THIS YEAR HAS actually been wonderful for me because of the new horticultural experiences I have been afforded.
Not only do I get to create those wonderful floral arrangements at Colette’s you saw last week, but I have another new duty.
A magnificent gardener, Sharon, just retired this year on Jan. 1 and I was fortunate enough to be hired to continue her work at two phenomenal gardens, Colette’s being one.
Now, at Beth and Cappy’s, I get to tend a beautiful sculpture park and garden.
These gardens contain a plethora of roses and since tending roses at the age of 4 is the longest garden job I’ve done: Let’s talk about roses.
Roses are a labor of love because they are laborious.
Tend them all the time and make sure their soil is full of organic material, well weeded and cultivated.
Next and most importantly, realize how the plant reacts to your cuts and know the proper time to prune.
Always prune just above (⅛ to ¼ inch) a node, branch, stem or leaf set.
This is crucial to the plants physiology.
Cutting close to the node releases plant hormones that seal the cut and stimulate growth.
Leaving horns, which are cuts between the node, that leave a stub are far less stimulating and result in decaying plant tissue which, like gangrene, slowly works its way down the appendage and kills the host.
Finally, realize the node you cut above will grow now more rapidly than it otherwise would have done.
This is important in rose pruning.
It will also grow at the angle and direction it is pointed.
This is the art of pruning.
By deciding where you can make the actual cut, you are really deciding where that plant will grow — and grow more rapidly.
A weekly job is removing dead wood, old canes, spindly growth and crossover branches.
And now it is time to shape prune them — definitely no hacking here.
In roses, it is all about the height of the cut and the resurrection of the eye (node).
You want to make sure the cut is just barely above a node, facing outward from the center of the plant.
We are trying to create an open plant that is well-lighted and open to air circulation to encourage good strong healthy flowers and stems.
So here comes the list of rose types and their pruning styles.
Hybrid tea roses
These are the majority of people’s roses and are ideally cut 18- to 22-inches high, leaving 3 to 5 good canes.
Then continue to prune low as you harvest or deadhead at a 24- to 36-inch height.
Floribundas and grandifloras
These rose types are similar in style to hybrid teas. They are ever-blooming roses and tend to be more vigorous.
They are pruned slightly higher, about 24-inches above the ground.
If you want well-formed thick balance plants with fewer but larger bloom clusters, prune now at 12- to 18- inches high.
Through the summer, keep harvested canes re-pruned at a 24- to 36-inch height.
Species, shrub, old world
These are quickly becoming new favorites in the garden. They can be short, tall, bushy or have wonderful spreading ability.
They bloom profusely throughout the year with little care.
Because they flower on short laterals (branches) that are produced each season on older wood, prune very lightly to shape and open up the thicket to light and air.
Make sure to remove the crossover, rubbing branches inundating the center.
Climbers
These vigorously growing plants do much better when filled with lush new wood, so cut them back to 3½ to 4½ inches high.
If you are training it on a covered area, cut the side lateral off the main cane leaving two or three nodes. Yes, that is 80 percent of the plant.
Miniature roses
These are great novelty items and should be thinned and cut back to just 4- to 6- inches high. Remove the debris being collected in their centers.
Tree and patio roses
Absolutely get these neat items and never, ever let the shoots grow below the graft along the canes.
On these plants, pruning to shape is the key.
Now and throughout the season, cut out misdirected branches. Always thin spindly growth and select cut at shape enhancing, outward-facing nodes.
When you are done with your roses, clean away all disease-harboring leaves and prunings.
Do not forget to fertilize the newly stimulated plants and mulch. It is the last key to perfect roses. And never, ever, hack away at your roses.
So, please stay active on your roses and make sure to dis-bud your grandifloras if you want florist-quality, long stem roses.
This is done by simply removing all flower buds except the large center “terminal bud.”
And above all — stay well all.

Disbuddng roses will produce quality, long stem, florist-grade cut flowers. It is accomplished by simply removing all side buds except the main terminal bud, as seen here. (Andrew May/For Peninsula Daily News)
