About Roses

Roses are the flower of love. Many of us have fond memories of favorites in our mother’s garden or of a beautiful bouquet given or received on Valentine’s Day. It’s dormant season for roses which is good for both pruning and adding a few to the garden.

As a designer I have clients who have inherited roses and want to keep them as a remembrance. Others want to create a cutting garden filled with roses and other perennials. Don’t feel guilty for growing those beauties in your own garden. They use less resources than you think and there are many ways to grow them sustainably.

Roses, whether bush types, climber or ground cover carpet varieties, use a moderate amount of water in order to thrive according to the latest Water Use Classification of Landscape Species (WUCOLS) list. This amount of summer irrigation is the same as many of the plants on the list of Scotts Valley Water District’s 800 Approved Low Water-Use Plants for lawn replacement. Plants such as Emerald Carpet manzanita, Joyce Coulter ceanothus, Siskiyou Blue fescue grass, Pacific wax myrtle, butterfly bush, yarrow hybrids and Tapien verbena have similar water requirements.

Since now is the time to prune your roses here are a few tips.

Strike it Rich hybrid tea rose

Prune shrubs moderately to keep them compact. The goal is to keep the center of the plant open for good air circulation aiming for a vase-shaped bush with an open center. Cut out canes that cross, appear weak or are diseased, spindly or dead. Healthy canes appear green or reddish while old and dying canes are brown. Cut back the remaining stems by about one third. When pruning, cut canes at a 45-degree angle just above an outward facing leaf bud or a swelling on the cane. Clean pruners after every use to prevent the spread of disease and keep your pruners sharp.

Prune heirlooms roses such as David Austin and other old antique garden roses less because their open look is part of their charm.

Same goes for climbing roses. Cut out extra stems if there are too many and also cut back long established canes to about the place where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will make the cane flower along its complete length for a beautiful spring display.

Pluck off and rake away any old leaves. They can spread fungal spores. Consider spraying dormant plants with a combination of organic horticultural oil and copper soap or lime-sulfur. If you usually only have problems with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light horticultural oil in 1 quart water and spray every 7 to 10 days during the spring.

Prune your roses throughout the growing season, too. Deadheading, or cutting off spent flowers, encourages plants to re-bloom. Mulch around your roses to conserve water and encourage soil microorganisms.

Don’t worry whether you’re pruning job is perfect. Roses are super forgiving and you can always trim them up again later.

Pruning Roses- How, When & Why

In between storms I’m itching to get outside and do something in the garden. It’s too early to cut back the perennials as some frosty nights are sure to come our way between now and mid-March. But it’s just the right time to start pruning the roses. It’s best to prune your roses before they start leafing out or some of their energy will be wasted.

Last year, mine were looking just fine in January, thank you very much, so I thought I’d skip the pruning and removing last year’s leaves. Boy, what a mistake. Oh they looked great in January and February when there was no precipitation. Then some rain fell in March. I’m not kidding when I tell you that every single leaf got black spot and rust. My rose varieties are usually resistant to disease but they could not fight back against the fungal spores lurking in the soil just waiting to colonize those old leaves.

Roses give so much back I think they are worth the extra mulch and a little extra water to keep them producing those lovely blooms. There’s nothing quite as dramatic as a mixed bouquet of scented roses on the table.

I want my rose bushes to produce lots of roses on a compact shrub and not just a few exhibition size blooms so I prune my shrubs moderately. My goal is to keep the center of the plant open for good air circulation aiming for a vase-shaped bush with an open center. I’ll cut out canes that cross, saving the better of the two, prune spindly and diseased stems and dead wood. I’ll also prune canes that appear weak or broken. Healthy canes appear green or reddish while old and dying canes are brown. Then I’ll cut back the remaining stems by about third. When pruning cut canes at a 45-degree angle just above an outward facing leaf bud or a swelling on the cane. Slant the cut away from the bud to encourage growth outward. Clean pruners afterward to prevent the spread of disease and keep your pruners sharp to make clean cuts.

