hydrangea
Hydrangeas like this mophead variety can be a real delight and source of color in your garden, if you know how to care for them.

If you’re like me, you remember seeing hydrangeas growing in your grandmother’s yard. The shrubs were popular in cottage gardens and were often planted around porches, especially where I live, in the South. They still have an old-fashioned feel, but there are some gorgeous new varieties available nowadays, and let me tell you: these are not your grandmother’s hydrangeas.

I mean that in the best possible way. Some of the older hydrangeas were very picky about being pruned. If you cut them back at the wrong time of year, you wouldn’t get any flowers the following year, because they produced buds on what’s called “old wood.”

Even if you kept your pruning shears in the garden shed, a late cold snap could take out the buds. If the weather did cooperate, you still had only one flush of flowers in May or June. Hydrangeas were summertime showstoppers, but you had to wait a whole year for an encore.

Many of today’s hydrangeas have been developed to fix those flaws. ‘Tuff Stuff’ available at Monrovia is a new lacecap that re-blooms vigorously, producing pinkish-red flowers from midsummer until frost. It can take part shade to full sun, as long as it has adequate water, and it’s hardy in zones 5 to 9. (Don’t panic if your ‘Tuff Stuff’ has blue blossoms. It just means your soil is acidic.)

‘Blushing Bride’, introduced in 2005, is a re-blommer from the Endless Summer series. It’s a mophead, sometimes called a bigleaf or French hydrangea. Technically, it’s Hydrangea macrophylla, with the big, blowzy flower heads Grandmomma grew. ‘Blushing Bride’s’ flowers start out snowy-white and blush pink as they age. You don’t have to prune, unless you want to control its size. If you do prune, you don’t have to worry; flower buds grow on old or new wood.

Learn how to grow and use the bold and beautiful hydrangea.

‘Forever and Ever Peppermint’ from Forever and Ever Plants may not really bloom that long, but it does have a long flowering period, from spring into fall, and bears on new and old wood, so again.  It’s a mophead with white petals striped in peppermint pink (or bright blue, in acid soils). While the flowers are large, the plants only reach 2-3’ in width and height, so this is a good choice for a container.

When you’re shopping for hydrangeas this year, read the tags to make sure you’re getting an easy-care, ever-bloomer. Grandma would’ve loved these!

Types of Hydrangeas:

  • Mophead hydrangeas, or Hydrangea macrophyllas, have rounded, globe-like flower heads. Most prefer morning sun and afternoon shade, but avoid heavy shade, which can cause poor flowering. Generally speaking, the further north you live, the more sun mopheads can tolerate. Mops come in blue and pink, as well as white, lavender, and lilac
  • Lacecaps have flattened, loosely arranged flower heads. Also known as H. macrophylla normalis, they have the same basic growing requirements as mopheads.
  • H. serratas are a subspecies of the macrophyllas, and they’re smaller shrubs. Give them part shade, if you live in a sunny climate; elsewhere, they can take more sun.
  • H. arborescens is sometimes called smooth or wild hydrangea. The best-known variety is ‘Annabelle’, which bears big, white blooms and flowers dependably. Give this one some shade, especially if you live where the summers are hot.
  • H. quercifolia, or oakleaf hydrangea, has cone-shaped flower heads. It’s native to the southeastern U.S. and often droops when the sun bears down, but be careful not to overwater. It needs good drainage. Oakleafs can be huge, so look for a dwarf if space is limited. If planted in a sunny spot, it will develop gorgeous fall leaf color. Give it some shade if your climate is hot.

How to Care for Hydrangeas:

  • For lots of beautiful flowers, choose a hydrangea that’s cold hardy in your garden zone (See our Plant Finder). Check the plant tag to see if it requires sun or shade, so you can plant it in the right spot. Early summer and fall are the best times to plant.
  • Put your hydrangea where you won’t have to prune it. These shrubs grow vigorously, and besides—they’re big and beautiful by nature.
  • Plant in soil that drains easily, and add good organic material, if needed, to help loosen it.
  • Don’t plant your hydrangea any deeper than it was growing in the pot.
  • Avoid planting under trees, where the roots will compete for moisture and nutrients.
  • Keep your hydrangea watered for the first couple of years, to help develop strong roots. But don’t let water stand around your plants. Oakleafs are especially prone to root rot when they are kept too wet.
  • Fertilize once a year with a balanced, slow-release fertilizer, or fertilize twice a year with 10-10-10. Commercial manure or compost is an organic alternative. Stop fertilizing by August to let your hydrangea get ready to go dormant.

    Deanna, look at the plant tags on hydrangeas sold in your area to make sure they're recommended for zone 8. Then make sure to plant yours in a shady spot and water often. good luck.

    Sherri, some of the hydrangea macrophylla cultivars are labeled to grow in zone 10. i'd try to find some plants i liked, and look them up online for specific growing information. or see if you have a neighbor growing one in his or her yard, and ask about it. i've found that gardeners love to share what they know, and here's hoping you'll find someone who can tell you what works in your area.

    I have always been amazed at how different soils can change the color of your hydrangea. I know where I live, I have the blue hydrangeas and I love seeing them in full blooms that I can cut off and use for table arrangements. http://www.onlineplantnursery.com

    Amy, I've even got a spot in my yard where my blue hydrangeas have turned almost purple--they're a really pretty color! It's amazing how the difference in the soil changes them!

    HI, Bonnie. If your hydrangea leaves are getting black spots, it's probably a fungus. I'd take them off and throw them away--don't compost them, where disease could spread. But if it's ALL over the leaves, avoid removing too many, so the plant doesn't die. You might want to take a couple of leaves to the garden center and ask someone to identify the problem and recommend a spray. As far as trimming the dead blooms, it depends on what kind of hydrangea you have. If you cut off the dead stuff too late in the season, you'll be cutting away the wood where the new blooms would appear next year. The best rule of thumb is to prune off any dead flowers immediately after they bloom, to avoid that happening. Good luck.

    I have large hydrangea bush that blooms amazingly, the only problem I am strarting to have is that it is tipping over. Should I trim back in the fall and how much should I trim or cut it down to the bottom as we do with many perranials in the fall and they come back every spring. It gets plenty of sun and the blooms are big and gorgeous. I also do remove the dead flowers after they bloom.

    I bought a hydrangea at the store. It has been on my table since but not doing well now in the last week. It is watered but I am wondering if it is lacking root space in the little pot. I want to plant it outside but I am still worried about the cold killing it here in Nj. What do you suggest I do?
