I started Hairy Vetch last fall in sections where there's no grass, mainly to add nitrogen to my clay soil. It's growing pretty well after a few months, flowering, and starting to get long and sprawl over the lawn. Should I take steps to prevent it from getting established in the lawn? This is in south central Texas.
I haven't seen any seeds develop yet. The seeds I purchased were fairly big considering how tiny the flowers are, so I should be able to spot them. The young sprouts were easy to recognize, and I'm not averse to hand pulling some next year. The plant is indeed 'hairy' with tiny spikes that are rough on the skin.