Same goes for climbing roses. Cut out extra stems if there are too many and also cut back long established canes to the place where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will cause the cane to flower along its complete length for a beautiful spring display.

Heirlooms roses such as David Austin, other old antique garden roses, and floribunda roses require less pruning because their open look is part of their charm. Keep this in mind and prune lightly. Old garden roses that bloom once in the spring should be pruned after flowering.

I got off easy this year as one of my roses was pruned and de-leafed by a deer who got inside the fence one night but the others are getting pruned the right way and at the right time. I know those old leaves will spread fungus spores and possibly infect the new growth so I’ll patiently pluck them off.  If you have a huge climber this might not be possible and spraying with fungicide may be your only option if you’ve had disease problems in the past. Rake up the debris beneath the plant and discard to eliminate overwintering fungus spores. It’s a good idea to spray the bare plant, coating the trunk, branches and twigs and the surrounding soil with a combination organic horticultural oil to smother overwintering insect eggs and a dormant spray like lime-sulfur or copper soap to kill fungus spores. If you usually only have problems with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light horticultural oil in 1 quart water and spray every 7 to 10 days during the spring.

Pruning intimidates some gardeners but when you understand the reasons for making the cuts pruning becomes less daunting. The reasons to prune are for health, appearance and to control size.

Prune your roses throughout the growing season, too. Deadheading or cutting off spent flowers encourages plants to re-bloom. Every time you cut a rose bloom to bring it indoors or deadhead a fading rose prune the stem down to shape the plant at the same time. Prune to a spot that has at least 5 leaflets. Roses grow from the point where they are cut so consider the overall shape of the plant as you snip.

Don’t worry whether you’re pruning job is perfect. Roses are super forgiving and you can always trim them up again later. Roses are like redwoods -you can’t kill one- they’re the energizer bunnies of the plant world.

Pruning Roses for Bloom & Vigor

rose_pink_cabbageIn the spirit of practicing what I preach I set out to do a little pruning around the ‘ol homestead last week. Since I cut back the hydrangeas pretty hard last year this time round I did only a bit of shaping. The fuchsias haven’t gone totally dormant this year but as they bloom on new wood I cut them back by a third. Then I looked at the roses. I have a few climbers and several shrub roses. This is how I’m going to get the best rose show ever this year.

Rose Tips and Tricks

The_Mystery_RoseSurrounded by roses of nearly every color in the rainbow I smelled vanilla, spice and honey. The sun peaked in and out of the clouds allowing the vivid hues of the petals to change with the light. I was enjoying the garden of rose aficionados Mark and Lane Maloney of Scotts Valley. Among their 40 rose bushes I was to learn how an expert cares for these beauties.

The oldest roses in the garden are 60 years of age. Mark dug them from his mother’s collection when she died in Atherton 5 years ago. He starting collecting most of his other roses 20-30 years ago when he and Lane moved to the Scotts Valley property. Because he seldom has a rose die the only new rose in the garden is a double blooming red variety called Legend and named after Oprah. It was just starting to open on the day I visited this amazing rose garden.

I asked Mark which rose is his favorite. It was hard to pin him down to just one. The Distant_Drum_rosegarden is divided into two separate beds. One bed is devoted entirely to roses while another blends roses with other perennials. I admired a large shrub covered with pinkish flowers and he replied “this is one my most beautiful roses. It starts out a deep dusty rose then fades to lighter shades as it ages”.  Most of the roses in the garden have large ornamental name tags that he purchased online. The sign at the base read Distant Drums.

I was drawn to the Double Delight as I know it’s one of the most fragrant. Another rose with an incredible scent is Dolly Parton but on this day it hadn’t opened yet. Mark described it as “big and pink”, which seems appropriate.

Strike_It_Rich_roseDouble Delight, like many roses, blooms in cycles. They set buds and bloom for a month, rest for a month, then set another round of blooms. Mark said he usually gets about 3 cycles per season. One of his favorite roses will bloom all summer non-stop. Strike it Rich lives up to the name with lovely sherbet-orange flowers.

