Conifers for Colorado Landscape & Gardens

Rocky Mountain Gardening Required Course Group II

Urban tree diversity is becoming ever more critical in our local and regional landscapes which have relied on a limited tree palette.

From native species to exotic cultivars, we’ll discuss practical, cultural and design considerations. A morning classroom session will be followed by a walking tour and hands-on introduction to the Gardens' conifer collections.

Seed, Soil, Sun and Water

 

Seed, soil, sun and water are all you need to grow food in the Wild-West! Great news - it still works! In fact, the earth and all its systems already work perfectly and just by combining seed, soil, sun and water you can witness miracles.

If the Rockies can grow a giant Ponderosa out of a rock at 10,000 ft., we can certainly grow food in soil. This class focuses on what already works, how to work with what you have and to inspire you again in nature’s ability to feed you.

 

We’ve been told for years that we cannot grow food in the Rockies but we know that’s not true! Let’s get back to basics and garden the way our grandparents did – using Earth’s amazing resources to produce clean, vibrant, mountain-grown food!

This class will cover each topic in depth with Colorado’s challenges in mind. Saving seed, building soil, managing intense sun and conserving water all can give you remarkable results here in the west.

Penn and Cord Parmenter bring 21 years of experience to this approach and are passionate about emulating nature and chemical-free growing. Everyone can grow clean food and we intend to inspire you to look again, at what is all of ours to enjoy – the abundance and sustenance of nature!

Starting Your Garden from Seed

Rocky Mountain Gardening Elective

 

Few things excite a gardener more than buying new plants for their gardens, especially if the plants are exotics, unusual or heirlooms. Second-only to the creation of new plants is the financial benefit of growing your own plants, whether flowers, herbs or vegetables.

This class will demystify the seed-starting process primarily focused to the novice gardener, but a good review of the best success tips if a more advanced gardener needs a refresher. We will cover simple seed botany and the process of best practices for successful seed germination, successful transplanting, and seed collection and storage and cover some of the reasons seeds and seedlings fail.

After discussion, we will present a hands-on demonstration and students will leave with seed trays and seeds to return home and practice what you have learned in class. This class will help you up your game to produce all the transplants you could possibly need and set you up for upcoming classes on spring and summer vegetable gardening and succession planting.

 

 

$32 member, $37 non-member, includes $5 for materials for a seed tray for seed starting, with all necessary materials to get your garden going this year!
