Can cuttings from hydrandea tree be rooted if left in vase of water long enough?

Question

I’ve had some in water since late summer, but they show no signs of rooting. I change the water regularly in hopes that I’ll be able to plant them in the spring.

Answer 1

It's possible to root them in water, but my research shows it usually fails. If the cuttings still look alive, try recutting the bottom of the stem, dip in rooting hormone and insert in moist potting soil.
