The Q&A Archives: Miniature roses House plants

Question: I bought a container with three different plants,one is a miniature rose which is very dry and all the leaves are falling off.I keep the soil moist and the other plants are healthy, can you help?

Answer: When mini-roses are kept too hot or the air is too dry, they develop some brown leaves, usually toward the ends of branches.

Here are some tips for growing miniature roses:

To bloom and stay healthy, they need bright light all day long and several hours of direct sunlight. If needed, supplement what is naturally available with artificial full-spectrum lights.

It is important to keep the soil evenly moist while they are actively growing and blooming. After they have finished their bloom cycle, water can be cut back and the soil allowed to dry slightly between watering.

Miniature roses will grow best in a cool location, especially during the winter. If temperatures exceed 75? in the summer, be sure to increase the humidity.

They like high humidity, but avoid wetting the foliage or flowers. To increase the moisture in the air, use a humidity tray or a humidifier.

During the spring and summer, fertilize miniature roses every 2 weeks with a water soluble food. During the fall and winter, cut back to once a month with a half strength solution.

Miniature roses grow best in a quality, peat-based potting soil.

If you are keeping them over from year to year, repot them in the spring. They do like to be potbound, so be sure not to increase the pot size too much.

While they don't like leafshine products, they do appreciate an occasional shower to remove dust from the leaves. Prune out the flowers as they begin to fade so the plant will put its energy into producing more flowers instead of forming rose hips.

Like their outdoor cousins, miniature roses go through a blooming cycle and a rest cycle each season. They naturally bloom from late spring through early fall. After they have finished blooming for the season, they will need a rest period of several months before they will bloom again. Ideally, during this rest period mini-roses should be kept as cool as possible without freezing. After resting, prune them back to encourage compact new growth.

Hope this information helps you grow outstanding miniature roses!
