Aside from times of extreme weather, roses can be planted at any time during the year. The extreme weather conditions that we advise against planting in are when the ground is frozen, water-logged or during a drought.
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.
Additionally, roses planted in April and May are doomed to face the upcoming summer heat sooner than later. Roses planted in February and March are able to establish roots while the weather is mild and are able to deal with the heat better once it arrives.
Bare root roses should be planted between November and March, while containerized roses can go into the ground at any time of year. If possible, opt to plant roses in bare root form in winter or early spring to give your new roses the best possible start.
You may not think of late summer and fall as a time for rose gardening. Sometimes, however, roses will actually establish better when planted in fall than when planted in late winter through early spring.
Meanwhile, summer planting is also not ideal because of the high heat during this season. In San Diego, for instance, the temperature in August can hit 78°F. That's why the best time to plant roses in Southern California is either in spring or fall.
Personally I think fall is a terrific time to plant roses. The exception may be if you live well up north where bitter winters come on quick and early, but for most of us it's a good time. Here in our zone 7/6 foothills of the Blue Ridge I start planting in late August when the nights turn cooler.
The answer is: yes! Roses are particularly well suited to fall planting. They tend to benefit immensely, and you can pay a quarter of the price for plants that you might be charged during the spring.
*East, South, or West (not the North side of the house as there is not enough sunlight for these beauties!). * More specifically, Roses need AT LEAST 4-6 hours of sunlight a day, minimum! Think of them as sunbathers- they love to soak up the sun. *Also, try to plant Roses where you can also enjoy them from inside.
Roses like morning sun whenever possible. Morning sun burns the dew off the roses and makes them less likely to suffer from mildew and other diseases. However, afternoon sun tends to be stronger than morning sun so, if you are only able to provide the rose with a half day of sun, choose the afternoon over the morning.
By adding coffee grounds to your roses, you create a barrier that will keep pests away and allow your rose bushes to thrive. So if you're wondering whether coffee grounds are good for roses, the answer is a resounding yes! Coffee grounds are an inexpensive and readily available organic fertilizer for your roses.
Give your roses 1 to 2 inches of water each week in a single watering session from early spring through fall. Increase the frequency to every three or four days in hot and dry weather. Porous soils will also benefit from additional deep soakings.
Autumn is an excellent time to prepare rose beds even if planting is delayed until spring. Select a location with good drainage, away from tree roots, and where the sun shines at least four or five hours a day, preferably more.
Fall is the second best time, toward the end of October or in November, if the soil is still reasonably warm. The plant will do better the longer it has to reestablish itself before winter cold arrives. You can transplant roses in mid-season, say June or July, but it's risky.
Growing roses in containers is ideal for small gardens or where space is limited, such as on a patio or terrace. Not all roses will thrive in containers, so it is important to choose the right type, such as a patio or miniature rose.
Watch out for particularly prolonged dry spells. Newly planted roses – water every two or three days. Established roses – water once or twice a week as needed to keep the soil moist around your roses.
Helps With Nutrient Intake
"When rose plants have sufficient magnesium levels, they can more effectively utilize these nutrients, promoting overall growth and development." Additionally, Epsom salts' sulfur content also helps with nutrient uptake.
Growth Rate
Most roses grow fairly rapidly. Tea roses may reach their full height after only three to four years and grow to that height each year despite being cut back each year. Many of the modern roses will only live six to 10 years unless given exceptional care.
While most rose bushes love the sun, the intense afternoon heat can be a major stressor for them, especially when bud and bloom rose bushes (those growing, budded, or blooming in their nursery pots) are planted during the hotter period of the growing season.
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.
