Weather Outlook For Spring 2007

You know that old saying: ” Everybody talks about the weather, but no one does anything about it!” 🙂 Not much can be done about controlling the weather quite yet, but there are a lot of people trying to predict it.

Climatologists at the National Oceanic and Atmospheric Administration (NOAA) have announced their 2007 Spring Outlook. This forecast is their best educated guess about the weather from April through June.

Taking a quick look at the maps, it seems that our part of the country will have a pretty average spring.

The NOAA website is the place I go every day to get my weather forecasts. There is a ton of information there. If you would like more detail than the simplified forecasts from The Weather Channel then by all means visit their site. After all, it is ours, we pay for it through our taxes. It is an agency of the Commerse Department of the United States.

NOAA is celebrating 200 years of service to our country this year. It traces its roots back to 1807 when Thomas Jefferson established the Survey of the Coast.

I remember several months ago, there was some talk about selling our weather service to a private company. 😕 I’m not so sure if that is a good idea. It sounds sort of like selling the Army or the Grand Canyon.

That’s enough for now… my bursitis tells me we are in for a change in the weather!

Saints Preserve Us!

After all the anticipation, after the long time between holidays, March 17th has finally arrived. This is the feast day of the Patron Saint of gardeners. We as gardeners love the color green, to me it represents abundant plant life and vitality.

The reason why this day has been made a Saint’s day for gardeners was lost centuries ago. The most common explanation is that in Europe, where this tradition began, March 17th historically has had good weather. So many people sowed the first seeds of the season into their gardens. Here in Southern Michigan mid-March is early even for cold tolerant crops. By the way, green beer is a modern invention and really has nothing to do with this Saint.

Born in 626 AD, in Belgium, Saint Gertrude of Nivelles was a devout Christian even at an early age. At ten years of age she refused to marry a nobleman and devoted her life to her religion. When she was only twenty years old she became Abbottess of her monastery in Nivellis. She lived to be only 33 years old, probably due to overwork exacerbated by her austere living conditions.

Saint Gertrude is also patroness of travelers, she was known all over the continent for her hospitality to travelers. She gave especially generous assistance to Irish missionaries who often traveled through the area. She was friends with Saints Follian and Ultran and helped them establish a monastery at Fosse. Curiously, Saint Gertrude’s sister, Begga, was also canonized a Saint, her feast day being December 17.

Saint Gertrude’s popularity grew during the middle ages and she was particularly beloved in Belgium, Germany and Poland. In addition to gardeners and travelers, she eventually became patroness to herbalists and people who love cats. Often her name was invoked against mice or other rodents whenever an infestation was discovered.

Many times, pictures of Saints have no identifing name on them because artists would use symbols to identify their subjects. If you see an old statue or painting of a woman, standing in a garden, carrying a staff with a mouse crawling up, that’s Saint Gertrude!

So… Happy Saint Gertrude’s Day!

70 degrees, Bees and Lettuce

Did you get a chance to go outside today?  I did. 

 

The snow was melting rapidly this morning as the temperature began to rise up to 70 degrees.  It was a great opportunity to check out how things fared over the winter.

 

My first stop was the bee hives.  All 8 hives had made it through the winter.  I always expect one or two of the colonies to not survive the winter, so this was a pleasant discovery.  The bees were joyfully taking their first spring flight in the 70 degree air and basking in the sun on the side of the hive boxes.

 

My next stop was the vegetable garden, as regular readers of this blog know, we have around 125 raised beds.  Most of the beds were still frozen, some had snow-melt water on the surface because the soil had not completely thawed.

 

One bed, much to my delight, still had growing spinach!  Every spinach plant in that bed was alive and making new growth.  What makes this all the more surprising is the fact that this bed was not mulched or covered in any way!  Of course I just had to taste some, so I picked a few leaves… they were delicious…and super-sweet.  I mean almost sugary!  Apparently, the spinach plants, as a winter survival tactic, had increased the amount of sugars and other nutrients in their leaves and crowns.  This kept the individual plant cells from forming ice crystals and bursting their cell walls.  These will make the most nutricious salad of the season.

