If you're thinking of adding a rose to your garden, you might want to consider a bare root plant. Bare root roses offer several advantages including a greater number of varieties and choices than roses already growing in pots. Because they are set out at the beginning of the growing season, bare root plants easily adapt to your specific growing conditions. They are dormant and don't have any vegetation so they aren't vulnerable to late frost like potted roses that have already begun their growth cycle. Here are step-by-step instructions for how to plant bare root roses.
What Are Bare Root Roses?
When to Plant Bare Root Roses
The planting time for bare root roses can be any time between January and May depending on your growing zone. Roses are planted in late winter in warmer climates and n the early spring in colder regions.
Plant after the danger of frost has passed and temperatures range between 40 and 60 degrees Fahrenheit. This gives the plant time to settle and form roots before summer heat sets in. The window for planting roses is rather wide, but they should not be planted when the ground is waterlogged or during a drought.
Storing Bare Root Roses Before Planting
Purchase bare root roses as close as possible to planting time. If you do need to store the plants for more than several days, make sure the roots don’t dry out. Open the plastic wrapping, spray the roots with water daily, and cover them up again. You can Keep them in a cool, dark place for up to one week.
Before Getting Started
Pick a suitable planting site. Roses need sun, at least 4 to 6 hours every day. In hot climates, some afternoon shade can be beneficial. Find a location where the rose does not have to compete with other plants for sunlight, nutrients, or water. Consider the mature growth and give both the above ground plant and its root system ample space.
Roses are prone to numerous pests and diseases that can remain in the soil so don’t plant a rose in the same location where a previous rose has died.
Equipment / Tools
- Spade or shovel
- Work gloves
- Watering can
- Bone meal
- Bare root rose plant
- Compost or well-rotted manure (optional)
Inspect the Plant
Once you receive your bare root rose, remove it from the packaging and inspect it closely. Remove any roots or canes that are broken, injured, or soft, which indicates rot.
Soak the Roots
Place it in a bucket with lukewarm tap water so that the roots (not the canes) are sitting in water. Soak the roots for at least two hours but not longer than 24 hours.
Dig a Planting Hole
Remove any weeds from the planting site. Using a spade or a shovel, dig a hole about 12 to 18 inches deep and 18 to 24 inches wide depending on the size of the bare root plant.
Break up the soil and remove any large stones as you dig. Pile it up as backfill on the side. Mix a handful of bone meal or superphosphate into the backfill soil. If the soil is poor, it is also a good idea to mix in 1 to 2 shovels of compost or well-rotted manure and put an equal amount in the bottom of the planting hole. Do not add any other fertilizer at this time as this risks burning the newly forming roots.
Position the Graft Union
Make a mound in the center of the hole. Recommendations vary for the best planting depth of grafted roses. Some growers recommend to plant the graft union above the surface. The other recommendation is to position the plant so the graft union is 1 inch below the surface of the soil. Spread the roots evenly down the sides of the mound. If there are any extra long roots you can prune them back.
Prune Back Long Canes
Newly planted rose canes should not be longer than 6 to 8 inches. Cut the canes after planting if necessary so the plant can direct energy into establishing roots instead of maintaining top growth.
Water and Mulch
Water the newly planted rose deeply and apply 1 to 2 inches of mulcharound the base and over the entire root zone to preserve soil moisture and suppress weed growth. Keep the rose well-watered, every other day if it does not rain, until you see new growth.
How to Pot Your Bareroot Rose
Follow the same procedure when planting roses in pots (such as patio roses and other suitable varieties for container growing). Fill a large planting container at least 12 inches in diameter about two-thirds full with potting soil, Make a mound in the center and follow steps one through six. Fan out the roots and fill in around them with potting soil. Water lightly and allow the water to drain, This helps settle the soil, and remove air pockets.
