I have a neighbor who used to own a townhouse with a courtyard. The rules disallowed planting into the soil so she decorated her outdoor space with colorful potted plants.
I also have a friend who lives in a ground floor apartment. The management will not let her plant the flowers she loves so dearly in the ground beneath her windows, but they do not mind her placing containers there and on the concrete walk beside her door.
Miniature roses adapt better to pot culture than any other type and need only a very bright windowsill to thrive. There are 2 ways to grow mini roses as houseplants:
If you have a bright enough location, you can grow the roses indoors year round. Roses need 6-8 hours of direct sun (or the fluorescent equivalent thereof) each day in order to maintain healthy growth and to bloom.
If your home is too dark and you do not wish to supplement with artificial light, keep the plants outdoors most of the time.
Bring them in when their flower buds swell enough to reveal the color of the blooms. Return the roses to their outside location after the petals fall.
For the short time the plants will spend indoors, they can cope with lower light conditions.
Hybrid Tea roses
grown in containers can be moved into a greenhouse for winter bloom. You'll be cutting roses from your potted plants when your rose bushes in the ground are still dormant.
The Best Container Garden Roses
When growing roses in containers, you will want to choose varieties which do not grow too vigorously. Vigor is a desirable quality in a rose that must jockey for space with other plants in a perennial border, less so in a potted rose.
Hanging baskets call for a rose with a weeping growth habit like, 'Sweet Chariot' shown here.
Containers which will be used to fill gaps in a flower bed may house lanky Hybrid Tea roses as their naked knees will be hidden by the surrounding foliage.
If the pots will be prominently positioned, compact-growing types will be better appreciated. Other features to look for include, healthy foliage which is abundantly produced and good flower production.
When growing roses in containers, you want shapely plants that look good even during those brief periods between bloom flushes.
The biggest challenge you will face when growing roses in containers outdoors is keeping them properly watered. During hot weather, pots setting in full sun can quickly dehydrate.
Roses are not xeric plants. They require even moisture at their roots. Repeated exposure to drought will weaken them.
If going out to water the pots each day is an enjoyable pastime for you, this will not be a problem. If not, my advice would be to group the pots together and run a drip irrigation line through them.
Drip irrigation hoses are thin and black. They can be easily hidden amongst the foliage. I also like drip irrigation for growing roses in containers because it is water wise. You can arrange for the water to go precisely where you want it to.
None is wasted.
Add an inexpensive timer to the set up and your hydration problem is solved.
