The Rural Voice, 1997-03, Page 39Gardening Hardy roses rekindle love affair By Rhea Hamilton -Seeger I think I have fallen in love again with roses. Many years ago I bought a number of rose bushes — hybrid teas and grandiflora varieties. I was plagued with black spot, aphids, and could have been charged with neglect for lack of nutrients to produce the magnificent rose bushes of my youth. With time the roses became integrated into my perennial border. When they bloomed they were praised and when they suffered they were cleaned up and ignored. But like so many others, I am a sucker for a well-turned petal, a blush of pink on apricot or a whorl of leaves around a perfect bud. So I succumbed to my nostalgia and bought a number of hardy roses born and bred in Canada. These roses were part of the Explorer series developed in the early sixties in Ottawa and further enhanced at the government breeding facility at L'Assomption in 1986. 1 dug in plenty of well -rotted manure, soaked them well when planted and used a thick mulch of bark chip. Every year they complete for Tight and space with a thick smothering cover of wild sweet peas and every year they bloom and prosper. Once the pea blossoms begin to go to seed you really notice the roses which bloom far longer. The Explorer series was bred for hardiness, disease resistance and perpetual flowering all summer.

Five of the 16 Explorer roses are cross -bred with Rosa rugosa, a very hardy shrub rose. The lovely double pink and high -scented Jens Munk is one of these and is very hardy. William Baffin (I think it is deep pink but pictures show it as medium red) is one of the pillar -type Explorers and could be classed as a climber. The Explorers are not grafted onto hardy rootstock but are grown on their own root system. As I skip through my catalogues I notice they are not offered this year so you will have to check your local nurseries. They are well worth the search. I have noticed, this year, a real push to promote the Parkland series of roses developed in Morden, Manitoba. While they share a similar hardiness to Canadian winters with the Explorer series, there are some basic differences between the two. The Explorer series was developed for humid regions of Canada while the Parkland series does better in drier regions. Parkland roses are therefore more susceptible to mildew and black spot than the Explorers, but of course mnch less than many other varieties. Rose Morden Blush, Morden Fireglow, Morden Centennial are all part of the Parkland series. These shrub roses are extremely hardy, need no winter protection and lend themselves easily to single specimen planting or an informal hedge. Once you have your favourite rose home, pick a sunny location that provides protection from strong winds. Roses need at least six to eight hours of sunlight a day. Remember sunshine also hinders mildew and other moisture -borne diseases. You can plant bare -root roses in the fall or early winter when they are dormant but for best results save the planting for spring. Dig up a good area, working in lots of organic material — leaf mould, compost or well -rotted manure. The hole should not be deeper than the soil line on the rose but should be twice as wide. Rose roots like to spread out like tree roots. If the root ball is matted, carefully tease roots out and spread thcm in the hole. Now we come to the graft. I used to have problems determining if it should be below ground where it could be protected from the winter cold or above the ground so it did not encourage suckers to sprout close to the graft. Got the riddle solved. Grafted roses should be about four inches (10 centimetres) below ground level except in Zone 8 and higher where the bud union should be just above ground level. Pruning at planting time forces the growth into key areas. Prune back to several stocky shoots with a few vigorous buds on each. Always have the buds facing outwards so that the new branches will grow outwards leaving the centre of the plant open. And last but certainly not least ... mulch. This keeps the temperature even, keeps the moisture in, discourages weeds and keeps harmful soil/water-borne diseases from splashing on the leaves. Roses are big feeders and if you have added lots of well -rotted manure etc. then you can use a balanced fertilizer or special rose food early in the season and twice more before mid-July. Feeding later than this encourages new growth that won't survive the winter. For years we have looked to both the tropical south and the gardens of Europe for our designs, inspirations and new additions to our gardens. It hasn't been until recent years that gardeners have sought out the beautiful in their own native habitat. With the addition of hardy Canadian - bred roses, gardeners are enjoying the best of the breed and encouraging the rest of the world to enjoy a piece of Canada too.0 Rhea Jlamilton-Seeger raises two children, and is a skilled cook and gardener.
