Making Hydrangea Flowers Turn Blue: Lowering the pH

Certain plants need a low pH, or acidic soil to grow and thrive. The hydrangea will do well in any pH – acidic or alkaline – but the soil type will effect the flower color. If you don’t care what color your flowers are, then you will accept the fact that your alkaline soil will give you pink blooms, but many people want hydrangeas for their bright blue color.
The pH scale goes from 0-14, with 7 being neither acidic nor alkaline – it is neutral. If your soil is naturally alkaline, or has a pH above 7, you can try adding an organic amendment to bring down the pH which may change your hydrangea flowers to blue.

I live in an area that has acidic soil naturally.  We can easily grow acid soil loving blueberries, rhododendrons, azaleas and other plants – including blue hydrangeas – without adding any amendments.   I have never used any products to create an acidic soil, but I’ve read about it and this is what I’ve learned.
If you buy a blue hydrangea and want it to grow blue flowers in your yard, check your soil’s pH – in the place you plan to plant them.  Any soil that is high in lime can cause pink blooms, and that means plants near the cement walls of a house could be growing in a more alkaline soil.

There are various ways to bring the pH down to the right levels.   Making an acidic soil mix for a pot is relatively easy, but changing the pH out in an area of your yard is much more difficult, and it will need constant monitoring.  It is not a permanent fix and could take weeks to achieve.
In general, organic type matter will help lower a pH. When starting a garden add organic compost, composted manure, and / or pine needles which all help lower the pH.  Also, you may want to buy a bag of garden sulfur and follow the directions for application on the bag.

If your soil is naturally alkaline, you will be fighting the elements to get those blue flowers.  It may work better to grow them in a pot, or learn to love hydrangeas that are pink.

Early Spring In My New England Garden

Here are some pictures of what is growing in my New England garden this time of year. April is early Spring and planting anything outdoors that is susceptible to frost, in this area, is not advised until at least late May. These are the perennials that are blooming or just beginning to grow.

Did you know that chives will come back each year?  I’ve already used some in my cooking, and the clump is looking good already.  I need to get parsley soon.  That has become one of my favorites for the garden, and it can take the cold.

The peonies and bleeding hearts are sending up shoots and the hostas are just pushing through the ground.  The Coral Bells kept many of it’s leaves and new ones are growing from the center.
Not much is happening with my hydrangeas yet, but the macrophyllas seem to be starting with leaves and growth more so than the paniculatas.
I had wanted this to be a slide show, but as usual, I can’t figure out how to make that happen. It seems that even though I use WordPress for most all my blogs, each theme works differently and I can’t see a slide show option for this one.
So enjoy the big photos instead.

Spring Surprise – A New Little Hydrangea Plant!

As I uncovered the leaves from the base of the Blushing Bride hydrangea, I found that a couple of the branches had formed roots which will be new plants!  This form of ‘root layering’ or ‘ground layering’ is a great way to start a new shrub from an established one.

It’s bare and spindly looking stems are curving out from the center and then upward and at least two of them were touching the ground enough to form roots. Now, new growth is showing beyond the roots which means I will have a couple of new little baby hydrangea plants!
I have propagated hydrangeas this way before, back when I lived in my rental house. I had found a rooted stem with big leaves and a flower that was growing separate from the main bush, so I dug it up and planted it near the front steps. You can read about how I did it on my Propagating Hydrangeas page about root layering.
So for now I will let the babies grow – attached to the main plant – until they get larger. I’ll probably dig them up in the Fall and find them a place to grow on their own.  I love to find free ways to landscape.  Isn’t that exciting?

The First Flowers of Spring: Helloborus “Emma” Picture

Spring Promise “Emma”

I have never grown a helleborus in my yard until this year. I bought two of this type of perennial last fall and put them out front.   I was looking for plants that like shade and these were in the shade lovers section at the nursery.

It’s late April as I write this and both the Lenton Rose and Spring Promise (pictured) have numerous flowers. The blooms tend to droop and face downward but the leaves stayed on all winter long! I did have to trim a few of the dead leaves to clean it up, but they do seem to be very hardy.

This one called “Emma” has such pretty flowers and the other one I planted has more greenish blooms. I’m glad I have added these to my landscape. It’s nice to go outside so early in the season up here in New England and see flowers! Not even my tulips have bloomed yet.

Deadheading Old Hydrangea Blooms: What Time of Year is Best?

Last summer was the first time I planted my own hydrangea shrubs in the yard. I planted six shrubs which were a combination of the macrophylla and paniculata variety and had flowers that were blue, white, pink and somewhat green by summer’s end.
Because hydrangeas last so long on the bush, I just let them continue to change and fade and eventually dry out on their stems. I left them alone over the winter and some of the dried heads fell off, but some stayed attached until this spring.
So when is the best time to remove the flower heads? Unlike some other perennial and annul plants, the hydrangea does not need dead-heading to flourish. The dried flowers look just fine and even add some interest against the winter snow.
But, I have decided to remove the dead flowers next Fall. My shrubs are all quite small and the snow on the flowers tended to pull the stems down and bury the stalks under all that snow. With just the stems left on the shrub, the snow should not be able to do as much damage.
So that is my plan for the end of the growing season this year.

Viewing Winter’s Damage and Marks of The Deer

Those Pesky Deer

I have ADD when it comes to Spring clean up.   Yesterday I started raking the yard, then I as I was cleaning the garage, I found the and there was wood to move.  and before I knew it I had seven projects going at once.  There is just so much to do when you first get those sunny, warm days after months of nothing but white out the window.

I only moved into this house less than two years ago, so I’ve only had one full summer here to work on the planting.  As I stroll from each garden area to the next I am reminded of how much I have already accomplished in this short amount of time, but I’m also aware of how much there is still to do. I don’t believe Continue reading “Viewing Winter’s Damage and Marks of The Deer”
