Dear Hydrangea Enthusiasts,
Welcome!
Welcome to the November 2005 edition of our Hydrangeas Plus®
newsletter. We hope that this newsletter finds you and your family
healthy and happy.
Rain is upon us here in the Willamette Valley. I saw the rain gauge
and in just 36 hours we're up to 4 inches of rain! The nursery is holding
up well. Hydrangeas have begun their decent into dormancy with wonderful
and colorful changes in the leaf and bloom. My serrata Blue Deckle
outside the office is more spectacular (in my opinion) now that it was in
peak bloom. Reds and yellow leaves really highlight this fantastic
cultivar. Another one of my favorites that I can see from my office
is the Oakleaf Snowflake. That burgundy red leaf can be seen from across
the nursery. Everyone should have an oakleaf - even if you don't have
room for it.
In case I forget with all the Holiday hoopla, thank you all for a great year.
Our family and employees thank you for your business. Your comments
have been wonderful and we appreciate your emails and your successes and

Winter is coming
In case you didn't know, hydrangeas are deciduous and will lose their
leaves during the winter months. Warmer zones (like areas in California
and Florida) may not experience total leaf loss. In fact, warmer climates
may have hydrangeas that keep their leaves all year long and just discolor.
You may remove those leaves if you don't like the discoloration or
wait until warmer days when the new leaves will push the old leaves off
the plant.
In most areas (zone 6b and above), cold weather shouldn't harm your macrophylla
(mophead and lacecap) hydrangeas. The Paniculata, Arborescens, climbing
Petiolaris and Oakleaf are all much hardier and should be safe to zone 4
without protection. Severe cold weather after periods of unseasonably
warm weather could be a problem and cause your plants not to bloom the following
summer. Here in Oregon, our typical fall season is ideal for hydrangeas
with a gradual decrease in temperatures. With the gradual decline,
the hydrangeas are slowly going dormant and losing their leaves. We
get the most fabulous color changes for this very reason. After your
first hard frost, leaves should begin to fall.
Remember, most macrophyllas bloom on old wood so to ensure blooms the
following summer, old growth (this year's current growth) needs to survive
the winter to produce buds next year. Most macrophylla types are bud
hardy in the range of 0 degrees to -10 degrees. If you want to give
you hydrangeas some added winter protection, just to be safe, there are several
things you can do to protect your hydrangeas. See our commonly asked
question section for tips.
New varieties coming, new varieties are coming
We have already let the cat out of the bag, so to speak, with the
Lady in Red hydrangea for 2006. The fall color on this variety is better
than any I've seen. Order early to make sure you get your Lady in Red
hydrangea. They are available now or for spring shipment.
I have just received confirmation from Bailey's Nursery that we were allocated
some of the Blushing Bride hydrangea - the white, new wood bloomer. This
fabulous bred hydrangea is a controlled cross between Endless Summer and
Veitchii. The ship date is sometime in July of 2006 but we were only
able to get the 3 year size so watch for those available next summer and
fall. I acquired a test specimen and it is still blooming for me. Yes,
in November.
Now, what else will we offer for next year??? Just wait and see.
Commonly Asked Questions
Q: We've been experiencing a lot of fog lately and powdery
mildew is infecting the leaves of the plants. There's a lot of air
circulation around the plants and I have them under full shade. Would
it help to put them where they can get some sun? Would it help if I
let them dry between waterings?
A: It is that time of year that the powdery mildew is upon us.
The mildew is more prevalent when you have warm days and cool nights.
If it occurs in the fall, the leaves will fall off eventually and the fungus
will go away in the winter months. But, it is still annoying.
Since we are so late in the season, I would avoid doing anything chemically
as the leaves will soon fall off as the plant goes dormant.
If you experience powdery mildew in the spring or in an area where hydrangeas
don't go completely leafless, you may spray a phosphate or homemade baking
soda product or other fungicide. The best acting products contain
sulfur, fenarimol, dinocap, triadimifon or benomyl. Refer to the instructions
on the package to determine method and timing of application. Weather
conditions such as temperature and humidity are important factors when determining
when to apply fungicides.
It is most important is keeping the mildew from spreading. Remove
the infected leaves or any that have fallen from the plant. Remove
mulch and replace with clean mulch. Remove any unnecessary vegetation
away from the base of the plants. If you caught it soon enough, apply
olive oil or horticulture oil to the leaves and rub away the mildew.
It may leave black spots if the mildew has been on the leaf for a while.
