That IS quite the project!
I’m a rose nut, so I’m sure we’ll have lots to talk about! :)
There were seven rose bushes here when we bought the house. Four of them were five foot wide and six foot tall overgrown but blooming like crazy. They bloomed through Christmas and we’re blooming in late summer when we first saw the house. I am in the process of pruning them back with a goal to get about 60% pruned out. There is some disease that I may be able to treat if I get the plants healthy. I am getting all the mulch and debris out from below them and sprayed them with fungicide and dormant oil when we got here in December.
Pruning is difficult as I have hand, arm and leg skin that punctures and bruises with the slightest touch due to chemo. So I get covered up with leather guards in addition to heavy gloves.
I am determined to get these roses restored as they hold over a hundred and fifty blooms at any one time. (Actual count the week before Christmas)
Roses are the plant where I have the least experience so I am always open to advice.
