Keeping Mosquitoes at Bay

mosquitoLast month we learned that the so-called mosquito repellent plants don’t actually keep our yards pest free. Does that mean we have to suffer annoying, itchy welts? Thankfully, there are alternatives. We start by preventing mosquitoes from breeding.

Most of us know that mosquitoes lay their eggs in water. The eggs hatch into aquatic larvae. In as little as three day (depending on the temperature), those larvae become flying adults. The males leave us alone, but the females suck up a gut full of nutrient-rich blood to support egg-laying. And often, that blood comes from us.

CFO for Mother’s Day!

White Pelicans_LakeMeredith-CO_LAH_6144Some moms receive roses for Mother’s Day. Others are given chocolates, dinners out, or photos of their adoring children. While I did enjoy dinner in a restaurant on Mother’s Day, I wasn’t dining with my family. Rather, I spent the day—actually five days over a long weekend—attending the annual Colorado Field Ornithologists (CFO) convention, held this year in Lamar (almost to Kansas and Oklahoma), Colorado.

My family knows what makes me smile.

Fabulous Fernbush

Chamaebatiania millefolium - Fernbush_XG_20090720_LAH_7320From a distance, a blooming fernbush (Chamaebatiaria millefolium)  resembles a lovely white lilac bush, but no lilac would be in bloom at this time of year. Growing to seven feet high and wide, these shapely shrubs are covered in upright sprays of showy white flowers from June through August. Individual blossoms are reminiscent of single roses, and attract bees and butterflies. Come autumn, the flowers are replaced by russet seed heads.

A closer inspection reveals reddish peeling bark and the aromatic, finely dissected leaves that give Fernbush its common name. Even in our cold climate, these leaves stay on the bush for most of the year; branches are bare for a mere three to four months each winter. Fall foliage is an attractive copper color.

Except…

We’re familiar with these facts:

  • Brown Pelican_DingDarlingNWR-FL_LAH_6701Brown Pelicans are saltwater birds, sticking to the coasts.
  • It’s only the male bird that sings.
  • Birds that migrate fly north in the spring and south in the fall.
  • Great Blue Herons eat aquatic insects, crustaceans, amphibians (such as frogs) and fish.
  • Males have the ornate feathers, while females tend to be drab and camouflaged.

We think we know. We think we understand. We’ve observed, conducted studies, collected facts. We think we have it right. And then Mother Nature confounds us.

Beyond Spring

Malus 'Branzam' Brandywine_Crabapple_DBG_LAH_5147Most landscapes look terrific in May and June. The leaves are fresh and new. From pink crabapples to purple lilacs, it seems as if everything is in bloom. The contrast with the lifeless browns and grays of winter is enough to send you cavorting across the  glowing, emerald green lawn.

It’s tempting—irresistible, really—to rush to the local garden center and buy everything with flowers on it. I’ve been subjected to Facebook photos of flowers since March (I have a lot of friends in California), and finally it’s our turn!

Garden Advice: Companion Planting

carrots-tomatoes-401Do carrots really love tomatoes? Do beans and onions hate one another? The internet (and my bookshelf) is full of anecdotal advice about which crops we should plant together, and which ones we should not.

There’s a well-known book that’s been around for ages called Carrots Love Tomatoes: Secrets of Companion Planting for Successful Gardening, by Louise Riotte. It offers page after page of “facts” about companion planting. That sounds really helpful, and I was ready to try it all, but unfortunately, when I dug in online, I discovered that there is very little science behind the advice.

Planting a Tree

Improper staking_LAH_5226How do you plant a new tree? Most people know to dig a hole “twice as wide and deep as the root ball” (according to the label I found hanging from the branches), then stick in the tree, making sure the roots are well buried. Amend the backfill with plenty of compost, pile it over the roots and tamp it down firmly. Finally, securely stake the thin trunk so it won’t wiggle in the wind. Right?

Wrong!

This advice was being questioned as far back as 1980, but it is still widely practiced, much to the detriment of the poor plants.

Bird-a-saurs

A shallow, warm sea reflects sunlight in the distance. Here on the shore, a flat beach is backed by low hills. The hillsides are home to dozens of large, circular depressions approximately six feet across. These are nests, and the assemblage is a rookery.

Some nests still contain eggs, others have young in residence. The nestlings have been here a while, hanging out with the their parents, who in turn provide both food and protection. (more…)
