How To Grow Roses
I believe it is beneficial to first learn the names of the many components of a rose plant. Let's have a look at the materials we'll be using.
You have your roots at the bottom, of course. There's usually a little hump or knot-like place on top of them, but below the canes. The graft union is where the rootstock and scion were connected.
The scion is the component that possesses the attributes you want (i.e. the exact species or cultivar you bought), while the rootstock is chosen for its hardiness, adaptability, and ease of establishment, among other things.
Many rose plants are grafted, which indicates that the roots of one type or species were utilized for the tops of another. The cane is the stalk that supports the leaves, and it often has thorns, which are termed "prickles" on a rose.
Roses have three, five, or seven leaflets in each group.
The bloom is supported by the peduncle, a branch.
The blossom's foundation is the hip. After the flower fades, it becomes a different hue. The plant's fruit is what you're seeing at right now. The sepal, a green outer covering that wraps the flower bud and is visible before the bloom opens, is seen above that. Depending on the variety of rose, each flower may contain anywhere from five to forty or more petals.
The yellow shrub type 'Molineaux,' for example, has 120 petals per blossom. The new growth of the plant that emerges from the buds at the base is officially known as a basal break.
Plants that bloom continuously throughout the year are known as everblooming. They may also be once-blooming, producing just one set of blooms every season. A third variety is repeat flowering, which means you'll see one flush of flowers early in the season, followed by one or two additional flushes as the season unfolds.
Roses can come in single, semi-double, and double flowered varieties. Each bloom of a double flowered rose is made up of many rows of petals. These are the bigger, more traditional roses that most people envision. The flowers of solitary and semi-single roses are more gauzy and simple.
A single row of petals surrounds the center of single kinds, with each petal having five to eight petals. Semi-double flowers feature more petals than double flowers, but not as many.
Roses develop in a variety of ways
A standard rose, sometimes known as a tree rose, is a cultivar with a single trunk and a bushy head that resembles a tiny tree.
Shrub roses, on the other hand, grow in a wide, thick manner. Ground covers, ramblers, and climbers may also be found.
If you're a slacker when it comes to roses (guilty!) or are just getting started, look for self-cleaning roses, which don't need to be deadheaded to keep blooming. Although roses are hardwood plants, their canes are soft and green when they are young. When it comes to propagation and pruning, this differentiation is vital.
Seed to table
Growing them from seed is doable, but it is neither simple nor quick. It is, nevertheless, really satisfying! Purchase seeds or grow your own to get started.
If you intend on saving your own seeds, keep in mind that certain hybrid types are infertile or do not grow true to type.
Furthermore, since bees and butterflies normally manage pollination, you never know which variety of rose fertilized a certain blossom if it occurs organically. However, seeing what you receive might be a delightful surprise.
In a professional breeding setting, a breeder manually pollinates the rose to guarantee that it does not hybridize in an undesirable manner. After four months, snip rose hips from the plant.
If you can't get to work right away, store the hips in the fridge for a few weeks. Otherwise, after collecting the hips, remove the seeds as soon as possible.
Cut each hip in half and use a teaspoon to scrape out the seeds. Soak the seeds for a minute or two in a solution of one part bleach to 20 parts water, then rinse them in a fine mesh strainer under running water.
Set the seeds aside to soak in a dish of clean water. Toss any seeds that float after approximately five minutes; they may not be viable. Soak the seeds for another 24 hours, then drain and massage any leftover pulp out with a cotton towel.
Allow it dry thoroughly on a towel in a cool, dry location before storing in a jar or envelope. Until you're ready to plant them, keep them in a cold, dark location. The seeds must be cold stratified before they may germinate. To do so, dampen a paper towel and fold it over the seeds.
Refrigerate at 38 degrees F in a ziptop plastic bag. Check the paper towel for moisture on a regular basis, and then let it to sit for four to six weeks. The seeds should start sprouting about this time. Plant them 1/4 inch deep in the garden and keep them wet until they reach a height of three inches. Be patient, as it might take anywhere from one to four months to complete.
You may cross-pollinate several varieties of roses to mix the qualities of two plants if you want to get into advanced rose seeding. We won't go into detail about it now, but it's something to consider as you get experience with reproducing these amazing plants.
Cuttings of roses are easy to propagate. The greatest time to go is in the autumn, but you may go at any time.
In our entire guide, we go through the benefits of cuts in the fall and go into more depth.
To begin, cut an eight-inch section off a newly flowered stem at a 45-degree angle. If you don't have time to plant it right away, place the cutting in a glass of water and let it there for a few hours.
Cuttings may be planted in the ground or in containers. Use a four-inch or bigger container with fresh potting soil. Standard plastic containers may be used, however I prefer biodegradable pots like these CowPots from Amazon.
Remove the bottom half of any leaves once you're ready to plant — be careful of thorns! Rooting hormone powder or gel is applied to the cutting.
Using a pencil, make a hole in the dirt and insert the cutting so that half of it is submerged.
If you plant them straight in the ground, you'll need approximately eight inches between them as they develop. Each four-inch container should only have one cutting. While waiting for the cuttings to sprout, keep the soil wet. They must not be allowed to dry out. You may use a cloche to help with this, but be careful not to overheat the cuttings in the sun.
If you're keeping the cuttings indoors, make sure they get at least six hours of direct sunshine each day. When the cuttings have formed a healthy root structure, you'll know it's ready to transplant. If the cutting resists a mild pull, the roots have grown enough. Plant as soon as the soil can be worked in the spring, or six weeks before the first average frost date in the autumn. Harden off the plants for a week before planting them.
