Gardening in Douglas County

The key to gardening in our region is working with the climate and landscape instead of against it. We have more sun then many places on earth, low humidity that keeps most diseases at bay, and cool nights that create ideal growing conditions for many plants – they just might not be the same plants that grow in most other places. While rhododendrons, hydrangeas, and boxwood could be a challenge in our conditions, CSU Extension can help you to discover the plants that work in Douglas County and give advice on how to maintain and care for your garden.

It’s Mud Season!
Don’t work your wet soil! Digging or even walking over very wet soil can cause structural problems that take years to correct.  Wait until things dry out a bit before planting those spring plants!

If you applied extra mulch on any plants to “tuck them in” for the winter, start checking for signs of new growth at the plant crown and remove mulch as needed over the next month.  

It’s almost time to remove tree-wrap!  Tree trunks protected from the winter sun with paper tree-wrap should be uncovered around tax-day–April 15!