Mark also likes Black Magic with deep, reddish-black blooms that last 2 weeks in the garden as does another of his favorites, Fame, with pink flowers so bright they are nearly iridescent .  With deep yellow blooms Gold Medal caught my attention. But then I saw St. Patrick with those cool greenish-white blooms. Mark told me that in the white rose department he thinks White Lightnin’ is a beautiful rose as is the classic, JFK.

The roses in the Maloney’s garden are lush and healthy. What’s your secret I asked? Mark Perfect_Moment_rosesmiled and handed me a Rose Garden Calendar he had prepared on his computer for me. In a nutshell this is how he does it.
Late December- prune heavily down to about 24″ tall.

Early January- spray roses with dormant spray and again in early February.

March 1- fertilize and repeat each month through September.

Mark uses a systemic fertilizer which keeps insects at bay. He also uses an acid fertilizer once or twice a year as well as putting banana peels on the surface of the soil for potassium. I laughed when he told me his banana peel tip. I was nearly standing on a blackened peel with sticker still intact when he shared this info.

His other “secrets” include picking off diseased leaves regularly, pruning lightly throughout the year, mulching with several inches of chipped wood and watering with 1″ of water per rose each week applied in a trough  surrounding the shrub.

Mark is a member of ARS (American Rose Society) with he suggests as a good source of information and also rose recommendations for different areas and climates. He also maintains the roses at the Scott House at Civic Center. So when Mark talks roses, I listen.

Roses of Yesterday

rose_Kathleen_closeup 3Under blue skies on a perfect spring day I sat recently with Colly, my friend, fellow columnist and gardening enthusiast, surrounded by roses, roses and more roses. Next to an old apple tree and a gnarled cherimoya we enjoyed a delicious picnic lunch Colly brought while she shared stories about this rose nursery called Roses of Yesterday.

Back in the 1960's one of Colly's many jobs was to proof read the catalog for Roses of Yesterday and Today as it was then called so she is quite familiar with the history of this rose business located on Brown's Valley Rd. in Corralitos. It's not quite a grand as it was in the old days but the massive old roses growing in the ground were magnificent in size and we admired and rated each one on the fragrance scale.

Roses of Yesterday, one of the oldest antique rose nurseries in the U.S., was established in the 1930's. It has passed through several generations and owners since then. They still use the honor system to sell their old, selected modern, unusual and rare rose varieties. A young father, kids playing in the car, loaded up a collection of potted roses and deposited a check in the cash box before leaving.

Another sign advised that the nursery doesn't spray their roses with fungicides, insecticides, rose_Kathleen_bench 3herbicides or other chemicals and the rose petals can be used for salad, jams, spritzers and teas. I did notice some rose slug damage on some of the roses but it was minimal. We noted the Sally Holmes roses and the rugosa roses had the least pest problems.

The garden contains many huge old roses. The first mammoth plant we encountered, Newport Fairy, was over 15 feet tall and nearly as wide. Covered with hundreds of small pink flowers it provided cover for many small songbirds who hopped inside searching for insects. This hybrid multiflora rose was first bred in1908. Lots of Red Admiral butterflies and Swallowtails found the surroundings to their liking, too.

We walked under a Cecile Brunner– engulfed pergola and then we saw it. Against a fence in filtered light, a spectacular single white rose with stiff, butter yellow stamens shaded an old wooden bench. We searched for the name tag and found, buried among a groundcover of sweet violets, the name Kathleen. This unusual and unforgettable hybrid musk rose from 1922 blooms repeatedly with blossoms richly perfumed. The catalog states the flowers drop cleanly and orange rose hips form along with the new blooms.

Several English lavender plants grew between the rugosa roses. We especially liked a small double magenta one called Rugosa Magnifica as well as a lovely white variety named Rugosa Blanca. Rugosa roses are very old dating back to before 1799 and bloom repeatedly with a marvelous fragrance. Large orange rose hips will form when the disease and pest resistant foliage drops. These edible hips are very high in vitamin C and are also relished by wildlife.  I've been told the crinkly foliage of rugosa roses is deer resistant.

