Bare root
plants are the best way to go.
plants grown in pots get used to the pots, they get used to the soil that's in the pots, and they get used to being watered every day. And, when they are sent off to a HOme Depot or Wal Mart, they sit around and get stressed before you get them.
Don't amend the soil too much...the old advice about u sing half and half old soil and amendments can lead to problems after 2 or 3 years of growth...but do dig the hole at least twice as big as you need, firm the soil in the bottom of the hole and yes, as Comfrey says, wiht
roses, build a mound in the bottom,and spread the roots over this. Plenty of bone meal in the bottom, a little compost or rotted manure.
plant as soon as you can.
If this sounds like a lot of care, don't worry, bare-root
plants do VERY well as long as they don't leaf out before you can get them planted, and you remember to water them in well and then weekly after they leaf out.
excellent advice.
