Hi everyone...I'm new to this forum, but wanted to see if anyone could help me. I have a strange problem. My yard is completely over run with Nastertiums.
Normally, (according to what I've read online) this is a good thing. But in my case, I'm trying to re-design my yard, and they are problematic. For the past 5 years or so, the house I live in had a wild yard. Whoever lived there before, laid seeds (they look like little bulbs actually) for clover and Nastertiums. I live in Southern California, so they come back every year.
Recently it rained for 4 days - it's the start of our rainy season, and after a week, my whole yard was sprouting these pesky plants. I am trying to get the low lying ground cover I planted in the early fall to grow, (a couple varieties of flowering thyme), but they aren't nearly as successful as the Nastertiums and clover. I've basically had to weed my entire yard, and that's not an easy task.
My question is this: How can I get rid of them permanently? I want to keep small bunches of them in isolated parts of the yard where people won't be walking...or as border. I've already planted half the yard with the thyme, so I can't just put down a chemical that will kill all the greenery. I'm hoping someone can tell me something about weeding them, or ways to keep them from re-seeding.
