Timing Peas

pea-vines-home-lahIt’s almost Saint Patrick’s Day, the traditional planting date for peas. Should you sow on March 17?

Not if you live along the Front Range! While St. Patty’s Day may work fine for New England, it’s probably the wrong day to plant for much of the country.

If you live in a warm climate (E.g., parts of California, Florida, and Arizona), you are far too late. Peas should be planted as a winter crop, so they can grow while the weather is cool and humidity is higher.

And if you live here in the Pikes Peak area, mid-March is much too early. Sure, peas planted now may survive and grow and produce a crop. But they may also rot in too-cold soil, waiting for temperatures at which they can germinate.

Are the Crocuses Up Yet?

crocus-dbg-lah-016This is the hardest time of the year for me. After growing up in California, I’m used to spring starting about now. I want to get growing now—not wait for two or three extra months! So today, in defiance of Colorado’s climate, I’m going to give you some crocus growing tips. Take that, winter!

While the snow has mostly melted, even the recent warm temperatures haven’t been enough to thaw my soil. The perennial bed looks exactly how it did a month ago—brown and lifeless. However, by blogging friend Carey (at Carey Moonbeam), across town and a smidgen lower in elevation than I am, reports she has blooming crocuses in her yard!

Berries for the Birds

american-robin-in-russian-hawthorn_xg_20091215_lah_5562xHow would you like to have a flock of robins outside your window? How about other thrushes, waxwings, sparrows, towhees, or vireos? Want to add Western Tanager to your yard list?

Along with finches, grosbeaks, thrushes, some warblers, Northern Mockingbird, Townsend’s Solitaire, chickadees, nuthatches, swallows, woodpeckers, pigeons/doves, jays, and even hummingbirds (who drink the juice), all these birds eat berries at some point.*

Planting shrubs and trees that produce berries is a great way to attract more species of birds. Even better, plant several kinds of berries, since each bird species has its favorites.

Beautiful Edibles

733-lunch-1I love salads. Wash and tear some crisp, homegrown lettuce. Add a few sprouts, some mizuna leaves (mizuna grows exceptionally well in my garden) and other greens. Slice up some green onions, cucumbers and tomatoes, throw in a few flowers, and whisk together a light vinaigrette to pour over the top. Toss it all together, and yum!

Wait, you say. Flowers? You put flowers in your salads?

Planting Lettuce in Winter

lettuce-bf-2008may30-lah-002Are you staring out the window, watching the snowflakes, and desperately wanting to plant something? Guess what—you can! It may be too early to start tomatoes and broccoli, but lettuce seedlings can handle the cold with a little protection. So pull out the recycled six-packs and potting soil, soak your peat pots, and clear some space on the counter. It’s planting time!

I’ve written several posts about starting seeds (see April 2009 for the basics, or choose “Gardening: Starting Seeds” under Categories, in the upper left of the screen), so I won’t go over all that again. Rather, I’d like to encourage you to push the limits and experiment a bit. Most seed packets contain far more seeds than a home gardener is likely to use, so you can afford to take a few chances.

boettcher-dbg_lah_6645-1Does chaffing wind have you pining for gentle tropical breezes? Do the empty branches of your shrubs and trees leave you starving for bright green foliage? Are you dreaming of the scent of gardenias and orange blossoms?

Wax Begonias—Indoors!

lah_6081What plant thrives indoors, shrugs off low humidity, and blooms all winter in bold shades of white to pink to red? Surprise! It’s wax begonias!

Also called fibrous begonias, these bedding plants have large, round succulent leaves in either lime green or a beautiful burgundy- or bronze-red. Flowers have fleshy petals surrounding a bright yellow cluster of stamens. Plants grow to a height of about six to twelve inches, and tend to flop, creating a solid mass of color, and even trailing over walls and container edges.

Too Much Compost?

 

veggie-garden-student-run-csu-perc-lah-094-1When I first encountered this concept—that a gardener could use too much compost—I immediately thought, “Is that even possible?” As an organic veggie gardener dealing with soil comprised of decomposed granite punctuated by lumps of sticky clay, too much compost seemed an impossibility. Isn’t compost the answer to all our gardening problems?

It’s true that “add compost” (or other organic matter, such as peat moss or leaf mold) is the best advice for gardeners dealing with either clay or sand. Organic matter opens up the solidly packed clay particles, allowing air and water—and therefore roots—to penetrate what would otherwise be an impervious substrate. In sand, organic matter acts as a sponge, holding on to both water and nutrients that would otherwise quickly drain away.

“Days to Maturity”

tomatoes-greenhouse-2008sept08-lah-296When can I pick my tomatoes? Will these melons ripen in my short growing season? If I plant these flowers from seed, when will I have blooms?

“Days to maturity” is one of the most important factors in determining what we can grow in our high altitude gardens. Technically, this number tells the gardener how long a particular crop or variety takes, on average, to yield a harvestable crop. However, it’s all a bit fuzzy.

Amaryllis for the Holidays

amaryllis_gretnala_20090619_lah_4153-1With giant, trumpet-shaped flowers facing outward around a central stalk, a blooming amaryllis makes an eye-catching houseplant. Colors range from white through pink to red (and even almost black), as well as salmon-orange. Stripes or contracting edges are common. “African” amaryllis have more compact forms suited to indoor cultivation. Dwarf amaryllis are smaller in size but can produce more blooms.

Not surprisingly, these striking, easy-to-grow bulbs are popular holiday gifts; perhaps you received one this year. There’s even a bright red variety named “Merry Christmas”!
