Question: When should I plant new roses?

Answer: Roses can be planted in February, while the plants are dormant. They can also be bought and planted in April and May (and later) while they’re in bud and bloom. Buy modern roses in 2-gallon pots (or larger) to ensure that you have well-developed root systems. Antique roses are grown from cuttings, so 1-gallon plants will do quite well.
