It's seed startin' time!

Start yer ‘maters!

By Amy McDowell

The green flag is out, garden fans. Seed starting season is upon us here in central Iowa. At the finish line we’re not greeted by the checkered flag, but the red ripe tomato. Is your adrenaline pumping? I hope so, because you are in for another gorgeous garden season and one fantastic ride.

Gather the tools you’ll need and let’s get growing. Any clean container with drainage holes in the bottom will work. Choose a quality seed starting mix and moisten it with water until it’s spongy. Fill the containers with the mix and tap it down lightly. Now sow the seeds and sprinkle a little more seed starting mix over the top. Don’t forget to label your pots.

Cover the pots with clear plastic to keep the soil moist until the seeds germinate. After they germinate, the covers can be removed for good, but you’ll have to keep a closer eye on the soil to make sure it doesn’t get too dry.

Most seeds will germinate better if you can provide bottom heat. If you can, set your pots on the top of your warm refrigerator or some other warm spot.

As soon as the seeds sprout, move the pots to a bright window or under grow lights. Bright light is important at this stage so the plants don’t get too tall and spindly. The window location may get cooler at night, so you might need to move the plants out of the window at night and back into the bright light during the day. If you use grow lights, keep the lights suspended just above the growing plants, and use a timer so the lights are on for at least 12 hours a day.

New seedlings are tender; don’t let them get too dry or keep them too wet, because they can collapse in either extreme.

One last note and then you’re off and racing. If you have the space in your garden, think about growing a little extra for the Plant A Row for the Hungry program. Because of the recession, the demand for hunger assistance has skyrocketed in recent years, and sometimes food pantries are forced to turn people away because they don’t have enough resources to assist everyone.

The DMARC Food Pantry will take garden produce, but you’ve got to drop it off weekdays between 8 a.m. and 4:30 p.m. at 3816 36^th Street in Des Moines. Maybe you can even organize a Plant A Row group in your neighborhood or church. Whatever you do, gear up and get ready for a great season.

Direct-sow annual flowers in your garden

Flowers from Seed

By Amy McDowell

I turned my nose up at zinnias for years. I thought they looked gaudy—bright pink, orange, and red pompoms and coarse foliage dusty with mildew. One year, however, Grandpa McDowell sprinkled a package of zinnia seeds into his garden. A magnificent swarm of butterflies hovered over his garden when we visited on the Fourth of July, and that vision has forever changed my opinion of zinnias.

Raid the seed rack at your local garden center, and you can broaden the spectrum of delight in your garden. There are all kinds of annuals that are not offered in plant packs, but are simple to grow from seed. Annual flowers will not only give your perennial garden continuous color, but they can give it a full, gushing-with-blooms cottage garden look.

Flax, cosmos, and nigella (Love in a Mist) are delicate looking, and you can sprinkle the seed around your perennials to create drifts of color from one end of the bed to the other. Flax creates a wispy hint of color. Blue is the most common, but it also comes in bold yellow and pink. Cosmos blooms are a little more defined in the garden; they come in pink, red, white, and newer yellow and orange varieties. Nigella has feathery foliage and pastel blooms in blue and pink.

Datura and cleome are a couple of giant annual flowers that you can count on reseeding in your garden year after year. Datura have huge five to eight-inch trumpet blooms in white, lavender, and yellow. The standard white ones are sweet smelling, kind of like Fruit Loops. Cleome, sometimes called spider flower, comes in pink, lavender, and white.

Four O’Clocks open their blooms in the middle of the afternoon, hence their name. They come in terrific pink and yellow colors, and form a rounded, knee-high mound. They will also reseed and create large drifts in your garden if you’ll let them.

If you have a hot spot that just bakes in the sun, try poking a few nasturtium seeds into the ground. The first time I grew nasturtium, I planted them in a two-foot square patch between the garage, the driveway, and a sidewalk. It was a southern exposure that was far from the garden hose, so they got little care, but they thrived.

All of these annual flowers can be sown directly into the garden in early May. Annual flowers pollinated by bees, birds, and butterflies in the garden will often lose their boldest colors as they reseed over the years. When the colors start to look watered down, some gardeners hoe the seedlings under in the spring and plant new seed. It’s always delightful to try something new in the garden, and seeds are an inexpensive and fun way to experiment.

