The Big Melt
 
Veronica at potting bench  creditGreetings!

I saw something astounding while driving along the street today. If I remember the name of it correctly, it's called "grass."
   Finally. Let the spring thaw begin!
   I've been a good Iowan long enough, noting how pretty the snow is, admiring the 6-foot (I'm not kidding) icicles by my front door, enjoying time reading by the fire, brightening my home with forced daffodils, being a cheerful trooper and going on brisk winter hikes. But good Lord I'm sick of it. I found myself on the drive today opening my car window to let in the delightfully warm, fresh air.
   It was 36 degrees.
   Utterly tragic.
   But we've got forecasts for highs in the 40s the next several days. Even as I write, I can hear the crash of giant ice floes, slipping from my roof and crashing onto the pavement below.
   It's a beautiful, beautiful sound.
 
Yours in warming trends,


Veronica Lorson Fowler

Ready for Radishes

red radishesCan you believe that if this snow actually melts on schedule, it will be time to plant radishes in just two weeks? (Click here for more info on growing.)
   Radishes are one of the first veggies you can put in the ground, as soon as it thaws and you can work it. It gives me such pleasure to plant and harvest something so early.
   Tip: Plant carrot seeds with the radishes. The radishes germinate quickly, marking where the carrots (which germinate slowly) were planted. After about a month, the radishes are ready for harvest. You can thin the carrots at the same time. They mature several weeks later.

Sweet!
One problem with planting radishes and other very fine seeds is that it's hard to disperse them. The result is that a week or two later you have a thick stand of seedlings. So you have to thin them heavily, wasting mucho seed. 
   Here's a great tip: Mix the seed with a tablespoon or two of granulated sugar. It helps you sow the seeds more evenly and farther apart. Then it dissolves harmlessly in the soil.

Must-Have Tool:
A Soil Thermometer


There's an old saying that Iowa farmers know that the soil has warmed up enough to plant corn when they drop their drawers and can sit on the ground comfortably.
Soil thermometer   Me, I like to be a little more scientific (not to mention modest) about it. A soil thermometer ($7 or $8 at a garden center or on-line) can be a cold-climate gardener's best friend.
   Most seeds (notably peas) are picky about the temperature of their soil, and especially during a weird year like this one, it can be hard to tell if the soil is warm enough. A soil thermometer can tell you in just a minute or two.

And the Winner Is...
So in the last newsletter, we asked you what the first flower of spring is. Robin Heinemann of Des Moines was the first to guess correctly: the snowdrop. It comes up right through patches of snow. (Readers Ron Warnet of Ackworth reported that two or three years ago, he had some blooming snowdrops newly bloomingon December 31!). Robin wins tickets for free admission to the Des Moines Botanical Center.
   I love snowdrops. They're bulbs, so plant them in fall in groupings of 10 or 15. Put them in a well-drained spot that gets enough sun to thaw early in spring so you can enjoy them absolutely as early as possible. Most years I spot the first one in late March. Totally cheers me up. In fact, more than once, it's made me so happy it's brought a tear to my eye. Such a plant geek, I am!
Where Do You Like to Buy Plants and Garden Supplies?

I'm putting together a list of my favorite Iowa places to shop for plants and garden supplies. We'll create a web page and post it on The Iowa Gardener web site.
   But I'm just one person. If any of you have any nifty places you'd like to share, shoot me an email! The more the better!

Garden To-Do List
Click here for a printable version of these garden tasks.
 
Start seeds indoors now of perennials, onions, and slower-growing annuals that you should start 10-12 weeks before the last average frost date (in Iowa, that's in mid-May.) These include snapdragons, annual salvias, and impatiens.
 
The last week of March or first week of April, start seeds indoors of annuals that you should start 6-8 weeks before the last average frost date. These include marigolds, globe amaranth, sweet alyssum, and flowering tobacco.
 
Once you can easily work the soil outside, plant directly in the ground seeds of fast-germinating cool-season vegetables, such as radishes, spinaches, and lettuces.
 
In southern Iowa, plant bareroot trees, shrubs, and roses at the end of the month, once you can work the soil easily.

Prevent diseases and insects on fruit trees by spraying with horticultural oil, also called dormant oil. Do so when temperatures are in the 40s.

  Start to prune most deciduous trees and shrubs now, while they're dormant.

Stock up! Work off your spring fever to buy now pots, potting soil, seeds and seed-starting supplies, tools, soil amendments, fertilizers, etc. You'll save trips to the garden center during the spring rush. And get out there and clean up and organize your garage or shed, wash up pots, etc. so you're ready at the starting gate.

How's your mower? If you didn't get it tuned up ast fall and the blade sharpened, do it yourself now or take it in before the spring rush.

Same for any shears or other sharp cutting or slicing objects, including spades and hoes. If you haven't already, invest a few bucks in a sharpening stone. It makes all the difference. Click here to learn how. It's easy after you do it once or twice.
