A standard rose is one that grows from a single cane, much like a tree. Although standard roses can be grown in containers, they do much better when planted in the landscape. Standard roses add height to the garden and make a dramatic accent when planted in rows, lining a walkway. Care of the standard rose is much the same as that of other roses with the exception of its need to be staked.
Fill a bucket, large enough to accommodate the rose's root ball, with lukewarm water. Place the roots into the water and allow them to soak for 24 hours.
Determine where to plant the standard roses. The planting area should receive at least 6 hours of sun per day and not be located in a depression in the landscape.
Add a 3-inch layer of compost to the planting bed and mix it to a depth of 12 inches.
Dig a hole that is three times the diameter of the standard rose root ball. The depth should be the same as that in which the standard rose was previously grown. Look for a soil ring toward the lower end of the cane, as this indicates how deep it was previously planted. Use the gardening fork to lightly scrape the bottom and sides of the planting hole.
Build a mound of soil in the bottom of the hole. When the root ball is set on top of the mound, the roots should drape over the side and just barely touch the bottom of the hole. Throw a handful of bonemeal into the hole, over the mound.
Drive the stake at least 12 inches into the soil at the bottom of the hole, where it will be close to the trunk, on its sunny side. Place the standard rose into the hole and spread the roots around the soil mound. Backfill the hole halfway with soil, then fill the hole with water. When it drains, continue filling the hole with soil. Lightly pack the soil around the base of the rose with your feet.
Tie the standard rose to the stake in at least three areas: one at the top (below the canopy), one in the middle and one at the bottom portion of the cane.
Add a 3- or 4-inch layer of mulch around the base of the standard rose, keeping it 2 inches away from the plant. Spread it out 6 inches.
Water the standard rose until the soil is saturated, then water three to four times a week, to keep the soil moist, until there is new growth. Water weekly thereafter.
