How is it best to divide a clump of Nepeta Six Hills Giant? (I'm a nervous novice gardener!)

Hi Jim ,

Im having the same issue. My plants border a patio and now look out of control as they are laying across it !

Any suggestions for how best to curtail the growth of a number of clumps of my Nepeta Hills Giant? They are in their second year and are tending to overpower neighbouring plants. I`m a novice gardener by the way.,

It does need to be well drained, did you add plenty of grit to the soil at planting time? I would be inclined to try rescuing it by carefully lifting and incorporating plenty if grit into the planting hole, with all the wet weather we have had, it doesn't like to sit in water.
It come from Italy and grows best in full sun.
You might like to add a photo , it may have been rolled on by cats!

I should post a photo but for now I'm wondering if anyone has had a problem with Nepeta Six Hill's - plants went in only a few weeks ago and were healthy - now leaves are going red - no new growth since they went in - altogether poorly looking - not the bushy plants we expect them to become - of which there are plenty specimens in the same garden only a few feet away. Any ideas welcome - thanks.