An African Violet Affair

African Violets

By Amy McDowell

After a couple of weeks of frantic lunacy-driven Ebay bidding, packages of African Violet leaves began arriving on my doorstep. Each leaf was packaged carefully in a plastic bag with a label bearing its name. I lined them up, each in an empty plastic 6-ounce Sunny D bottle with the violet’s name taped on the side. I filled the bottles with water and when I was finished, four dozen bottles sat under fluorescent shop lights.

In a few weeks, tiny new plants grew on each leaf and delicate white roots filled the makeshift vases. In one marathon potting session, I settled each little plant into a 4-inch plastic pot filled with lightweight, soilless potting mix. I peeled the labels from the plastic bottles and stuck them to the pots. As I struggled to find space for all of them, at last I recognized my folly.

African Violets are ideal houseplants. Thousands of varieties offer plant lovers a smorgasbord of colors, styles and sizes. They are easy to care for, thriving and blooming in ordinary household conditions. Their delicate nodding blooms arise from the fuzzy foliage before unfurling in rich purple or red or pastels of every hue.

Grow African Violets in bright light from a north- or east-facing window or under fluorescent lights. Water from the bottom by filling the saucer with water, letting the soil soak it up, and dumping out any leftover after a half an hour. Fertilize as often as you want by adding one-quarter teaspoon of 20-20-20 or 15-30-15 to a gallon of water. Mine bloom well even with infrequent fertilization.

Their fuzzy leaves protect African Violets from most insects, but foliar nematodes are a killer. The center of the plant starts to look like a tiny head of cauliflower as the newest leaves are shrunken, contorted and white. Nothing can be done to save them; throw the plant and the pot away. Be careful not to aid the spread of the nematodes by letting the plants touch. Thoroughly wash your hands and any tools, including the watering can, that have come in contact with an infected plant.

Hedges to keep the neighbors out

Thorny rugosa roses can fortify garden boundaries

By Amy McDowell

It was an otherwise quiet evening at the garden center. The after-work crowd had slowed as people headed home for dinner. The summer sun far in the western sky cast long shadows across the parking lot. I was monkeying with the bird feeder display when the bell on the door jangled, and I turned to greet a well-dressed woman in a tailored brown business suit. She approached with a frown.

“Do you sell poison ivy plants?” she asked.

“Poison ivy?” Surely I had heard her wrong. She must’ve said Boston ivy.

“Yes, poison ivy,” she said. “Can I buy poison ivy plants?”

I lifted my eyebrows and mentally reminded myself how stupid I look standing with my mouth hanging open. “Um, no, we don’t sell poison ivy,” I said, studying her brown eyes closely for signs of insanity.

“Oh.” Her shoulders fell a little. “Then how about seeds? Do you sell poison ivy seeds?”

“Uh, no.” I said, and finally caved in to my bafflement and asked why she wanted to grow poison ivy.

“It’s my neighbors,” she said. “They’re always cutting through my back yard. It’s even fenced and they climb right over!” She waved her flawless painted nails in the air and her diamond ring glittered under the fluorescent lights. “I yell at them and they act like they don’t understand English,” she said, “but I know they’d understand the international language of ITCH.”

I breathed a sigh of relief. She was not a lunatic, just bonkers and sick of being trespassed. When I couldn’t help her, she left the store exasperated.

I’ve since come up with the perfect remedy… rugosa roses. These fast-growing beauties are covered with barbaric thorns. The stiff stems are ferocious from ground to tip. Rugosas form a rounded thicket four to six feet tall and wide. Planted three or four feet apart, they make an impenetrable hedge.

Better yet, the fragrant fuschia, pink or white blooms in the summer are followed by red or orange rose hips in the fall. In Latin, ‘rugosa’ means ‘wrinkled,’ a name fitting the crinkled dark green foliage. Fall color is usually short lived and yellow, but some rugosas turn orange or red. Rugosas are among the most disease free of all roses, so they don’t need any pesticide sprays. Annual deadwood pruning in spring is the only care they require.

Rugosas prefer well-drained soil in full sun or light shade. Hardy from zones 2-7, rugosas are wintertime tough. They’ve “been seen 100 miles from the Arctic Circle in Siberia where the temperature regularly falls to –50 degrees Fahrenheit,” writes woody plantsman Michael Dirr in his Manual of Woody Landscape Plants, 1990, Stipes Publishing Co.

Because of their vigor and easy care, rugosas are used in hybridization programs for new roses.

Next time someone asks me about poison ivy to keep interlopers from the yard, I’ll be ready with a suggestion. The wicked prickly thorns of beautiful rugosa roses will keep even the most brazen intruders at bay.
