Autumn Crocus (Colchicum) isn’t just something you’ll find growing wild in meadows—you can easily bring these stunning fall bloomers into your own backyard! If you want to see those gorgeous pops of color right when the rest of the garden is winding down, timing is everything.
Planting Autumn Crocus in the Summer
The Autumn Crocus is a bit of a natural wonder when it comes to speed. You plant them in the heat of the summer, and just a few weeks later, they’re already blooming. How do they do it? Well, these fall-blooming bulbs actually come with the flower buds already tucked inside. Plus, they don’t even need to establish a root system before they start showing off their petals.
Once you get them in the ground, you only have to wait about six weeks before your flower bed or lawn transforms into a purple-hued paradise. Because of that quick turnaround, the best time to plant is during August and September.
How to Plant Autumn Crocus: A Step-by-Step Guide
To get that “carpet of flowers” look, timing is only half the battle. You also need to pick the right spot. These beauties thrive in sunny to partially shaded areas that stay warm and protected from harsh winds. That’s where the bulbs will be happiest.
Here is how to get your bulbs in the ground during the mid-summer:
- Safety first: Always wear gloves before handling these bulbs, as they are toxic.
- Prep the soil: Use a rake to loosen the dirt and clear out any old roots or debris.
- Planting depth: Place the bulbs about 6 inches deep with the pointy side facing up.
- Give them space: Space the bulbs about 12 inches apart.
- Fill it in: Cover the holes with fresh, moist soil enriched with a little compost.
- Finish up: Press the soil down firmly and give them a good watering.
You might wonder why they need a full foot of space between them. It’s because the leaves don’t actually appear until the following spring, and they need room to spread out. Pro tip: Always plant your Autumn Crocus in groups. A single flower is pretty, but a cluster is what creates that breathtaking “sea of flowers” effect we’re going for!
