‘Double Knock OutÂ®’ Rose, inducted into the World Federation of Rose Societies Hall of Fame is my husband’s favorite rose. He requested, when we moved back to Illinois, that I plant one right outside of his pool room. Last year it was infected with Rose Rosette Disease, a tiny mite that originated from the multi-flora wild rose. The microscopic mite is so tiny it’s all but invisible to the naked eye. All or shall we say any rose can be susceptible that’s why we must remain vigilant watching for infection in our gardens and remove any infected plants immediately. carefully. It can be transmitted by the wind. Signs of it are a witches broom growth reddish type growth beginning at the top of your plant. A sure sign is lots of thorns. As of yet there are no cures but some roses are resistant like ‘Top Gun’, and some of the ‘Rosa Rugosas’.
‘Top Gun’ Resistant To Rose Rosette Disease
‘Double Knock Out’ with RRD
Last year my rose apprentice Drew Carroll and I thought we had completely removed this bush but undoubtedly we had not. It came back clean from the root and after I came back from the Biltmore Rose Trials the strange growth appeared again so we were wrong. I went to leading RRD expert Dr. Mark Windham’s class at the Southern Il. University Extension Class at Decatur, IL to a packed class of the Master Gardeners and the Stephen F. Decatur American Rose Society and this is exactly how he instructs removal of Rose Rosette Disease safely and effectively.
Summer Time of Easy Livin’ Sets The Stage For Catching Up In The Garden
Itâ€™s the dog days of summer. Vacations abound. Excessive heat can create conditions for your roses to produce smaller blooms and stunted growth to preserve water. Now is the time to prepare for a glorious fall rose display. Whether your roses have been subjected to extreme heat or lots of rain you can rejuvenate them with a few simple steps.
Roses Are Forgiving Now’s The Time To Get Ready For A Fall Super Bloom
I’ve said many times “Roses Are Forgiving”. So whether you’ve neglected your roses over the summer or taken great care of them it doesn’t matter they can bounce right back and produce a beautiful fall bloom with a few easy steps. Excessive rain can wash away nutrients and heat stresses the plant during the growing season. During August do a few simple steps and you can sit back in your fall rose garden sipping your favorite beverage with friends enjoying the luxurious fall rose bloom. So before you pack-up the kids for the last summer fling have the kids get out there to put down a couple of cups of Espoma Organic Rosetone around each rose bush. Be sure they have plenty of water and you’re on your way to seeing a glorious fall bloom.
Here’s How To Cut Back Your Roses For A Fabulous Fall Bloom
A good rule of thumb is to prune your rose bush about one-third to one-half their height.
Prune out dead wood.
Leave the strong hardy canes.
New rose bushes only need to be dead headed.
“Rose Shows and State Fairs require planning and dedication to the cycles in days it requires to cut back your roses to produce the rose to show a qualifying rose at your local events. So start your planning now.”
Folks that show roses cut back for the rose shows in their area or for the County and State Fairs. If you plan on showing in your local rose shows then cut back your roses based on this handy guide to approximately how long it takes to produce a rose on each type rose:
Repeat Rose Cycles In Days
Hybrid teas, grandifloras, and floribundas: 42 to 54 Days
Multi-Petal Floribundas (Europeana): 54-60 days
Single Petal Floribundas (Playboy) 35 Days
Miniatures 35-42 Days
August is the time to prepare for a spectacular fall rose bloom
September, October, November and even up until Christmas, fall is perfect throughout much of the country to spend time in your rose garden. You can enjoy the fruits of your labor, contemplate strategies for expansion and begin to winterize your roses. The cooler temperatures of fall create a glorious canvas for the fall rose show. It’s time now to begin the process of cutting back roses for your fall bloom. ‘Kimberlina’, a ‘Floribunda of the Year’ 2009 winner is such a spectacular rose in the fall I chose it to show you how to cut back your roses to create a spectacular fall bloom.
Cooler Temperatures of Fall Intensify Colors
Cooler temperatures in fall create a palette of colors that makes your roses look doubly magnificent. From Wisconsin to Texas Iâ€™ve seen roses continue to bloom through the holidays. Roses can tolerate 3 days of hard frost of temperatures below 21 degrees before they are fully dormant for the season. So you can plan on roses for your bouquets for the Thanksgiving table in Illinois, maybe even Wisconsin. September is time to determine if there are still any American Rose Society rose shows in the area you may want to exhibit at as well.
