Ladybug, Ladybug

ladybug-on-fernleaf-dbg-19sept05-lah-193The quintessential “good bug,” ladybugs (aka ladybird beetles) are the poster child of the beetle world. Everyone knows that ladybugs eat aphids and other “bad bugs” (especially scale insects) and should be welcomed in the garden.

Actually, not all ladybug species are red. Some species are orange, yellow, white, black, brown, or gray. And not all ladybug species eat aphids, although most do. Some are even agricultural pests, such as the infamous Mexican Bean Beetle. Still, most ladybugs are red, and they eat vast numbers of aphids, as well as scales, mealy bugs, leaf hoppers, mites and other soft-bodied insects and their eggs.

IPM: Physical Barriers

apples_browns-tacoma_20091016_lah_4005Let’s say you want to grow apples in your Colorado garden—a perfectly reasonable option for this area. You’ve selected a variety that’s resistant to fireblight (I discussed disease-resistant varieties in May), and your tree is thriving. In fact, after several years, it’s finally beginning to bear fruit. You pick your first juice, red apple, take a big bite, and… oh no! Yup, you find half a worm. Ewwww.

IPM: Resistant Varieties

dbg_lah_6794Is your garden being bugged? While 95% of all insects are either beneficial or benign, that last 5% can eat us out of house and home—or at least out of cabbage and broccoli. If insect invaders are on the attack, sometimes you just have to fight back.

Pests may be persistent, but we gardeners are not helpless. I like to remind myself that I am smarter than an aphid and more cunning than a flea beetle. When it comes down to a battle for the harvest, there are lots of tools at our disposal. As a master gardener, I was taught the principles of Integrated Pest Management, or IPM. Rather than just reaching for a spray can, this approach is multifaceted. There are many ways to outwit a weevil.

Planning Ahead

garden-dreams2

It’s the beginning of a new year, and time to dream about the upcoming growing season. Do you want to add some permanent plantings?  Are you imagining flower beds brimming with annuals? Will you be buying from catalogs? (Get that order in early before they run out of that must-have variety.)

With the Christmas decorations packed away for another year, I finally have time to take a deep breath, brew a cup of tea, and begin to think about spring. I start by making a list of topics, and then mark down what will need doing, and when.

flamingo-eaters-1Has your garden been assaulted by a plague of pink flamingos? Are your furrows full of gnomes? Maybe your problem is something as simple as a dreary winter landscape. Don’t despair, help is on the way. Even though traditional remedies may fail, extensive research has revealed a guaranteed solution to all of these garden woes.

Eggs!

pullet-eggs_lah_2165After a fox attack last spring, we’re down to only three aging hens and six five-month-old pullets. Instead of giving eggs to all our friends, I’ve had to buy them at the market. So this morning, after being out of town for the weekend, I walked out to the coop hoping to find an egg, or maybe two. Instead, there were close to a dozen!

Yup. A month ahead of schedule, our new pullets have become egg laying hens.

Powdery Mildew

powdery-mildew-on-pumpkin-dbg-19sept05-lah-572The huge zucchini leaf looked as if it had been dusted with flour. The man holding it was looking at me expectantly, waiting for my diagnosis. I was volunteering at our county’s Master Gardener helpdesk, providing free gardening advice to the general public. Sometimes we get stumped, but this time I immediately knew exactly what the problem was.

“Your zucchini plants have powdery mildew,” I told the man. “It’s pretty common around here, especially this late in the season.”

Grasshoppers

They’re chewing holes in my big, beautiful chard leaves, leaving tiny dark pellets of digested foliage to mark their conquests. They jump aside as I walk through the knee-high grass in our field. Until I moved to Colorado I had idea how plentiful grasshoppers are (we’re home to over a hundred different species!), or how much frustration they can cause a gardener.

There’s a Mouse in the House

Eew! What was that horrible smell? Even with chronic congestion associated with my being allergic to nearly everything, I could tell something had died. Following my nose, I wandered downstairs, then into the corner of the basement with the seldom-used utility sink. As I got closer, I realized the deep sink was completely full of dirty water  that lapped at the faucet and threatened to spill over the counter and onto the floor. I hastily ran upstairs to alert my handyman husband.

Mealybug Invasion

long-tailed-mealybug-c-david-cappaert-michigan-state-university-bugwoodorg-2With temperatures dipping into the low 20s and our first (finally!) snowfall, the bugs in our gardens are either dead or in hiding. But before we collapse into that comfy recliner with a garden book and a cup of tea, we need to take a good look at our houseplants. It might be winter outside, but indoors the bugs are having a field day.

At least they are at our house. I’m currently at war with some aggressive invaders. They’re about an eighth of an inch long, are covered with sticky, gooey, white fluff, and are wedged into the leaf axils of many of my favorite houseplants. Yup, my indoor garden has mealybugs. (more…)
