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

To have the most success planting your bulbs you should simply dig a hole 8 inches deep and plant 10 astrantia bulbs next to each other.
*Make sure the astrantia Bulbs “pointy” part is facing up*
Then mix flower fertilizer (that has a 10-10-10 NPK ratio) in the hole (according to the the instructions). And then fill the holes with your flower and garden soil mix.
Next, water your astrantia bulbs for 15 seconds. This will help promote the start of root growth. Continue to water your bulbs for 15 seconds once a week for the first month.
Then continue this process for as many bulbs as you want to grow. Make sure to spread each set of 10 astrantia bulbs 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 astrantia bulbs the rest of winter.
Step 5 – And do THIS in the Spring
Once the year becomes spring and your astrantia grow leaves then you should add flower fertilizer again.
Then water your astrantia once a week until your astrantia bloom.
As soon your astrantia 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 astrantia where it meets the soil.
Do not water your astrantia in the summer. Do not fertilize your astrantia in the summer. Simply leave your astrantia in the ground all summer.
