How to Grow Cornflowers: A Step-by-Step Guide

Step 1: Choose the Right Location
Cornflowers thrive in full sun, so select a spot in your garden that receives at least 6 hours of sunlight per day.

To encourage continuous blooming, remove spent flowers (deadheading). This practice will help extend the flowering period well into the summer months.
