We have three phormiums in a row. They are a muddy mid-green and are about three feet tall and the same wide. They must have been in place for at least five years, but probably much longer. We'd like to get rid of them and lay a lawn there. Do we need to dig them out or can we just weedkill them and turf over the dead roots? There's nothing around them that would be damaged by glyphosate. The lawn does not have to be perfect.

Thanks.

Interesting. Most varieties of phormium died in most places last winter, the exception being those most similar to the basic phormium tenax plain species. But once in that category are usually at least 6 feet high after 5 years. Even with neglect and a dry location.

I don't know the answer, but I'd try glyphosate. Reason being that digging them out is difficult without a mechanical digger. Good time of year to try.

A local gardening 'expert' was surprised they survived our -18 temperatures last winter. They face full south west onto a south-west-aligned valley, so I suspect that the wind has kept them small. They are very boring looking, so I suspect they are close to the species.

Thanks

Laura welcome to uk.rec.gardening via gardenbanter :-))

A phormium is a pretty tough cookie. We had one in our little garden which
became a thug. The root formation is pretty solid. We wanted to get rid of
it. I dug down and used a carpenters hand saw to slice down and reduce the
roots to a smaller diameter. It was then lifted out, put in the back of a
pick up truck and taken to my daughter and son in law's walled landscaped
garden. It was 'plonked' into a hole in the ground and is now fine thank you
very much :-))

What am I saying? Dig it out.They are tough :-((

Other 'experts' may have different views. I am only talking from stuff
called 'experience'.
