Awaiting the Vernal EquinoxAdd to My Luxx Living
“May flowers always line your path and sunshine light your day. May songbirds serenade you every step along the way. May a rainbow run beside you in a sky that’s always blue. And may happiness fill your heart each day your whole life through.” ~ Irish Blessing
The March equinox will occur in March 2015 on the 20th at 22:45 UTC or 10:45 PM DST.
This marks the beginning of spring in the northern hemisphere and fall (autumn) in the southern hemisphere from an astronomical viewpoint. The March equinox is the movement when the sun crosses the true celestial equator – or the line in the sky above the earth’s equator – from south to north, around March 20 (or March 21) of each year. At that time, day and night are balanced to nearly 12 hours each all over the world and the earth’s axis of rotation is perpendicular to the line connecting the centers of the earth and the sun. All of us who love gardening anticipate this event and hope that the phrase “Spring on Cape Cod” is not an oxymoron this year. Anticipation for this Spring is long awaited as we have just experienced one of the severest winters on record. As I write this the evidence of that sad fact are the large drifts of snow I am still seeing on my deck. Everywhere we go the piles of dirty snow in parking lots and along road ways have one wondering how an early crocus or snow drop could possible poke through these crusted layers. Hopefully it won’t be too long before forsythia, cherry trees and other early Spring shrubs and trees will reward our patience.
Three years ago the United States Department of Agriculture ( USDA ) published their revised Plant Hardiness Zones. Zone maps are tools that show where various permanent landscape plants can adapt. All horticultural material is classified according to its hardiness. Hardiness refers to a plant’s ability to tolerate temperature. The USDA Plant Hardiness Zone map divides the United States into zones according to the average minimum cold temperature. Plant material should indicate which zones it should be able to survive the average maximum and minimum air temperature. If you want a shrub, perennial, or tree to survive and grow year after year, the plant must tolerate year-round conditions in your area, such as the lowest and highest temperatures and the amount and distribution of rainfall. Here on the Cape we went from zone 6b to 7a which basically means we can “try” to plant a broader palette of regionally recommended plants with caution. When it comes to plant hardiness ratings and zone maps remember: they are general guidelines, not rules. There are any number of environmental circumstances that may result in different micro-climate growing conditions in your landscape and the intimate knowledge of those conditions results in successful gardening. The best rule of thumb is to be aware of your “ecological zone” and notice what thrives here on the Cape by careful observance of natural areas and long established gardens.
In addition to these guidelines one must remember to take into account our frost free period. Each winter, on average,our risk of frost is from October 17 through May 4. Almost certainly, however, we will receive frost from October 31 through April 15. We are almost guaranteed that we will not get frost from May 23 through October 2. The frost-free growing season is around 166 days. My wisdom has always looked to the last full moon in May and know that we are safe after that occurrence. The Full Flower Moon of May will occur on the 3rd which is very early in the month, so I would advise waiting until the 15th or later.
Enough science! Here are some practical tips for plant selection during March:
Some Plants That Can Take a Chill:
Bulbs: Crocuses ,Daffodils, Dwarf Iris, Grape Hyacinths, Hyacinths, Ranunculus, Tulips
Annuals: African daisies, Marguerite daisies Nemesias, Osteospermums, Diascia.
Perennials: Adonis, Barrenworts ,Bergenias ,Corydalsis, English Daisies, Hellebores, Pansies, Primroses, Virginia Bluebelss.
Tips For Acclimating Your Plants:
Plant spring containers when nighttime temperatures are consistently above freezing or just dipping down to about 30°F.
Cold temperatures and excessive sun can damage plants that haven’t been hardened off properly.
To harden off plants, keep them outside in a protected, partially shaded area for a few days, exposing them gradually to more sun and cooler temperatures.
Protect plants when a light frost threatens by covering them with an old sheet or blanket.
Move pots to a sheltered location if a severe frost is expected.

Spring Blossom Eye Candy
On a recent visit to Mahoney’s Garden Center in Falmouth I took the opportunity to add some cheer and color to a typically gray Cape Cod day. Nothing beats the blues better than feasting our eyes on the early harbingers of Spring especially pansies with their smiling faces and bright hues. After the routine chores of Spring cleanup consider placing a few containers filled with early blooms around your yard. Good strategic spots might be near the front door, on a deck, in flower boxes and in beds seen from your windows. Adding these small touches will certainly give you pleasure and herald the arrival of Spring on the 20th. Happy Gardening.
Please mark your calendar for Saturday, April 25th at 1:00 PM. I will be giving my annual Keynote presentation at the Centerville Public Library. This year the topic will be Backyard Escapes_ Ideas for Designing your Outdoor Room. Hope to see you there.
