We have a lot of trouble with grass growing in our back of the house gutter. I blame the pigeons! We have to keep getting someone in to clean them out. We are thinking that the Hedgehog Gutter guard might be a better solution. Does it work?
I don't think that every year is very frequent. I live in an area with loads of trees and its part of the routine to have the gutters flushed yearly after the leaves are all down.
The reason I blame the pigeons is that I think they transfer the seed we put out onto the roof and it germinates in the damp gutter. My roof is rounded pantile type tiles.
Pigeons alone will surely not be responsible. For seed to germinate, it needs soil, or something like it. Your guttering should be more thoroughly cleaned out, and that involves scraping out any soil that has accumulated under the tiles overhang.
The seeds need something to grow in. Dead leaves and dust accumulate in gutters, and that's enough to give the seeds a start. This shows your gutters really need cleaning out even if nothing's growing in them.
heathfield, great minds think alike, yes? I use a piece of bent wire to scrape under my tile overhang, and now and then I flush the guttering with my hosepipe.
We don't have any ladders and, if we did, my husband wouldn't climb them. Got a man coming tomorrow to give us a quote for gutter cleaning and gutter guard.
