Rain, Go Away!

Gardeners appreciate summer rain, especially ones that live along the Front Range of Colorado.  We just don't get enough rain annually or seasonally to be happy, or should I say for our plants to be happy.  So we adapt and plant water thrifty plants, amend and mulch as told and hope for the best.  Every so often Mother Nature surprises us with too much rain.  She did this in September of 2013 with 500-year flooding in some areas and this week another round of cats and dogs.  My rain gauge measured just over two and half inches in less than 48 hours.  Please stop.  Below are some photos of some make shift shelters I tossed over the raised beds.  I figured that it was best to repel excess moisture and battering to prevent disease issues that may infect the plants.  I hope the humidity underneath didn't make matters worse, time will tell and I'll keep you posted.

Battle of the Ash Borer

Read an excellent piece on the history and research that is currently taking place on the Emerald Ash Borer by Matthew Miller of the Battle Creek Enquirer.

Swiss Chard Charm

Spring planted Swiss Chard!  It was an excellent season for leafy greens.  They won't be missed for long, more plants are seeded.  Swiss chard can take the heat so I grow it all summer and use it like cut and come again lettuce.  Check out "Bright Lights," "Golden," "Peppermint" or "Electric Neon Blend" for some color pop and flavor. Baby leaf chard is ready in just 28 days or wait for the bunch in 55 days.  We steam it lightly then sprinkle with a nice balsamic vinegar.  Swiss chard is chock full of antioxidants, right up there with spinach... makes you nice and strong.   


From Tony Koski, PhD Weed Look-Alikes

Few gardeners are turf weed experts, but Dr. Koski from Colorado State University helps us with photos and explanations, check them out on the link below. He covers crabgrass, bromegrass, annual bluegrass, tall fescue, orchardgrass, yellow foxtail and bermuda grass. GREAT photos!  Bookmark it and refer back often, especially when you're reaching for some kind of broad spectrum weed spray, you better know what weed it is first!  And try digging it out, weed pulling is good for the gardener's soul.

Time to Tidy up the Place

Ah...mid-July, no dog days of summer yet.  We're drying out after a few unsettled weeks of hail and moisture, plants are growing, and the days are flying by.  Summer has finally arrived in Denver.  Gardeners don't often complain about rain, but hail is a sure downer and can cause even the most optimistic gardener to feel a little blue. There's no time to cry in your ice-tea, be thankful for the moisture, now grab your shears and get outside, it's tidying up time. 

Spring and early summer blooming perennials and many annuals can use a haircut or close shave right about now (especially to clean up hail damage).  If you're not sure, take a look at your salvia plants, they are the easiest plants to practice on. The flower heads are crispy and sending seeds everywhere, not that that's a bad thing.  Re-seeders are easy to pull later or let them grow and fill up open space.

Does your plant look like this?


Salvia, along with catmint, blanket flower, coreoposis, cranesbill geranium and many more will re-bloom if regularly deadheaded or in the case of this salvia, taken down to the base of the plant. Once it's flopped open and finished blooming, nothing will help it re-bloom except a deep shearing. Or you can live with splayed plants for the rest of the summer until next spring after a long winter. Then remove the dead foliage as you do with spring clean-up. But that's a long time to wait for another flush of bloom and enjoyment. Cut it back now.

Below is what it looks like right after a heavy pruning, or what a long shouldered haircut would look like when cut to a bob length. Hair grows back quickly too, so in a few weeks this plant will be growing new locks!

Some perennials like peonies are once bloomers, nothing wrong with that, we enjoy their flowers then their foliage, which is lovely to view all season.  Check this list of other common plants for additional tips on deadheading or cutting back. To Prune or Not to Prune

Vegetable Planting Calendar

The third vegetable planting season is here - mid-July.  There is plenty of time to seed many different crops that will mature in about sixty days. This is based on a mid-October hard freeze.

Scroll over to the right to view the Fall Planting column.  You may have to tuck in the seeds here and there, wherever you have room for them to grow.  Keep in mind that later in August, even early September you can seed lettuce, spinach, arugula and radishes, the quicker maturing cool-season crops. 

Cool-season vegetables and herbs that can be seeded right now include beets, Brussels sprouts, cabbage, cauliflower, cilantro, Swiss chard, celery, collards, bunching onions, parsley, peas.

Warm-season vegetables and herbs that can be seeded right now include basil, bush beans, slicing cucumber, okra, New Zealand spinach, summer squash.
