Bountiful Roses for Your Garden

Roses are now in full swing! In spite of a cool spring, late frosts and less sun than we are used to, the roses are glorious. The voluptuous and mostly very fragrant David Austin English roses love this wet weather. Even the Canadian Roses that are adapted to windswept prairies so they are cold-hardy, disease resistant and repeat blooming, are full of blossoms. And of course our Heirloom and Shrub roses are also looking good.  (Pictured above, Rose de Rescht.)

There are so many different kinds of roses with different flower forms and fragrances, that it is really best to choose them when in  bloom. Ours are in full bloom now and all of ours are grown on their own roots which means that they are not grafted, will be hardier, produce more blooms and live longer. Come out and see the wide selection of what we call “sustainable roses” — roses that prosper in Colorado without needing pesticides and fungicides, that do well with just 2 feedings a year and that need minimal pruning.  (More on rose feeding, below.)

Harlequin’s Gardens is famous for our roses! We have been specializing in roses for 25 years. If you would like to see Harlequin’s roses in action, visit the Boulder Dushanbe Teahouse. That garden is also the demonstration garden for the Boulder Valley Rose Society who have maintained them for 21 years with our help and Mile Hi Fertilizer.

Harlequin’s Gardens will be CLOSED Thur., July 4, on Independence Day!

In a long standing tradition, Harlequin’s Gardens celebrates Independence Day by taking the day off and being closed on Thursday, July 4.

Mile Hi Rose Feed and Alfalfa Meal 

We like Mile Hi Rose Feed because it is formulated for Colorado soils, almost 100% organic, and contains 12 essential nutrients and trace minerals for roses, adds organic matter, and supports microorganisms. We’ve been using this for 18 years at the Boulder-Dushanbe Tea House with great results. 

We recommend mixing one cup of Mile Hi Rose Feed and one cup Alfalfa Meal, distributed throughout the drip-line of each rose.  (Once-blooming roses generally get by on less feeding than repeat-bloomers. For patio roses, reduce the amount by half.)  Work the mixture into the soil with a hand-trowel and water well. Apply once in the spring around Mother’s Day, and once in the late summer before Labor Day.  

Roses always appreciate occasional top-dressing with compost or well-rotted manure, too.

Our weekends are loaded with great classes you won’t want to miss! Our customers tell us that our classes have given them tremendous value, with practical and current information from local experts who have spent years honing their skills in Colorado and will help guide you to success. We are charging $15 (unless otherwise stated) for our classes to support our speakers and Harlequin’s educational direction. It is best to pre-register for these classes both in case they fill up, or too few people register and we have to cancel. Pre-payment assures your place in the class. You can register at the nursery, by mail, or by calling 303-939-9403. We are unable to take class registration by email at this time.  Most of our classes run from one-and-a-half to two hours in length, and sometimes longer for hands-on classes, or if there are a large number of questions.  See the complete listing on our website.
