How to Grow Roses in Raised Beds
Raised beds are excellent for roses because they guarantee the sharp drainage roses need. Fill them with a rich, free-draining soil mix, space plants for airflow, and water more attentively, since raised beds dry out faster.
Roses hate wet feet, and a raised bed solves drainage problems at a stroke — which is why they excel in heavy clay or high-rainfall gardens. Build the bed at least twelve to eighteen inches deep and fill it with a fertile, free-draining mix of good topsoil and plenty of compost.
Give each rose room for air to move around it, mulch to conserve moisture, and water attentively: the same sharp drainage that keeps roots healthy also means raised beds dry out faster than open ground, especially in summer. Otherwise, grow them exactly as you would in a border — full sun, regular feeding, and seasonal pruning.
