Roses are a joy to grow and have around, whether they be in an outdoor rose garden, indoors on a sun porch, or growing happily in a greenhouse. Because most greenhouses are heated during the winter, roses can continuously grow throughout the year without any interruptions. Greenhouses provide roses with protection from the weather such as high winds and torrential rains that can easily break and destroy a healthy rose plant. By ensuring a few simple needs are met, roses can easily be cultivated in your own backyard greenhouse.
Place the rose plants into the greenhouse so they have efficient lighting. Roses enjoy the warmth and the sun. If you have more then one rose plant, organize the roses so they each receive full sunlight for most of the day, and are not shaded by each other or other plants.
Water the roses as needed. Generally, a greenhouse will retain high humidity, so daily watering isn't necessary. Ensuring that the soil around the roses base is constantly moist to the touch (not soaked) will do the trick.
Fertilize the roses every other week, using a rose food designed to help maintain proper nutrients. Follow the instructions for dosage that come with the rose food for best results.
Apply an insecticide or fungicide designed for roses to fight pest infestations.
Prune the rose throughout the year to do away with any dead or overgrown foliage, using sharp, clean pruning shears.
