Dear Hydrangea Enthusiasts,
Welcome to the September 2005
edition of the Hydrangeas Plus® e-mail newsletter.
Fall is coming, fall is coming! The weather is starting to cool and
it's time to get your hydrangeas ready for their winter sleep. Unless
you're in S. California or Florida. Do hydrangeas every sleep there?
See the commonly asked questions at the end of the newsletter. Lots
of good questions about fall preparation, pruning, fertilizing and protecting
your hydrangeas in containers and in the ground.
Our thoughts and prayers are with the victims of Hurricane Katrina.
We had another busy month here at Hydrangeas Plus®. Our most exciting
was visiting with Dr. Michael Dirr, his wife Bonnie, and research assistant
Vicki Waters and Ph.D. candidate Josh Kardos at our FarWest Trade show this
month. We were hoping that they would all come visit but there is so
much to see here in Oregon. Vicki and Josh were the typical tourists
- being their first time to Oregon, they had to see it all - from the Oregon
coast to the top of Mt. Hood - and all the wonderful scenery in between! We
hope that they can come out again soon and visit our operation.
Dr. Dirr talked about hydrangeas! at the FarWest show opening night
gala - much to all's delight! The pictures were fantastic, his wit sharp
as a tack and his descriptions made everyone drool in excitement for the
next generation of hydrangeas from University of Georgia's breeding program.
Dr. Dirr's visit to Oregon was sponsored by J. Frank Schmitt Company
of Boring, Oregon and our friends, Heritage Seedlings of Salem, Oregon. Some
of Dr. Dirr's favorite hydrangeas that we are growing are:
Macrophyllas Ami Pasquier, Frillibet, Lilacina, Lanarth White, Veitchii,
General Vicomtesse de Vibraye, and Madame Emile Mouillere
Serrata Blue Deckle (remontant)
Quercifolias PeeWee, Sykes' Dwarf, Alice, Allison
Paniculatas Grandiflora, Tardiva.
Some cultivars from the speech were new releases planned for the future that
we hope to bring to you in the coming years...
Paniculatas Chantilly Lace has an upright and graceful
Serrata cross called Painter's Palette is a compact lacecap
with white sepals but green markings, bloom ages pink
Hydrangeas that bloom on new wood (David Ramsey, Decatur
Blue, Oak Hill, Penny Mac)
Bailey's has executed the option to offer one of the seedlings grown from
the control breeding of Endless Summer(tm) and Veitchii. It is called
Blushing Bride (named by Vicki Waters). We have ordered this variety
from Bailey's Nurseries and requested that we be allowed to offer it next
year (as a 2006 pre-release) but being such a small grower, we may not be
able to offer it until the general release in 2007. This fabulous remontant
offering blooms white but will age to pale pink or pale blue as it ages depending
on the pH of the soil. The plant is mildew resistant and a more compact
than the Endless Summer(tm).
Back in stock soon
Most of the hydrangeas are back in stock! Order now to ensure your
first choice will be available. You can select fall planting or spring
planting. If you're unsure about fall planting, use this simple rule
of thumb. Do you have at least 6 (or 8) weeks before your first hard
frost? If yes, fall planting is really the best time to plant. Cooler
temperatures allow the plant's roots to focus on growth not getting water.
Usually this means zones 6 and above are appropriate for fall planting. As
always, mulch your plants for the first few winters to be sure the roots get
established before winter and maximize root growth.
There are just a few of the one year plants not yet available. The
Paniculatas and Quercifolias are always slow to root and sometimes take another
season to get big enough. The true dwarf, Pia, is also a bit on the
small side but I just looked and it is growing very well so expect that one
to be available soon.
Thank you for your patience. If you'd like to be notified when a particular
variety and size is ready, just go to that product online at http://www.hydrangeasplus.com and
enter your email address after clicking on the 'Keep me updated' button and
we'll send you an email when it's ready.
The LADY IN RED (PPAF) are here
We've had lots of questions about new varieties of hydrangeas and we're
please to offer a Dr. Michael Dirr and University of Georgia original. It
took a little while for us to acquire the licensing agreement but next spring,
we'll be offering the Lady in Red hydrangeas! I anticipate we'll have
the one year plants available early next year. We bought some starter
plants just a week ago and while the other hydrangeas are growing like weeds,
we'll have to wait for these new ones to get big enough. This is our
first venture into patented plants so we'll see how successful our first
patented variety will be. We're expect to continue offering Dr. Dirr's
introductions as soon as they are released in the future. This is just
the first of many new and exciting varieties for real life gardens.
We are thrilled to offer you this wonderful hydrangea. I've been
growing a specimen plant for a year and the foliage color is really dynamite.
