Truncated potted hydrangea worry re care/planting

Hi,
Gardening ignorant.

Got present of hydrangea in pot and cut back (see pic). 9 inch high pot.

Can anybody tell me what this stage is called?

When I should plant it (I have info on planting details etc), and if not til spring (Mar, April?) then where to keep ie temp, light etc.

Should I expect it to flower this Summer?

Thanks

Pete

 

Thanks, John. I am obliged to you.
I will keep it indoors until I am certain (in these strange days?) that it will not be going in while frost is about. April it is then or late March. I am in UK.

Thanks again for that, John.
I will do these things

Cheers
Pete

 

While they are dormant like this, they need soil that is moist but do not let it get dry. I can usually water them about every two weeks inside my garage when potted. When to plant: once all danger of frost has passed, you can plant it outside or grow it in a pot outside. You may be able to find local/city frost date information online (it varies by city/location). The amount of sun exposure that the plant's foliage can withstand will depend on the particular species. For example, Big Leaf Hydrangea, Smooth Hydrangea and Mountain Hydrangea prefer sun until 11am during the hot summer months but Panicle Hydrangeas can take full sun. At times, I have had some of these species potted in full sun during winter (when leafless) and until early-to-mid spring (with leaves) but, once temperatures warm up and typically reach or exceed 29C or so, I move the pot to get morning sun only for all except panicle hydrangeas. Smooth and Panicle Hydrangeas develop dormant flower buds just prior to blooming in late spring (Smooth) or summer (Panicle). Smooth Hydrangea starts developing the flower buds after leaf out time while Panicle Hydrangeas typically wait closer to the summer months. The other hydrangea species typically develop dormant flower buds in late summer and open them in the spring. If this specimen is a Smooth and Panicle Hydrangea, I would expect it to develop new growth (stems) in spring 2023 to bloom in late spring/summer 2023. I would not expect the other species to normally bloom in 2023 unless this is a Big Leaf Hydrangea cultivar that blooms on both old and new wood. In that case, the new spring 2023 growth (stems) will produce blooms in late summer 2023 once the stems get old enough and tall enough to trigger flower buds production and immediate blooming.