I read somewhere that one plant can generate 100,000 spores in
just one day so catching it early is best.
Here are some other tips for fighting Powdery Mildew:
- Keep the area under the plant free from fallen leaves and debris
- Limit watering just to prevent the plant from wilting (don't overwater)
- Water in the morning hours
- Move the plants to a sunnier location
- Give plants plenty of room to grow
Here is a recipe for a homemade fungus fighter:
Mix a solution of 1 teaspoon baking soda in 1 quart of warm water in a
small plastic spray bottle. Add 1/2 teaspoon of either liquid dish soap
or insecticidal soap to help the solution cling to the foliage. Spray infected
plants thoroughly on both sides of the leaves every 5 to 10 days.
Q: i live in "way upstate new york" just south of ottawa
..what should i do to ready my hydrangea for the winter? ..when do i mulch?
..
A: Perfect timing! I'm working on the newsletter
for next month and the winterizing is the subject of the month. If
you have Paniculatas, Arborescens, Oakleaf or climbing hydrangeas, they should
be just fine with mulching around the base of the plant after leaf drop.
If you macrophylla (mophead and lacecap) hydrangeas had trouble blooming
this year, I would suggest some winter protection.
For the macrophylla (mopheads and lacecaps) wait until the leaves fall off
or fall off just to the touch. That should be a week or so after your
first hard frost. I suspect this may be the perfect time for you or
close to it.. Take off the spent blooms if you haven't already cut
them. Loosely tie the branches together with twine.
For your hydrangea to bloom next summer, the old wood needs to survive.
The best way for that old wood to survive the winter is to cover the plant
and protect it from the cold, freezing temperatures. Hydrangeas should
be all right to about 10 degrees. However, the macrophylla types are
especially susceptible to drastic changes in temperatures (unseasonable high
temperatures followed by extreme cold).
There are a variety of ways to protect hydrangeas. Some people can
just get away with wrapping the tied up branches with tightly woven burlap.
If you get lots of snow cover and the hydrangeas will be mostly covered,
the snow and burlap with insulate them. If hydrangeas are in a very
protected area, the burlap could be enough to protect them.
If you don't want to take any chances, here are some extended protection
ideas. Use a tomato cage or similar structure (recently, zone 5 NY
customer told me she uses tall Peony and Dahlia cages).
After structure is in place, fill with composted leaves, leaf or bark mulch.
Wrap the whole structure with burlap. You can also cut up old plastic
garbage cans and form them around the plants to eliminate the need for the
burlap. If your plants aren't too big, use old nursery containers.
Before my parents moved here to the Willamette Valley, they lived in a colder
region and used 5 gallon containers on their hydrangeas with rocks on top
to keep them from blowing away.
Remove the structure after your last hard frost in the spring. You
may still want to have some frost protection sheets to throw over the plants
in case of a late spring frost but you are probably safe around May 1st.
NOTE FROM ZONE 5 - IL - Just wanted to let you know, since some zone 4-5
questions were on the newsletter, that I have had good luck also using Wilt
Pruf in addition to wrapping my hydrangeas in zone 5. Also, I have
had good luck using floating (vegetable) row cover instead of burlap.
I hope that helps. Thank you for your question.
Q: I am a Master Gardener Intern here in W. Massachusetts, and
we had a booth at the big Eastern States Exposition. We receive MANY
questions about hydrangeas--more than about anything else, I think!
Mostly, "Why didn't they bloom this year". Indeed, my own 'Endless
Summer' grew well but bloomed less than it's first year (last summer).
Of course we asked the obvious questions like: Enough sun? When did you prune?
DId you fertilize? What about the soil? Etc.. But I'm afraid
none of us really had a clue what exactly to tell them. We could only
hint at "too hard a winter, not enough sun, pruned wrong time, etc."
I would love more thoughts that I might pass on to the other Master Gardeners
here in Western Mass.
A: You really touched on all the possibilities.
I can't think of another reason.
A question you can ask is 'did the hydrangea grow only from the base of the
plant?' If that's the case, most hydrangeas bloom on old wood so if
all the old wood didn't come back, there are fewer blooms. If you had
a hard winter, that's probably the reason.
The hydrangeas like Endless Summer to bloom on new wood, should bloom no
matter what the weather. Unless of course, too much fertilizer, poor
soil, not enough water, etc - all the other reasons you mention.
When I talk with people on the phone, you really have to go through all the
possibilities. Most often for me discussions with customer lead to
trouble because of pruning or weather.
