People either love or hate oxeye daisies. Those who hate them sometimes refer to them as "noxious weeds" and work vigorously to rid lawns and gardens of them. A single oxeye can produce hundreds of seeds, which can remain viable for several years. Those who love them enjoy how these hardy and fast-growing plants fill in landscaping problem areas. Scatter seeds anytime and anywhere in full sun or partial shade, and they'll sprout in a couple of weeks. Protecting these daisies takes little work. And, if you do so, you'll be rewarded with copious cuttings in the summer.
Mow your lawn---right over the oxeyes if you wish---beginning in early spring. Stop mowing over the daisies in early May, and they'll soon pop right back up. Rugged oxeye daisies will be ready to bloom in a few weeks, regardless of having been cut back.
Cut fresh oxeye daisies for indoor arrangements from June to August. Avoid mowing the plants while they're blooming throughout the summer.
Deadhead flowers conscientiously as soon as they begin to fade to avoid excessive natural reseeding. Collect spent daisy blooms in August to save seeds, if you wish.
Resume mowing over the oxeyes after they've completed their blooming cycle in August. Or just leave them alone, if their presence doesn't annoy you and they're not on your regular mowing route. They'll be fine either way and return to bloom again next year with no assistance.
