We recommend planting potted roses as soon as possible. However, if you are unable to plant immediately, roses can be kept in their pots quite happily for two months or more, as long as they are watered appropriately. Potted roses should not be allowed to dry out. A full, regular watering is better than just small amounts daily. The need for water is dependent on the weather and potting mix. For that reason we suggest contacting the garden centre where you bought the rose for a local recommendation.
