If you plant roses correctly in late autumn, they will successfully survive the winter, returning healthy, vigorous, and full of blooms the following year.
Autumn is an excellent time to transplant any roses that are in the wrong spot. You can also plant new ones, as they will have enough time to root before winter.
Roses are available as container-grown plants or as bare-root plants from November to March.
Learn how to plant a bare-root rose in late autumn.
Dig a hole for the rose in the ground that is as deep as a garden spade and the same width. Set the soil aside on one side of the hole.
Loosen the bottom of the hole for planting the rose in late autumn and add a handful of granular fertilizer, such as granular chicken manure. Slightly compact the bottom of the hole with your foot.
Place the bare-root rose in position and use a stake placed across the top of the hole to gauge the final soil level around the plant. Aim to position the base of the stems slightly below this level.
Add a spadeful of compost to the soil you removed from the hole and mix it in.
Use this mixture to fill in around the roots of the rose, compacting it in layers with your heel.
Once the hole is filled, add a layer of well-rotted compost mulch to the soil surface to retain moisture while planting the rose in late autumn, then water the rose thoroughly.
