Dear Hydrangea Enthusiasts,
Welcome
Welcome to the April 2013 edition of the Hydrangeas Plus® e-mail
newsletter. We hope that you have hydrangeas on the brain!
We are starting to see some buds on the serrata and early blooming
macrophylla types. It’s a little early for us but with the
beautiful (non-rain) weather we’ve been having, it is no wonder these
plants are flourishing.
Kristin was a little late getting this newsletter together. Sorry
for being so tardy. We’re doing inventory and taxes – her two
favorite April activities. Really!
Spring tip – Your Hydrangeas and soil
I always talk about the importance of good soil and its ability to
drain well. Most areas don’t have perfect soil but there are lots
of things you can do to improve your soil and grow better
hydrangeas. Good soil is important for root growth and supplying
water to the hydrangeas leaf and stem structure but most importantly,
the flowers. Here are a few tests to see what kind of soil you
have in your garden.
Drainage test – Dig a hole about 6 inches deep and one foot wide and
fill it entirely with water. Let the water drain out of the hole
completely. Fill the hole again and record the time it takes to
drain the second time.
If the water drains in three hours or less, your soil is most likely
draining too quickly. Chances are your soil is somewhat
sandy. If the water drains in four to six hours, your soil is
draining just perfectly. You have rich, great soil for
hydrangeas. If the water drains in eight hours or more, the soil
has poor drainage typically common with clay-like soil.
Root test – Dig gently around a selected plant, preferably an annual
weed or something that was going to moved and thrown out anyway.
Pull out the plant from the soil gently making sure that the root
system stays intact. Check the root system of the plant. If
there are many fine strands of roots that are bright white and healthy
in appearance, you have great soil. If the roots are stunted,
lopsided or otherwise dingy, you have poor soil.
Compact test – Spear a wire rod (we use a 4mm or ¼” gage wire) into the
soil. Mark the depth of penetration – the sooner it bends, the
more compact the soil. The ideal condition for most shrubs is
about one foot.
Dirty Thumb test – Dig a hole about 6 to 10 inches deep. Separate
a section of your soil, intact, about the size of your two palms cupped
together. Is your soil granular, powdery or clumpy? The
best type of soil will clump in small but breakable consistencies.
Let’s say you your soil didn’t pass one test (or very few). Here
are some great components that can be added to improve your soil:
Grass clippings, clean and disease free leaves, homemade compost, aged
manure, mushroom compost, store bought potting mix. Mix these
into the soil in early spring a few weeks before you begin planting or
as a mulch after planting. For more information, call your local
university extension office.

Our annual ‘Overstocks’ spring sale is April 27th-May 11th, 10am to 4pm
everyday. We’ll have lots of hydrangeas but not every
variety. This is our annual “Spring Cleaning” sale where we sell
everything we have left over and make room for more plants. I’m
not sure what we’ll have for sure so you’ll just have to wait and
see. There are directions at
http://www.hydrangeasplus.com/directions.html. No presales will
be allowed and we ask that pets stay at home for safety reasons.
We have more than just hydrangeas, too.
Mother’s day specials will be online in a few weeks (after we set up
for the spring sale).
Here are some other upcoming dates to mark on your calendar!
June 15th we’ll be selling plants at Sebright Gardens in Salem, OR
July 15th we’ll be selling plants at Dancing Oaks Nursery in Monmouth,

Commonly Asked Questions (back by
popular demand!)
Q: Hi, I purchased some
hydrangeas from the grocery store. I know that two of them are pink
macrophylla. Can these be planted outside? I live in zone 5,6 in
upstate NY. The other three that I bought do not have a tag that say
which kind they are? So I guess my other question is can all hydrangeas
be planted outside, or is there a hydrangea that is just a houseplant?
A: The forced varieties are really similar to the
outdoor varieties and it could grow like one eventually. I’m
really not an expert on growing hydrangeas indoor. I buy the
grocery store varieties during the winter so there are at least some
blooms but they are usually moved outdoors within the year.
Hydrangeas like slightly acidic soil. In the artificial media
that most of these forced plants are grown, you'll need to keep the
acidity level up (i.e., the pH level down). Tea leaves, coffee
grounds or aluminum sulfate can help because they are acidic.
Most varieties used in florist trade grow very quickly and may not be
healthy if grown inside without moving the plant to a larger pot every
few months. You may need to cut off the blooms because they can’t
get enough water. Commercial growers use growth regulators to
keep them small, too. Plants need to outgrow this chemical to
behave like normal garden hydrangeas.
If you do move it outside, be sure that you don't move it until the
last chance of cold weather has passed and there is no chance of any
frost. My general rule of thumb is don't move the forced
hydrangea outside until the outside hydrangeas are at the same stage of
leaf. That can be April, May or June, depending on your area.
Q: Help!! The slugs are eating my
hydrangeas. What do I do?
A: Slugs and snails love hydrangeas. My recommendation is
get some slug and snail bait. There are many brands that are not
harmful to pets or children (Sluggo and Worryfree). There are
some new brands on the market that are made with iron phosphate that
actually help plants grow but they are not as effective as these
chemical alternatives. As for natural solutions, you may pick
them off and cut them with sharp pruners early in the morning before
the sun is completely out. Some other less tiring methods are
broken eggshells, a small flat container full of fresh beer, a 2-liter
plastic bottle with the top cut off with just a little beer at one end,
or add frogs, toads or ducks to your garden – they love slugs and
snails.
Q: I live in zone 6, the soil around
my house is not really acidic but I would like to plant one of your
blue hydrangeas. Do you have any tips on how to acidify my soil
to help ensure a healthy blue color?
A: Acidity levels need to be around 5.5 - 6.0 on the pH
scale. Buy a meter that will tell you your acidity level.
I've seen them around Portland, OR for about $20. This will tell
you what works for you and what doesn't in terms of changing the pH.
The most common method for getting blue hydrangeas is aluminum
sulfate. The aluminum is what the hydrangea actually absorbs to
turn the pigments blue and the sulfate will lower the pH and allow the
hydrangea to more readily absorb the aluminum. Be aware that you
can burn both new and established plants by applying too much or too
often. For a more natural method, apply coffee grounds, evergreen
tree needles, citrus peel rinds, rusty nails or pennies. These
things will all lower the pH. With the increasing popularity of
blueberries in the garden, garden sulfur (Hollytone) is often available
in your local garden centers in the spring. It is great for
hydrangeas too!
Fertilize with a product that is very low in Phosphate. Phosphate
limits the absorption of aluminum. Check your water. If you
are on well water, the water could be very alkaline and all the above
items won't work well if you keep irrigating with sweet (alkaline)
water.
Pick the right variety. Some hydrangeas will never get deep dark
blue no matter what you do. The deepest possible blues are GB
Kuhnert, Altona, Europa, Enziandom, Hamburg, Marechal Foch, and
Mathilda Gutges (just to name a few)
