How to Plant and Care for Hydrangea Bushes

Nearly all mopheads considered to have the ability to change bloom color. The color is determined by aluminum availability, which in turn is based on the soil pH. When the soil/substrate pH is acidic (4.5 – 5.5), the color can be expected to be blue because aluminum is generally highly available in a low pH. When the soil/substrate pH ranges from 5.5 to 6.5, flowers may be pink, blue or lavender, or a mixture of pink and blue flowers may be present on the same plant. The flower color is not permanent. The color will ultimately be dependent on the soil pH of the landscape into which they are eventually planted.
I live in Orlando, Florida (zone 9) and am wondering if white snowball hydrangeas from my father's home in Delaware will grow and thrive if I transplant them. They have bloomed prolifically for the past 40 years or more. Last fall they were cut back to the ground, but new little ones are coming up now (June). I am visiting, and would to take some back to Orlando with me.
Hi, Michelle. If the hydrangea is an ‘Annabelle’ snowball, then there is a good chance it will survive in zone 9.
When we bought our house there was a very large, old hydrangea in the front flower bed. The rhizomes spread terribly and had overtaken the garden as well as growing underneath our sun porch. We decided to pull the plant out last summer and start over. I was recently gifted with a Hydrangea Mycrophylla. Will this variety do the same thing?
Nothing was said about when or if you can move a adult plant, I am moving my flower bed this year and I have been wondering when its safe to move my Hydrangea. Its about 4 years old. Do you have the answer for me?
Transplanting is best done when the plant is dormant, so either in the early spring or in the fall. If you live in an area with harsh winters, spring is best.
Transplanting can also be done in the summer, but you will need to provide the plant with plenty of water and it is almost guaranteed to wilt, but should recover with time.
What zone is 39470 in
You are in Zone 8b. See the USDA Plant Hardiness Zones map here: https://planthardiness.ars.usda.gov/PHZMWeb/
I live in So California, do these plants die off for the winter? I planted 3 plants and 1 seems to have died off. The other 2 still have some leaves but are looking bad.
We live in Manhattan Beach and planted three 5 gallon hydrangeas years ago in partial sun. First problems showed up in a little time with wilted and stunted leaves/stems - looking really bad. I didn't know that hydrangeas (and azaleas and gardenias and fuchsias and others) do best in acidic soil - which is NOT Manhattan Beach. So I dug a large 6"-8" wide ditch around the hydrangeas to the bottom (and lower) of the root ball, and add an acid enhanced planting mix (that I can't find anymore, btw). That helped, and repeated monthly feeding with Miracid also helped. But the biggest gain was when I pruned back the stems severely last fall - now they are lusciously growing. I keep feeding Miracid monthly.
