I think I've cut my hydrangea plants too short?

I got carried away with the nice weather and a pair of secateurs last week.My plants are about 4 inches tall. Have I ruined them? Will they be back to normal in the summer? Thank you.

Yes they will grow just back fine, but they may not flower this year.
Reply:They should survive but you may not get many flowers. Next year control your secateurs until after the last frost. The dead flower heads are supposed to be left on the bush until after the last frost to protect the new shoots.
Reply:you'll have lots of green this year oh but look out next year people will want to know your secret
Reply:Oh dear! They should grow again come spring. Perhaps you could feed them to show how truly sorry you are that you cut their heads off?
Reply:I think they are very resilient. As long as there are leaf nodes showing they should grow OK. I doubt if they will reach their former glory this summer, but next year they should be fine.
Reply:You've almost certainly cut off the flowers for this year.Hydrangeas should have the dead flower heads removed down to the first prominent pair of buds,not as low as four inches.

Console yourself with the thought that you'll get strong regrowth and next time leave the dead flower heads to protect the new buds overwinter.
Reply:Even if the plants don't blossom this year, you can take heart because they should be bushier next year and you should get a bumper crop of blossoms.
Reply:Ooooooooops! lol. Dont worry now, have to see what happens. If it makes you feel better, I think my roses are too short.
