The Crocus are Here! The Crocus are Here!   


Greetings!

 

Veronica with pruned willow branchesI spotted the first crocuses of the year about a week ago in downtown Des Moines, surrounded by pavement on a south-facing slope. But now my east-facing slope farther north in Ames is starting to bloom with its own cheering spots of bright yellow.
  Granted, when I spotted them two days ago, they looked as cold and wet as the gardener standing before them. But they're out there.
  And, hey, so am I! There's raking and pruning to be done, so I've gotten started with just a little. This weekend, I hope to spend an hour or two out there.

Happy Early, Wet, Cold, Spring Gardening!

Enjoy Potted Bulbs Now

If you've been lucky enough to enjoy some pots of daffodils, tulips, or other bulbs in bloom in pots right now, savor every moment. These plants have undergone a special process--forcing--that ruins them for planting out in the garden for more blooms in the future. Enjoy for a couple of weeks indoors. Then, when they flowers have faded, simply pitch.

More About Mulch 

   

You know you're living in a garden-nutters neighborhood when you promise your neighbor a cubic yard of mulch in exchange for doggy sitting your pooch.

  That's just what I did with Martha next door. But she and I value mulch for all the right reasons--it's such a great labor saver and makes our gardens look healthier and neater.

Mulch suppresses weeds.

Mulch conserves moisture.

Mulch prevents disease pathogens from splashing onto the lower parts of plants during watering and rain.

  I like to use grass clippings in my veggie garden and any kind of dark wood bark or chip mulch in my flower and other beds. I especially like double-shredded mulch, when I can find it, because it's small and easy to use around plants. Because I use so much mulch, I usually buy it more cheaply in bulk from a landscaper and have it delivered on my driveway.

  Warning: Do not use freshly chipped wood from your yard, tree services, or the city around most plantings. It robs the plants of critical nitrogen and they'll be stunted. The mulch has to sit around at least for a year first. (The stuff sold by professional landscapers and in bags at garden centers has already been aged.)

Garden Quote

 

"Spring is not the best of seasons.

Cold and flu are two good reasons;

wind and rain and other sorrow,

warm today and cold tomorrow.

Whoever said Spring was romantic?

The word that best applies is frantic!"

Click here for a month-by-month listing of "What to Plant When in Iowa."
 
Click here for a "Lawn Care Schedule for Iowa."

Take advantage of nice days to get out in your yard and pick up trash and sticks, inspect for winter damage, and just generally check out the state of your garden.

If perennials are sending up a little fresh growth, rake leaves out of flower beds and cut back any perennials left standing. Toss the old stuff in the compost heap. (Please tell me you have one, right?)
 
Edge beds, walks, and drives as desired.
 
Time to prune most large trees, small trees, evergreens, and shrubs. Hold off on pruning roses until they send out more growth.

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 there is little wind and temperatures are in the 40s.

The bright yellow forsythia will be blooming soon. When it does, that means its time to sprinkle any preemergent herbicide (kills weed seeds, such as Preen) on flower beds, if you choose to use it. It's also the time to apply a preemergent to your lawns. Or save time with a weed and feed combo!

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 last fall and the blade sharpened, do it yourself now or take it in before the spring rush.
