How to Plant and Grow Miniature Roses

Gardeners with limited space can grow roses by cultivating miniature roses in containers, but they grow just as well in a garden bed. Miniature roses emerged in the 1930s as an accidental result of rose hybridizing. These perennials usually stay under 2 feet tall and respond to all the care basics of regular-size roses—deep irrigation, sunshine, and regular fertilizing. Some miniature roses have the standard upright form of many of their standard-size relatives, but they also come in climbing and cascading varieties. In addition to being beautiful and fragrant, they have no thorns and are robust rebloomers.

Miniature roses are extremely hardy, but they need extra winter protection in cold climates. Ensure the plant doesn't die back to the roots in Zone 5 and colder by burying the plant in a mound of soil.

Where to Plant Miniature Roses

Plant miniature roses outdoors in Zones 4-11. In colder areas they can be grown in containers indoors and then moved outdoors in spring. Select a location that receives 6 to 8 hours of sun a day. They can tolerate partial sun but won't bloom as profusely. These plants need rich, loamy, and well-drained soil to be at their best.

Miniature roses adapt well to flowerbed edging, front-of-the-border socializing with perennials and annuals, and low hedges.

How and When to Plant Miniature Roses

Plant miniature rose bushes much the same way you would plant full-size rose bushes. Dig a hole the same height as the pot it came in and about a foot wider. Loosen the roots after removing the plant. Spread out the roots on top of the soil that you've enhanced with organic matter. Add mulch after watering.

Like bigger roses, miniature roses do best if planted in spring.

Miniature Roses Care Tips

Miniature roses aren't fussy and require the essentials: sunlight, water, and well-draining soil.

Light

Miniature roses do best in full sun at least six to eight hours per day. Too much shade can cause them to become sparse. In addition, lots of sun helps with disease resistance.

Soil and Water

The best soil for miniature roses is loamy, rich, and well-drained. If you plant them in containers, use a light, nutrient-packed soil that drains well to avoid root rot. Water deeply and add water when the soil is dry, about 1 inch per week. Potted miniature roses, especially those grown indoors, will need more water than in the garden.

When watering miniature roses, aim the hose or watering can at the base of the plant to avoid getting the leaves and blooms wet.

Temperature and Humidity

Moderate temperatures are the best environment for miniature roses—they do best when it's around 70ºF. If it's going to be below freezing, bring any potted plants indoors to protect them from the cold. Protect plants in your garden by adding additional soil to the base of the plants and topping it with mulch.

Fertilizer

Roses need plenty of fertilizing to bloom throughout the season. A commercial rose food or all-purpose product is fine. Begin fertilizing in spring when the first leaves appear, then repeat after each abundant bloom. Consult product label instructions to determine the correct amount to use. Stop feeding your plants six to eight weeks before the first frost.

Pruning

Prune roses in late winter or early spring before new blooms appear. Cut away any dead wood and trim back around one-third of the plant to maintain its shape and encourage growth. Deadhead roses weekly to promote new growth during the season.

Potting and Repotting Miniature Roses

To pot miniature roses, use a container 6 to 8 inches deep with drainage holes. It helps to add gravel to the bottom of the pot to facilitate drainage. Use potting soil with good nutrients that promotes drainage. Keep indoor potted miniature roses where they'll get plenty of sunlight for most of the day, or they won't thrive. Also, they may need some additional humidity to stay healthy.

Pests and Problems

Keep fungal diseases like powdery mildew from infecting your miniature roses by ensuring good airflow around your plants and always watering them at the base and not from overhead. If you see signs of infestation by insects like Japanese beetles or mites, quickly spray your plants with a blast of water or insecticidal soap. If pests persist, try a chemical insecticide to minimize the damage.

How to Propagate Miniature Roses

Cuttings are the way to propagate miniature roses. Plant healthy cuttings in a moist soil and perlite mix after snipping the base for better water absorption. Don't overwater the cutting or the soil—just mist it. Set a plastic bag over the top of the cutting, but don't let it touch the cutting. Keep it indoors in a bright area without direct sunlight, After a month or two, check that the stem has grown roots by gently tugging on it to see if there's resistance. When that happens, remove the plastic bag. Once the stem is growing leaves, you can pot it or transplant it to your garden.