Here's my answer for hydrangeas that don't bloom
The most common reason why macrophylla (mophead and lacecap) hydrangeas don't
bloom is improper pruning. Most hydrangeas bloom on old growth or last
year's 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.
The second most common reason why hydrangeas don't bloom is due to cold weather.
This may be your issue. The Macrophylla hydrangeas are hardy to about
zone 6 or between –10 degrees and zero degrees on the Fahrenheit scale for
your Winter low temperatures. Some varieties are hardy to zone 5.
If your Winter temperatures fall between these temperatures for long periods
of time, 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, 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 bloom.
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 balanced fertilizer, time release like Osmocote just a few times a
year - Spring and early fall. See our info about fertilizing hydrangeas
on the website, too.
Finally, hydrangeas need some sun to bloom. I think a few hours of
sun is perfect.
I hope that helps. Please let me know if I can be of further assistance.
Q: I HAVE JUST TRANSPLANTED 5 NIKKO BLUE, SORT OF!
AND 5 WHITE/GREEN HYDRANGEAS. WHAT SHOULD I FEED THEM NOW OR LATER IF ANYTHING.?
I AM MOVING AN OAK LEAF, SPRWWLING 10 FOOT HYDRANGEA AS WELL. I HAVE
NO IDEA WHAT IT WILL DO AS IT WAS GROWING OUT FROM UNDER SOME FUR TREES.
I DOUBT IF IT WILL SUPPORT ITSELF, AND DON'T KNOW IF IT IS A CLIMBER!
THE WOODY STEMS ARE ABOUT 3 TO 4 INCHES IN DIAMETER. ANY HELP WOULD
BE GREAT.
A: Don't' worry about feeding the newly transplanted
Nikkos right now. Too much nitrogen absorbed and the stems and stalks
become weak and very susceptible to frost damage. Mulch the base of
the plants as soon as the leaves fall off (should be sometime in the next
month or so). The mulching will keep the roots and ground warm for
some extra time so the roots can continue to establish before the whole plant
(roots and all) go dormant for the winter sleep. In the spring, when
leaves start peeking out, fertilize with a balanced, time release fertilizer.
16-16-16 or 10-10-10, something like that. But, don't rush out and buy something
special, any shrub food will be fine. If you get yellowing leaves in
the late spring, add another dose of fertilizer at that time.
That is a huge Oakleaf. Cut it back so that you cut all the stem off
except for one big, pretty leaf node. The hydrangeas are so much easier
to move if they are smaller. Wrap the branches loosely with twine and
tie up the branches. This will make it easier to see under the plant
and where the roots are. Hydrangeas' roots are fairly shallow and usually
are as wide as the spread of the plant. A 10 foot hydrangea could have
a pretty large root system. Get as much of the roots as possible.
Plant it in the new location quickly. You may also cut up the hydrangea
and make several plants. Most hydrangeas will adjust very well.
Oakleaf are sometimes a little sensitive to lots of root movement in the
summer months particularly.
Thank you for your question. Please let me know if I can be of further
assistance.
Q: This summer a hydrangea that was here (and full
grown, and doing great) when we moved in 2 years ago died suddenly, even
though surrounded by hydrangeas I had planted more recently which were thriving.
The leaves drooped straight down, turned brown, and fell off. Now it seems
to be putting out some new growth at the base of the plant, but the rest
of the plant is completely brown and dead-looking. Is this a common thing?
I was worried it was something contagious but my other hydrangeas are still
doing great. Thanks for any comments!
A: Sometimes hydrangeas do die. I had two die
this year. Usually it turns out to be environmental not fungus. I
call it USER ERROR in my case - sprinklers weren't reaching them.
Most often, it's a water issue. It can be too much or too little.
Your description sounds like too much water. It could be too little
water as well - the signs are so close to each other. Perhaps the run
off from the sprinklers or a broken water line could have caused this trouble.
Or watering program missed the hydrangea. It does take a lot to totally
kill off a hydrangea as you can tell by the new growth. Perhaps the
problem fixed itself. Cut off all the dead branches. It may recover
and be perfectly healthy next year.
When hydrangeas have too much water, they never perk up - they always look
droopy, even after a good watering.
When hydrangeas need more water, they will perk up within an hour or two
of watering.
This year was a bad year for field mice, voles and moles here in the Willamette
Valley because the winter was so mild. They could have eaten the roots
of the hydrangea but you would have seen other signs beside just the hydrangea's
demise.
I hope that helps. Please let me know if I can help with anything else.