 

Last fall we had covered 4 beds with home-made plastic “mini-greenhouses”.  These, of course, were the warmest of the garden beds.  I stuck my soil thermometer in several spots to depth of 5 or 6 inches and found that the soil temperatures ranged from a high of 44 degrees F near the center of the bed to a low of 32 degrees at the corners.  Actually, the corners were still frozen at a depth of 3 or 4 inches.

 

Hey, 44 degrees is good enough for me! 🙂  I cleared out a few frozen bib lettuce plants leftover from last fall, raked the surface level and sowed new lettuce seeds. Lettuce is a cool weather plant and is able to germinate fairly well when soil temperatures are in the 40’s.  Since this particular bed will be protected by the bed cover,  the planting will have a good chance of producing a successfull early lettuce crop.  If not, I’m only out the cost of a few seeds.

 

The seed I used was a mixture called “All Star Gourmet” from Johnny’s Selected Seeds.  This mix contains 4 different green leaf lettuce varieties and 4 red leaf.

 

If all goes according to plan we will be harvesting our first outdoor lettuce in a few weeks. 

 

And so, another season begins…

Phyllis, Don’t Toss Out That Amaryllis !

We are well into the Amaryllis bloom season at this point in time. Some of our Amaryllis bulbs began blooming between Thanksgiving and Christmas. We have had continuous blossoms since then and the last of our Amaryllis are beginning to bloom right now. It won’t be long until they are completely done.

So, now what? What do you do with an Amyrillis once it’s done blooming?

There is no state law requiring you to keep it. Many people simply toss them out once they’re finished. However, if you follow just a few simple steps, your Amaryllis can be coaxed into blooming again next year. A lot of the bulbs we gave away during the Christmas season are now being returned to us for re-blooming.

The first step is to cut off the flower stalk after the flowers have withered. Then just simpley treat the remaining plant just like a houseplant. Keep the soil somewhat moist and fertilize it once a month with soluble house plant fertilizer. The main idea is to keep it growing, the more vigorous the growth, the more spectacular the subsequent flowering.

Over Memorial Day weekend, (mark it on your calender) set the plant outside in a brightly lit spot. Dappled shade will do nicely. Don’t let it get sunburned 8). You can leave it right in its pot if you like and re-pot every three years or so. Or you can do as we do and plant the bulb into a garden bed. Keep up the fertilizing and watering regimen.

Some time around Labor Day, your Amaryllis will start to turn yellow. This is normal. The yellowing is an indication the the plant wants to rest and go into a dormant period. Stop watering it at that point and let the leaves die back. Cut the withered leaves to about an inch above the bulb in the neck region.

The dormant bulb needs to be placed in a dry area (no water at all) for about 8-10 weeks. Be sure they don’t freeze.

Sometime around Thanksgiving you can wake up your Amaryllis bulb by placing them into a bright spot and giving it some water. It will re-sprout its leaves and bloom again.

With all that being said, I have seen Amaryllis re-bloom again without all of these steps being adheared to exactly. I have found that as long as the bulb has made some growth (or at least has not lost size) it will more than likely blossom again.

So Phyllis, why not keep that Amaryllis? It really will make a nice houseplant.

On the Science Of Gardening

Yesterday afternoon, while working in the greenhouse, I was listening to one of my favorite radio programs; “Science Friday” on National Public Radio. Each week, for two hours, the host Ira Flatow and his guests discuss current scientific developments. The second hour on Friday was devoted to gardening. Gardening actually does involve a large amount of science, for example, the absorption of minerals, the creation of sugar during photosynthesis and the exchange of minerals and sugars during the growing processes.

Ira’s guests on the gardening segment were: Tanya Denkela author of The Gardener’s A-Z Guide to Growing Organic Food and David Ellis, Director of Communications for the American Horticultural Society and editor of ” American Gardener Magazine”. They were later joined by writer and radio producer Dan Charles author of Lords of the Harvest, a book detailing the development of the first generation of genetically engineered crops.

A lot of ground was covered in this segment, it hardly felt like an hour had gone by. You certainly don’t have to be a scientist to enjoy this program as Ira makes sure the information is presented in a way we all can understand.