Here are some ‘Rose of the Year’ winners and roses exclusive to Jackson & Perkins that I’ve grown from IL to Texas successfully that bloom beautifully all season and into the fall:
This week I pruned the Oso HappyÂ® Oso EasyÂ® Roses with the hedge clippers! Yes. The hedge clippers. My husband was thrilled. One rule applies to the roses: “Rose thorns may not tear off my clothes as I speed by at speeds previously never seen before the zero-turn was purchased.”
Now the Proven Winners Oso Easy Roses are pruned like boxwoods in an English style prim and proper hedge. The Oso HappyÂ® with Oso EasyÂ® roses were planted in the fall to show you they are indestructible. Here’s the rotogravure of what the Proven Winner Oso HappyÂ® with Oso EasyÂ® rose bloom has looked like all year.
Today time and investment are factors that affect our decisions in everything we do. Most folks tell me I would have a rose garden if I had the time or roses weren’t so difficult to take care of. Shannon Downey at Proven Winners had asked me to try something new; plant Proven Winners shrub roses in the fall. So I planted all the Oso HappyÂ® and Oso EasyÂ® roses in the fall.
Brilliant Rose Breeders Creating Better Roses
David Zlesak, is a rose breeder that has been doing remarkable work to develop winter hardy, disease resistant roses. He works to create roses that are resistant to the scourges that have plagued roses over the ages and have kept folks from growing roses. ‘Above and Beyond’ is his remarkable apricot climber. Dr. Zlesak sent it to me to test grow after I had returned home from being invited to speak at the Twin Cities Rose Club in Minneapolis, MN. Many of the ‘Oso Happy’ roses were created by David Zlesak.

‘Oso Easy’ Double Red by Alain Meilland
This rose is spectacular. I planted it in the fall along with all of these Proven Winner Oso Easy Roses that Shannon Downey sent me. We agreed to conduct our own test. I have never planted roses in the fall. It subsequently was the coldest winter in Illinois recorded weather history the winter of 2013. This is the second season for the Proven winner shrubs. Last winter the temps were were down to zero. I’m happy to report not one Oso HappyÂ® or Oso EasyÂ® rose was lost to the winter cold. Thank-you to Proven Winners for making these wonderful roses available to the world hybridized by world famous rose hybridizers all listed below: the Meilland Roses International and Chris Warner, UK.

A cool spring allows the tulips to linger, every little narcissus, jonquil, and daffodil its day in the sun and spring blooming trees to sway in the breeze just a little longer for us to treasure. Susan Fox

What A View While Fertilizing The Roses
The cool spring allows us to be able to be outside longer and enjoy the treasure trove that the spring bloom and fragrance the garden has to offer. I can’t remember a spring that has been more generous in the length of bloom cycles. So just take your time and enjoy while it lasts. Summer will be upon us in no time and the roses will be in bloom.
Flowers that produce big beautiful blooms in the shade or filtered light are far and few between. The Butchart Gardens a group of floral display gardens in Brentwood Bay, British Columbia,Â Canada, located nearÂ Victoria on Vancouver Island that have been designated a National Historic Site of Canada, is the first time I saw tuberous begonias planted in the ground everywhere blooming in filtered light to near shade.
Tuberous Begonias In Containers
Colorful Shade Companion Plantings
After visiting Butchart gardens I immediately remembered my mother had planted tuberous begonias in window boxes completely in the shade outside the living room window in Northern Illinois and they bloomed all summer long producing beautiful huge flowers of multiple colors. So I was on a search to find them. Marketed at the time in N. Dallas as Non-Stop Begonias I bought them and planted them in the ground in the shade for dramatic color all summer long.
Big Box Find – Tuberous Begonias
Red & Yellow Planted or Placed Near The Rose Garden
Once I asked a horticulturist if the begonias could be planted in the sun and they asked me a profound question.
Compare Foliage With Fibrous Begonias
With so few plants that produce beautiful blooms in the shade why would you want to plant this begonia in the sun?” Good question. If you are looking for the shade color companion look no further than tuberous begonias.
Winter Care For Tuberous Begonias
For care the tubers need to be dug up once they are dormant and placed in a paper bag, and stored in a cool dark place for winter. I’ve brought my pots in for winter and they have started all over again many a season just leaving them in the pots. Here is a complete guide of the Lost Art of Growing & Caring for Tuberous Begonias. White Flower Farms have a complete array of spectacular tubers available with 20% off.
