Denver's Dirty Little Secret (Spoiler: It's Not That Dirty)
Now, Denver sits on a bit of a climate seesaw. Some years, it's a cozy mountain retreat, others...well, let's just say you might need a cactus for company. That's why Denver's plant hardiness zone is actually 5b-6a. The "b" and "a" represent slightly different average minimum winter temperatures.
Here's the breakdown:
Tip: Read the whole thing before forming an opinion.
- Zone 5b: Where you can expect the temperature to dip down to around -15°F (ouch!)
- Zone 6a: A slightly balmy (hey, it's all relative) -10°F
So, What Can You Actually Grow There?
Now that you're armed with this top-secret knowledge, you can hit the nursery with confidence! Here are a few things that Denver's funky climate approves of:
- Veggies: Think cool-season crops like lettuce, spinach, kale, and peas. You can even try your hand at some herbs!
- Flowers: Pansies, poppies, columbine, and black-eyed Susans will all add a pop of color to your garden.
- Trees: Evergreens like spruce and fir will do well, or you can try some deciduous trees like maples and oaks.
But wait! There's more! Here are some helpful tips for your Denver garden:
- Pay attention to the frost dates: Denver's got a short growing season, so knowing when the last frost is likely to happen will help you time your planting perfectly.
- Water wisely: Denver can be dry, so make sure your plants get enough water, but don't drown them!
- Mulch like a maniac: Mulch helps retain moisture and regulate soil temperature, which is super important in Denver's fickle climate.
