Happy Spring! Get Ready for the Hummingbirds!

Tax season is here! Even if you aren’t getting money back this year, tax day can still bring you joy.

This is the time of year that hummingbirds migrate north. Hummingbirds send out “scouts” to look for places where food is readily available and they are usually the first to arrive. If you’re wondering when the best time to put feeders out and attract scouts, let tax day, April 15th, be your reminder.

If you are interested in bringing hummingbirds to your yard, here are a few other tips, including an easy recipe for hummingbird food:

  • Hummingbirds have a great memory and will likely visit the same area from year to year.
  • Hummingbirds are territorial. Having multiple feeders in various locations can help to bring more of them to your yard.
  • Hummingbirds love red, so consider a red feeder or putting the feeder near some red plants such as cardinal flowers.
  • Rather than using the red hummingbird food sold in stores, try making the food yourself. It is simple to make and better for the hummingbirds. (See Recipe Below)
  • Consider hanging ant motes along with your feeders so that ants don’t get into the hummingbird food.
  • Hummingbird food can last about 2 weeks in the refrigerator. Before adding it to the feeder, it should be closer to room temperature. Thus, if you are taking it directly from the refrigerator, it is advisable to let it warm up before pouring it into the feeders.
  • Hummingbird feeders should be changed every 3-5 days. The sunnier it is, the quicker the feeder should be changed so the food doesn’t spoil.

Hummingbird Food Recipe:

  • One cup sugar to 4 cups of water.
  • Bring the sugar and water to a boil for 2 minutes.
  • Let it cool before putting it away or putting it into a feeder.

The Ralph Archer Woodland Garden at Whitehall Estate Gardens

The Ralph Archer Woodland Garden at Whitehall has been a Master Gardener project for many years.  The garden contains the largest regional collection of ferns thanks to long time Master Gardener, Ralph Archer.
On Saturday, June 24, Carolyn Waters, who has a masters degree in environmental education, led two tours through the garden to show how the garden is habitat for flora, fauna, and environmental processes beyond ferns. Carolyn pointed out trees of various ages and sizes which provide layers attractive to birds. Carolyn, who lives on the property, has seen Baltimore orioles, scarlet tanagers, golden crowned kinglets, nuthatches, and many varieties of wrens in this garden.
She demonstrated forest succession by identifying trees that had come onto the property first after the site was cleared, and the trees that followed such as several species of oaks and hickories. In recent years, those trees were intentionally planted to speed up the evolution to a later succession woodland.
Carolyn explained how a naturalized garden like Whitehall's woodland garden expands biodiversity, giving a home to both native and exotic, but not invasive plants.  Retention of dead trees, decaying logs, wood mulch, and duff gives habitat for both animals and plants.
Future plans include diversion and retention of storm runoff and a water feature which collects rain water that will slowly drain into a small bog already in existence.
During the tour, Whitehall's new stone benches, collected from a local farm on the Ohio River, were used by the tour visitors and by one of Whitehall's resident cats, Grady.

Insect Hotel at the Louisville Nature Center

We have bee action at the Louisville Nature Center Insect Hotel in Louisville, Kentucky!  The queen in the picture is laying eggs in her nest.

Other bees were in various stages of egg laying, depositing pollen and creating mud partitions.  I did not have a chance to see any of them outside of their logs so I was unable to make a positive ID by just peering at them down the dark hole with a flashlight.  With 4000 native bee species in North America, it would be difficult to even venture a guess without getting a good look.  These native bees were here long before settlers brought honey bees from Europe.

The gardens at the Louisville Nature Center provide pollen and nectar and the bees, messy little pollinators that they are, give back by cross-pollinating flower gardens, vegetable gardens, trees and orchards, both at LNC and in the surrounding community.

The hotel was established by a Boy Scout troop a few years ago and has successfully provided homes for insects and native bees.  Weather elements have caused some settling of the materials, so a renovation is in order.  This will occur in the Fall, while the "guests" are asleep.  My goal is to create as much native bee habitat as possible.

Queen Bee

Materials I am gathering for the rehab include: bark, pine needles, pine cones, and logs. I am currently cutting logs and drilling the preferred-sized holes for solitary bees to nest in. Add a few canes to the collection and I'll be ready to update the hotel habitat.

Queen Bee nests in logs

Blue Orchard Mason Bees and Alfalfa Leafcutter Bees, among many others, are fascinating to watch and can be easily assisted by providing simple habitat. They are gentle bees and rarely sting (unless squished, of course). Did you know that you can harvest their cocoons, store them over winter, and then hatch them in the Spring? This is definitely on my "To Do" list!

Mason Bees plug their nests with mud

As I explore their world to learn more, I will be writing about the different types of bees, their nesting habits, cocoon harvesting and suggestions for providing homes and other necessary supplies, such as flowers and mud. Keep your eyes peeled for native bees and you will begin to see their diversity.

I welcome you to journey along with me as I gather and share information about these gentle, vital creatures. Happy bee watching!

A Collaboration at the Louisville Home, Garden and Remodeling Show 2017

The Jefferson County Master Gardener Association shared in a collaborative effort with Urban Forestry and Louisville Grows at the Louisville Home, Garden, and Remodeling Show at the KY Expo Center on March 3 – 5, 2017. Urban Forestry had 4000 red oak and black oak bare root saplings that we wrapped, bagged and gave away during the Home Show. It was a huge success.

There were 502 people who stopped at our booth for information about trees and tree give away events including JCMGA Arbor Day Tree Give Away on Saturday, April 22. Flyers were given out about Gardenaganza on Sunday, April 30. Information was shared about soil testing, vegetable and flower gardening and how to attract pollinators.

The Garden Stage presentations were very well received. A huge thank you to our JCMGs, Julia Wall and June Sandercock, and Whitney Sewell, Director of Urban Agriculture, from Louisville Grows, who presented at the Garden Stage at the Home Show. It was an awesome success in building community awareness of the Jefferson County Master Gardeners, the Jefferson County Extension Service as well as Urban Forestry and Louisville Grows while helping make a difference in the tree canopy in Jefferson County.
