Field pennycress is a very common annual weed, appearing in both cultivated and uncultivated bare soil throughout the garden.
Plants grow quickly, and each one produces hundreds of seeds. Plants grow quickly, covering beds and borders and grow through cultivated plants.
These seeds can also remain dormant in the ground for several years. And as “One year’s seeding means seven years weeding”, allowing plants to flower and produce seeds, means several years of trying to control and remove it.
