IPM: Cultural Control

caterpillar-and-leaf-damage_blkforest_20090729_lah_7823The best way to ward off insect and disease problems is to grow a healthy plant. Just as a wolf pack will target the weakest member of a herd, insects seem to zero in on a plant that is under stress. Good gardening practices—choosing the right plant for the spot, soil preparation, proper planting, feeding, watering, mulching, and the like, all go a long way to keep our gardens free of damaging pests.

But cultural control goes further than just having a green thumb. Sometimes our yards are invaded by insects no matter how good a gardener we are. In that case, it pays to know the enemy.

Birding with Children

winter-bird-count_fcnc_lah_6101My granddaughter, Willow, is only a month old, so it’s a bit too soon to be buying her binos and a field guide. Still, I’m looking forward to our first adventures outside, watching her joy as she discovers grass and flowers and ladybugs and, yes, birds. I hope she’ll be as fascinated with God’s creation as I am.

Since I hope to create a budding birder, I want to make sure I go about this in the right way. You can’t force a kid to love nature. So I’m already reading articles and talking to birding parents and grandparents about what works and what I should avoid.

Hail Survivors

centranthus-helianthemum-penstemon-trio-003Colorado isn’t an easy place to garden. Drought, late frosts and early snow storms, soils of sand and/or clay… to grow anything here, you have to be stubborn—and so do your plants. Our recent storms were so destructive, I thought I’d post something about how you can avoid a lot of hail damage in the first place. At least for ornamental landscapes, the key to surviving hail is plant selection.

A tour of the garden after a major hail storm will reveal some plants that are totally destroyed while others have nary a bruised leaf. What makes some plants hail-resistant?

After the Storm

[This article, by Joan Nusbaum and I, originally appeared in the Colorado Springs Gazette in 2005. I have edited it to make it even more applicable after last week’s storms!]

m5auwe-golfballhail67-c-gazetteLast week, our part of the world was hit by a horrific hail storm. Drifts (if you can call them that) measured four feet high. Houses, cars, and, of course, gardens were ruined by hailstones the size of golf balls (as this photo by Pam Woodward proves). It’s quite shocking to watch from your window and see thousands of hail stones plummeting your favorite garden. Do not despair—the plants may recover! Hail usually does not damage the root system. Here are some things you might do to help your plants survive and even thrive:

Lakewold Gardens Estate

lakewoldgardens-wa_lah_0694It had been raining all week, quite normal for western Washington in late May. We were near Seattle, visiting our brand new granddaughter (our first) and her parents. But then, unexpectedly, the constant drizzle turned into blazing sunshine and dazzling blue skies!  Being a gardener, I immediately looked for the closest public garden to visit.

In this case, Pete and I took an afternoon off to spend some time at Lakewold Gardens Estate, just off I-5 in Tacoma. Once the home of Mr. and Mrs. Corydon Wagner, the estate is now owned by a non-profit group specifically dedicated to preserving the gorgeous plantings and lovely house. The property fronts Gravelly Lake and, weather permitting, provides spectacular views of Mt. Rainier.

Eggplant Sex

solanum-melongena-gretel_eggplant_dbg_lah_7076

Girl eggplants? Boy eggplants? Does one taste better than the other? And what does all this have to do with plant sex?

In researching  my recent post on eggplant, I discovered a bunch of discussion about “male” vs. “female” eggplants. We’re talking about the fruit—the eggplants that we eat—not the individual plants on which the eggplants grew.

From a botanical point of view, this whole debate is nonsense. Let me explain:

My Favorite Eggplants

eggplant_dbg-co_lah_9256Eggplant Parmigiana, Moussaka, Moroccan Eggplant Salad, Baba Ganoush… there are plenty of delicious ways to eat eggplant. Growing it in Colorado is a whole different story. A native of warm and humid southeast Asia, it takes a bit of persuasion to convince this tomato family member to thrive in our cool, dry climate.

As Colorado gardeners, we have all sorts of tricks to modify the microclimate around our plants and extend a too-short growing season. Cloches, cold frames, copious use of plastic and accessories such as Wall ‘ O Water are all helpful. However, choosing the right varieties can mean the difference between crop failure and Ratatouille. (For more on how to grow eggplant, see the CSU Fact Sheet on “Peppers and Eggplants.”)

How to Help a Newbie

birders_clearspringsswa-co_20100306_lah_9330“I’m interested in learning how to watch birds. How can I get started?”

The question was music to my ears. Who doesn’t love to share their passion with someone else? It wasn’t so long ago that I was a new birder, trying to juggle a crummy pair of old binoculars with a mysterious field guide, all while trying (unsuccessfully) to keep an eye on the bird I was trying to identify. I’ve come a ways since those early days and even though I still have much to learn, I’m eager to pass on my limited birding skills.
