Nature Almanac for March 2021

Bumble Bee and Grape Hyacinth
Bumble Bee and Grape Hyacinth in my garden.

Here in Philadelphia…

The snow is still on the ground. It’s melting quickly. The birds are singing. It has been a long, shelter-in-place kind of winter. And I am oh so ready to work in my garden and walk the trails of nearby parks.

But if last fall was any sign of how crowded the parks will become, I will work on my backyard habitat garden this spring. I started replanting pollinator plants last year.

I’ll be starting borage seeds this weekend. Borage is a herb that bees go crazy for. I bought a packet of borage seeds from Botanical Interest this winter. I think two or three plants in my small backyard garden will draw in the pollinators, the bees and flies which will pollinate my fruits and tomato plants. You can buy borage seeds here.

My plans include growing more food in my backyard. I haven’t spoken about it but last year I had surprise carpal tunnel syndrome hand surgery.  My hand is still recovering. I stopped writing a book I was working. I’ll return to writing it this summer. But I have made headway on another title.

I am making progress on my book on butterfly gardening. I am aiming for an April release. Stay tuned.

Making a Bloom Calendar

Henry David Thoreau kept a nature journal. He was famous in his town for knowing the sequence of blooming of native flowers. This type of calendar is a ‘bloom calender’. Every Wednesday in March, I’ll post a list of what is blooming in my backyard habitat garden. It will keep me aware of the unfolding of spring close to home.

Did You Know?

The blossoms of many early spring flowers are white or yellow? The primary pollinators of early flowers are flies who lack color vision. The white and yellow blossoms reflect plenty of light to attract the flies. Read my post on the topic.
