Dig a hole that is slightly wider but equally in depth to the rose's root ball. This will generally be about 15 to 18 inches deep by 18 to 24 inches wide. Mix a handful of bone meal or superphosphate into the soil you removed and save it for refilling the hole once the rose is planted.
Dig a planting hole that is two inches shallower than the height of the root ball, and twice as wide. Place the plant in the planting hole. The top of the root ball should be about an inch above the edge of the hole. (Soil will settle over time, so you don't want to plant the rose too deep.)
However, cuttings should be planted right after they're taken, so prepare your spot in advance. You can stick softwood cuttings straight into a prepared corner of your outdoor garden space or plant them in containers or deep trays instead.
Rose cuttings take about two weeks to root if they are softwood cuttings. If you are rooting hardwood cuttings, it can take as long as two months before the roots start to develop. Only plant in the garden if the cuttings will have the time to develop a good root system before they go dormant.
Contrary to popular belief, February and March are excellent times to start planting roses. Many landscapers will wait until April and May to begin planting roses because this is when the plants are already in bloom, and many nurseries will get their stock of roses in around January and February.
Roses are excellent plants for growing in pots. English Roses, with their shrubby, bushy habit are ideal for growing in large pots and containers. Unlike many other potted plants, English Roses will flower in fragrant flushes throughout the summer and into the fall.
Roses are very adaptable and can be grown in almost any soil type given it is well drained, deep and full of humus (decayed organic matter). However, the best soils are those of a medium to heavy loam to a minimum of 35cm, over a good clay sub-soil.
Roses do like coffee grounds, but too much too close can give them a nasty nitrogen burn and can kill your roses. Never sprinkle coffee grounds right next to the plant. There's a great way to…
Roses thrive on direct sunlight. For best results, a minimum of four hours of direct sunlight is recommended. However, even when planted against a north wall (meaning no direct sunlight) roses can still perform well.
Epsom Salt for Roses
Rose growers in particular are strong advocates for using Epsom salts. They claim it not only makes the foliage greener and lusher, but it also produces more canes and more roses.
FOR ESTABLISHED ROSES:
Use a high-nitrogen fertilizer or top dress with alfalfa meal (5-1-2) for the first application to jump-start leaf development, along with epsom salts to encourage new cane development and lusher growth. Add a slow-release fertilizer when shoots are 4 to 5 inches long.
If your roses are looking a little worse for wear, there is one cure that gardeners swear by: Epsom salts. The compound contains elements that are known to reduce the risk of disease, enhance nutrient uptake, and improve flower quality.
They should also be planted in well-drained soil that is rich in organic matter. In especially hot climates, roses do best when they are protected from the hot afternoon sun. In cold climates, planting a rose bush next to a south- or west-facing fence or wall can help minimize winter freeze damage.
Roses thrive on direct sunlight. For best results, a minimum of four hours of direct sunlight is recommended. However, even when planted against a north wall (meaning no direct sunlight) roses can still perform well.
Container cultivation
Position the container before filling with compost as it may be too heavy to move once planted up. Roses love sunshine and should receive sun for at least half the day. However it is important that container-grown plants do not dry out or they will become prone to powdery mildew.
Roses should be planted after all danger of frost has passed. The soil should be warmed up and easy to work after that date. Soil that's too frozen or sopping wet and muddy from spring rains shouldn't be worked. If the soil is muddy, wait until the soil has dried enough to allow proper planting.
WHEN TO PRUNE ROSES. The best time to prune roses is in late winter or early spring, around the time new growth begins. This could be as early as January or as late as May, depending on your climate.
A: In Southern California, it's never too late to plant rosebushes. The popular “Iceberg” roses are super hardy and will rebloom without constant deadheading. They are also available in pink and burgundy flowered varieties. If you want to plant any perennials, it's a good idea to do it sooner rather than later.
Starting rose cuttings in soil is a more reliable method, as it causes less shock for the plant when you transplant it. This method also encourages the development of hardier, sturdier roots. But starting in water is incredibly simple.
You can grow a rose bush from the stem of a cut rose by planting it in a potato. The naturally moist potato keeps the cutting moist while it sprouts roots.
Before planting bare-root roses, soak roots in a bucket of water for at least two hours (no longer than 12 hours). Prune roots that are broken, injured, or too long. 2. Dig a hole 12-18 inches deep and 2 feet wide, keeping the backfill close.
