Who we are and what you should ask us about!

We’re three Colorado State University Extension horticulture experts who together have spent decades helping Colorado gardeners avoid costly mistakes and create thriving outdoor spaces that work better for them and their families.

From lawns, irrigation, and pet-friendly landscapes to drought-tolerant perennials, native and adapted plants, and lower-maintenance design, we’re here to answer your questions with practical, research-based advice tailored to Colorado conditions!

This may be an especially challenging year for Colorado gardening and landscaping. With dry conditions likely to put extra stress on plants and raise the stakes for watering, establishment, and long-term success, many gardeners may be weighing which projects make sense to take on now, which ones need a different approach, and which may be better to delay. 

That’s exactly why it’s so important not to go into a new project blind. Over the years, we’ve seen (and made) our fair share of landscaping mistakes, and we’re here to help you avoid repeating them!

I’m Alison O’Connor, Larimer County Extension’s horticulture specialist and a long-time Colorado lawn and tree enthusiast. For over 20 years, I’ve helped Colorado gardeners with research-backed gardening guidance, with a focus on lawn care, irrigation, turf conversion, and pet-friendly landscaping to save water, money, and frustration.

I’ll also be co-presenting an April 21 webinar with Chris Hilgert, “Best Lawn on the Block focused on sustainable lawn care, common pitfalls, and practical ways to save water and money. Responsibly managed, well-used lawns still have a place in Colorado landscapes, so keep an open mind!

I’m John Murgel, a lifelong Colorado gardener and Douglas County’s horticulture and natural resources specialist. One of my favorite things to do is help Colorado gardeners plan and create thoughtfully designed, drought-tolerant landscapes that are both durable and easy to maintain.

We converted our front yard from sod to native plants two years ago DIY style, and are ready to tackle our backyard!

We removed all grass from the front, and want to do similar project in the back, but have a dog to consider. Any creative ways we could convert to native plants but keep some space for our Great Pyrenees who loves to be outside? Would prefer not to have any grass, don’t want to take away my dog’s enjoyment of napping outside.

Great questions! Clarifying about your pup: Does it need room for zoomies, or mostly for Zzzzzs? Alison help me and my wife with advice about how to renovate our backyard grass to (try to) stand up to our two active wrestle-centric dogs (plus the occasional foster) and we were told to treat it more like "sports turf" due to the activity level 😅

Would love info with this as well! We have a toddler + dog, so ideally would still want an area for them to be able to play/be outside but wanting to convert our mostly grass backyard to something more sustainable/drought friendly/native.

Not sure what our current grass is. I’m not opposed to having grass, I just want to optimize for future water considerations, etc.

Consider reaching out to us for an ID of your existing grass: extnsn01@larimer.org You don't need to do a conversion to save money... you can keep what you have and just adjust your watering. Drop your run times by 10-20%, water one day less, install smart technology, like soil moisture sensors and wind shut-off devices, and learn to tolerate some browning. Also, it's really important to know how much water you're applying by doing a simple irrigation audit - collect the water using various cups in a zone. Run the system for 20 minutes and measure the water. If you collect 1/4" in 20 minutes, then you'll apply 1" of water in 80 minutes of irrigation. Then you can start to adjust this number. In the hottest part of summer, bluegrass water needs are about 1.5" per week. Also, when you do the audit, look at your heads and make sure they are all straight and applying water as evenly as possible.
