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.
