Ohhh Terri, prepare to do some major pampering for the roses. They are so worth it!! When the time comes, I can tell you which ones have done well in my gardens.
I've learned to start spraying for black spot just when the leaves get ready to sprout and continue to spray all summer. Epsom salt, Aggrand's fertilizer, bone meal and kelp go into their root area every three weeks. Grub control goes into the ground in April and August. Water every day.....roots only in weather over 80 degrees.....etc. etc
