What You Need To KnowIf you’re a “fallscaping” rookie, here are a few things you need to keep in mind:What is fall?This probably sounds like a pretty basic question, right? There might be more to it than you think! Your fall season depends greatly on your hardiness zone. So, what are some basic “requirements”?The Fall Season is between Labor Day and the “Fall Back” Daylight Saving Time.Your temperatures should maintain a daytime high below 80 degrees.Your first frost should be at least 10-6 weeks away.What’s the latest I can plant?Our advice: don’t drag your feet! Go ahead and preorder your herbs so that they arrive right on time. What are the dangers of procrastination? Young herbs (especially perennials) need to “harden off” before the first frost, which basically means they need to acclimate and toughen up to lowering temperatures! If they aren’t given enough time for this process, let’s just say… you’ll be left with a pretty sorry-looking plant.How long do herbs need to harden off?Perennials (especially woody varieties) require 8-10 weeks.Annuals and biennials require 6 weeks.Will planting Perennials in the fall hurt them in the long run?Nope! It turns out Kelly Clarkson is right: What doesn’t kill you makes you stronger. Facts show that perennials that are hardened off and experience their first winter as a youngster emerge stronger, healthier, generally hardier, and are more productive in the spring when compared to Spring-planted plants.
