September in the Colorado Garden:
r September is a great time in Colorado gardens. If you have the time to take a break from the harvesting, enjoy the flowers that get a second wind as the temps cool off.
r Plan to mulch trees now and perennial flowers when soil temperatures cool in a month or two. Mulch will help preserve moisture into the winter where water restrictions cut off outside watering.
r After the last nectar flow, September is the time for the final honey harvest of the season
r Water trees now to help them set buds and enter dormancy in a healthy condition
r Fall planting of perennials and trees will need supplemental winter watering
r This is an excellent time to tune-up sprinkler systems to increase watering efficiency
