High Altitude Gardening Classes and Resources

| February 14, 2017 | 3 Comments

A gardening geek?  Who, me?   (innocent gaze)

Posting the presentation from a class I taught at our terrific local libraries in February and April 2016 and in February 2017, which is fun beyond belief for me. There are so many great people in my community, and it gives me a charge to empower everyone to learn the difference between a real tomato and a nasty store-bought one.  Download from the links below:

*Check your soil and make it healthy: Soil test kits are available at the CSU Extension office in Jeffco Fairgrounds, or at many local nurseries – call ahead to be sure. Jared’s and Echter’s are among the closest ones who have these kits.

Raise it up: Easy raised beds can be built with stone, cinderblock, or 2″ x 12″ lumber and a few screws, or use these super easy corners:   http://www.gardeners.com/buy/raised-bed-gardening-and-garden-boxes/raised-bed-corners/


Need soil?   A-1 Organics sells organic planter’s mix. See them at http://a1organics.com/ and ask them for the nearest retail outlet.


Protect it! Do you need a greenhouse, walls of water, cold frame, low tunnels? The books Four-Season Harvest and Winter Garden Handbook by Elliot Coleman …actually anything by him….is an indispensible resource.

    Wow, this is terrific – congrats! This is great substantive information, beautifully and simply presented. I wish someone would do that for where I live (Zone 7, and a whole lot easier than your neck of the woods.)
    Thanks for the tip about the kelp solution – I lose a lot of plants after transplanting. I do try to be gentle! I don’t know what the story is with that.
    Thanks for another great post.

      Thanks, Gardenarian! The kelp thing has changed my life, I swear. Taught to me by a long-time local gardener who always seems to have these giant, magnificent specimens growing….so I paid attention 🙂 In your neck of the woods I imagine that a good mulch would be super-valuable to keep the soil moisture consistent?

  2. GENIUS! What an awesome guide! You are truly amazing. Thanks for sharing your vast knowledge with the rest of us!
