Is Your Evergreen Brown? No Need to Frown
By Kirsten Saunders, Apprentice Master Gardener
Last winter wasn’t so hard on me. Most days were bright and we rarely had to pull out our trusty snowblower. Last winter, however, was terrible for my evergreens.

First, temperatures plummeted over 50 degrees in 24 hours in mid-October, shocking the evergreens before they were hardened off for the winter. Then, came a dry, windy winter that stripped needed moisture from the needles and caused winter desiccation.

My Ash Tree Didn't Leaf Out!
We have been receiving many calls this summer about trees not leafing out. Are they dead? What do I do? What if my HOA wants me to remove my “dead” tree? Will the tree bounce back?

Colorado is a tough place for trees to grow! In addition to a dry winter, last October and last April we had extreme, sudden temperature changes that impacted many trees. Trees didn’t have a chance to prepare for those weather events, and now we are now seeing the results. Ash trees were significantly impacted. You may notice damage on other trees including catalpa trees, crabapples, some maple trees, and other fruit trees. Conifer trees were also impacted. You may notice new brown needles on your pine and spruce trees or large portions of juniper trees that turned brown.

Healthier trees will likely bounce back, while stressed out trees may not fare as well. However, it is too early to know how trees will do long-term. The best thing to do is wait and see what happens, and keep your tree as healthy as possible. A few tips include:

  • Is your tree alive? Even if your tree didn’t leaf out, it may still be alive. You can check the branches. If you scratch the branch, and see green underneath, the tree is still alive. If most of the branches on your tree appear brown underneath the bark, the tree might be dead.
Growing Vegetables in Containers
By Kathi Thistlethwaite, Colorado Master Gardener
This is the first of a six-part series focusing on container gardening in Colorado .     
While most vegetables can be grown in containers, follow these steps to help your vegetables thrive. Gradually acclimate your vegetables to the outdoor conditions before you put them outside permanently. This is known as hardening off and should be done with all potted cultivars.
Choose containers that please you and give you the look you seek in your landscape. The larger the container, the more soil and moisture it holds. Material and shape are mostly a matter of preference, as long as there is good drainage and the container is made from a food-safe material. When choosing your containers, remember that those made of metal get too hot and treated wood can leach chemicals into the plants. Containers should be 12 inches in diameter or larger.

Use Indicator Weeds for a Healthy Lawn
By Pam Rosendal, Colorado Master Gardener
Summer is here. Trees are green and flowers are blooming, and so are those darn weeds! Every year homeowners fight weeds in their lawns and every year they come back. With a little detective work and some changes to your lawn care program, weeds can be kept at bay.

Of course, the best defense against weeds in the lawn is good maintenance.

A thick healthy lawn will choke out most weeds over time. That means proper watering, fertilizing and mowing. Refer to CSU’s fact sheet on recommended lawn care practices.

Extending Excellence Regional Award
By Tim Aston, CSU Extension Arapahoe County Director and Judy Kunz, Colorado Master Gardener
And the winner is . . . Arapahoe County's Master Gardener Coordinator and Native Plant Master Lucinda Greene! Lucinda conceived and spearheaded the planning and installation of the Native Plant Pollinator Garden located at the Arapahoe County Extension Office in Centennial.

The turf was completely removed and the garden was installed to replace it. With the assistance of County Horticulture Agent Lisa Mason, the support of individual contributors, a grant from the Colorado Garden Foundation, corporations and vendors within the community, Master Gardener program revenue and the help of many volunteers, the vision of the garden took shape and became a reality.

The garden serves as a community engagement opportunity for Arapahoe County, focusing on native plants and pollinator education. Its purpose is twofold--sustainability education and research that mutually benefits county residents, county employees and CSU Extension. This initiative, the first of its kind in the county, will be used as a teaching tool and sounding board enabling community members to be empowered in making landscaping choices that are ecologically conscious.
Botanic Road Trips
By Martha Kirk, Colorado Master Gardener
In need of some garden therapy? How about a road trip? Summer is the time to get outside and smell the flowers. Literally. We put together a list of recommended places where you can enjoy the beautiful outdoors and colorful gardens. So, gather the family and get going.

If you’ve never been to the CSU Annual Trial Garden, it is worth the visit. This public garden features a stunning display of colorful annuals from late May through October. Roughly 25 plant companies from around the world send 1000 new cultivars each year to CSU to be tested. Dr. James Klett and his team of research students at CSU monitor and evaluate the performance of these plants in Colorado’s unique environment of high altitude, intense solar radiation, drying winds, severe hailstorms, large fluctuations between day and night temperatures and a season-long need for irrigation. Also check out new perennials that are tested and evaluated. The perennial garden is located across the street in front of the Center for the Arts.
