When buying and planting one of these 5 types of crocus you should make sure that the corms are firm, unblemished, with few or no tears to the outer coating.

I am recommending five specific types of Crocus that are simple to grow and care for regardless of your experience.

When the typical gardener thinks of Crocus they are thinking of Barr’s Purple Crocus.

This type of Crocus has a slender neck, purple flower, and opens up to a bowl shape figure that has purple, white, and yellow colors.

  • Bloom Time: Early Spring

Firefly Crocus may be one of my favorite crocus flowers on this list and features light lavender colors and even bright yellow colors.

Not only that, but this type of crocus is deer-resistant, rabbit-resistant, and even chipmunk resistant.

What sets this flower apart is that you can plan is in grass, in a flower garden, or even indoors.

If you do plant it outside you should plant at least 10 together and don’t be surprised if your garden soon looks like a crocus meadow.

Not only that, but these are incredibly fragrant crocus and are perfect to be cut and displayed indoors.

The most popular types of Double Crocus include Abigail, Allegretto, Blue Diamond, and Double Sugar.

They are a very hardy flower that will come back every spring if you plant them in the fall.

It should be noted that this type of crocus is not deer or rabbit-resistant, so you should plant them in between deer and rabbit-resistant flowers and plants.

D) Blue Moon Crocus

It should be noted that this type of crocus will bloom early in the spring, but is often planted with mid to late blooming crocus.

Step #2. How to Grow Crocus from Corms

Crocus are a beautiful flower that blooms in early to mid-spring.

Unlike conventional thinking, Crocus are perennial flowers.

Most flower gardeners think Crocus are annual flowers because hybrid crocus can become weakened perennials over time.

Step 1 – Plant Your Crocus Corms in the Fall

First, make sure you buy your appropriate Crocus on Amazon on another reputable garden vendor.

Plant your crocus corms in the fall when your soil has cooled off & the temperature is between 40 to 50 degrees Fahrenheit. Plant your corms before the first frost!

Take the temperature of your soil and ensure that it will stay below 60 degrees for 12 weeks or think about planting your crocus in pots.

  • Hardiness Zones 3 – 5: Plant in September
  • Hardiness Zones 6 – 7: Plant in October
  • Hardy Zones 8 – 9: Plant in December

*Find Your Hardiness Zone HERE*

Step 2 – Prepare Your Soil THIS Way!

Locate the area of your flower garden or yard where you want to plant your crocus.

  • Crocus do best in an area that receives partial to full afternoon sun.
  • The soil should be well-draining and should be neutral to slightly acidic (6.0 – 7.0 pH level).
  • The flower garden should be well protected from wind and heavy rain.

Mix 3 inches of Flower Garden Soil to the top 6 inches of your garden soil.

Step 3 – Simply Plant Your Crocus Corms

To have the most success planting your corms you should simply dig a hole 8 inches deep and plant 10 crocus corms next to each other.

*Make sure the Crocus Corms “pointy” part is facing up*

Then mix flower fertilizer (that has a 10-10-10 NPK ratio) in the hole (according to the instructions). And then fill the holes with your flower and garden soil mix.

Next, water your crocus corms for 15 seconds. This will help promote the start of root growth. Continue to water your corms for 15 seconds once a week for the first month.

Then continue this process for as many corms as you want to grow. Make sure to spread each set of 10 crocus corms 4 inches apart.

Step 4 – Do THIS in the Winter

In the beginning of winter you will want to mulch your flower garden bed.

After you mulch the flower garden bed do nothing else to your crocus corms the rest of winter.

Step 5– And do THIS in the Spring

Once the year becomes spring and your crocus grow leaves then you should add flower fertilizer again.

Then water your crocus once a week until your crocus bloom.

As soon your crocus petals fall off the flower deadhead it.

And make sure to keep your leaves on the flower for 6 weeks while your flower absorbs and retains energy for next year’s bloom.

Step 6 – Maintain minimal maintenance in summer

Once it becomes summer you should cut the stem and leaves of your crocus where it meets the soil.

Do not water your crocus in the summer. Do not fertilize your crocus in the summer. Simply leave your tuli in the ground all summer.

If you want your crocus to last longer in the vase then you should add Miracle-Gro for Fresh Cut Flowers.

#5. How Do I Protect my Crocus from Pests

The biggest threat to your crocus is deer, squirrels, and chipmunks. This is both when your crocus is growing and blooming.

To prevent your corms from digging up place bird netting over the ground where they are planted.

If you are trying to prevent deer then you should use deer repellent. If this does not work then grow your crocus corms in pots and containers out of the deer’s reach.

#8. What types of Bulb Should I buy?

Purchasing Crocus Corms is a much easier task than say vegetable or herb seeds, where you have to worry about GMOs, Organic, Heirloom, etc.

When buying crocus corms you should stick to hybrid or heirloom. These will give you the best success in growing Crocus.

Hybrid Crocus Corms are weakened perennials that may or may not come up every year.

Heirloom Crocus Corms are perennial corms that come up yearly but have a higher risk of contracting a disease, harmful insect, or fungus.

Just as important is where you buy your corms from. I recommend buying your seeds from Amazon. This will provide you with the best price and quickest delivery.

#9. What Type of Gardening Pot Should I Buy?

Buy a 5-gallon pot.
