Taking proper care of your rose bushes once they begin to set buds ensures healthy blooming all season long. A healthy rose plant produces buds more abundantly and may flower for longer periods of time. To encourage budding, constant maintenance is required. Poor pruning practices or the lack of fertilization can led to poor flowering the following year. While roses do require maintenance, it isn't terribly time consuming and the rewards are worth the effort.
Keep the soil moist at all times, especially spring in summer as the plant prepares to flower and is flowering. Water deeply once weekly until the soil is moist to a 1 foot depth.
Fertilize with a rose fertilizer after the last spring frost; continue fertilizing every six weeks until the end of July to encourage healthy buds and blooming. Use 1 heaping tbsp. of fertilizer per plant.
Cut blooms for vase displays carefully. Use clean shears and leave at least two leaves per stem on the rose bush. This allows the stems to collect the nutrients needed for next year's budding.
Prune off all dead wood and diseased branches in fall with sharp shears. Remove winter damaged and dead branches in spring.
Mulch around plants with straw, compost or leaf mould before the first hard freeze in late autumn. Make a 12-inch mound of the mulch around the base of each rose bushes.
