Grow Miniature Roses Indoors

By Kathy Bond-Borie, Guest Columnist  

Even though the weather has turned cold and we’ve put our garden roses to bed for the winter, we don’t have to be rose-deprived until spring. 

Miniature roses adapt quite well to life indoors. They’re a bit more particular about light and humidity than some indoor flowering plants, but they will reward the extra effort with stunning flowers that come in a wide range of colors. 

For the most part, miniature roses are scaled-down versions of full-sized roses, and while they vary in many ways, all mini-roses have small, rarely fragrant flowers. Plants can range from micro-minis (5 inches or less) to 3 to 4 feet, or even larger. Flowers can be anywhere from 1/2 to 2 inches across, with a color range as broad as that for full-size roses. 

Miniature roses need plenty of bright light, such as a bright west- or south-facing window. But for repeat bloom, you’ll need the supplementary light provided by fluorescent tubes. 

Also provide some extra humidity around the plants because indoor air is typically quite dry. Set plants in a water-filled tray on a layer of pebbles, or use a room humidifier. If humidity is too low, the leaves will shrivel, turn yellow and drop. 

Here are some additional tips: 

  1. Buy new plants each season to ensure they’re free of diseases and pests. Choose varieties that are short and especially floriferous.
  2. Fertilize weekly with a fertilizer diluted to one-quarter strength. To encourage blooms, use a fertilizer with a formula high in potassium, such as 5-5-10.
  3. Watch carefully for any signs of pests. Spray whiteflies with a lightweight horticultural oil. If spider mites become a problem, wash plants thoroughly every 2 to 3 days. For a severe infestation of spider mites, strip all leaves and cut the plant back by half. Healthy new growth will emerge rapidly.
  4. When repotting, use a commercial potting mixture that contains perlite and vermiculite.
  5. When flowering has finished, place plants under fluorescent lights to encourage reblooming in about 6 weeks.
  6. After the last frost in spring, gradually acclimate plants to outdoor air. Plant them in the garden or in an outdoor container.

    I really like to have a garden but I have no space here at home and it is kind of frustrating. Thanks for this. I think I can handle this well indoors.

    I used to grow these in my home, and this inspired me to start doing so again. They are so pretty and really brighten up my home. I just have to figure out how to get my kids, dog and cats to leave it alone. Should be interesting. Thanks for the reminder!

    These mini roses are absolutely beautiful. The best thing about them is the fragrance they bring into my home. I just started growing the roses in my home last July. Since then they have really flourished. If any of you are thinking about doing this, I really suggest you jump on it!
