When and How to Plant Crocus
Planting crocuses in your lawn is a fantastic way to add color to your spring garden; if you plant a crocus lawn in autumn, it'll flower in spring, and then keep flowering year after year.
Do Crocus Bulbs Multiply?
Yes. Over time, your crocuses should naturalise, spreading by seed and giving you a beautiful, floriferous spring lawn.
Do Crocus Come Back Yearly?
Yes, crocuses are perennials, meaning they will come back every year.
Step-by-Step Guide to Planting a Crocus Lawn
The best crocus to choose for naturalisation is Crocus tommasinianus, which yields gorgeous purple flowers every spring.
1. Choose the Right Location
The first thing to do is to choose your spot. An area of neglected lawn is best, where the grass doesn't grow vigorously. Underneath a deciduous tree is the ideal location. Choose an open, sunny position. Don't choose a lush, fertilized lawn; your crocuses won't like the competition from the grass.
Keep in mind that while your crocus lawn will be a mass of color in early spring, that'll be followed by an area of messy, uncut grass for several weeks. You need to be prepared for that.
2. Cut an 'H' Shape in Your Lawn
Having chosen your spot, you'll now need to peel back sods of grass and place your crocuses underneath. Cut an 'H' shape in the lawn. You'll need to cut it to 3 times the depth of the crocus bulbs.
Insert the spade sideways under the flaps of the 'H' and peel back your lawn.
3. Plant Your Bulbs
Place your bulbs in the exposed area, placing them with their flat base down and their pointy side facing up. Now carefully replace your flap of lawn. Firm it down at the sides. If there are holes, use a little compost to plug the gaps.
4. Water in Well
Water the area well. Next spring, you should see lots of little purple flowers poking up through the lawn.
Tips for Maintaining a Crocus Lawn
When your crocuses finish flowering, don't deadhead them, as this will stop them seeding around. Instead, after flowering, allow the plants' leaves to yellow and leave the lawn uncut until the crocus leaves have faded completely.
Lastly, don't use weed killer, don't fertilize and don't aerate this section of the lawn.
May your crocuses bloom magnificently! Happy growing.
