Growing a Miniature Rose Bush Outdoors
Miniature roses are beautiful small roses that can be grown indoors or out. They can be grown outdoors in pots or directly in the ground. Miniature rose bushes make great border plants or just add color to an otherwise dull area of your flower garden. They come in a wide variety of colors and most are long blooming. Here are a few tips on how to grow a miniature rose bush outdoors in your flower garden.
Miniature rose bushes should be planted in full sun. They need about 6 hours of sunlight daily to bloom their best. If you have previously had your rose bush indoors, you will want to gradually expose it to the sun outside. Start with a couple of hours a day. Gradually increase it’s exposure to the sun until you can plant it outside. If the leaves look like they are burning, reduce the exposure for a few days and then resume. If you are going to plant them very close to your house, you will want to plant them on the west side in order for them to get enough direct sun light each day. Do not plant them under trees or where they will be shaded by other plants. One way to tell if they are not getting enough light is If they get “leggy”, or if they stop blooming.
Once you have selected just the right spot to plant your miniature rose bush, dig the 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 with dirt. Pat down to settle the dirt and water thoroughly and apply more mulch around the base of the plant. Roses grow best with a PH balance somewhere between 6.5 to 6.8, so you may want to check your soil. If your 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 should be watered thoroughly about twice a week. You want to water them slowly to be sure that 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. If your weather is dry, you may want to lightly spray your roses and they do like moist air. If you live in a humid area, you may want to skip the misting as too much humidity can cause what is known as powdery mildew. If you do mist you may want to add some dish soap to spray bottle and mist them with this. The dish soap will help keep insect pests off your roses. The best time to water your roses is in the morning. Mid-day watering can cause the petals and leaves to burn or blister if the sun is too hot. Evening watering can also cause powdery mildew if the leaves stay wet too long.
Deadhead and Pruning
You want to removed any fading blooms from your miniature rose bush. Your plant will be more attractive and deadheading will encourage more blooms. Miniature roses need good air circulation so you also want to watch for any dead branches and remove them as well. The best time to deeply prune you plant is in fall. It is usually recommended to prune back the top one-third of the plant. To keep from damaging the stems, you need to use sharp pruning shears and cut the stems at an angle.
To “winterize” your miniature rose bush, you want to apply mulch around the base of the plant. 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. You don't want the roots to freeze. Just remember to remove some of the excess mulch once spring has sprung!
One of the most common diseases that effect miniature rose bushes is blackspot. Be sure that your plant is in an area with good drainage. If it stays too damp or it does not get enough air circulation it can cause blackspot to develop on the leaves. Blackspot is a fungus that can spread throughout your plant quickly. Remove the leaves affected and spray with a fungicide made for blackspot. Most home and garden centers will have a fungicide specifically designed for blackspot.
Another common disease for roses is powdery mildew. The first sign will be the crinkling of young leaves. After that you will see a white powdery substance begin to form. This usually occurs when the leaves are staying to moist. Be sure you 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 also.
Miniature rose bushes are beautiful plants and they are not difficult to grow. Watch your plant and it will tell you what it needs. Miniature roses can add gorgeous color to your flower garden for years to come. I hope my tips here have been helpful in growing your miniature rose bush outdoors.

HI, I left my mini roses outside all winter in the pot. They told me at the store that they will grow back, but now I don't know, the stems seems to be all dried up. Do you think they will grow back? or do they still have a chance if I keep them in the sun?

Hi Peggy! I have found that mine do better in less sun than the full size ones. Thank you for stopping by and the pin! Have a great day! :)
Peggy Woods from Houston, Texas on May 22, 2014:
I have regular rose bushes growing outdoors but have never tried the miniature ones. It sounds like they pretty much need the same type of care that the larger varieties do. Pinning this to my gardening board.

Hello dirt farmer! I do love my miniature rose bushes. I did manage to over-water one this year, yikes! I think I can save it. I do plan on getting more. I love the coral color too and that is definitely one I plan to purchase. Thank you for stopping in and commenting, it is always appreciated! Have a beautiful day! :)
Jill Spencer from United States on August 29, 2012:
I have two miniature rose bushes growing outside--one red and the other a grafted plant with red, pink and white blooms. Really appreciate the growing tips! And I love colors of the ones you spotlighted on Ebay, especially the coral.

Hello furniturez! I love roses too and miniature roses are just the perfect size for so many places in your yard. I'm sure yours will do well there in Washington. Mine are struggling as we have had temperatures of up to 114 degrees this year. It's hard on my little roses! Thank you for stoppin in, reading and commenting, it is always appreciated!

I'm certainly going to put this into practice! I love roses :)

I planted a miniature rose right outside in the garden last fall since it wasn't doing so well in the pot. It is gorgeous and given me quite large and beautiful roses. It is in a sunny location and has great drainage...otherwise other than watering and pruning off old blooms not much care needed!

Hello MizBejabbers! If the heat in Arkansas is like it is here in Southern Oklahoma, sometimes it's hard to get anything to live. I have moved my miniature rose bushes to a place where they get morning and a little afternoon sun. I have taken them out of the hottest afternoon sun. It was just too much for them! Last year we had over 100 degree weather for about 30 days in a row, with NO rain! Try to keep the soil just damp and I like to water in the evening. "They" say not to, but this seems to let the roots enjoy the cool water longer and the ground still dries out enough to avoid the blackspot and powdery mildew, so far. I hope to try the miniature roses again. Thank you for stopping in, commenting and voting on my hub. It is always appreciated. Have a beautiful day!

I've tried planting miniature roses outside and they have always died. I want to follow your instructions to see if I can get one to live. You didn't say when to plant, but I assume it would be spring. We live in Zone 8 kind of on the borderline of Zone 7, so it should be ok. Being in a humid zone, we have a lot of trouble with blackspot and powdery mildew and we really have to stay after the roses. Thanks for the advice. Voted up.

Hi there Deckgardener. If you have lots of buds, it should be getting plenty of sunlight. I'm not sure why you have thinning leaves either. Look on the underneath of the leaves and be sure there are not some type of little buggy guys there. I hope you figure it out, I haven't had a problem with that. Thank you for stopping in and commenting, it is always appreciated. Have a great day! :)

I have had my rose bushes for 3 years but for they are now thin with leaves. They are potted and live outside which is their normal life. Tons of buds.... not sure why the thinning leaves???

I have one mini rosebush that was here when we moved here. I have not babied it much, and it still produces some nice flowers every summer. I do know that roses LOVE horse manure mixed with straw. That's what we put on all my flowerbeds every spring. We get it for free from my husband's parents and it serves as mulch and fertilizer all summer.
