Advice re using a rotavator

I have a first stage lay out design plan which a friend, who is a garden designer, did for me but decided to save my money for plants rather than commission her to do a planting plan as well!

Looked at the picture you posted, yes that is a mammoth task.
I don't know how quickly you want all this done, but maybe you should have a really good think before you decide at all.
Otherwise you will end up with a ( very long ) sloping border against a fence,
which is what you have now, except it will be planted up.
My ,albeit amateur, eye says you should get rid of the straight line.

I have posted a picture.. I think I over estimated length probably nearer 70' but still a task!!

Looking at the size of this bed - 90 feet by 8 feet - is that right?
If so, that is huge.
Therefore it may be a good idea to get some strong men in, provided you know a good firm. Not cowboys.

No it is not ground elder! The ivy has been allowed to cover the ground as well as the fence along with the brambles. Herb robert & creeping buttercup too!

Please do not mention ground elder. Ever. Again.
The stuff of nightmares.

Do you have ground elder?

We have a rotavator since my husbands back has been dodgy - for the allotment. It does the job but will chop all the roots into bits and from each root will grow another weed, so be prepared to use the hoe constantly - also I suspect that if you never dig you may cause a pan to form but if you grow spuds that should sort it really
