around -0 degrees if you live in a hardiness zone of over 2, or a mild 3 if you're lucky. It also needs to be bright, so if you have an indoor patio or a covered balcony.
Once you placed it there, you should cover the pot in isolating material such as bubble wrap or jute cloth. Pot covers are also great. As the goal is to prevent the soil to freeze, and as such damage the roots, you also need to remember to check on the soil every so often to make sure it doesn't dry completely.
Otherwise, if you have the availability and live in the milder zones of up to 3, you can let it overwinter in the soil to make it easier. That way, the ground isolates the roots and prevents complete drought. You can also cover the plant with fallen leaves once it has entered its dormancy.
Hope this helps and good luck!
My hydrangea survived the winter, thanks 😀
They are in a colder room in the house. Now they start to sprout new leaves.
When is the best time to put them back outdoor? Do I need to do anything to acclimatize them?

If your plant already has new leaves it is best to keep it indoors, or in a frost-free place, until there's no more frost at night. This is usually in the second half of May, but it depends on the season and where in the country you live. If you move it back outside early you need to watch the temperatures and cover it up if it dips below 0.
Before you put them back outside you should introduce the colder temperatures gradually - a good way to do this is to have it outside during the day, and then take it back inside or cover it up at night.
While you wait for the temperatures to be high enough to move it back outside you should give it some more light and water as it has started growing, but if you can keep it in a cool place even now that would be for the best!