Color ‘Made In The Shade’
Begonia (Tuberous Begonias)
Latin Name Pronunciation: beg-own’ee-uh
Tuberous Begonias are frost-tender plants that thrive where they receive bright light but little or no direct sun. Given an early start, they put on a glorious display all summer long. We grow our Begonias in pots and hanging baskets, but they can also be planted in the ground (once the danger of frost has passed). Either way, unless you live in a frost-free climate, you must lift and store the tuberous roots in fall to carry the plants through winter.
Starting Tubers in Flats or Pots
To get a jump on a short season, plant tubers on arrival in flats (shallow containers with drainage holes) or 4â€“5â€³ pots.
The potting mix should have a light texture and be well drained; a soilless mix, mixed 3 to 1 with builder’s sand, meets both requirements. Begin by placing potting mix and sand in a plastic tub or bucket. Slowly add water and stir until the mix is moist but not soggy. Put moistened mix in the container, stopping about 1Â½â€³ shy of the rim.
Handling the tubers with care (especially if they have begun to produce new growth, which is very fragile), place them, hollow side up, on top of the potting mix. Space the tubers 2â€“4â€³ apart in a flat (one tuber per 4â€“5â€³ pot) and cover them with Â½â€³ of potting mix. Then water sparingly and place the container in a window that provides bright but indirect light.
Keep the potting mix moist but not soggy.
To hasten growth, set the container on a heating mat or a radiator (with a few magazines between container and radiator to prevent overheating). Tubers that have not already begun to sprout when you receive them will generally show signs of growth within 2â€“6 weeks after planting.
After the first 2 leaves have emerged, transplant tubers started in flats into 4â€“5â€³ pots or, provided the danger of frost has passed, into a lightly shaded outdoor bed that has been amended with organic matter such as compost or peat moss.
Lift and move the tubers carefully to avoid damaging the roots, and set the top of each tuber 1â€“2â€³ below the surface of the potting mix or garden soil. Begonias planted in the ground should be positioned so that the points of the leaves aim at the viewer, because the blooms will face the same direction.
Plants in 4â€“5â€³ pots should be moved into 7â€“10â€³ pots when the roots fill the pots. If time and energy permit, a final move to 12â€³ pots will yield especially spectacular plants.
Set pots outdoors in a bright but not sunny location when the threat of frost has passed. Tuberous Begonias will not grow well in deep shade.
When upright varieties are 4â€“6â€³ tall, push a heavy, 18â€“20â€³ long bamboo stake (or one of our cushioned, steel Begonia Stakes – Set of 5) into the potting mix or garden soil on the side of the plant opposite the points of the leaves. Place the stake a few inches away from the main stem to avoid injuring the tuber.
Fasten the plant to the stake with garden twine or soft plastic tape looped in a figure-8 around stem and stake. As the plant grows, you may need more ties to provide additional support.
Tuberous Begonias thrive in soil that is evenly moist but well drained. Soggy soil can cause the stems to snap off at the base.
Fertilize plants once a month with a balanced (20-20-20), water-soluble fertilizer mixed as directed.
Keep plants tidy by removing spent flowers; cut the flowers off close to the stem using a sharp knife.
The only disease that may trouble your plants is powdery mildew, a fungus that appears as white powder on the leaves. Powdery mildew is easier to prevent than it is to cure, and placing your plants in a location where air can circulate freely around them is the best prevention. If you’ve had trouble with powdery mildew on Tuberous Begonias in the past, you can prevent future outbreaks by spraying with a mild fungicide that you can prepare yourself by mixing one tablespoon of baking soda and 2 or 3 drops of insecticidal soap in a gallon of tepid water. Spray this solution every 10 days during hot, humid weather. Once mildew appears, the only effective remedy is to spray promptly with a commercial fungicide. Follow the directions on the label carefully.
Allow plants to grow through November (or until frost) to store energy for the next season.
Force container-grown plants into dormancy by gradually withholding water.
Dig plants grown in the ground with a ball of soil and let them dry out in a shed or on the garage floor.
When the stems break free from the tubers, shake off excess soil and allow the tubers to cure in the sun for about 4 days. Then store them in dry peat moss or sand in open flats in a cool (45Â°â€“50Â°F), dry place.
Replant the tubers as suggested above in late winter.
Growing Hanging Basket Begonias
Hanging Basket Begoniasâ€”varieties with trailing stemsâ€”require much the same care as upright Begonias, except that they look their best in a shallow container that can be suspended from the eaves of a house or from an arbor.
One Hanging Basket Begonia tuber in a 12â€³ container makes for a spectacular and long-lasting display.
If the stems of a Hanging Basket Begonia grow upright and refuse to trail over the edge of the container, plants are not receiving enough light.