Dr. Dirr is introducing this first seedling from his first breeding
trials. This is an open pollinated seedling from the wonderful hydrangea
Otaksa. This Lady in Red variety is a strong, vigorous growing hydrangea
with lacecap type blooms of pink or pale blue. The lovely lacecap blooms
aren't finished though. Like many other lacecaps, these will flip upside
and show their red underside. This plant is truly a multi-seasoned hydrangea
- blooms in late spring, aged red blooms in summer and fall color.
This variety was selected for it's fabulous burgundy fall color and it
is mildew resistance even in the southern gardens. Gardeners are going
to love the burgundy leaf veins and stalks, too. Lady in Red is hardy
for zones 6 - 9, needs partial shade (more sun is okay for northern gardens)
and the bloom is slightly pH sensitive. It grows 3 to 5 feet tall
and wide. It reminds me a lot of the serrata family but that
may be the fall leaf color. For a bit more history and information,
check out the website at http://www.ladyinredhydrangea.com.
These plants will be available in Spring 2006 - sorry, they aren't big enough
to ship yet. If you'd like to be notified when they are available, go
to the Lady In Red hydrangea on our website at http://www.hydrangeasplus.com
and enter your email address after you click on the 'Keep me updated' button.
We'll send you an email when they are big enough to ship.
Added USPS Priority Mail service for shipping your hydrangeas
We finally got the website shopping cart set up for another delivery
option for those of you east of the Rocky Mountains. We're using the
USPS Priority Mail service for the fall and see how the plant delivery goes
for you eastern customers. UPS rates just keep going up and up and
even though we are a volume user, we can't get the rates down enough for my
liking. So, until the USPS raise the rates next year, we'll give it
a try. Unfortunately we can't track the package as closely and there
is no guaranteed service. USPS Priority mail saves anywhere from $5
to $15 for smaller orders.

Commonly Asked Questions
Q: I am going to lay down your recommended balanced fertilizer this
fall. Can you give me some guideline as to how much fertilizer I should use.
My hydrangea is about 30" high and 31" in diameter. Last year I think I used
too much with negative results. I am located in NY.
A: Always read the directions but my rule of thumb is 1 tbsp per foot of
hydrangea so approximately 2 1/2 tablespoons for your hydrangea that is 2
1/2 feet tall and wide. Apply the fertilizer around the drip line of
the hydrangea. Avoid getting the fertilizer on the leaves. Water
it in well.
You say you put too much last year. The trick is to know whether the
time release fertilizer is heat released or water released. If you get
lots of rain, the water soluble fertilizer will release more quickly.
If you have warmer than usually temperatures, the heat activated fertilizer
will release quicker. You may not have used too much last year - it
could have been the water or the heat.
Fall is a great time to fertilize with a time release type product.
As the plant begins to slow in top growth, fertilizer will allow root growth
to optimize and store nutrients for the winter. Try not to use one too
high in Nitrogen (the first number in the N-P-K designation for fertilizers).
And, don't wait too long. Too much nitrogen too close to winter and
the stems are weakened and susceptible to frost damage. When your plant
begins to leaf out in the spring, use another application of balanced fertilizer.
Q: Hi. I have potted 2 Madame Emile Mouillere hydrangeas . Can you
tell me what I should do to over winter them? I'm zone 5 or low zone
A: Move them into an unheated garage or basement after they lose
their leaves. Keep them watered - probably once a week is fine.
Just don't let the soil dry out. Although they will be leafless, they
do need a little water.
The key is the roots must not freeze. When hydrangeas are in the ground,
the ground temperatures (zone 6 and above) usually protect them. In
containers, they are much more susceptible because they are above ground
and susceptible to temperature changes. If the pots are too big to
bring indoors, insulate the container. Wrap with a frost blanket (blanket
with a little bit of waterproofing) and cover the plant somehow. The
Madame Emile is one of the hardiest of the macrophylla but it still blooms
on old wood and the old wood must survive in order for you to get blooms.
The old wood is hardy to somewhere between -10 and 10 degrees but if the
roots get that cold, the plants will struggle.
If you do keep them outside and insulate the container, be sure that you
protect the stems of the plant as well. Even though they are dormant,
cold weather (especially in your area) could damage them enough such that
they won't bloom next summer. Hydrangeas do need some old old wood to
survive in order for them to bloom the next summer.
Other tips for protecting hydrangeas from the elements (in ground or in
Use tomato cages or chicken wire and wrap the plant. Once the leaves
drop completely, fill the cages with leaves and garden mulch. Wrap with
tightly woven burlap. Take it off after your last hard frost.
Q: I need your advice. Over the upcoming Labor Day week-end I
have to relocate 3 large hydrangea plants. Two of them -Pee Gee &
La France- I purchased from you 3 years ago; the third one, Limelight, I
bought from another mail order merchant. A new fence is going up near
these plants and since I don't want to lose them I'd like to dig them up
& replant them in a different area. I've never relocated a plant before
and I thought I'd seek your advice on how to proceed. Would you please
help me or let me know where I can find information on moving plants.
