I moved to the house where I now live in the spring of 2001. There was a lot of tall, lush brome grass in the pasture that year and I learned from my neighbor how to irrigate, to use the few shares of water that came with the place and feed my horses. There was plenty of ditch water that year and I had someone cut and bale my own hay. But the following year everything dried up. We couldn’t see any snow on the back range from the plains. Our ditch water didn’t come. Weeds emer

By Lori Wheat: Xeriscape landscaping promotes water efficiency by using plants that are native and adaptable to Colorado's semi-arid climate. A well-designed Xeriscape can invite wildlife and pollinators, provide year-round interest, and save water.

EcoArts Connections and Suelo Bueno, and with the help of Growing Gardens, are co-creating a program to encourage Boulder County gardeners and growers to grow extra flats of plant starts to distribute to low income families, especially those living at or below the poverty line in Mobile Home/Manufactured Housing Communities (MHCs).

Last week we had a freezing, foggy morning before the sun broke through. I happened to be outside feeding my horse at that moment when the fog dissipated and the iced trees were suddenly glittery against a bright blue sky. As I walked back toward the house tiny white flakes floated down around me, melting before they reached the ground, and I looked up, wondering how it could possibly be snowing under a blue sky with no wind, but it was just the trees shedding their icy coats

Year-Round Vegetable Gardening in Colorado is Possible with a Cold Frame or Hoop House. Cold Frames are basically a small, short version of a greenhouse – more or less a raised bed with sloped lids that trap solar heat to keep the bed warm.

Snow is falling at last! My truck is still half full of dairy compost from Soil Rejuvenation just east of Longmont. Brian, the owner, is a lanky farmer with the gift of gab. His crop is soil and it excites him. For almost 10 years he has been researching and experimenting with materials and learning in depth about soil biology and what makes it thrive.

By Idelle Fisher: Dr. Samuel Ramsey Dr. Samuel Ramsey of CU's Boulder Bee Lab was the engaging keynote speaker on the first day of this year’s Pollinator Summit. With a good dose of humor, he addressed the “wrong bees" topic, describing how our non-native honeybees have gotten a bad rap in recent years because they can negatively affect our important native bees. Honeybees are important for agriculture, but he stressed how vital it is to treat honeybees like pets or livestoc

It’s been a beautiful fall and there are plenty of leaves everywhere for the garden beds. I find there’s nothing better for building soil in veggie and perennial beds, and well as around roses and shrubs, than adding compost and leaves in the fall. Shredding the leaves, especially any thicker, leathery cottonwood leaves, helps them break down faster without matting.

Q: Over the last few years, I’ve collected a number of cacti and succulents. When I look them up online, it shows that they have gorgeous flowers. Mine never bloom. I have them in various windowsills and on tables near the window. Do they have to be older to flower? Do they need a certain kind of fertilizer?
