A rose by any other name still needs spring care, says Minter

Today’s new roses are not only long and continuous blooming but also hardy and very disease resistant, Brian Minter writes.

Versatile shrub roses are easy to care for and provide great ground cover.

Roses are now bursting out with buds already showing and even some colour.  However, I am absolutely amazed to hear of aphid problems already on roses and would highly recommend simply washing them off with a gentle flow of water.  In terms of sprays, if you wish to stay organic, use Safer’s ‘Trounce’ every 10 days as a foliar mist.  To keep mildew and black spot in check, pick off any infected foliage and every 10 days, alternate an application of old-fashioned garden sulphur with an application of a baking soda solution (8 grams per one litre of water) mixed with a teaspoon of Trounce to act as a spreader-sticker so the spray adheres to the leaves.  It works!  I am also very impressed with the new biological organic fungicide ‘Natura’ which contains bacteria that feed on a wide range of funguses.

In spite of roses being slightly acid loving, they still need well-rotted manures.  Fibrous manures, such as mushroom compost, are dandy and should be applied at least four to six inches deep around your roses.  If you covered the bud unions of your roses in winter with bark, sawdust or soil, remove it now and work it into the soil along with the manures.  Roses are heavy feeders.  There are many organic and traditional rose foods on the market, but be sure they are rated low nitrogen, high phosphorus and high potash with micronutrients.  Roses should be fertilized every two to three months.

There are some interesting new roses out that are very disease resistant.  Bailey Nurseries has introduced a series of roses, called ‘Easy Elegance’, that have great hardiness, attractive flower forms, compact size, recurrent blooming habits and yes, great disease resistance.

I’m also very intrigued with the roses from the famous Kordes family, who have been growing roses in Germany for four generations.  Their whole series of hybrid teas, grandifloras and floribundas are very disease resistant, repeat flowering and many are highly perfumed.  ‘Grande Amore’ and ‘Beverly’ are reputed to be among the best red and pink roses available today.

I’ve seen quite a shift in demand, moving away from the traditional modern rose varieties to the more versatile shrub roses and to ground cover and easy care, disease free, hardy, continuous blooming varieties.

‘Floral Carpet’ roses have been around for some time now and are mostly used as ground cover roses, but their continuous colour, tenacity and disease resistance places them among the best.

The newest series of ground cover roses, called ‘Drift’, have slightly smaller blooms, but are amazingly prolific, and with their shiny disease-resistant foliage, they look very promising.

Yes there are old-time favourites out there that we all appreciate, but today’s new roses are not only long and continuous blooming but also hardy and very disease resistant.  These are just some of the great ones on the market, and they are bringing back roses into the garden again.
