How can I get rid of wild onion weeds in my pots of other plants?

Question

I live in Malta and do not have a garden. I have a lot of plants in pots that live on my terrace. I have been pulling the weeds out 2-3 times a year and snipping off the flowers which come in spring to avoid the millions of tiny seeds spreading. However as the tiny bulbs have wound themselves around the roots of the plants I can never entirely get rid of them and pulling them up only stops them until the bulbs I can’t get at grow again fairly quickly. Have you ant advice on how to deal with them more effectively, please?

Answer 1

If they are wound around your desired plants then the only thing to do is to dig out your desired plants and rinse off all the soil (and bulblets of the onion plants) and replant in new soil. Check weekly for new weeds and pull them up right away before they get hold.