A: Transplanting can be done as long as it's cool enough. Hydrangeas
transplant much easier if it's cooler. I've done it in the spring and
the middle of summer but fall is really the ideal time.
Here's some tips...
Hydrangea root systems are fairly shallow and are usually as large as the
spread of the plant. If these are large plants, bind the stems together
gently with twine (this make it easier to move and you don't get as much
breakage). You may also cut the branches back to make them more manageable.
Get as much of the root ball as possible. Dig and transplant the same
day. Your blooms next summer may be a little strange in terms of color and
size the first year after transplanting, too. Water well and mulch
this winter to protect the roots from freezing. Be sure you have
at least 6 (or 8) weeks in the ground before your expected frost date.
Q: Purchased a Gertrude Glahn from you this spring. I am
zone 5 in Rochester, NY. Spectacular specimen. Blooms are now
green with red petal tips. Do I need aluminum sulfate in spring to maintain
the blue? When do I prune and how do I protect for the winter? Thanks
for the help.
A: Do you know the pH of your soil? If you have less than 6.0, aluminum
sulfate probably isn't necessary but spring is the proper time to apply.
As soon as you begin seeing leaf, apply the aluminum sulfate solution.
Don't feel like you have to prune the plant. If it does need shaping,
do it now so that you may get some new growth after you cut. This variety
blooms on old wood and if you prune too much (down into the old wood) then
you won't get blooms next year. Our catalog has instructions on page
Protect your hydrangea with mulch around the base. After the plant
drops its leaves (October for you, perhaps) then wrap the plant with burlap.
Any covering will really be fine. You need to be sure that the old wood
survives the winter so you'll get blooms next year. Hydrangea macrophylla
are hardy to about zero degrees.
Q: I ordered the following items: HY40GLOWINGE 1 year
I planted these last summer, lost a few blooms to the deer. this spring
the growth was all new (the old sticks were brown), I have six lush bushes,
but not a blossom to be found. I'm new to growing them, help?
A: The most common reason why macrophylla hydrangeas don't bloom
is improper pruning. Perhaps the deer did that for you. Most hydrangeas
bloom on old growth or last years wood. If you cut too much of
that old wood off when you prune or you cut that wood too late, you won't
get blooms. See our pruning tips for more info on the website.
My rule of thumb is prune about 6 weeks before your anticipated frost date.
Pruning macrophylla http://www.hydrangeasplus.com/customer/pages.php?pageid=5
The second most common reason why hydrangeas don't bloom is due to cold
weather. The Macrophylla hydrangeas are hardy to about zone 6
(Alpengluhen may be a bit more hardy) between –10 degrees and zero degrees
on the Fahrenheit scale for your Winter low temperatures. If your Winter
temperatures fall between these temperatures, it would be advisable to protect
the hydrangeas to ensure blooms. Again, the old wood of the hydrangea
must survive in order to get blooms the following Summer. If your hydrangea
is dying to the ground every year, (new growth coming from the base) protect
your hydrangeas or consider a hardier hydrangea.
In addition, unseasonably low temperatures after a mild Winter also cause
a lack of blooming on hydrangeas. Again, most macrophylla hydrangeas bloom
on old wood and if the leafed out plant is actively growing and hit by late
Spring frost or an early Winter frost, the buds freeze and the hydrangea won't
Or if the deer ate them in the spring, and there wasn't enough old wood
left for blooming.
Fertilizing too much can also stunt your blooms. Too much nitrogen
and you get a healthy plant with beautiful foliage, but no blooms. Use
a more balanced fertilizer and see our info about fertilizing hydrangeas.
Finally, hydrangeas need some sun to bloom. Remember morning sun and
afternoon shade is ideal for most Macrophylla hydrangeas.
Q: In your last newsletter you said it's time for a haircut for
the hydrangeas, Mine are huge but had little growth on 3, which are the largest
ones. What kind of haircut?
A: Sorry for my use of un-plant-like talk. By haircut, I mean
a sever pruning. This can be done in the summer so that the plant is
allowed to put on good growth before going dormant for winter. Most
mophead and lacecap hydrangeas bloom on old wood and if you cut severely in
the fall you won't get blooms. But if your hydrangea is out of control
and huge and overgrown, a 'haircut' is a great idea. Hydrangeas
are growing their fastest right now and even the most cut back hydrangeas
will develop new leaves in about 2 - 3 weeks.
Are your hydrangeas macrophylla? This is the family of lacecaps and
mopheads and because they bloom on old wood, you need to be sure there is
some current year's growth left on the plant before fall.
