If the conditions are right they will come of their own accord
Good luck with the transplant.
I once moved a very old Rosemary with hardly any root when I dug it up,10 years later and it is still going strong!
All my Clematis are the sort you prune hard back each spring.I was trying to just trim back some of the shoots today as they are growing through shrubs etc.They are all shooting out as they would next year so is it OK to cut hard back now?
Or a nice Pyracantha! I have been pruning one today armed with gauntlets and still got scratched and prickled!!!
Worm casts so basically just soil,they brush away easily if dry!
Your slime mould could be Fuligo septica also known as Dog Vomit!
From what I have found out about it it does not seem to be toxic.To get rid of it just let the area dry out.
I agree,you need to start from scratch!
Very easy! Just tug bits off and stick it where you want it,roots or no roots it should be OK!
It also goes to show that you need a plan and some organisation to remove/fit the panels.
If a burglar or whatever wants to get into your property a fence of any kind will not stop them!
It is not an easy job to slide out panels (it is generally a 2 man job) and also depends on what is growing next to them.Mine are in my back garden so only my neighbours on each side.
Tricky to move but easier than replacing a whole fence!
