Q.Rooting variegated hydrangea
I live in Los Angeles, California. I planted some cuttings in late August covering it with 2-litre plastic soda bottle. Now, new leaves are coming out and I believe the roots are strong. When do I have to remove the plastic cover? It is now fall and I am afraid they may die because of changes in temperature. I have searched the internet and could not find an answer as to when to remove the plastic cover.
Any assistance will be greatly appreciated.

It is best to remove when the roots have formed. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/hydrangea-propagation.htm
Thank you BushDoctor for sending the link. I believe my hydrangeas have rooted well as it has shown new leaves. I planted them about second week of August, technically two months ago.
