FERTILIZING ROSES: THE BASICS AND TIMING

“For everything there is a season ..."

 ... and for fertilizing roses in the upper plains of South Dakota September 1 means:  STOP.  Use Labor Day as a target for a reminder--Let those precious plants slow down and get ready for winter. 

So much for stopping—this article is intended to discuss the basics of fertilizer and fertilizing rose bushes.  Roses are heavy feeders.  They can survive without being fertilized but they will struggle.  To perform their best, roses need a continuous source of nutrients during the growing season not only to provide lush blooms, but to fend off insects and disease.

So, what do we need to know to keep our babies healthy and productive?  SEE THE FULL ARTICLE

HOW TO WINTERIZE ROSES IN ZONES 2-5

The goal in winterizing roses is to prevent your rose bushes from freezing and thawing.  This freezing and thawing is very damaging to them.  There are a lot of different ideas on how to winterize roses.  The following tips are a summary of what I feel is some of the best information for winterizing roses.

  1. Water your roses well in the fall until the ground freezes.

  2. Do nothing if you have hardy roses that are labelled for your zone.  They should not need any special treatment as long as they are mulched well and not out in the open and subjected to cold winter winds.

  3. Wait to winterize your roses after there have been a couple of hard freezes.  This advice may be difficult to follow some years as the snow may fall before the ground is frozen.

    1. Hill up loose soil around the base of the plants in really cold zones especially if your rose is not hardy for your zone.  Do not scrape the soil from around the plant, bring in extra soil.  Soil should cover the center of the rose and form a mound.  The mound can  be covered with mulch, peat moss or crushed leaves.

    2. Or set a large pot or tub without a bottom over the rose to protect it.  You can fill the pot or tub with leaves but be aware that rodents are attracted to these cozy spots and they like to chew on roses.  Sprinkling rodent deterrent granules in with the leaves or mulch should help keep them away.  Peat moss or mulch could be used also.  SEE FULL ARTICLE

WHAT TIME OF YEAR DO ROSES LOOK THEIR BEST?

June Flush

June is the month that we get to see the first flush of rose blooms and it is usually the biggest and best flush.

 

Depending on the amount of rain received, and other things such as heat and humidity, roses may put on another show in other summer months - but it’s usually not as glorious as the June flush.

 

Keep Them Blooming

Most roses will continue with light to moderate blooming well into fall if they are consistently dead headed and watered well.  Deadheading is the removal of spent blossoms thus preventing the hips or seed pods from growing.  

When to Plant for Best Blooms

Early May is the time to plant bare root roses.  If you are planting roses purchased in containers, late May and June are ideal.  If you haven't planted containers by August 1, it is best to wait for next year to plant them.

HYBRID TEA ROSE SURVIVES DESPITE WINTER CHALLENGES: A SUCCESS STORY

'Love at First Sight' is Disease-Resistant

"Love at First Sight" is a hybrid tea rose released in 2020.
This one was acquired through the North Central District of the American Rose Society. Research shows this disease-resistant hybrid tea was developed by Bedard for Weeks Nursery.

Surviving Winter's Vagaries

Rather than risk losing this bush to our Zone 3b winter, it was potted for the patio for summer 2020 with the intent of overwintering in our garage. After a summer of prolific blooming, it went dormant and was garaged, only to break dormancy during Aberdeen's heat wave of October/November. Rather than strip the leaves and try to reintoduce dormancy, I opted to bring it into the house and nurse it through to another spring/summer on the patio. So far so good.

 

A Fresh Bloom in February

In February, it produced this bloom, and recently survived an attack of spider mites, refoliating itself after being heavily sprayed down with a Dawn soap bath.

 

Characteristics

Petals of this bicolor beauty are red on top and deep pink, fading to a white underside as the bloom opens. It has a 5- by-3-foot spread, with a mild, fruity fragrance. It can be hardy from zones 4 or 5 to Zone 10. The blooms on this newbie are on long, slender stems and are smaller and more rounded than older varieties of teas. This appears to be an up-and-coming trait being developed in the industry.