Place the cuttings in indirect sunlight for an hour, then gradually increase the amount of time spent outside by an hour each day until the plants can tolerate eight hours of exposure.
By stacking hardwood cuttings, roses may be reproduced. Look for a young cane on the plant's exterior that can easily be bent in the spring, summer, or autumn.
Bend the cane gently to the ground, then cut a three-inch-long slice halfway through it where it meets the dirt. A four-inch-deep trench should be dug. To keep the stem in place, lay a rock on the free tip of the stem and another closer to where it is linked to the plant.
The remainder of the stem should be buried in the ground. Water well, then apply a layer of well-rotted manure to the area. Remove the pebbles after approximately eight weeks and pull on the cane to see whether it has grown roots.
Snip the cane away from the main plant if it continues to resist. Dig six inches below the rooted region and 12 inches surrounding it. Plant the plant as if it were a transplant, keeping it as deep in the ground as it was before.
Purchasing a ready-to-transplant rose plant is one of the simplest methods to include roses in your garden.
They're commonly sold as live plants in one- or five-gallon pots, or as dormant plants in soil with short, leafless canes. You may also buy ready-to-plant bare roots, which we'll go through briefly below and in a separate tutorial.
Plants that are dormant should be planted within a month after purchase, while those that have leafed out may be kept in their container for up to a year if watered regularly.
While many plant nurseries sell roses all year, most growth zones recommend planting them in the autumn or spring. Look for plants with at least three lush, green canes, or purchase from trustworthy internet dealers that provide a warranty.
Dig a hole four times the size of the pot it arrived in. Add one part well-rotted compost to every three parts dirt to the soil you dug out. Backfill halfway with your prepared soil, then soak the roots in water. Soak again after filling the dirt the remainder of the way.
Wild roses should be planted in a hole that is around the same size as the container they arrived in. A decent rule of thumb is to match the water volume to the size of the container, so for a three-gallon pot, aim for three gallons of water. Make certain that the knot is buried (aka the graft union). The little bulge at the stem's base is what you're looking for. The knot should be just barely covered by the dirt when you transplant the plant, regardless of how deep it was in its nursery pot.
First and foremost, do a soil analysis. This is necessary for determining whether or not you need to add fertilizers or adjust the pH of the soil. Most gardens do not have the appropriate soil for growing roses, even if you do.
Loamy, well-draining soil with a pH of 6.0 to 6.5 is required for roses. These plants have shallow roots that may extend as far as the plant's height. To loosen the soil, dig a hole 18 inches deep and 24 inches wide, removing any rocks, weeds, or debris in the process. If necessary, make changes. If your soil is thick clay, you may add sand, or if it lacks organic matter, you can modify it with compost.
These guidelines do not apply to wild roses. Unless your soil is really sandy or heavy clay, you won't have to do anything to change it.
Avoid planting near your home's eaves, where snow or ice might fall off and injure them over the winter. Plants should be placed at least 24 inches away from solid walls or foundations while they're being planted, so they may get enough of air.
Wind-protected roses are also necessary. A powerful blast of wind may easily snap a cane while the plant is in full flower. Plant them next to a fence or other tall plants, but keep at least 24 inches between them and the fence or other tall plants.
Plant away from the foot of slopes, where frost pockets may occur, and low-lying regions where water can pool. Ivy, honeysuckle, and morning glory are all aggressive vines to avoid with roses.
Almost all rose varieties need at least six hours of direct sunshine every day. There are, however, certain varieties that thrive in partial shade, so do your homework to find out what your plant requires.
If you must provide shade to your roses, do it in the afternoon rather than the morning.
Watering need a little additional attention to prevent future issues. Watering at the base of plants early in the morning ensures that everything dries out before dark. On the other hand, if you need to manage insect concerns, treat your plants as required on a sunny day. Water your roses once a week with two inches of water. You'll need to offer more irrigation if you don't receive enough rain.
What's the best way to know? A rain gauge, which may be purchased or built, is an essential instrument for cultivating a wide variety of plants in the garden. Newly planted roses should not be fed. Allow them to settle in and do their job for a while.
It's time to bring out the food when real leaves appear on fresh growth.
To supplement plants during the first six months, use a fertilizer that promotes root development, such as Neptune's Harvest Organic Seaweed Plant Food, which is available on Amazon.
After that, you may use a conventional fertilizer.
Many products created specifically for roses are available, such as Great Big Roses Natural Compost Extract, an organic plant food available on Amazon. If you choose anything different, be sure to stay away from anything with a high nitrogen content. If you don't, you'll end up with a lot of leaves but few blooms.

Maintenance and pruning
Roses don't live indefinitely. The elder canes eventually die off, and new canes sprout up in their place. Those ancient canes must be taken away. You should also trim plants to keep them healthy and in form, as well as to protect them from the elements during winter.
Pruning may also assist manage pests and disease, as well as foster new blooms.
You may prune in the spring or the autumn, just before the plants become dormant. When the blooms have stopped blooming, deadheading should be done on a regular basis throughout the season.
Maintain proper separation by pruning them back to a few inches from buildings or other structures.
Keep these three attributes in mind as your plants develop during the spring and summer: brown, bent, and scorched. The first two go without saying. Plants that have been burned may seem orange or rusty, or they may be completely dry.
Trim any canes or buds that have any of these characteristics down to the first node on the stalk with five leaves attached. The node is where the five-leaf leaflet attaches to the stem.
