Do you need to water in the seeds ?
No - it’s a winter growing season in SW Australia.
I do have one, that I use for getting the leaves off the roof and out of the gutters. It's a classic kludge of the vacuum/blower, pool hose and a mount made of plywood sitting on top of the green recycling bin. I'll take a photo of it this week end and post it up.You just need a leaf blower that sucks (and mulches).
I do that to start with, until I fill up the compost bins. Thankfully there is a green waste centre near our place, so I can fill up the flexible garden bins with the extra leaves and take them there.Or run over them with a mower, which is what swmbo does, into a catcher and then into the compost bin.
In theory....... although here in the UK it then turns into dangerous slippy slush as the rain mixes with it! If only the high rates of Council Tax we paid would cover the footpaths etc. being cleared..... oh, wait ........Autumn is lovely, when it’s on the councils footpath and not your backyard !
