First popular in the early 1800s as a parlor plant, miniature roses are a unique variety of rose that has been deliberately bred to grow to only 1-2 feet when mature. This tiny version of the ever-popular rose bush makes a wonderful houseplant.
Miniature roses thrive in bright sunlight and will do best with 6-8 hours of direct sunlight per day. For this reason, place your miniature roses close to a south-facing window. In the height of summer, a south-facing window can get very warm and so move them farther from the window to limit the heat exposure for the plant. It’s generally a good idea to rotate your miniature rose every 1-2 weeks, so all areas of the plant are receiving similar amounts of light and growing symmetrically.
Miniature roses require frequent watering, but they can be susceptible to root rot and fungal infections, so you have to be mindful to avoid allowing them to sit directly in water. Allow the soil to dry out between watering to ensure you avoid these problems. Test the soil with your finger prior to watering. If you can put your finger one inch into the soil and it’s dry, it’s time to water. Avoid allowing water to touch the leaves or the blossoms as this can cause damage to the plant. Water your miniature rose until the water runs out of the bottom of the planter.
Choose a high-quality potting soil mix that has perlite and compost incorporated into the mix. The perlite is an organic lava rock that will improve drainage and the compost is decaying organic matter that will feed your miniature roses and encourage more growth.
Fertilizing your miniature rose on a regular basis through the warmer months of the year, is recommended. This will encourage the growth of new foliage and flowers and help your miniature rose to stay healthy. I tend to use a water-soluble fertilizer and dilute it to approximately half the suggested strength.
Miniature roses thrive on high humidity. A great way to do this is to place your miniature rose planter on a tray that is filled with pebbles and has water partially covering the pebbles. Make sure the base of the pot doesn’t sit in the water though. The water in the tray will evaporate slowly, increasing the local humidity around the rose plant.
