Miniature roses are one of those favorite plants that many people buy to add color to their day. While they can be kept inside, they can difficult to manage. Below are some tips to help your miniature rose survive the indoor climate and bloom again.
Miniature roses require a lot of sunlight. This means they need to receive at least six hours of direct sunlight per day. To achieve this, place them on a south or west facing window. Turn them often to achieve even growth around the plant. Also, miniature roses require constant monitoring when it comes to soil moisture and depending on the indoor environment may need a daily dose of water. But before you just pour water onto the soil, check the moisture level with your finger. If you stick your finger in the soil and it comes up clean, then your plant needs to be watered. If it comes up with soil on it, then the soil moisture is fine.
Also, miniature roses are very susceptible to fungal problems. To avoid this, only water in the morning or early afternoon and do not let the plant sit in water.
As your rose blooms, remove the spent flowers. To do this, count down two leaf sections or nodes and cut the stem at an angle.
In the spring, place your miniature rose outside but bring it in if there is a chance of frost. Place it in a shady area and then gradually move it to a sunny location. This process is called hardening off.
After the danger of frost has passed or your local frost-free date has come and gone, you can leave your miniature rose outside. But continue to monitor the soil moisture. Also, this is the time to shape up your rose bush before new growth begins to appear.
Once the new growth begins to appear, feed your miniature rose with a fertilizer formulation of 5-10-5 or any formula’s whose middle number is larger than the rest. Continue this through the summer months.
Prior to the first frost, one will need to bring their rose indoors but do not put them in a warm room. They will need to go dominant, which is triggered by the exposure to cold. To do this move them to a garage or place them on a cold windowsill. Let your plant remain there until the early spring. While doing this step seems counterproductive, it allows the plant to rest and prepare for the next round of blooms.
Your miniature rose will need to be replanted at least once a year. This is better done in the early spring before new growth appears. To do this, choose a container that is wider at the top then the bottom and sterilize it. Then place a layer of drainage material and fill half way up with a bagged soil that contains compost, perlite, and peat moss.
Many commercially sold miniature roses contain more than one plant per container. If you find that you have more than one plant, prepare to plant each plant in its own container.
Once the plants have been separated, shake the old soil off the roots and place in the new container. Fill in with the remaining soil and water in. If the soil settles below the root ball add more soil.
After you have transplanted, you can then prune your rose to improve the shape and to remove any dead or diseased plant material.
While growing miniature roses indoors can be a challenge, they are worth the effort and the hints described above will help you succeed in growing your own indoor rose garden.