Growing nearby, a burnt orange rose got our attention. This amazing rose with two tone reddish orange petals and a lighter orange to yellow reverse is similar to Hot Coca. Called Stretch Johnson the flowers have the classic fragrance of rose petals and the disease resistant dark green glossy foliage of this floribunda was lovely.

The garden contains roses of all types especially old fashioned single roses as well as ruffly cabbage varieties. One bright pink single rose was especially beautiful. We thought the name tag read Rosa Wichuraiana but it must have been referring to the white groundcover rose nearby. We also loved a bright pink rose called Marguerite Hillig with its sweet fragrance and graceful arching canes.

The 4 inch dusky pink blossoms of Dainty Bess, a hybrid tea climbing rose, decorated one of the fences. rose_Sally_Homes2 3I learned this is a classic variety among hybrid teas since 1925 from the online catalog. The non-stop blooms are exceptionally long lasting on the plant and in bouquets.

From Ballerina to Climbing New Dawn to a huge Heinrich Munch with double pink blossoms covering a rose bush 20 feet across with a foot wide trunk, I enjoyed every inch of this old rose garden and nursery and it was fun to hear personal anecdotes from Colly about Dorothy Stemler,  the rose aficionado who's touch can be still be seen in the gardens of Yesterday and Today.
 

Thanksgiving Plants & Food

Have you noticed how many plants are named after food? At this time of year when we are thankful for friends and family and this wonderful place we call home, I can't help but think about food, too. It's the most important thing we share year round. We eat to celebrate, we eat to comfort ourselves. Surround yourself with plants that remind you to give thanks whenever you look at them.

What makes you think of Thanksgiving dinner more than pumpkin pie? Many versions have been created to appeal to just about any palate. If you grow Pumpkin Pie African daisy you can bring these recipes to mind whenever you admire the blooms in your garden. Flowering over a long season starting in the spring their showy, vivid orange flowers attract birds and butterflies.

Maybe you're a gourmet cook and desserts after Thanksgiving dinner are extraordinary at your house.  If you're not a fan of pumpkin perhaps a creme brulee  would be more to your liking. This classic dessert first appeared in cookbooks in 1691. Creme Brulee heuchera with its peachy-bronze leaves, Creme Brulee coreopsis with custard yellow blooms or a fragrant Creme Brulee shrub rose growing in your garden would remind you year round of this delicious dessert.

Someone often brings deviled eggs as an appetizer before Thanksgiving dinner usually sprinkled with a dusting of paprika. If you have several Paprika achillea in your low water-use, deer resistant garden you can think of these goodies every time you see them.

Who doesn't like chocolate any time of year? Dark chocolate, milk chocolate, hot chocolate, white chocolate, they're all good. Plant Chocolate Chip ajuga groundcover  with its beautiful lacy blue flower spikes in spring in sun or partial shade. It really stands out. And who could resist a rose called Hot Cocoa? This award-winning floribunda rose with ruffled, very fragrant chocolate-cherry colored blooms was first introduced in 2003 and has remained popular ever since.
 
If you don't have a chocolate cosmos to enjoy on a summer day in the garden you're missing a rare experience. Very deep burgundy flowers really do have the scent of chocolate. They make a good cut flower, look great with green and white in a bouquet and the fragrance is good enough to eat.

There are many plants that remind us of Thanksgiving with family or a get together any time of year and they all sound so delicious. Raspberry Sundae or Bowl of Cream peonies sound yummy as do Mango coneflower, Strawberry Candy daylily, Plum Pudding coral bell, Cranberry Ice dianthus, Lemon Swirl lantana, Watermelon Red crape myrtle, Tangerine Beauty bignonia or Wild Cherry azalea. How about Bowl of Cherries campanula, Carolina Allspice, Strawberry Lemonade mandevilla or Raspberry Tart coneflower?  I could go on and on.

My blooming Thanksgiving cactus says it all. Almost overnight it has burst into bloom reminding me of all the many things I am thankful for. Take the time to tell those around you how much you appreciate them and count your blessings every day.
