Limiting Factors

2016-04-13 13.27.34

Spring has finally arrived here at 7,100 feet, and I’ve been feverishly planting—move the mulch, dig a hole, dump the perennial out of its  pot and stick it into the ground. Fill in any gaps with leftover dirt, replace the mulch. Rinse, repeat.

As I work around the lawn, adding flowers everywhere I can, I’ve noticed how abysmal my dirt is. Since we added compost, I assume that eventually it will qualify as soil, but right now I’m dealing with lumps of bentonite clay embedded in a deep layer of gritty, coarse sand. The clay was supposed to be seven feet down, but in the process of digging a basement, it got mixed  with the surface layers.

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.

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.

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.

Mosquito Repellant Plants? Caveat Emptor

mosquitoI sometimes wonder why God made mosquitoes. They’re so… annoying! No one enjoys getting bitten. It’s more than just the never-ending itch—they carry some very nasty diseases such as malaria, yellow fever, and chikungunya. Even here in the U.S. we’re at risk of West Nile, dengue, viral encephalitis, and now zika.

Lavendula - Lavender @DianeBrunjes-GlenEagle 22july05 LAH 003rMy Facebook feed is suddenly overflowing with lists of plants that supposedly repel mosquitoes. Just plant these flowers and herbs and your yard will be pest-free! Or, as one post on Pintrest claimed, “Plant a Mosquito Control container so you can sit and unwind in the evenings.” Unfortunately, anything that simple raises a red flag for me. Can controlling mosquitoes really be as easy as planting marigolds and lavender? It took some research to get past the hype, but I eventually found some scientific studies that look at this question.

A Colorado Gardener

PaintMinesCO_20100405_LAH_1277As a gardener, I’ve often dreamed of living someplace where plants actually want to grow. Colorado is definitely not that place. The weather is wacky, we’re short on water, and the soil dirt runs to extremes—we can either make pottery or fill a golf course bunker.

You might wonder how anyone could grow anything in such an inhospitable location, but there are definite advantages. As we look forward to another growing season, and I am looking forward to it, I want to focus on the positives. Here’s how an optimist views gardening in Colorado.

Auto-corrected Flowers

Heuchera_Coral Bells_DBG_LAH_1435A (long) while back I posted Heidi’s list of auto-corrected bird names. I thought it was pretty funny, partly because most bird names are not normal words. What’s a spell-checker supposed to do when confronted with names such as Willet, Phalarope, or Gallinule?

Being both a birder and a gardener, I began to wonder how Microsoft Word would treat some of the more unusual flower names. Typing a quick list was quite revealing! Then, as I went to retype everything in WordPress, I discovered that they don’t use the same dictionary. In a few instances, it had its own list of suggestions, making things even more interesting!
