High Altitude Gardening Classes and Resources

| February 14, 2017 | 3 Comments

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

Posting the most recent presentation from a regular class I teach at our terrific local libraries, 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.

*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!
