Sacramento Digs Gardening: Tell your roses to take a break

What to do when your roses won't stop blooming and it's time to prune

It’s time to tell your roses: Knock it off!

November’s mostly dry and relatively warm weather coaxed bushes to just keep flowering.

Some roses just won't quit, such as this Diana, Princess of Wales hybrid tea,
still blooming in mid December.

Although I appreciate the bonus December blooms, that makes it hard to winter prune.

Roses need pruning to revitalize the bush and reset their biological clock. Otherwise, canes sprout atop canes, creating tangled messes 10 feet tall (or more) with blooms way out of reach.

You can’t smell the roses if they’re way over your head.

How do you get a rose bush to slow down and take a winter break? Allow rose hips – the rose fruit – to ripen. Instead of clipping off spent blooms, let the hips that swell at the base of each flower turn deep red-orange. That cues the plant that its work is done for this year.

After the hips mature, the bush will drop its leaves and stop pushing out fresh growth. That makes winter pruning much easier; stripping the bush of all foliage is part of the process.

When is the best time to prune?

“I usually recommend it’s a great time to prune in the Sacramento region from approximately Dec. 15 to Jan. 31 or, if really necessary, up to the first week in February,” said T.J. David, founder and curator of the World Peace Rose Garden at the state Capitol.

Several local pruning clinics and events are planned for early January, including the McKinley Park prune-athon on Jan. 4. (More on those events later.)

My annual goal is to get my roses pruned by Super Bowl Sunday; that will be Feb. 2.

Meanwhile, I’ll pick a few last bouquets – and think about making rose hip jelly.

Garden Checklist for week of May 19

Temperatures will be a bit higher than normal in the afternoons this week. Take care of chores early in the day – then enjoy the afternoon. It’s time to smell the roses.

* Plant, plant, plant! It’s prime planting season in the Sacramento area. If you haven’t already, it’s time to set out those tomato transplants along with peppers and eggplants. Pinch off any flowers on new transplants to make them concentrate on establishing roots instead of setting premature fruit.

* Direct-seed melons, cucumbers, summer squash, corn, radishes, pumpkins and annual herbs such as basil.

* Harvest cabbage, lettuce, peas and green onions.

* In the flower garden, direct-seed sunflowers, cosmos, salvia, zinnias, marigolds, celosia and asters.

* Plant dahlia tubers. Other perennials to set out include verbena, coreopsis, coneflower and astilbe.

* Transplant petunias, marigolds and perennial flowers such as astilbe, columbine, coneflowers, coreopsis, dahlias, rudbeckia and verbena.

* Keep an eye out for slugs, snails, earwigs and aphids that want to dine on tender new growth.

* Feed summer bloomers with a balanced fertilizer.

* For continued bloom, cut off spent flowers on roses as well as other flowering plants.

* Don’t forget to water. Seedlings need moisture. Deep watering will help build strong roots and healthy plants.

* Add mulch to the garden to help keep that precious water from evaporating. Mulch also cuts down on weeds. But don’t let it mound around the stems or trunks of trees or shrubs. Leave about a 6-inch to 1-foot circle to avoid crown rot or other problems.
