Inspiration and Impact:

In January, Arlington and Alexandria VA Cooperative Extension Master Gardeners and 4-H Youth Leaders and agents trained Arlington County staff on some Junior Master Gardener projects. Tomorrow staff at Westover Library are hosting Kids in the Garden – a program inspired by what they learned at the Cooperative Extension training.
The kids will plant some seeds to take home – and see how they grow…

Look out for more youth gardening activities this season at the libraries and in Arlington County Dept of Recreation after-school programs.

And let’s grow these inspirational and successful VA Cooperative Extension training programs!

Plant spring-flowering bulbs over the holidays!

You can plant spring-flowering bulbs outdoors over the holidays.
Here’s some tips from Master Gardener,  Christa Watters: 

Procrastinators rejoice! Though those of us who grew up in colder climes may think it’s too late to plant our bulbs for spring bloom, it’s really not – at least not for all bulbs. Tulips, for example, can rot in the ground in our heavy Virginia soil during warm, wet falls. Some sources say that waiting until about first frost is better for tulip bulbs, which like colder climates. Plus, it gives the squirrels less time to dig them up before frost hardens the ground. Still, you need to get them in before the ground really freezes.

So November, and sometimes even early December is still fine. It’s also fine for planting daffodils and narcissus bulbs, hyacinths, crocuses, even grape hyacinths.

Be generous – color massing is the most effective way to create an impressive and heart-lifting display next spring. So cluster the bulbs in drifts that complement the rest of your borders or beds.

2 - Glossy Tulip Perfection

Cluster complementary colors in your borders for maximum effect.

In our area, most hybrid tulips don’t successfully come back in succeeding years, and should thus be treated like annuals. If you do leave them for a second year, choose Darwin varieties, some authorities recommend. Alternatively, choose species tulips that generally perennialize better and naturalize well in rock garden clusters, as in this photo of Kaufmanniana tulips at the Simpson Waterwise Garden.

Daffodils and narcissi are much more reliable at coming back year after year and even multiplying in the ground. Choose some bulbs for their massing effect, yes. But also consider choosing some for their individual beauty, like these gracefully winged white and yellow Cyclamineus narcissi.

For fall crocus and colchicums, the fall-blooming relatives of our spring bulbs, it is, unfortunately too late this year, but while you peruse the catalogs, make a note on your calendar to order the bulbs in a timely manner next year. Spend some time this winter researching the best times for those . Here are a few photos of fall blooming bulbs to set you dreaming:
