Master rosarian shares simple rose pruning tips

Why prune? Why now?
Those are prickly questions for anyone who grows roses.
January is rose pruning season in Sacramento. Why? It’s a time when roses usually are dormant, quietly sleeping through a cold winter. Any blooms have turned to orange hips. Foliage has dropped, revealing bare canes.
But not this year. A relatively warm winter and abundant rain prompted lush new growth on many large bushes. In my own garden, I have dozens of blooms on such hybrid teas as Pink Promise and First Prize.
Other bushes that lost their leaves are now showing signs of bud break, a swelling of nodes where new foliage emerges. Early bud break isn’t a problem – if the bush is already pruned. But if that bush is still a thatch of twisting canes, new growth just compounds problems.
Prune anyway, says master rosarian Charlotte Owendyk. If not now, later.
“What happens if you don’t prune? Life goes on; the roses will get bigger,” Owendyk said. “You can trim as needed during the growing season; just don’t do it in the heat of summer.”
Owendyk is one of the featured speakers at the Sierra Foothills Rose Society’s Winter Workshop. Set for 9 a.m. to 1 p.m. Jan. 15 at the Orangevale Grange Auditorium, the free in-person event covers a wide range of rose care topics from pest prevention to finding the right rose for the right place. The Grange is located at 5807 Walnut Ave., Orangevale; face masks are required.
Of course, pruning will be a big part of the discussion. Thursday, Owendyk offered a preview to the Sacramento Rose Society.
“Why prune? The plant needs it!” Owendyk said. “Pruning increases the plant’s vigor – you get more and bigger blooms. Pruning also helps achieve the desired shape and size for that bush. Prune for safety, too; you don’t want canes sticking out into walkways.”

“Generally, you don’t want to remove more than one third to one half of the bush’s height,” she explained. “But if a bush is already the right height or just small, it may only need a little touch up or trim.”
“When pruning, remember the three D’s: Dead, diseased, damaged. Take out any canes that fit in that category,” she added. “Just prune it; the plant will be happy.”
Pruning also allows time for re-evaluation and rejuvenation.
“Look at the structure,” Owendyk said. “Pruning is an opportunity to slowly, over a number of years, rejuvenate the plant. Remove old gray canes – one a year, not all at once – so new healthy canes can grow.”
When pruning, Owendyk always strives to open up the center of the plant, removing canes crossing in the middle. That allows for better air flow and cuts down on fungal disease. It also prompts more healthy new growth.
Strip off any leaves clinging to the remaining canes; it can contain fungal spores ready to infect new growth. Once done, clean up any debris.
“I always top-dress the soil, too,” Owendyk said. “It smothers any fungus on the ground.”

Dig In: Garden Checklist
For week of Sept. 24:
This week our weather will be just right for fall gardening. What are you waiting for?
* Now is the time to plant for fall. The warm soil will get these veggies off to a fast start.
* Keep harvesting tomatoes, peppers, squash, melons and eggplant. Tomatoes may ripen faster off the vine and sitting on the kitchen counter.
* Compost annuals and vegetable crops that have finished producing.
* Cultivate and add compost to the soil to replenish its nutrients for fall and winter vegetables and flowers.
* Fertilize deciduous fruit trees.
* Plant onions, lettuce, peas, radishes, turnips, beets, carrots, bok choy, spinach and potatoes directly into the vegetable beds.
* Transplant cabbage, broccoli, kale, Brussels sprouts and cauliflower as well as lettuce seedlings.
* Sow seeds of California poppies, clarkia and African daisies.
* Transplant cool-weather annuals such as pansies, violas, fairy primroses, calendulas, stocks and snapdragons.
* Divide and replant bulbs, rhizomes and perennials. That includes bearded iris; if they haven’t bloomed in three years, it’s time to dig them up and divide their rhizomes.
* Dig up and divide daylilies as they complete their bloom cycle.
* Divide and transplant peonies that have become overcrowded. Replant with “eyes” about an inch below the soil surface.
* Late September is ideal for sowing a new lawn or re-seeding bare spots.