I’m hoping Ira Flatow will present more programs on gardening from the scientific viewpoint. For me, it was a nice change of pace from all of the lighter gardening programs we hear on the radio. If you missed Friday’s program, it will be available via podcast.

I listen to “Science Friday” Fridays from 2-4 pm on WUOM 91.7 FM public radio from the University of Michigan.

Butterfly’s Favorite

Today, the first of the Butterfly Weed seeds we sowed last week sprouted. This event was the culmination of a five week process that was needed in order for them to germinate.

Asclepias tuberosa gets the name Butterfly Weed from the fact that butterflies love these plants as much as people do. Monarch butterflies often visit this plant because it is in the milkweed family.
This hardy perennial produces dense clusters of blossoms ranging in color from yellow to orange to red that appear in June and July. They make a good cut flower.

As you might have guessed, there is a down-side to growing these garden favorites; that being the five week process I mentioned earlier.

It all starts with a four week process know as “stratification”. It is during this period we try to mimick winter and the early spring snow melt which is needed before the seed is able to geminate. This happens fairly often in the plant world and is needed by many hardy perennials.

We start out by placing the seed between two sheets of wet paper towels. The paper toweling gets placed into a Zip-Loc bag, then the whole thing goes into the crisper of the refrigerator. There the seeds are fooled into thinking the winter is ending and the warm spring will soon be here.

Last week, after four weeks, the seeds were removed from the crisper. We sowed the seeds on the surface of our planting mix without covering them because, in addtion to stratification, they also need sunlight to sprout. So, now, they have the 70 degree warmth they need to begin growing in the greenhouse.

Not all seed catalogs or nurseries for that matter offer Asclepias seed or plants. It may be due to the difficulty in the germination process. There is still time to order seeds if you want to try growing them yourself. We got ours from Stokes Seeds . Park’s Seeds offer them as well.

By starting the seeds this early we can be sure they will blossom this season instead of having to wait until next year. The seedlings will be planted in the garden in May along with the rest of our flowers.

A Cold Tree Walk

Some folks were tired of being cooped up inside. They joined me on my walk in the woods identifying different trees at Matthaei Botanical Gardeens. It was a cold day on Saturday but over 20 people signed up for my class. We spent almost 2 hours walking the trails and identified over 20 trees, shrubs and vines.

One tree that we saw often on our walk was the Tulip Tree, also called Yellow Poplar. It’s an important lumber tree particularly down south. It grows a very straight trunk and if it’s surrouned by other trees, the lower branches die and fall off early , so it has few knot-holes , thus making smooth knot-hole free boards.

We also saw lots of White Ash. Unfortunately, most of them were dead from the Emerald Ash Borer. Washtenaw County, where the Gardens is, was one of the first counties to be quarantined because of the E.A.B.. So all of our big Ash trees are dead. At the Gardens many were cut down near the trails for safety reasons. On the downed trees we could easily see the tunnels left by the borer larvae. They chewed their way through the cambium layer right under the bark. The cambium is the essential vascular system that keeps the tree alive.

We also looked on the bark for the telltale “D” shaped holes where the borer entered the tree. I hadn’t realized we had so many Ash Trees at the Gardens until they stood out as dead trees.

The death of this magnificient tree is going to make a lot of botanists and tree lovers feel very negative about globilization. (The E.A.B. was brought into our country inside wood packing cases from a foreign country.)

The group was awed by the big Poison Ivy vines that we saw. Some were almost 3 inches thick and thirty feet high, growing up some tall trees. P.I. has rootlets all along the vine that attach to the trunk of the tree. It is not a parasite because it doesn’t steal any nutrients from the tree. The short rootlets just anchor the vine to the trees so it can grow upward to the sunlight. We saw branches of the vine sticking out, which differentiates the P.I. from the Virginia Creeper vine, which also has rootlets for clinging to the bark of a tree. Poison Ivy has 3 leaflets. Virginia Creeper has 5 leafllets and is not poisonous. Did you know that a person can get the rash from P.I. even in the winter time and even from the roots in the ground. The oils that irritate us are present even when the plant is dormant.

Once I get started in the woods, I tend to want to keep on going to see what is around the next bend. But we were cold after a hour and a half, so we started on back to the building.

