My thought is that it is way too close to the foundation, regardless, and you want to either kill it or dig it up and move it. It or anything taller that 1 1/2" feet and wider than 6" will get too large for the spot and will rub against the house with potential for damaging siding. It won't ever have a nice form - it will always be lopsided due to its position. It is easy to start from cuttings and they are usually relatively easy to find at big box stores and nurseries. Why would you want to keep it in that spot?

boy was i right on its placement ...

at 28 ... i am glad you took action .. and want to observe reaction ... by the plant i mean ...

this is how i learned just about everything.. as there was no web back in the day ...

with no insult to the root mass ... you will probably be amazed at its hyper aggressive response ...

my other theory.. was the utilities were in back of it... are they right ont he other side of that fence???? i see the hose .. so i know the spigot is near ..

i am not sure i would have left the two tallest .. and i would shorten the ones.. thaw lean into the house ...

perhaps you can move it in fall .... in the next cool season ... but by then.. you might just decide in removal ... since it will already be out of the ground ...

i never worry about intentionally killing a plant... as i usually replace such.. with two or three... mother earth plus 2 ...
