Remember that all new roses that I put in are now replacements. There are many advantages in this system of container planting and only a few disadvantages. Container planting can be done at anytime, regardless of weather and soil conditions. Ideal potting soil mixture can be made for maximum root and plant growth. Pots can be moved into a garage or protected area in case of freezing weather after late fall or early spring planting.
Roses get off to a quicker start in the spring due to root zone being warmer above ground.
Normally will get more growth the first season because of all of the above. I can evaluate the variety and bush for the first season without going to the labor and hard work of planting it in the ground. Rose bush does not need to be removed from biodegradable pot before planting in the ground and the well-established roots are not disturbed. Some extra work in planting in the ground if you decide after evaluation to keep the potted rose bush-although the improved growth should offset this. Will need to water more frequently than bushes that have been planted in the ground.
