Hardy hibiscus require lots of water to thrive. I would water it deeply every other day for several days and I imagine the roots will fill with water and start sending up more shoots. The sun is not an issue for it, it's the lack of water that's the problem
That one didn't make it but the hibiscus did and I have update videos on how they did. Next time I will cut more hydrangeas instead of just one. Thank you for watching ❤️
Thanks for watching! Yes same for both make sure your using a lot of perlite so your cuttings don't mold, and keep it out of direct sun. I hope that helps you
