Pruning roses

When am I supposed to prune my roses and by how much? 

The best time to prune your roses is in late winter, early spring  just as you see that the leaves are starting to bud out.  Pruning before then runs the risk of additional frost injury.  When you prune them, you will be removing dead wood, weak and crossing branches.  How much to remove depends on the gardener’s own goals. 

Rigorously pruned rosebushes have fewer flowers, both at the first flush of bloom and throughout the season than do plants pruned more moderately.  Drastic pruning can produce coarse flowers and reduces the food supply that is stored in the stems.  Continuous cutting back year after year lessens the vigor of the bushes. 

Keeping in mind that it is desirable to allow as much sunlight and air as possible to reach the center of the plant to help prevent disease.  Canes growing inward should be removed and cuts should be made just above an outward-pointing bud so that the new growth will be started in the right direction.  Cutting canes that are four or more years old to the ground will encourage base stems to cover the bare bottoms of most hybrid teas.

How to Prep Your Garden for Roses

Roses like good drainage and are heavy feeders, so we like to make sure that no matter what your soil type that you add as much compost and/or well rotted organic matter into the mix of the rose bed to make a loose friable growing space.  Sand can be added too, but it does not open up air spaces in the soil like organic matter does, so it should not be the only additive, particularly when dealing with clay soils.  You do not want to create a ‘clay pot’ effect so make sure that you mix the garden soil well into your rose bed mix.  

If you are planting bareroot roses it is very important to dig a hole that is at least 2 feet wide and deep in order to place the roots at the proper depth.  If you live in growing zones 5 and colder it is best to bury the graft knot at least 1”-2” below the soil level for winter protection.  Mulch is very important in the planting of roses.  This material keeps rain water from splashing mud up onto the leaves and flowers.  Keeping soil off of the leaves and flowers helps to keep diseases, like black spot and mildew, from forming and spreading.  

Drip irrigation is a wonderful way to be sure that your roses get plenty of water without getting their leaves wet.  This can be set in place after planting and covered with your mulch of choice to keep the water cooler in summer.

New Roses for Spring 2012

Tropical Sun Floribunda roseThe winter holidays are here, and for our friends in the southern most parts of the country, it is time to think about planting roses.  Here at Jackson and Perkins we have roses bareroot and in containers for spring planting.  New for this year is a sunny faced floribunda called Tropical Sun. 

Double Red Simplicity Hedge RoseWe also have the perfect hedge rose with a double red flower.   At 36″-40″ tall it produces a beautiful neat hedge full of lightly scented flowers.

Check out the new spring line at http://www.jacksonandperkins.com for these and other great roses.  The full spring line should be on line by the end of December.

Roses for New England

Living in the  New York and New England areas, the winters can be very cold, and the soil is sometimes a heavy clay composition.  If you would like to plant a rose garden, the best roses for the  area would be shrub roses or floribunda roses that are more cold hardy and can withstand the winter conditions.  The large-flowered hybrid tea roses are beautiful, but they would have a more difficult time adapting to and surviving conditions there, so we would not recommend them. Amend the clay soil with organic materials such as peat moss, compost, and old manure to make a good rich soil for roses.

Flower Bulbs Make Gardening Easy

Crocus 'Pickwick'

They are beautiful. They are inexpensive. They are extremely low maintenance, and most of them will continue to come back every year, spreading and naturalizing in your garden. Flower bulbs should be one of your yearly gardening staples, a go-to problem solver.

They are so varied and adaptable – you can buy irises and lilies that will grow in standing water or perhaps a tulip, crocus, or hyacinth cultivated in dry Mediterranean climates. These plants will stand up to the toughest droughts. Bulbs can be a hardy practical way to fill dull spots in your landscape design.

Because the bloom seasons vary, you can create a bulb garden that is always full of blooms and constantly changing throughout the year. This can be difficult if you are buying your bulbs from a bin – you may want to ask your local nursery attendent for assistance, but if you are shopping for garden bulbs online, Jackson & Perkisn will always include approximate bloom times in the product descriptions.

Quick Guide to Watering Roses

Roses love water – they can be some of the thirstiest plants in your garden. The local climate and soil type can affect the moisture needs of an individual plant. You will have to come up with your own watering schedule, but the important thing to remember is regularity. An inconsistent watering schedule can be as damaging to your plant as heavy rains or drought.

Always water deeply – light waterings lead to shallow roots and weak plants. If you soak the ground the roots will grow deep and the plant will become strong an established. Water at the base – overhead watering will lead to wet leaves and a proclivity to fungus and disease. Watering at the base also ensure that the plant directly receives enough moisture.

Water well when the plant is young to ensure more resilience later on. An established rose bush with a deep root system will fair better against sudden changes in moisture levels, thriving through tough droughts and heavy storms.

Using Floribundas For Cut-Flowers?

Not your typical cut-rose, Floribunda roses are usually the roses that attract the most attention in the garden. They are more hardy than many other varieties, and their tendency to remain in full bloom throughout the growing season makes them a remarkable addition to any landscape design.

Though they lack the long stems and statuesque appearance of Grandifloras and Tea Roses, their abundance of perfectly sculpted blooms makes for a spectacular dining room centerpiece or decorative bouquet. There is nothing that will brighten a room quite like a real live cut-flower arrangement. And, because all varieties of Floribunda roses bloom throughout the season, you can mix and match for a dazzling display or colors and sweet fragrances to flood your next dinner party with praise and conversation.

Growing Roses in Containers

Wild Thing Shrub Rose
Most rose varieties can be grown easily in containers, everything
except the largest climbing roses. Growing roses in a container is not
really any more difficult than growing other plants in containers.
  • Your container must be large enough to house mature root system (usually about 15 inches tall and wide).
  • Your container must have good drainage – do not use a container that doesn’t have drainage holes in the  bottom
  • Use high quality, nutrient rich soil. Commercial potting soil is perfect, but amending it with equal parts compost and manure will really give your rose a running start.
  • Place your rose where it can receive enough light. Most rose varieties prefer full sunlight – think about placement beforehand to save yourself some trouble.
Potted plants use nutrients much more quickly than if they were planted
in the ground. Use an all-purpose rose fertilizer once every other
watering, and/or work a rich compost into your soil mixture. You will also
need to water more often with potted roses because the soil moisture
will evaporate more quickly. Roses need a deep watering, but they will
rot if they are perpetually moist. Stick your finger into the soil to test – if
it is dry it is time to water again.

If you want to try growing roses in containers here are a couple of
suggested starter varieties that will be relatively easy to grow: Happy
Chappy Groundcover Rose
is a very hardy, weather tolerant rose that
responds well to container gardening; Wild Thing Shrub Rose is a
compact shrub rose with glowing coral blooms, perfect for container
gardening and landscaping.

Growing With Trellises and Arbors

Arbor With a Bench

Jackson & Perkins offers many garden structures including arbors, trellises, and arches to aid in growing your climbing roses and perennials. Climbing roses are gaining in popularity, and everyone wants to have the fairytale garden that seems to overflow with mounds of deep colorful blooms. The truth is, it’s not too difficult. With the right rose, and a sturdy arbor, you can have a wall of flowers that will incite envious stares from the whole neighborhood.

Training your plants to grow on a trellis is easy with plants that naturally have a tendency to climb. Just use little pieces of string to guide them along the way. Mind your strings that they don’t inhibit growth or cause damage to the plant. Once your plant is matured, it and the trellis will be inseparable, a dense wall of beauty.
