Tips for Growing Beautiful Blooms at Home
Roses grow wild in Colorado and are well adapted to our soil and weather. Although the wild rose can be extremely invasive and is not recommended for the home gardener, cultivars grow very well here and many bloom throughout the summer. Tree roses, climbers, hardy shrubs, hybrid teas: Many of these beautiful roses are grafted onto hardy rootstock for use in local gardens. It is important to note the graft junction when planting (usually a swollen area on the stem)—this should not be buried underground.
Unless they are bare root, wait until after Mother’s Day to plant roses. If the temperature drops too low, tender shoots may freeze. This year Dwyer Greens brought in 130 roses on March 12, potted them up the same day, and placed them in a greenhouse to root in. Temperatures were kept around 45 degrees at night so as not to ‘push’ them too fast. They are grown cool for about a month, but once they have broken dormancy and started to grow, the greenhouse temperature is raised to 65 degrees at night.
When planting roses be sure to amend your soil with high-quality compost. The hole you dig for your roses should be twice as wide as the root ball, but at the same depth. And don’t forget: Roses like to be fed! They produce more blooms with regular feeding.
