I have 2 large Hydrangea in my yard that I would like to transplant and also divide. Is this possible and how can I do this without killing them. They both are meaningful to me as memory gifts for my parents. I don't want to ruing them. Thank you.

You can divide hydranges. Each division will need both roots and stems in order to grow well. So, depending upon the size of your plant and the root mass, you may be able to make several divisions from a single plant. Dig the plant, lay it on its side and slice through the plant making sure each division has roots and stems. Then replant. If, after digging the plant it doesn't appear to have sufficient rootmass or stems, you might take a different approach: layering. Here's how: after transplanting your hydrangeas, allow them to become established in their new homes. In mid-summer, bend a few of the most pliable branches down to the ground, so they lay on the ground. Slightly nick the underside of the branch and then anchor the branch down to the ground so the nicked or injured part makes good contact with the soil. Mound some soil over the branch where it touches the ground and then water the plant regularly, making sure the layered branch gets its share of moisture. By the end of the summer the layered branch should have developed roots. When this happens you can cut the branch from the plant and either pot it up or plant it elsewhere in the garden. You'll have an exact clone of the parent plant when you propagate through this method of layering.

Best wishes with your hydrangeas!
