If you’re planting a standard rose or tree rose, you’ll need to stake it for the first year. Choose a stake that is 2 feet longer than the trunk or stem of the standard.
After digging the hole, but before placing the rose in it, set the stake into the ground to the side of the hole toward the prevailing wind. Drive the stake about 2 feet into the ground. Once you’ve planted the rose, check that the top of the stake is below the bud union.
With soft plastic tape, tie the stem to the stake near the top and about halfway down the trunk. Use a figure-8 pattern for the ties to prevent the stake from rubbing on the stem.
If you’re planting a climber, you’ll need to provide support. This can be a fence, trellis, arbor, post, wall, or even tree. You can tie a rose to an open support system, such as a trellis or fence, with soft plastic ties (be sure to keep the ties loose).
Also be sure the structure is strong enough to hold the weight of the grown plant. Trellises, in particular, can be fairly lightweight; you may need to attach a trellis to a wall-framing system or posts. If you don’t, be sure to leave some space between the trellis and adjoining surface to let air circulate. Solid surfaces such as walls will need support wires added for attachment of the canes.
For a climber, make some adjustments to the basic planting instructions (see Rose-Planting Basics). If your plant is a rambler–a vigorous climber that can easily grow to the top of a house or tree–cut it back to almost ground level to encourage new shoots from the base. Don’t cut back other types of roses. Make your planting hole about 1 1/2 feet away from your plant’s support structure. Set the plant in the hole at a 45-degree angle and lean the canes toward the support. If the lowest level of the support system is above the tops of the new canes, use temporary stakes to support the canes until they reach the permanent support.
Miniature roses should be set out as you would a regular container rose. If you’re planting a mini rose, give it time to acclimate to outdoor conditions by placing it outside in a sheltered spot for a few hours every day for several days. Set both miniature roses and mini roses slightly deeper in the soil than they were growing in their pots, and water frequently as their roots are shallow.