There are a number of good Tree identification guides that you can use. The one we like best at the Gardens is “Michigan Trees” by Barnes and Wagner. Both were professors at University of Michigan. Dr. Wagner, sadly, died a few years ago. But Barnes is still giving classes with the Community Education Program at the Matthaei Botanical Gardens.

Bye for now, Judy

Kitty Greens

From what I gather, cats require a certain amount of “green food” in their diet to keep their digestive tract on track and their general health…umm…healthy.

Because our cat, Friskie, prefers to stay in the house most of the time, Judy suggested a while back that we grow some “greens” for her ( the cat I mean, Judy already gets lettuce from the greenhouse ).

So, several days ago I liberated one of our used greenhouse flats from the recycling pile and sowed a crop of “cat grass”.

I decided to use some left over grass seed we had saved from last year. I just filled the flat with our regular starting mix then, in half of the flat I planted a fescue variety and on the other, a bent-grass variety.

Now, about a week and a half later, the grass is about 2-3 inches high. It is very soft and tender and does look good enough to eat, especially the bent-grass. This afternoon, when we brought the flat into the house, it took Friskie all of 2 minutes to find that lucsious tray of “kitty salad” and start chowing down on it.

We plan to just leave it in the house in an out of the way spot so she can have some whenever she wants… her own fresh salad bar!!

Now, where did I put that bottle of Neuman’s Own……?

2008 Perennial of the Year

It’s taken me this long to consistently write “2007” on my checks and now we have to be concerned about 2008 ! 🙂 A person has to keep up with the latest gardening news or it will pass you by. A good place to do that, my fellow gardeners, is right here on All Things Green.

The Perennial Plant Association has announced their annual 😉 “Perennial Plant of the Year” for 2008. It is…drum roll please…. Geranium ‘ Rozanne ‘.

This wonderful plant grows in a mound shape about 2 feet high and has lavender-blue flowers that are relatively large for a Geranium. It is hardy in our area and should make a fine addition to anyone’s landscape.

I have always loved the blue-flowered Geranium varieties but am often a little disappointed about their short blossoming period . ‘Rozanne’ , however, begins blooming in June and keeps right on blooming until September, making it one of the longer blooming Geranium out there. It prefers well drained soil and full sun but will adapt to partial shade.

Keep in mind that ‘Rozanne’ is a true Geranium ( sometimes called “Cranesbill” ) and should not be confused with Pelargonium, the annual that most folks call “geranium”.

Now, before you even ask, the 2007 ” Perennial of the Year ” is a catmint ( Nepita ) called ‘Walker’s Low’….but that’s old news ;).

Growing Easter Lilies is Cool!

In one of my first posts on this blog, I mentioned something about growing Easter Lilies. At this point in time, we have about 200 Easter Lilies in the greenhouse.

As you are aware Easter Sunday occures differently on the calender every year. Some years we have an early Easter, some years a late Easter. The challenge in growing Easter Lilies is to get them to bloom on, or a day or two before Easter Sunday.

The last three weeks in the greenhouse have been pretty uncomfortable. Because the Lilies were ahead of schedule, the heat had to be turned down to 50 degrees ( plus or minus a couple of degrees ) to slow down their development. This is our seventh year of growing Easter Lilies and it is the first time I had to take such drastic measures.

On those clear sunny days we had recently, the solar gain would start to build and the temperature inside the greenhouse would rise above the prescibed levels. That caused our automatic vents to open and a blast of cold winter air would come rushing in. Anyone working inside transplanting seedlings or working on seed orders, would have to brace themselves against the cold. This opening and closing of the vents went on all day until sundown when the solar heat was no longer a factor and the temperatures stabilized.

We wore our winter coats for 3 weeks inside the greenhouse… until today. I took some measurements, made some quick calculations and decided that it was time to resume the normal Easter Lily growing temperature of 63 degrees. We were finally able to shed our coats. There was still some opening and closing of the vents but since the growing temperature was 13 degrees higher, they didn’t have to open up nearly so often.

At this point in their development our Easter Lillies range from 12 to14 inches in height. I’ll keep you posted on their progress as we make our way through Lent and on to Easter.

In the meantime Mardi Gras is on its way…laissez les bon ton roulette!!
