I'd like to buy my daughter's childminder a rose as a thank you / leaving present and have found one with my daughter's name (childminder loves roses). However she's not leaving till Sept, just before she starts school. Do I buy a 4 ltr potted bush now, take photos of the roses, and look after it till Sept when presumably it won't look that special? How would I take care of it? Or is buying closer to Sept advisable? Are they even available then? She does keep a lot of her roses in pots.
