Cool-Season Veggies are Here!

With asparagus and onions arriving soon!

Now that our cool-season veggies have begun to arrive (see list below) it feels like spring will be here very soon! We are also stocked with seeds for early spring crops (see list below).  We look forward to having you stop by to see them. 

When planting in the early season, it’s important to have a few extra tools on hand.  Soil Thermometers will help you accurately gauge when to plant.  

Row Cover gives you a few degrees warmer temperature, protection from drying sun and wind for seed beds, tender seedlings and transplants, as well as protection from insects and birds. The fabrics can be “floated” over your rows or beds, using weights of various kinds to keep them in place, and can also be used to cover garden tunnel frames. When handled gently, these fabrics can last several seasons.   We have two types of Row Cover fabrics – Ensulate (1.5 lb.) and Seed Guard (.6 lb), both in pre-cut sheets or custom cut from our 12′-wide rolls.

With the aid of Row-Cover fabric, you can plant our Broccoli, Aspabroc, Broccoli Raab, Cauliflower and Cabbage starts EARLY!  Eve has always had her best crops of spring-planted Broccoli and Cauliflower from starts set out in mid-March with protection. For heading Brassicas like these, you could also recycle 1-gallon water jugs, cutting out the bottoms and uncapping the tops, then setting them over the newly planted starts and pressing them into the soil just enough to keep them standing.  You can put the caps on at night, but don’t forget to remove the caps before your plants cook in the sun. 
  We continue to be open four days a week from 9 AM to 5 PM on Thursdays, Fridays, Saturdays and Sundays during the month of March.   Starting Monday, April 1, we’ll be OPEN DAILY! 


This weekend we’re again featuring three great classes.  In keeping with the arrival of our cool-season veggies, Mimi Yanus conducts her ever-popular “Getting Started in Veggie Gardening” class on Saturday at 10:00.  (Mimi will repeat this class on April 6.)   

It’s not too late to get your Mason Bee straws!  At 1:00 on Saturday, Tom Theobald hosts a repeat of his earlier “Mason Beekeeping” class. 

On Sunday at 1:00Kirk Fieseler of Laporte Avenue Nursery in Fort Collins, will share valuable knowledge about propagating and growing evergreens in Colorado (which can be challenging!) in his Dwarf Conifers for Gardens and Landscapes” class.

When the soil has warmed enough, peas can be planted. We recommend pre-sprouting them indoors, and carefully planting the sprouted seeds, sprinkled with legume inoculant (which we have), in soil has warmed up to at least 40 degrees F.  Peas can be planted through April.  We have seeds for Shelling Peas, Snow Peas, and Sugar Pod or Snap peasHere’s some great local advice on growing peas.

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 March Class listing below, or on our website.

Mason Beekeeping with Tom Theobald  

The importance of our native ‘solitary’ bee species to the pollination of our crops, flowers, and native plants is receiving increased attention. For over 30 years, Tom Theobald of Niwot Honey Farm has been propagating one of the most ‘useful’ species, Mason Bees (Blue Orchard Bees), and will teach how to attract and care for these gentle native pollinators. Mason Bees are not a replacement for honeybees, but they are excellent pollinators of the early fruits – cherries, apples, etc.  They stay close to home, don’t sting, don’t require the year-round commitment of a colony of honeybees and provide a great way to introduce children to the world of pollinators. Harlequin’s Gardens will have filled straws (containing male and female adult bees in hibernation) for sale for $12 a straw. 
IMPORTANT: You must RESERVE your Mason Bee straws IN ADVANCE by calling Harlequin’s Gardens at 303-939-9403. Pre-payment of mason bee straws is required. Class cost: $15.  (Note: this class is a repeat of Tom’s March 2 class.)
