It (Fusilade) is non-persistent in the soil, systemic.
'My' worst grasses are:
- A big clump-forming one, which is impossible for other herbage to compete with. ...Though in some wild areas, it reaches an equilibrium where the plants fill an area as much as they can - but that leaves individual plants spaced-out. In turn, that creates miniature open glades with a light canopy. In spring, those glades can be like a fairyland because they fill with Anemones in pastel shades of pink, blue and white.
- Bermuda grass. I would like this, because it is not too tall, it is exceedingly good at running and binding the soil, and remains green for a lot of the year. But its runners are too prone to invade adjacent areas, and it spreads by seed as well. I do have a rough area where it is somewhat established, and where I may permit it (trees and shrubs will be the main plantings there). But I daren't allow it in the calpops patch, where it could also be too dense for the calpops, et al. to get going. I say 'could' because it does occur to me that the calpops would be starting to grow when the Bermuda grass was subsiding for the winter.
