Using Ecoplugs on side growths and suckers

[Philadelphus]

Advice please?

My problem is a large lime tree, cut to about 3m stump in late '23, as part of subsidence damage mitigation required by insurers.  Intention was, rather than cutting to ground level, to preserve as dead stump and incidentally save some of the well-established ivy to support biodiversity - apparently common practice in ecological conservation jobs. However, the lime resprouted vigorously in the following year, not surprising I suppose from such a monster.  Insurers, told the treatment hasn't worked, have refused to pay for more and have advised keeping as part of clipped hedge - ha ha; during the season the shoots appear to grow by about a foot a day.  Not like privet! 

I've cut all side 'shoots' (= small trees) and suckers back as far as I can.  The larger shoots can be treated directly with ecoplugs into cut surface.  For smaller growths, shd I insert ecoplug into the bark above the shoot?  Below it?   And is there any mileage in applying ecopods around the entire circumference (the trunk is getting on for a metre across, more at the base). If so, how high up?   Or at several levels?  

Original cut surface is not re-sprouting, nor - as far as one can see - is the trunk for a foot or so below the cut surface.   Yet.

All suggestions gratefully received!

Have a read through this^

The instructions on ecoplugs used to say that they could be applied horizontally. Ring barking might be an option. Or just keep removing the regrowth, it will die off eventually with no photosynthetic area (unless there are other limes nearby).

10 minutes with sheers once a month taking off the new growth, a long term project but that will do it.

If done by insurance contractor job not done to correct standard. And needs redoing if contract was to treat to kill. 

Other way if you want to do it your self is to drill holes in to shoots and fill with Glyphosate.
