Can Miniature Roses Be Planted Outside?

If you’re looking to add a pop of color and beauty to your garden, miniature roses are a great option. They come in a wide range of colors and have a long blooming season.

They are perfect for border plants and can add some much-needed charm to an otherwise dull area of your garden. Growing miniature roses outside can be a fun and rewarding experience.

Sunlight Requirements

Miniature rose bushes need at least six hours of direct sunlight daily to bloom their best. If you’re moving indoor miniature roses outside, it’s important to gradually expose them to the sun.

Start with a couple of hours a day and gradually increase their exposure to the sun until you can plant them outside. When selecting a spot to plant your miniature roses, make sure it receives enough direct sunlight each day.

Avoid planting them under trees or in spots where they will be shaded by other plants. If you’re planting them close to your house, plant them on the west side to ensure they get enough sun.

Planting Instructions

To plant your miniature rose bush, dig a hole approximately 4 inches deeper than the pot the rose bush came in and about 6 inches wider.

Layer some mulch, such as peat moss, at the bottom of the hole to improve drainage. Remove the rose bush from the pot and loosen the roots.

Place the bush in the hole and surround it with dirt. Pat down to settle the dirt. Water thoroughly and apply more mulch around the base of the plant.

Soil pH

It’s important to maintain the ideal pH balance for your miniature rose bushes. They grow best with a pH balance somewhere between 6.5 to 6.8.

You can test your soil to check the pH level. If the pH is too low, you can add a commercial fertilizer with ammonium sulfate. If the pH is too high, add a little lime to the soil.


Miniature rose bushes need to be watered thoroughly about twice a week. You want to water them slowly to ensure the water gets all the way down to the bottom of the roots.

Be sure the area allows the water to drain well so the roots don’t stay too wet, as they can rot. The best time to water your roses is in the morning.

Midday watering can cause the petals and leaves to burn or blister if the sun is too hot. Evening watering can cause powdery mildew if the leaves stay wet too long.

Deadheading and Pruning

To keep your miniature rose bushes looking their best, you’ll want to deadhead them regularly.

Deadheading means removing the fading blooms from your plant, which encourages more blooms and keeps your plant looking more attractive. Miniature roses also need good air circulation, so watch for dead branches and remove them as well.

Pruning your miniature rose bushes is also important for their growth and appearance. The best time to deeply prune your plant is in the fall. It is usually recommended to prune back the top one-third of the plant. To avoid damaging the stems, you need to use sharp pruning shears and cut the stems at an angle.


To prepare your miniature rose bushes for winter, it’s important to protect their roots from freezing. In zones 6 and above, applying a 1-inch layer of mulch around the base of the plant should suffice.

In zones 6 and below, you may want to put some type of edging around the plant and put several inches of mulch around it.

Identifying Common Diseases

Like all plants, miniature rose bushes can be susceptible to diseases. Two of the most common diseases that affect them are blackspot and powdery mildew.

Blackspot is a fungus that can spread quickly throughout your plant, causing dark spots to appear on the surface of the leaves. To prevent blackspot, be sure that your plant is in an area with good drainage.

If it stays too damp or if it doesn’t get enough air circulation, it can cause blackspot to develop on the leaves. To treat it, remove the affected leaves and spray the plant with a fungicide made for blackspot.

Powdery mildew is another common disease that affects miniature rose bushes. The first sign of powdery mildew will be the crinkling of young leaves. After that, you will see a white powdery substance begin to form. This mildew usually occurs when the leaves are staying too moist.

To prevent powdery mildew, make sure your miniature rose bush has enough air circulation and do not water your rose bush in the evenings. You can buy a fungicidal spray for powdery mildew at your home and garden center.
