Selecting a disease-resistant rose is the single most effective way to avoid problems and the need for chemicals. You might start by considering some of the old rose varieties, many of which have natural disease resistance. You can also look to many of the modern roses, which are now being bred for improved disease resistance. Hybrid teas are notoriously disease-prone, and seem to lure every insect pest from miles around. They can be difficult to grow without an arsenal of chemical dusts and sprays.
Remember that light changes as the angle of the sun shifts throughout the season. If you live in the upper half of the U.S., choose a site that will offer full sun year-round. The more sun you have, the more flowers your plants will produce. In the lower half of the U.S., choose spots with a little bit of afternoon shade. This protects blossoms from the scorching sun and helps your flowers last longer.
can someone help me. I am trying to propagate roses and planted the stems around 5 weeks ago. The stems beautifully grew leaves etc on its own but today when I took out one stem, it has only grown a callus so far. So my question is how long does it take for the roots to grow? When I started I moistened the soil a bit at that time and since then never again. Each stem is in a pot surrounded by a ziplock bag tied to it. All stems are growing leaves. Should I start watering them more often? Would that mean I have to take the bag off every time and then tie it again? Hoping to find some answers from more experienced people.
Roses are flowering perennial plants prized for their beautiful flowers, which are made up of delicate and layered petals. One of the best ways to propagate new roses is to take a cutting from an existing plant and grow it into a whole new rose bush. When you grow roses from a cutting, you cut a stem from a healthy plant and root it in a growing medium so it grows into an independent plant of its own. However, you can also propagate roses by dividing an existing plant, but this requires a little more effort than with cuttings. To propagate by division, you have to dig up an entire rose bush, cut the root system in half, and replant the two halves as separate bushes.
Some people don't bother to take the time to do this, but others do. While the rose seeds are soaking, you will see that some sink to the bottom and some float on the top. The seeds that float are sometimes not viable, so you might want to throw them away. The rose seeds that sink are said to be the good ones, and are the ones to plant. There are pros and cons to this theory, and many rose hybridizers simply plant all the rose seeds that are harvested.
A special stainless steel screen on the handle of the unit raises up when it is dry. When this happens, it throws the mercury switch which opens the solenoid valve and starts the misting cycle. When this stainless steel screen accumulates enough mist, the weight of the water drops it down again, shutting off the mercury switch, closing the solenoid valve. It needs practically no care or maintenance and can be left on, unattended day and night. This control unit is a very practical instrument which will have a long lifetime of carefree maintenance. There are no clocks to adjust, and it is not affected by water conditions. It works simply on the weight of water. The major benefit of the Mist-a-Matic is to control the misting cycle according to weather conditions. Too much water promotes disease and wastes water. Too little water causes leaves to wilt and failure to root. The Mist-a-Matic distributes the correct amount of water. In hot weather, the unit will turn on more frequently as the water evaporates. In cooler weather, the unit turns on less frequently. For operation, you will need to plug the unit into an electrical outlet. You need to hook it up to a water source with misting nozzles.
Just as with many other shrubs, roses can be grown from cuttings. It’s not a fast process – it may take a couple of years before your new plant produces flowers. But if you have a favourite rose, it can be fun to try. The cuttings need to be taken fresh from a healthy plant – don’t try to grow a new rose bush from the bunch of cut flowers you have sitting in a vase. And as roses bushes are pruned during winter, this is the most convenient time to take and pot up your rose cuttings.
When you grow roses from seed, you are essentially developing new varieties of roses. If the rose fruit -- called a hip -- was produced by bee pollination, you don't know what varieties were crossed to get the seeds. Rose breeders hybridize chosen varieties and select for particular traits in resultant seedlings. However, each seedling will be a surprise. Rose seeds have to be collected in the fall, cleaned, and cold-treated before they are planted. Even though the cleaned seeds may look dry, they are not dry inside. If rose seeds are allowed to sit around in the open air and dry up completely, they will not grow.
After the rose seeds have soaked overnight, rinse them in a strainer and place them into the blender with at least a cup of plain purified water (making sure all seeds are covered), and turn it on for a few minutes. It usually doesn't chop up the seeds, but rather, it will clean off the pulp remaining from the rose hip, which would otherwise mold if left on the rose seed. You may see a few seeds chopped up, but those usually aren't viable anyway. Flush the rose seeds again through a strainer using fresh purified water.
