Should I cut down these perrenials every year? I have a number of strange plants this year in my flower...

I have a number of strange plants this year in my flower gardens. I normally work beside annuals and now have perrenials as the plating every year get old. Do I need to cut fund perrenials in the Fall, and if so, how much? I have lavender bushes, asiatic lillies, hastas, ruber plants, and baby's breath to term the bulk.
I would not cut back your lavender. I usually linger until spring to do most of my cutting back on other things.


Perennials will die off later you can cut them back. If you don't do anything they will eventually freeze off and you can verbs up your beds then. Perennials come subsidise every year from the root. This is called the mother plant. After they get bigger you can verbs up the whole plant in impulsive spring before it gets big or the go down and divide it for more. some of your blooming plant may have had seed that will fall to the ground and they will also come back within the spring. Some people do, I do not because by the time they are ready to be in motion to seed it's late within the year. I just leave them as is and if you hold cold winters the plant helps to protect the roots.
That is on just the flowers you name, some perennials I do cut back especially if it's a vining plant.
Answers:    Some perennials can be cut down I cut my hostas and Lillie's. My baby's breath is a bush and I don't cut it back. My rule is If the frost kills it and falls over to the ground I cut it. May I give some of your perennials make good dried flowers the lavender would be pretty as a dried flower I usually tie something arround a bunch of it and put surrounded by baskets ,vases my porch , door wreath or so much more.
