Dumb Question Amnesty!
Hello - new to home ownership and gardening so would really benefit from some advice! Be gentle.
I've just bought a great family home but there's one aesthetic / kerb appeal area I really want to address for my own reasons.
Our tarmac driveway is separated from our next doors tarmac driveway by an unsightly strip of rock hard, stony ground about 50cm wide. The strip is owned by the next door property and the property currently doesn't have anyone living there.
I want to create a natural barrier of sorts between the two driveways without entering into any border disputes and without the effort of trying to turn the stony strip into some kind of habitable environment for plants/shrubs.
It doesn't have to be pefect, it's more to create a proper defined area for us and for them.
So, I was thinking about buying some long, deep troughs and planting the right kind of trees/plants/hedge that will slowly grow well and strong over the next year or so.
It would be nice to end up with a natural green looking partition of sorts that was around 5ft in height and that I could maintain on a regular basis. I'm thinking these troughs need to be about 40cm deep but need advice on what trees/plants could be supported in such a trough and how much maintenance I'm letting myself in for.
Does anyone have any ideas on what thick bushy plants may form the perfect barrier for me in this regard? I've seen leylandii may do the trick but can't find how well it would thrive growing in a trough!
My worst case scenario is that I spend hundreds of pounds on plants/shrubs and I kill them through ignorance or lack of experience so recommendations of species that don't need an awful lot of maintenance would be very welcome!
