Miniature roses can grow in window boxes as well as standard pots.

Pot Size for a Miniature Rose

by Shala Munroe

Miniature roses (Rosa spp.) need basically the same type of treatment as regular roses, only you can use a smaller container. The shorter plant height and smaller, more lightweight blooms makes miniature roses ideal candidates for container gardening. Buying the right size pot keeps the plants from being root bound and lets them grow to their full potential.

Miniature Rose Size

Miniature roses look just like their name implies: like small versions of regular roses. Some varieties are as small as 6 inches tall, while some grow between 18 and 36 inches tall. Climbing vines might reach 5 feet tall. The roses themselves can't be larger than 1 1/2 inches in diameter to be considered miniature.

Pot Size for Young Plants

When you buy new miniature roses or propagate from cuttings, a pot with a 2-inch diameter typically is sufficient to allow the root systems to begin developing. They shouldn't stay in these small pots for long, however. By the time you see buds developing, you should move the miniature roses to a larger pot, such as a 1-gallon container. This gives the roots plenty of room to grow and spread out, ensuring a strong and healthy plant.

Pot Size for Mature Plants

After actively growing for about six months, many miniature roses are ready to move to new, larger homes. It's best to move the plants before they become root bound. If you notice water running out of the pot as you pour water in or the pot feels lighter than it should, it's definitely time to transplant the miniature rose so its roots can spread out. Smaller varieties grow well in 4- to 5-gallon pots, while taller varieties need a 7-gallon pot.

Container Watering

Roses need plenty of water to thrive, and those grown in containers need water more often than those planted in the ground. Miniature roses need consistently moist but not wet soil, so the containers you choose should have adequate drainage. Containers don't keep the soil at as constant a temperature, and pot materials such as terra cotta or wood allow necessary moisture to escape from the soil; glazed ceramic or plastic pots might be a better choice to help retain moisture. In hot weather, miniature roses might need water as often as twice a day, although watering every other day is usually sufficient in moderate temperatures.
