Packed roses are somehow similar to the bare-root roses except that they are having some soil around their roots. You can choose to plant them with or without the package as long as this is made of paper, because this will decompose in the soil and will provoke less shock when planting.
Container-grown roses have the best chance to survive and they can be planted at any time of the year as long as the weather conditions are suitable. You can chose to keep them outdoor in their container but take care to not risk exposing them to prolonged frost as the roots in the containers may suffer some damage in very cold conditions.
There are different ways to plant roses: plant them in a row to form a hedge, plant them close together to form a bush, or plant as a single rose for a focal point. When planting roses for a hedge you have to consider a 1-1,2 m distance between them so that, when mature, the branches intermingle to form an effective screen. For a denser hedge plant roses in a staggered formation in two rows that are 45-60 cm apart.
Planting a climbing rose or a rambler is a bit different because you have to plant it against a wall or a fence at an angle of about 45 degrees so that the shoots reach the lowest support wire. Use canes to guide the shorter shoots towards the wires. Tie all the shoots to the canes or wires with plastic straps. Take care not to tighten the straps too much around the rose’s stamps because they need space to grow. You can choose to plant a rambler rose by a tree but is essential to choose a vigorous tree because many of ramblers as they grow are achieving a considerable weight.
Tree-like roses need to be plant no deeper than the soil mark to keep suckering to a minimum. This kind of roses need a stake placed on the side of the prevailing wind, to support it. Position the stake in the hole so that the rose stem will be in the center. Drive the stake into the ground just to make sure that the top is just bellow the head of the rose. Place the rose in the hole, feel the hole with soil, firm well and water. Use a rose tie just below the head of the rose and another one halfway up the stem to attach the rose to the stake.
In temperate climates all roses need protection if is a bad winter. Pack the crowns of tree-like roses with straw or bracken, loosely tied in place with twine. If is a very bad winter protect the roots of the tree-like roses and bush roses also by covering them with straw or spruce fir branches. Do not use plastic folio because of the danger of rotting. Remove the protection only in spring.
