How to Grow Miniature Roses Inside

Place a 6- to 8-inch deep and 8-inch wide pot near a west- or south-facing window, or a spot exposed to four to six hours of direct sunlight every day. Make sure the temperature of the selected site remains between 70 and 75 degrees Fahrenheit during the day, and no lower than 60 degrees Fahrenheit at night.

Pour quality soil amended with organic matter such as compost or manure to provide the miniature roses essential nutrients. Dig a hole in the center of the pot with a hand trowel and plant the rose into it. Backfill the hole and tamp the soil to remove pockets of trapped air.

Irrigate the miniature rose when the top 1 inch of soil feels dry. Provide a slow, steady stream of water until excess flows out through the drainage holes at the bottom of the container. Avoid wetting the foliage that increases chances of fungal diseases.

Fertilize the miniature rose with a slow-release or rose fertilizer at half the recommended strength every three to four weeks from spring until midsummer. Avoid fertilizing the mini rose after end August so it prepares for the winter.

Clip off spent, dry or damaged leaves or blooms to encourage fresh growth on the miniature rose. Using sharp, sterilized clippers, form a 45-degree cut to sever the damaged section from the remaining stem. Collect debris and fallen leaves and clippings and discard.

Treat pests such as aphids, spider mites and scale on the plant with a jet of water from a hose, or use an insecticidal spray to treat large infestations. Alternatively, mix 1 to 2 tbsp. dishwashing soap in 1 gallon of water and spray over the pest infestations.
