Wise advice from our local experts! 🐝 🦋
It’s about that time again...to let you know that it is NOT time to cut back your perennial gardens yet.
Once this evening's thunderstorm threat passes and the sun starts shining again tomorrow morning you may be tempted to get out and spend the warm weekend and week ahead working on some garden clean-up, but don’t be fooled! Even though it *seems* like Spring has sprung, remember that this is Nebraska and the weather can and does turn on a dime!
You may have heard the general rule of thumb that it is safe to cut back your gardens (which ideally were kept intact since last Fall) once the day temperatures reach a steady 50 degrees F. While we're definitely going to be a lot warmer than that this weekend and throughout next week, the second part of the rule also requires that the threat of a hard freeze has completely passed. The average last freeze in Lincoln and Omaha generally occurs sometime during the last week of April, so we still have the potential for a lot more Winter weather, and keeping those dead sticks, stems, and leaves around just a little while longer is imperative to ensure that all of the native insects and other critters utilizing those materials for shelter still have access to them when the temperature, and likely more snow, inevitably falls again.
So please, we ask that you resist the urge to clean up your gardens this time of year and wait until at least mid-, if not late-April. The pollinators will thank you!
And as always, when it does come time to cut everything down for the year, remember to try and leave approximately 12-18 inches of the dead stalks standing so that our many species of stem-nesting bees can utilize them to successfully rear their offspring, both this season and next.
