Thank you, and for varied advise so far.
Some of those canes on the ramblers have already grown 10 ft! Since I am training (staking) them over the boulders (not seen in pics) I WAS wondering about how hardy they might be their first year here.
My babies!
I can't see me trenching them as this is not my own garden and is suppose to be an easy care estate rental place! I was though kinda wondering if I needed to cut the long canes back.
So, am I safe to say that I should bring in several bags of compost / humus / manure / pine bark mulch (which I see as adding no nutrients) and put them around the base of the plant. And do nothing about burlap (please, please, please!) around the Knockouts?
Just over the driveway, 2 knockouts got knocked out 2 years ago. They are barely lingering on. But then, I did NOTHING to help them over the winter. Same ocean/windy conditions. And they want me to replace all 16 roses there next year. Varied, supposedly hardy varieties that I planted a dozen years ago. Bonica, Carefree Beauty, etc.
Thank you for your help.
