I'm hoping for some advice. I am in the process of digging over narrow-ish (width between 1 metre to 1.7 metre, depending on which side) borders around my lawn. I have found a lot of rubbles and roots (there used to be laurel hedge on three sides) in the soil and just can't dig more than one fork depth. It's combination of a very clay soil and my endurance - double digging isn't made for a 50 year old female
I hope to start planting in the autumn and wonder if this depth is sufficient for most plants? I want flowering shrubs, climbers and perennials for medium to low maintenance and may want a couple of fruit trees on dwarf root stock.
Another thing I'd like to ask is if I need to have the borders 'rotavated'. Although I'm trying to break up the clay soil and mix it with grits (various size, up to 1 centimetre I think), it is still pretty lumpy. I've looked at Homebase website to hire one and it being 90kg, I don't think I can handle that on my own. I've read somewhere else in the forum that rotavator chops up weeds and therefore I'll end up with ten times more weeds. But I'm digging up weeds as I dig over and thinking I might be able to hire someone to rotavate it for me.
I'd be grateful for some advice on these two questions. Thanks!