Black Spot: Rose plant leaves with black spots that eventually turn yellow have black spot. This is often caused by water splashing on leaves, especially in rainy weather. Leaves may require a protective fungicide coating, which would start in the summer before leaf spots started until first frost. Thoroughly clean up debris in the fall, and prune out all diseased canes.
Put the rose cuttings directly into water. It’s very important for the rose cuttings to stay hydrated so that they don’t dry out before you plant them. Immediately after you take the rose cuttings, put them in a cup of room temperature water until you’re ready to transfer them. Ideally, you’ll be ready to put them into the soil right after you cut the stems.
This is a fungus called black spot. Left untreated, it can cause all the leaves on your roses to turn yellow and fall off. It will also affect nearby plants, as it spreads by spores. Remove ALL INFECTED material and throw it away or burn it. Do NOT leave it on the ground as this fungus is very hardy. It can survive winter and travels very easily, even after being removed from the affected plant. Spray your plants regularly (bi-weekly) in the growing season with a good fungicide (I like the Bayer products). You can also add a little bit of dish soap and baking soda to a spray bottle with water and spray the entire plant.
Hi Katherine, You may have hit the reason. One of the most common reasons for roses not blooming well is the use of high nitrogen fertilizers or the over use of them. This will result in few to no blooms or small blooms and lots of foliage. Use a well balanced food or fertilizer when feeding your roses so that all of the rose’s nutritional needs are met.
Buy bare root or potted roses. Once you've picked out the types of roses you want to plant, decide in what form you want to buy them. Bare roots are the roots of roses that are planted directly into the ground. You can also buy young roses that have already been planted in a small pot, and transplant them to the ground or another pot. Either type may be purchased in a nursery. Rare rose varieties may be found online.
You must monitor the seedlings as they grow in their new pots for colour, form, bush size, branching, and disease resistance. Roses with weak, unhealthy or unattractive flowers can be discarded. It will take your new seedlings at least three years before they reach maturity and develop into a big bush. However, the first flower can be seen after one or two years.
Rose propagating methods have changed over the years, from the simple own-root varieties of the Victorian era, and progressing to the budded hybrids of the 20th century with its many options of exotic understock such as Rosa multiflora, Dr. Huey, Manettii, and Fortuniana. Now, rumor has it that many of the modern hybridizers and commercial growers are interested in returning to the simplicity of yore. Today's commercial rose growers are finding that budded roses are just too labor-intensive and expensive to produce. Because of this, it appears that we can look forward to more own-root roses being introduced and sold at our local nurseries in the future. Own-root roses will eliminate suckering and hopefully will eventually help to eradicate mosaic virus.
Wonderful instructable! And THANK YOU! I have the most beautiful smelling rose in my backyard that was there when my father purchased the house (I purchased it from him... the house, not the rose, the rose just came with it :) ) and I've never been able to identify it or find anything that smelled nearly as sweet. It blossoms with two buds a year, consistantly, never producing more or growing any further. Both buds are now dead so I think I will cut them off the moment I get home and start this process. Maybe in a couple of years I'll have a whole patch of these magnificent bushes. Again, many kudos and thanks.
I planted mine in to the ground just like a normal rose bush, amending the soil with rose fertilizer and alfalfa meal. It is gorgeous, but because it's low to the ground, you should make sure to use drip irrigation or a soaker hose to water it so it doesn’t get black spots from the water splashing on the leaves. If yours is in a pot, let it go dormant in the garage or close to your home to keep the pot from freezing. Keep it watered and in the spring it should come back with more fertilizer to keep it happy.

Taking rose cuttings can lead to a new crop of beautiful, successful roses. Like many other plants, it's important to choose a sunny spot for your rose cuttings that has moist soil. Cutting strong, healthy stems right above a set of leaves makes for great growing conditions, and dipping your cutting in a rooting hormone will help the roots take faster. By keeping your rose cuttings well hydrated, you'll have strong roots in no time.
I have a hybrid tea (Sterling Silver) rose plant in a 1 gallon plastic pot that was recently gifted to me in September. I have not had time to plant it yet, and am afraid to do so now b/c we had our first frost this week. Could you please provide me with any tips on how to overwinter it indoors? I do have one room in the house that is cooler (65 to 68 degrees, F) and has east, west and south-facing windows that I think would be ideal for overwintering the rosebush in. Do I need to repot it into a clay pot, and should I hard prune it now, or just remove any deadwood? This particular rose varietal has a lot of sentimental meaning for me, and I really want to keep it alive so that I can plant it outdoors next spring. Thanks in advance for your help!
