Plant Sale in Denver this Weekend!

By Alexis Alvey, Horticulture Agent, CSU Denver Extension

The Denver Master Gardener 9th Annual Spring Plant Sale will take place this weekend, May 17th and 18th!  On Saturday, doors will open early at 8:00am and stay open till 3:00pm.  On Sunday, the sale begins at 10:00am and ends at 3:00pm.   The sale is located in front of the CSU Denver Extension office at 888 E Iliff Ave, Denver 80210, in the northeast corner of Harvard Gulch Park, with the cross-street being Emerson.

The Spring Plant Sale offers a unique variety of heirloom and modern tomatoes, sweet and hot chili peppers, select vegetables and herbs, and annual and perennial flowers.  Denver Master Gardeners have been working hard all spring in the City Greenhouses in Denver City Park, operated by Denver Parks & Recreation, growing almost all of the veggies and herbs available at the plant sale.  It has been a great opportunity and hands-on learning experience for the Master Gardeners.  Working alongside Parks & Rec staff, they began seeding in March and have provided the tender loving care that each plant deserves.  The plants are now super healthy and ready to be taken to your home!  Below is a list of all the varieties being grown by the Master Gardeners.  The remainder of the plants are obtained from Colorado nurseries and helps support the local horticulture industry.

At the Spring Plant Sale, Denver Master Gardeners will help answer any of your gardening questions and will help you choose the best plant varieties for your particular needs.  All proceeds from the sale support the CSU Denver Extension Horticulture Program.


The Spring Plant Sale is a great community event, so make sure to stop by the other booths including Plant-A-Row for the Hungry where you can get free seeds!, the gently-used gardening items for sale booth, the Rosedale-Harvard Gulch Neighborhood Association, and the 4H Kids-Grown booth!  For more information, call 720-913-5270.  The event is rain or shine (or snow!).  Cash only, please.  See you there!

Sixty Second Secrets for Gardening Success: Frost Dates!

Today on Sixty-Second Secrets for Gardening Success: Frost Dates!

Because frosts kill tender plants and seedlings, knowing the average frost free date in your community is an important tool for aiding in successful gardening. 

As a rule of thumb for Colorado, the average last frost free date is around Mother’s Day. It is important to note that this is an average date. In some years, the last frost can be as early as April, or as late as June.

In the autumn, the average first frost usually occurs around the first week of October. Again this is only an average, and some frost can occur as early as mid September or late October around Halloween.

You can extend your growing season by placing a hoop house or covering your plants with a sheet of clear plastic to protect against light frosts.

For more information on gardening, contact your local CSU Extension Office.
